Background: The number of image diagnostic examinations is increasing. There is a need to implement guidelines for referrals to the X-ray department. 20% of all DT examinations are deemed not to be justified. In 2017, implementation and translation into local conditions of iGuide in trial was initiated in one of Sweden's regions. The aim: The aim is to study the experiences of radiographers and radiologists from the justification of examinations in the X-ray department. Method: An empirical study with qualitative design. The inductive approach was applied. Semi-structured interviews were applied with licensed radiographers and radiologist. The interview material was analyzed with a manifesto content analysis. Results: The analysis resulted in the following subcategories: The meaning of justification, The shared responsibility in justification, Unjustified referrals and actions, Remittent and patient impact on justification, The organization impact on justification, The accessibility of various modalities affect justification, IGuide is based on the problems of justification, and The results of the iGuide-project. The subcategories form three categories: Justification of examinations, Existence of unjustified examinations, and IGuide as a means of achieving increased justification. Conclusion: X-ray utilization is increasing and thus the problems with justification. The radiologists experience that the lack of time affects justification negatively, also that the remittance often has difficulty in denying patients. Radiographers experience that communication between departments is important for justification. The increased range of modalities is described as affecting. IGuide increases the proportion of justified examinations, and reduces the number of requested imaging examinations, but the system needs to be given a greater user-friendliness.

This research approaches the importance of the waters of Ribeira de Iguape River to the history of Ribeira Valley. This river has been exploited since the beginning of the colonization. In the sixteenth century, expeditions used to search for precious metals from river mouth. In the following centuries, the waters continued to be exploited and precious metals were discovered in the Upper and Middle Valley, where metal mines were established. In the late eighteenth century, mining went into decline and rice began to be cultivated on a commercial scale. The rice crop followed the bed of the Ribeira River and its tributaries, due to the fertility of soils, the energy devices to move water and the docking sites for canoes. Between the seventeenth and nineteenth centuries, many Africans landed in the region to work in mines and plantations. Africans and Europeans inscribed in the waters of Ribeira River their myths and beliefs, among them, we will highlight the water negro (negro dágua). Also, in the same waters it was washed the image of Lord Good Jesus of Iguape, the most celebrated saint of Ribeira Valley. The Ribeira river were also utilized for rites of divination and healing. Myths and beliefs were analyzed within the Atlantic perspective, understanding the cultural formations created on American soil as compiled from the meeting of diverse people, brought into contact under slavery and owners of different worldviews. We discussed the evangelization occurred in Central Africa and in Ribeira Valley, then we highlighted that, on both sides of the Atlantic, the catholicism was reinterpreted according to local beliefs. We also analyzed the presence of African beliefs in the Ribeira Valley, especially the cult of the dead and the rites of divination and healing.

According to the United Nations (UN), the target of one of the objectives Development Goals of halving the number of people without access to water drinking was reached - however, 768 million people still do not enjoy this advance overall, especially in rural areas. In this context, the population of Iguape, a district of municipality of Aquiraz-EC, is part of this minority, lacking sewage and supply for water distribution network. Thus, a study was performed to During the year 2013 with the objective of determining if the water wells used by population - the main source of those goods - was in accordance with the parameters of potability provided for in the regulations. The results show that for the plurality of wells human consumption have parameters outside the limits accepted by the existing laws - presence of E. coli, for example. As a reference for this study the Quality Index Canadian Council of Ministers of the Environment was employed to facilitate the Understanding of the data set and revealed that the ten wells monitored only one presents water quality rated as Good.
Segundo a OrganizaÃÃo das NaÃÃes Unidas (ONU), a meta de um dos Objetivos de Desenvolvimento do MilÃnio de reduzir pela metade o nÃmero de pessoas sem acesso a Ãgua potÃvel foi atingido â entretanto, 768 milhÃes de pessoas ainda nÃo usufruem desse avanÃo global, especialmente nas Ãreas rurais. Nesse contexto, a populaÃÃo do Iguape, um distrito do municÃpio de Aquiraz-CE, faz parte dessa minoria, carecendo de coleta de esgoto e de abastecimento por rede de distribuiÃÃo de Ãgua. Dessa forma, foi realizado um estudo ao longo do ano de 2013 com o objetivo de verificar se a Ãgua dos poÃos utilizados pela populaÃÃo â principal fonte desse bem â estava de acordo com os parÃmetros de potabilidade previstos nas legislaÃÃes vigentes. Os resultados mostram que diversos poÃos destinados ao consumo humano tÃm parÃmetros fora dos limites aceitos pelas legislaÃÃes vigentes â presenÃa de E. Coli, por exemplo. Como referÃncia para esse estudo o Ãndice de Qualidade do Conselho Canadense de Ministros do Meio Ambiente foi empregado para facilitar a compreensÃo do conjunto de dados e revelou que dos dez poÃos monitorados apenas um apresenta Ãgua com qualidade classificada como Boa.

Iguape is one of the cities on the southern coast of São Paulo State that had great importance in the History of colonial Brazil. It had its days of glory during the rice plantation period, when Ribeira de Iguape River was the main means of transportation and the port on its banks was one of the most important in the country. Later, decline came as a consequence of the opening of Valo Grande and the aggradation of its port. Finally, it became isolated in one of the poorest areas of the São Paulo State, the Ribeira Valley. Iguape is point number 334, as indicated by Antenor Nascentes, for the research of the Brazilian dialectal reality. The present work aims at registering samples of this truly \"caiçara\" dialect, in a region of \"tupinisms\", archaisms and peculiar lexical variants. We intended not only to place the lexias used in the area on a map, but also to list the most frequent ones. Besides doing quantitative treatment to data, based on Muller\'s notions of Lexical Statistics, we have focused in approaching the semantic-lexical aspects, based on Pottier and Rastier and starting from Coseriu\'s notion of norm. Based on present Geolinguistics theoretical-methodological procedures, we have applied the questions from area \"Human Body\" in the semantic-lexical Questionnaire of Project AliB, version 2001, in three points of the city of Iguape - namely Icapara, Rocio e Jairê -, to twelve subjects, four in each point, from both genders and belonging to two age groups, between 18 to 30 (first group) and older than 66 (second group). From the answers obtained in interviews, we have elaborated sixteen cartograms, which reflect the diatopic variation on lexical basis. Still in consonance with the principles of modern Geolinguistics, which allies its methodology to the one used in Sociolinguistics, forming a pluridimensional framework, we have showed the picture of local linguistic diversity. In summary, this work registers the linguistic reality of this very small part of Brazil, which has great importance to geolinguistic studies, before the loss of these speeches, be it by the homogenizing effect of mass media or by language\'s own centrifugal forces.

The Cananéia-Iguape system is a huge complex of lagoon and estuarine channels, located in the south of São Paulo State. This system received the waters of Ribeira de Iguape River, after the construction of the Valo Grande Channel, an artificial channel which was concluded in 1852. This channel became an important route of transportation of the agricultural production from Ribeira Valley, reducing the transportation time and cost. From 1940 and 1990, the mining activities of the region contaminated the waters from Ribeira de Iguape River, changing the original characteristic of the Cananéia-Iguape system. This study evaluated the uranium and thorium concentration in superficial sediments samples from Cananéia-Iguape system. The evaluation was performed by a spectrophotometric method with Arsenazo III. The samples were digested with HNO3, HF and H2O2, on a microwave. The concentration of uranium varied between 1.3 mg·kg-1 and 5.8 mg·kg-1, and thorium concentration varied between 0.82 mg·kg-1 and 12.1 mg·kg-1. The results obtained were compared with literature values and were very similar. The geo-accumulation index was applied, and the region was classified as \"No contaminated or moderately contaminated\" for uranium and \"No contaminated\" for Th; indicating that the region is not contaminated by these elements. The results obtained can be considered as the baseline of the region. The statistical treatment of the results showed that U and Th presented a good correlation with the fraction clay and silt. The concentrations of U and Th did not present a homogeneous behavior along the system studied.

The mangrove is defined as a coastal ecosystem of transition between terrestrial and marine environments and is characterized by salinized environment and the constant flooding caused by tides. With emphasis in the area of coastal systems Cananéia - Iguape, its importance is more related to the production of biomass, inserted in the natural bioenergy system, that increases the productivity of the coastal zone with the introduction of organic particles. Represent plant communities adapted to different physical conditions in coastal areas, including the weather. This study aimed to analyze the changes of the attributes climate (air temperature, relative humidity, solar radiation, wind and rainfall) in the mangrove at the barra of Ribeira-Iguape/SP, checking if the variation is related to the main characteristics of vegetation, more specifically with the presence of the canopy at the environment. Was installed a tower containing two microclimatic weather stations to obtain an analysis of changes in climatic attributes above and below the canopy of mangrove. It was also analyzed the structural characteristics of mangrove, aiming to compare with the attributes climate. This research contributed to understanding the variation on the attributes of climate and its influence in the mangrove vegetation. It was found that, on the scale of work microclimatic, the attributes of climate have a direct influence on the spatial distribution of vegetation. Furthermore, the characteristics of the canopy are the main control for this variation, mainly in distribution of rainfall below the canopy and the amount of solar radiation, which consequently influences the distribution of plant species of the environment.

Trata-se de um estudo dos reflexos e relações existentes entre aspectos da cultura escolar moderna em uma escola situada no distrito rural de Santiago do Iguape, município de Cachoeira, Recôncavo baiano. Seguiu-se a um estágio curricular ali realizado – na área de coordenação pedagógica, no âmbito do curso de graduação em pedagogia e do Projeto Paraguaçu -, em se que evidenciou muitas tensões e dificuldades perante as demandas emergentes no cenário social contemporâneo. O objetivo principal foi de analisar os limites do paradigma educacional moderno em face tais demandas e, assim, contribuir para a compreensão de processos educativos – a serem implantados -, sensíveis a e consubstanciados pela diversidade dos grupos humanos e dos seus contextos socioculturais e históricos. Realizou-se um estudo de caso ancorado em uma abordagem metodológica de inspiração etnográfica, por meio do qual se buscou a aproximação e interpretação de fazeres ordinários produzidos na escola, valorizando o cotidiano e os sujeitos envolvidos na ação educativa. O trabalho de pesquisa e as análises desenvolvidaspermitiram a reflexão sobre os valores excludentes em relação à diversidade culturale dos sujeitos, - que, de forma subjacente, encontram-se imbricados no modelo educacional moderno e se propalam no cotidiano escolar -, assim como a conjectura de possibilidades de construção dos processos pedagógicos acima indicados.

Resumo: A presente dissertação procura discutir a gestão dos recursos minerais e do meio ambiente no município de Iguape (S.P.). Por ser o maior município do Estado de São Paulo em área territorial e por se tratar de uma região bastante complexa do ponto de vista ambiental, vários são os conflitos existentes no que se refere ao planejamento do uso e ocupação do solo, dado que o município apresenta quase 40% do seu território bloqueado por força do que dispõe as legislações ambientais que, a partir da década de 80, criaram várias Unidades de Conservação Ambiental e áreas correlatas. Dentre as atividades bloqueadas pelas legislações restritivas, destaca-se a mineral. Assim, vários são os conflitos de ordem sócioeconômica pois, se existe a necessidade pelos bens minerais, principalmente os de uso na construção civil, existe também a necessidade de conservação do meio ambiente. Os órgãos ambientais, por conta desta preocupação, proíbem qualquer atividade que implique em alteração ambiental propiciando uma atuação irregular e clandestina por parte dos extratores (prefeitura e particulares). Como forma de compensação às restrições impostas, o Estado repassa aos municípios que possuem áreas legalmente preservadas, valores da cota-parte do ICMS arrecadado, insuficientes para atender às demandas do município, assim como para atender às exigências ambientais impostas pelos órgãos federais e estaduais. Neste trabalho são discutidos os vários conflitos existentes entre a atividade mineral e a proteção ambiental, assim como a atuação dos órgãos públicos em relação à problemática em questão visando a compatibilização dos interesses conflitantes. Como resultado dos levantamentos referentes às atividades minerais e às unidades ambientais do município, são feitas sugestões que apontam para a necessidade de se manter determinadas lavras em atividade, desde que sejam mitigados os impactos negativos causados por esta atividade. Por fim, discute-se os impactos sócioeconômicos decorrentes da implantação de Unidades de Conservação Ambiental buscando, com isso, contribuir para um eficaz planejamento do uso e ocupação do solo no município
Abstract: The present dissertation quest argue the mineral resources and the environment management in Iguape (S.P.). That is the bigger municipal district in territorial area in the State of São Paulo, and too, environmental complex region where ocurrer many disagreement refering to the planning of land development, considering that the municipal district present nearly 40% this your land blockeaded to the economic activities refering to the environments legislations what in decade of 80 created varios Environment Conservation Units and correlated areas. Among the activities blockaded to the restricts legislations that import in the land development, emphasize it the mineral activity. Thus, the socio-economic conflits are varios, because to have the necessity for minerals assets, essentially the domestics minerals, and too the necessity for the environment conservation. The environments institutions, for this, prohibit any activity that implication in environment alteration, propitiating the irregular and clandestine actions for the extracts (citty hall and privates). By manner of compensation to the restrict imposed, the State repass for municipal district that have legally preserved areas, inssufficient values deriving from ICMS collected taxes, to attend the lawsuit of the municipal district, thus than to attend the environments exigences imposed to the institutions States and federals. In this work was discussed the varios conflicts existents between the mineral activity and the environment protection, thus than the public institution actuation refering the problems in question, looking at the compatibilization of the conflicting interests. How resulted of survey refering the minerals activities and the environment conservation units of Iguape are make sugestions that showing to the necessity of continue in activity determined mines, since than beeing profiled the negatives environments impacts.

The subject of this work was the coastal district of Iguape located in the city of Aquiraz, east coast of CearÃ, 38 km from Fortaleza. In recent years, there has been a change in tourism demand in that region and increased investment by both the public and private capital and international levels. Tourism is an economic activity that transforms space and reorganizes the territories and at the same time, generates social and environmental impacts to the cities where it develops. Thus, this study sought to understand the social and environmental changes of tourism on the coast of Iguape, characterizing their social and environmental conditions, and propose measures to achieve sustainable tourism in the region. For a better understanding of the environmental changes of the Iguape coastline, it was divided into: PresÃdioÂs beach, IguapeÂs beach and Barro PretoÂs beach, because they are most relevant in terms of tourism. Throughout this study were used concepts such as tourism, tourist attraction, tourist offer, tourist services, sustainable tourism, sustainable development, environment, landscape and environmental perception. The research was accomplished through reference books, observations, field surveys, questionnaires and interviews with local people, entrepreneurs, tourists and visitors being held at two different times, first in libraries, public agencys and then on the spot . From the interviews and questionnaires it was possible to better understand the view of tourists, residents and entrepreneurs on tourism held in the region, these often contradictory opinions, and understand the social and environmental transformations generated there by offering up alternatives to the achievement of sustainable tourism, like a global and participatory planning of tourism at the coast.
O objeto de estudo desse presente trabalho foi o litoral do distrito de Iguape localizado no municÃpio de Aquiraz, litoral leste do Estado do CearÃ, a 38 km de Fortaleza. Nos Ãltimos anos, tem-se observado uma mudanÃa na demanda turÃstica daquela regiÃo e um aumento dos investimentos tanto por parte do poder pÃblico como do capital privado nacional e internacional. O turismo à uma atividade econÃmica que transforma espaÃos e reorganiza territÃrios e, ao mesmo tempo, gera impactos socioambientais para as localidades onde se desenvolve. Desta forma, o presente trabalho buscou compreender as transformaÃÃes socioambientais geradas pelo turismo no litoral do Iguape, caracterizando suas condiÃÃes socioambientais e propondo medidas para a realizaÃÃo de um turismo sustentÃvel naquela regiÃo. Para uma melhor compreensÃo destas transformaÃÃes socioambientais o litoral do Iguape foi dividido em: praia do PresÃdio, praia do Iguape e praia de Barro Preto, por serem as praias de maior relevÃncia do ponto de vista do turismo. Ao longo da pesquisa foram utilizados conceitos como: turismo, atrativo turÃstico, oferta turÃstica, serviÃos turÃsticos, turismo sustentÃvel, desenvolvimento sustentÃvel, meio ambiente, paisagem e percepÃÃo ambiental. A pesquisa foi efetivada atravÃs de consultas bibliogrÃficas, observaÃÃes diretas, levantamentos de campo, aplicaÃÃo de questionÃrios e entrevistas com a populaÃÃo local, empreendedores, turistas e visitantes sendo realizada em dois momentos distintos, primeiramente em bibliotecas e ÃrgÃos pÃblicos e em seguida no prÃprio local. A partir das entrevistas e questionÃrios foi possÃvel conhecer melhor a opiniÃo dos turistas, moradores e empreendedores acerca do turismo realizado na regiÃo, opiniÃes estas muitas vezes contraditÃrias, e compreender as transformaÃÃes socioambientais ali geradas, propondo-se alternativas para a realizaÃÃo de um turismo sustentÃvel, como por exemplo, o planejamento integrado e participativo da atividade turÃstica naquele litoral.

The aim of the present thesis is to identify and describe spatial, seasonal, and multidecadal variations, by using historical data, and local ecological patterns in the fish fauna of the Cananéia-Iguape Estuary (ECI) in relation to ecological factors and/or factors derived from the exogenous discharge of the Ribeira de Iguape River (RI) flowing through the Valo Grande artificial channel. It was demonstrated the relation of hydrological attributes, seasonality, and spatiality with the beta diversity of the soft bottom infralitoral fish assemblage in local scale (i.e. within an ECI estuarine sector, the Trapandé Bay) with a seasonally and spatially stratified sampling design and monthly sampling (July/2009 June/2010) using otter-trawl net. Two patterns were identified: (I) fish species richness and abundance were higher and seasonally persistent in inner (environmentally favorable habitat) than in outer sector of bay; and (II) a variability of this fish faunas spatial structure induced by the effect of the interaction among depth, water temperature, and seasonal rhythms of fish populations. ECI hold 246 fish species between 1962 and 2010 and 214 species between 1993 and 2010. Mathematic extrapolators estimated > 173 species in the south axis of ECI. In rainy season, fish species richness and abundance in south axis increase with increasing (I) massive immigration of individuals from north axis of ECI due to the highest RI discharge and lowest salinity; (II) massive recruitments and reproductive aggregations and activities, which are coupled with the peak of primary and secondary productivity in ECI. It is proposed the existence of a metacommunity ruled by mass effect between assemblage of Trapandé bay and regional pool of marine populations. The degradation of ECIs estuarine conditions due to RI inflow limited multispecific dispersion among resident estuarine and marine species. This resulted in a spatial gradient of generalized loss in abundance, richness, and function in the fish fauna structure that strongly follow the spatial gradient of impact. The signal of this anthropogenic effect was enough high to be revealed even under interference from other sources of environmental, spatial, and temporal variability. The reduction of RI inflow to ECI in order to recover its ecological estuarine conditions is a governmental authorities correct decision to also recover the fish dispersion and, thus, the ecosystem functionality of fish fauna

The Cananéia-Iguape System suffered important changes due to the opening of Valo Grande Channel, which connect this System to the Ribeira de Iguape River. The mining activities in the Ribeira Valley affected the river basin, reaching this System through Valo Grande. The main goal of this study was to evaluate the availability of Cu, Pb and Zn in the Cananéia-Iguape System, based on the content associated with the main components of the sediments. In order to estimate chemical contamination, the content of these elements was compared to Canadians limits (ISQG and PEL), to the content of these metals in the region in period preceding to the intense mining activity and to the background values (shale average composition). The results for Cu and Zn indicated that in case of remobilization, they possibly would not represent a hazard to the biotic communities. However, the available content for Pb exceeded the comparative values at various stations, suggesting attention regarding its bioavailability. In general, the region that favored the most the accumulation of metals was Mar Pequeno, possibly due to oceanographic conditions. Data regarding geochemistry and geochronology of cores enable the observation of the insertion the Pb anthropogenic in the System during the mining period.

Esse estudo teve como objetivo avaliar os sedimentos do Complexo Estuarino Lagunar Cananéia-Iguape-Peruíbe (CIP) através da utilização de análises químicas e ecotóxicologicas, com a finalidade de determinar se os metais dos sedimentos estavam biodisponíveis para organismos bentônicos. As diferentes ferramentas mostraram que o estuário possui mudanças geradas pela contaminação por metais, provenientes de atividades de mineração situadas no alto do Rio Ribeira de Iguape. A toxicidade foi atribuída principalmente aos metais e a amônia, sugerindo que a combinação de fatores naturais e antrópicos são capazes de produzir risco ecológico. Esse estudo evidencia também que ao longo dos estuários, as áreas de deposição mudam acompanhando o deslocamento da zona máxima de turbidez, que está associada com entradas de água doce, regime de chuvas e consequentemente a sazonalidade. Dessa forma, os processos oceanográficos devem ser considerados importantes fatores que influenciam a acumulação de contaminantes em áreas estuarinas. O teste de bioacumulação mostra que esses contaminantes estão biodisponíveis aos organismos, especialmente em áreas mais contaminadas e, portanto, podem ser transferidos ao longo da cadeia alimentar, com implicações nos processos ecológicos e na saúde humana.

The complex exchange of fluvial, subsurface and seawater within a coastal area directly affects global biogeochemical cycles and the application of isotopic tracers, mainly natural radionuclides from U and Th series, is a powerful tool to track sources and sinks of trace elements and nutrients to this systems. The unique Ra signature applied to quantify the contribution of such fluxes is acquired within the subterranean estuary, a mixing zone between fresh groundwater and seawater in coastal aquifers. In the U and Th natural radioactive decay series there are four radium isotopes: 223Ra (t1/2 = 11.4 d), 224Ra (t1/2 = 3.7 d), 228Ra (t1/2 = 5.7 y) and 226Ra (t1/2 = 1,600 y). Their wide range in half-lives corresponds well with the duration of many coastal processes. All these Ra isotopes derive from decay of Th parents, which are tightly bound to particles. Because Ra is mobilized in the marine environment, sediments provide a continuous source of Ra isotopes to estuarine waters at rates set by its decay constants. The Th isotope activities in the sediments and the distribution coefficient of Ra between the sediments and water determine the potential input of each Ra isotope to the water. Because 228Ra is regenerated much faster than 226Ra, estuaries with high 228Ra/ 226Ra activity ratios in the water must have a high degree of exchange with sediments on the sea bed or with groundwater draining nearby. This information is useful to elucidate the contribution of estuarine systems to the exchange of trace elements, N, P and C in the mixing zone. The combined source functions for Ra in a coastal area include riverine particulates/ dissolved input, oceanic dissolved concentrations, input from sediments and groundwater. The relative significance of each of these sources is usually a function of the site-specific hydrogeology and where the samples are taken relative to the salinity gradient (extent of freshwater/saltwater mixing). Thus, the Ra isotopes provide fundamental information on the interaction of sediments, groundwater and estuarine waters. In this project, the distribution of natural Ra isotopes was studied in surface, groundwater and estuarine water samples collected from dry and wet seasons (2009 2010) campaigns performed in Ribeira Valley, Southern São Paulo State. The inventory allowed the application of Ra isotopes as tracers of fluvial and groundwater discharges to the Cananéia-Iguape estuarine complex. The exchange of groundwater/ surface water in Ribeira do Iguape River basin and related fluxes of several constituents for the Cananéia-Iguape estuarine complex mass balance is still not very well known. The results obtained in this research work evidenced that there is a prevalence of 228Ra isotope in all the set of samples analyzed. However, the activity concentrations of Ra isotopes determined from Higher Ribeira Valley through the Southern Coastal Plain of São Paulo are representative of natural background levels, showing low or minimal human intervention. In the set of samples collected along Ribeira do Iguape River, Cananéia and Iguape outlets, the higher concentrations of Ra were observed in bottom waters, indicating the diffusion of 228Ra from sediments recently deposited as a potential source of the increased concentrations of this isotope when compared with others. The activity concentrations of the short-lived Ra isotopes were negligible, lower than the limit of the detection. Fluxes of Ra for Cananéia outlet are strongly influenced by tidal oscillations, which modulate the increase and decrease of Ra concentrations in response of the respective increase and decrease of waters salinity. In Iguape outlet and in hydrochemical stations performed along Ribeira do Iguape River it was observed a linear relationship between the amount of suspended matter and the increase of 228Ra activity concentration. When we evaluate qualitatively the differences in behavior of both long-lived Ra isotopes, the concentrations of 226Ra have not shown similar distribution to 228Ra. This demonstrates negligible contribution from advective porewaters and groundwater to the studied scenario. Dominant fluxes of trace-elements, radionuclides and nutrients have their main sources centered on fluvial, sediments and suspended matter compartiments.

Resumo: Com o objetivo de estudar as associações entre pequenos mamíferos da Mata Atlântica e artrópodes ectoparasitas, este estudo foi desenvolvido na Estação Ecológica de Juréia-Itatins - SP, no período de março de 1989 a fevereiro de 1990. Foram estudados seis hospedeiros, três roedores e três marsupiais e suas relações com 12 espécies de invertebrados, quatro insetos, incluindo uma espécie causadora de miíase e uma associação mutualística, e oito acarinos. A intensidade parasitária, a relação com a época do ano e a pluviosidade foram também correlacionados com a abundância tanto dos hospedeiros quanto dos ectoparasitas. O hospedeiro que apresentou maior freqüência de captura foi roedor Oryzomys intermedius, e o ectoparasita com maior freqüência foi o ácaro Gigantolaelaps gilmorei, que prevalece naquele hospedeiro. O díptero Metacuterebra apicalis provocou miíases em hospedeiros de classes taxonômicas diferentes, o roedor Oryzomys intermedius e o marsupial Metachirus nudicaudatus. O mesmo ocorreu na associação mutualística entre o coleóptero Amblyopinus sp. e seus dois hospedeiros, o roedor Trinomys iheringi e o marsupial Philander opossum
Abstract: In order to study the associations between small marnrnals living in the Atlantic Forest and their parasitic arthropods, a study was undertaken at the "Juréia-Itatins" Ecological Reservation, located in São Paulo State, from march 1989 to february 1990. Six host species were studied: three of rodents and three of marsupiaIs. Twelve species of parasitic arthropods were collected: four of insects, and eight of Acari. The intensity of parasitism , the period of the year and the pluviosity were correlated with the abundances ofthe ectoparasites and their hosts. The most abundant host was Oryzomys intermedius, and the most common parasite was the mite Gigantolaelaps gilmorei. The fly Metacuterebra apicalis caused myiasis in two different hosts: O'yzomys intermedius (Rodentia) and Metachirus nudicaudatus (Marsupialia). The same phenomenon ocorred with the mutualistic association between the staphylinid beetle Amblyopinus sp. and it hosts Trinomys iheringi (Rodentia) and Philander opossum (Marsupialia)

The objective of this work is to evaluate the relative importance of waves and longshore drift currents in the migration process of the Icapara and Ribeira de Iguape inlets. The wave climate was obtained from the Wavewatch III model. The system migration rates were estimated through a Landsat image time series. Through the application of the numerical model Delft3D, the waves were propagated to shallow waters, near of Ilha Comprida\'s and Juréia\'s Beach sand spits. Thus, the characteristics of the waves extracted from the model allowed the estimation of longshore drift trends in these segments. The extraction of the coastline of images between June 16th 1985, and July 7th 2016, showed the continuity of Ilha Comprida Island and Juréia Beach lateral accretion process, with a total variation of 852 and 669 m respectively, which occurred at annual rates of 27 and 21 m.year-1. During this period, the growth of these features promoted the displacement of the mouths of Icapara, for NE, and the Ribeira de Iguape, for SW. The transport components exhibited a resultant NE direction at both points, with higher values at Juréia Beach. The results show the relationship between the longshore drift and the inlets lateral migration, indicating its relative importance as a controlling process of the local morphodynamics.

Toponymy that is, the study of place names studies the proper nouns that assume the role of naming land forms or cultural anthropological features of a given locality, composing the geographical nomenclature of that place. In the case of this research, the studied toponymy was extracted from Iguape, a coastal municipality in the south of São Paulo State. The systematic study of the names of streets, avenues, squares, rivers, creeks, hills, etc. within the municipality constitutes a study of microtoponymy. As such, this work informs the project Atlas Toponímico do Estado de São Paulo, which in turn is a part of a larger project: the development of the Atlas Toponímico do Brasil. The methodology used in both projects draws from Dauzat\'s \"area method\" and George Stewart\'s classification of names, adapted to the Brazilian context by University of São Paulo\'s Prof. Dr. Maria Vicentina de Paula do Amaral Dick, who elaborated a taxionomy composed of 27 taxa for the classification of the toponyms. Through linguistic-semantic research and the etymological origin of the 412 term-occurrences found in Iguape, we have managed to infer namers\' intentionality and motivation. We have verified that the largest share of them consists of numerotoponyms and that all the ethnolinguistic layers that compose Brazilian Portuguese are represented in Iguape\'s toponymy. Toponyms of Portuguese origin, centralized in the downtown area, reveal the intention of honoring important people from the municipality, which indicates the prevalence of anthropotoponyms and axiotoponyms. The lexicon of Brazilian origin, spread throughout the other neighborhoods, register the presence of exuberant nature, expressed by semes linked to water, vegetation, animals and land relief, among other. The contribution of the African lexicon is restricted to only one toponym, which keeps the reminiscences and the history of slavery in Brazil. In other words, toponyms in Iguape reflect the cross-influence of humans (either white, black or indigenous) and the environment (either physical or cultural), permeated by language.

The subject of this work was the coastal district of Iguape located in the city of Aquiraz, east coast of Ceará, 38 km from Fortaleza. In recent years, there has been a change in tourism demand in that region and increased investment by both the public and private capital and international levels. Tourism is an economic activity that transforms space and reorganizes the territories and at the same time, generates social and environmental impacts to the cities where it develops. Thus, this study sought to understand the social and environmental changes of tourism on the coast of Iguape, characterizing their social and environmental conditions, and propose measures to achieve sustainable tourism in the region. For a better understanding of the environmental changes of the Iguape coastline, it was divided into: Presídio´s beach, Iguape´s beach and Barro Preto´s beach, because they are most relevant in terms of tourism. Throughout this study were used concepts such as tourism, tourist attraction, tourist offer, tourist services, sustainable tourism, sustainable development, environment, landscape and environmental perception. The research was accomplished through reference books, observations, field surveys, questionnaires and interviews with local people, entrepreneurs, tourists and visitors being held at two different times, first in libraries, public agencys and then on the spot . From the interviews and questionnaires it was possible to better understand the view of tourists, residents and entrepreneurs on tourism held in the region, these often contradictory opinions, and understand the social and environmental transformations generated there by offering up alternatives to the achievement of sustainable tourism, like a global and participatory planning of tourism at the coast.
O objeto de estudo desse presente trabalho foi o litoral do distrito de Iguape localizado no município de Aquiraz, litoral leste do Estado do Ceará, a 38 km de Fortaleza. Nos últimos anos, tem-se observado uma mudança na demanda turística daquela região e um aumento dos investimentos tanto por parte do poder público como do capital privado nacional e internacional. O turismo é uma atividade econômica que transforma espaços e reorganiza territórios e, ao mesmo tempo, gera impactos socioambientais para as localidades onde se desenvolve. Desta forma, o presente trabalho buscou compreender as transformações socioambientais geradas pelo turismo no litoral do Iguape, caracterizando suas condições socioambientais e propondo medidas para a realização de um turismo sustentável naquela região. Para uma melhor compreensão destas transformações socioambientais o litoral do Iguape foi dividido em: praia do Presídio, praia do Iguape e praia de Barro Preto, por serem as praias de maior relevância do ponto de vista do turismo. Ao longo da pesquisa foram utilizados conceitos como: turismo, atrativo turístico, oferta turística, serviços turísticos, turismo sustentável, desenvolvimento sustentável, meio ambiente, paisagem e percepção ambiental. A pesquisa foi efetivada através de consultas bibliográficas, observações diretas, levantamentos de campo, aplicação de questionários e entrevistas com a população local, empreendedores, turistas e visitantes sendo realizada em dois momentos distintos, primeiramente em bibliotecas e órgãos públicos e em seguida no próprio local. A partir das entrevistas e questionários foi possível conhecer melhor a opinião dos turistas, moradores e empreendedores acerca do turismo realizado na região, opiniões estas muitas vezes contraditórias, e compreender as transformações socioambientais ali geradas, propondo-se alternativas para a realização de um turismo sustentável, como por exemplo, o planejamento integrado e participativo da atividade turística naquele litoral.
IZOTON, R. "Identidade e territorialidade quilombola na comunidade de Alto Iguape Guarapari Espírito Santo." Universidade Federal do Espírito Santo, 2016. http://repositorio.ufes.br/handle/10/9880.
O presente trabalho trata da identidade e da territorialidade na comunidade quilombola de Alto Iguape, localizada na região outrora conhecida como Goiabas, no município de Guarapari (ES), que recebeu a Certidão de Autodefinição como Remanescente de Quilombo no ano de 2012. Considero que Alto Iguape é uma comunidade quilombola translocal, pois seus membros não residem somente nas Goiabas, mas também em outras localidades da área urbana de Guarapari e em outros municípios da Grande Vitória. Mesmo assim, os sujeitos que moram fora das Goiabas possuem forte vinculação com seus parentes do interior e sentem-se parte da mesma comunidade. Após dois anos de pesquisa etnográfica realizada nas Goiabas e em Jabaraí, bairro da área urbana do município onde reside o maior número de quilombolas fora das Goiabas, constatei que o processo de constituição da sua identidade quilombola ocorreu paralelamente ao seu processo de reconhecimento e certificação pela Fundação Cultural Palmares, visto que anteriormente os seus membros não se identificavam como quilombolas. Participaram de ambos os processos, em maior ou menor grau, além dos próprios quilombolas, diversos atores externos, na maioria agências do poder público municipal, estadual e federal, bem como integrantes da comunidade quilombola de Monte Alegre, do município capixaba de Cachoeiro de Itapemirim. A identidade quilombola passou a ser reivindicada inicialmente no núcleo de Jabaraí, devido ao maior contato desse núcleo com as referidas agências, e só depois foi apropriada de diferentes maneiras pelos membros do núcleo das Goiabas: alguns negam tal identificação; outros a encaram como algo adjudicado; e outros, ainda, a apropriam autonomamente. Na constituição dessa identidade, os de Alto Iguape mobilizam os mesmos elementos que utilizam para a construção da sua territorialidade, que são as suas relações de parentesco, as suas atividades econômicas e relações de trabalho, as suas relações com o meio ambiente e as suas práticas espirituais e religiosas. Por isso, é possível afirmar que ambos os processos são relacionais, já que são baseados nesses quatro níveis de relações sociais. Palavras chave: Comunidades quilombolas. Identidade. Territorialidade.

Resumo: Os cordões litorâneos da planície costeira da Jureia incluem-se entre os mais bem preservados alinhamentos de cordões do litoral sul do estado de São Paulo, porém, são pouco estudados sob os aspectos sedimentológico e estratigráfico. A meta deste estudo é reconstruir no tempo e espaço os eventos de formação dos alinhamentos de cordões litorâneos e feições associadas, inferindo possíveis controles exercidos pelo nível relativo do mar (NRM), clima e dinâmica sedimentar costeira. Através da análise de fotografias aéreas e imagens de satélite, foram reconhecidos quatro feixes de cordões litorâneos e quatro pontais recurvados. O feixe 1 é formado por cordões curvilíneos, enquanto que os feixes 2, 3 e 4 são constituídos por alinhamentos mais retilíneos e desenvolvem-se sincronicamente à formação de pontais recurvados. Estes, em planta, diferem-se por geometria côncava na forma de cordões recurvados, que mostram inversões cíclicas no padrão de transporte sedimentar por deriva litorânea, ora para NE e ora para SO. Em seção GPR observa-se que internamente, os feixes de cordões são formados por refletores com configuração sigmoide de amplitude alta a moderada, que estendem-se lateralmente por centenas de metros com mergulho suave para o mar. Esses refletores incluem fácies de areia média com estratificação cruzada acanalada sobreposta por fácies de areia média a fina com estratificação plano-paralela.

Abstract: The strandplain in Jureia comprises the best preserved ridges in the southern São Paulo state. However, they have been poorly studied from the sedimentologic and stratigraphic aspect. This study aims to reconstruct the events of ridge alignments development of, in time and space, inferring possible controls related to relative sea level (RSL), climate and coastal sedimentary dynamics. The analysis of aerial photographs and satellite images enabled the identification of four ridge sets and four recurved spits. Ridge set 1 is composed by curved ridges in the inner portion of the coastal plain, while ridge sets 2, 3 and 4 comprise plan-parallel ridges which were developed synchronically to recurved spits. The spits are distinctive for the concave geometry, which shows cyclic inversions in the pattern of sedimentary transport through longitudinal drift currents, alternating the main direction between NE and SO. In GPR sections it can be observed that the ridges are internally formed by sigmoidal reflectors, with high to moderate amplitude, which extend for hundreds of meters with smooth seaward dip. These reflectors comprise sedimentary facies of cross stratified medium sand overlaid by plan-parallel medium and fine sand. Ophiomorpha nodosa burrows, attributed to the arthropod Callichirus major, are present throughout the layers but become rare towards the top. These deposits have been interpreted as shoreface facies association in gradual contact with the foreshore facies associ... (Complete abstract click electronic access below)

Resumo: O Vale do Ribeira possui uma das áreas de beleza natural mais exuberante do Brasil. Entre seus parques e reservas naturais de mata atlântica se encontra uma imensa biodiversidade entre fauna e flora. O Vale do Ribeira possui diversas Unidades de Conservação (UCs), uma dessas é o Parque Estadual da Ilha do Cardoso (PEIC). O foco deste trabalho será a comunidade do Marujá, que reside no PEIC. Esta comunidade tem sido relativamente bem-sucedida nas suas tentativas com o estado em cumprir seus objetivos de conservação e preservação ambiental. Apesar deste sucesso, constata-se que os moradores têm muito receio de serem retirados do PEIC. Aliado a isto, os moradores têm ainda muitas dúvidas sobre como se organizar para atingir o seu objetivo de permanência no PEIC. Diante dessa problemática, o problema central que este trabalho procurará responder é como auxiliar a comunidade do Marujá a se reorganizar para que eles alcancem seu objetivo de permanência no PEIC? Considera-se que este tipo de problemática seja tratável mediante a utilização do processo sóciotécnico MACBETH de apoio multicritério à decisão, devido esta ser uma abordagem humanista, interativa e construtivista. Pois esta metodologia leva em consideração tanto os aspectos sociais quanto técnicos em qualquer decisão que envolva múltiplos critérios. O objetivo central desta dissertação é aplicar a abordagem MCDA, por meio do processo sóciotécnico MACBETH, a fim de auxiliar a comunidade do Marujá a se reorganizar e reestruturar, visando a sua permanência no PEIC. Começa-se esta dissertação por uma breve introdução ao tema, levantando a problemática, a hipótese, justificativa e objetivo central do trabalho. No segundo capítulo faz-se uma contextualização histórica da comunidade do Marujá, abordando aspectos físicos, sociais e econômicos da região. No terceiro capítulo faz-se uma revisão de literatura do processo sóciotécnico MACBETH de apoio multicritério à decisão, que será o instrumento metodológico deste trabalho. O quarto capítulo apresenta o processo sóciotécnico MACBETH implementado na comunidade do Marujá, demonstrando todas as fases do processo. Por último têm-se algumas considerações finais sobre os resultados deste processo. Conclui-se que a utilização deste processo auxiliou a comunidade a organizar melhor suas ideias, definirem concretamente seus objetivos fundamentais nas diversas áreas (saúde, educação, transporte, energia) e lutarem pelo seu objetivo estratégico, a permanência da comunidade dentro do PEIC
Abstract: The Ribeira Valley boasts one of the most exuberant natural beauty areas of Brazil. Among its parks and natural reserves of the Atlantic Forest is an immense biodiversity of fauna and flora. The Ribeira Valley has several protected areas (PAs), one of them is Parque Estadual da Ilha do Cardoso (PEIC). The focus of this work will be the community of the Marujá, which resides in PEIC. This community has been relatively successful in their attempts to comply with state goals of environmental conservation and preservation. Despite this success, it appears that residents have much fear of being removed from PEIC. Allied to this, the residents still have many questions about how to organize themselves in order to achieve their goal of staying in PEIC. Faced with this problem, will it be possible to help the community Marujá to reorganize itself so that they achieve their goal of staying in PEIC? It is considered that this type of problem is treatable through the use of the MACBETH sociotechnical process of multicriteria decision aid, because this is a humanistic, interactive and constructivist approach. Because this methodology takes into account both the social and technical aspects in any decision involving multiple criteria. The central objective of this dissertation is to apply the MCDA approach through the MACBETH sociotechnical process, to assist the community of Marujá to reorganize and restructure itself in order to stay in their PEIC. This dissertation begins with a brief introduction to the subject, raising the question, hypothesis, justification and central objective of the work. The second chapter is a historical overview of the community of Marujá, addressing physical, social and economic developments in the region. The third chapter is a literature review of the MACBETH sociotechnical process multicriteria decision aid, which will be the methodological instrument of this work. The fourth chapter presents the MACBETH sociotechnical process implemented in the community of Marujá, demonstrating all stages of the process. Finally there are a few final considerations about the results of this process. It is concluded that the use this process helped the community to better organize their ideas, ultimately establish their fundamental objectives in various areas (health, education, transportation, energy) and fight for their strategic objective, namely keep leaving in the community PEIC

During several decades the Alto Vale of Ribeira region (SP-PR) was under influence of lead mining activities, refined and processed in the mines of the region. Since 1996, all such activities ceased, however, leaving behind a huge amount of environmental liabilities. This study aimed to investigate the presence and concentration levels of metals cadmium (Cd) and lead (Pb) and metalloid arsenic (As) in the water, sediment and biota (fish blood) in the aquatic systems of Ribeira do Iguape River and its tributaries, for an environmental assessment and monitoring of the region. The sampling collection occurred in 8 sites and fish samples were caught by fishing nets and blood sampling was done in the site. The determination of these elements was carried out by atomic absorption spectrometry with graphite furnace electro thermal heating (GF AAS). This study also assessed the occurrence of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cs, Hf, Rb, Sb, Sc, Se, Ta, Th, U, Zn) and rare earth elements (La, Ce, Eu, Nd, Sm, Lu, Tb and Yb) by Neutron Activation Analysis (NAA). Validation of both methodologies, regarding precision and accuracy, was done by reference material analyses. The results obtained for As, Cd and Pb in the sediment were compared to the Canadian Council of Ministers of the Environment (CCME), TEL (Threshold Effect Level) e PEL (Probable Effect Level) adopted by CETESB and CONAMA 454/2012 Resolution. The results for As, Cd and Pb in water samples were below the QL of the analytical technique used, indicating that these elements are in concentration levels that do not affect the water quality standard established by CONAMA 357/2005. On the other hand, the concentration values for these elements in fish blood and sediment samples showed a strong contamination tendency for Cd and Pb most of the sampling points assessed. The highest Cd concentration in fish blood was 24.3 μg L-1, at site 2. For Pb, the highest concentration value was 118 μg L-1, at site 5. The concentration values for As were lower than QL (30 μg L-1) of the method for all fish blood analyzed. The sediment of site 5 presented values of 72.1 mg kg-1 for As and 474 mg kg-1 for Pb and both were well above the PEL limits, being classified as Bad quality. A strong correlation between metals in sediments and blood fish samples was verified. The results obtained by INAA in the sediment samples were assessed by geochemical tools, Enrichment Factor (EF) and Geoaccumulation Index (Igeo), to evaluate the extent of metal pollution in sediments. Again site 5 presented the highest EF and IGeo values and it was considered highly polluted for As and polluted for Sb and Zn. Site 7, was considered moderately polluted for As, Br and Sb. Although all mining operations have long ceased the deleterious effects on the environment are still present.

Resumo: O ecoturismo tem sido apontado como uma das soluções mais apropriadas para solucionar o conflito sócio-ambiental e alavancar o desenvolvimento no Vale do Ribeira, o que se deve ao caráter potencialmente sustentável dessa modalidade turística e, portanto, compatível com o uso legal de um território protegido, em quase toda a sua extensão, por unidades de conservação. Por outro lado, a inobservância do ideal do ecoturismo tem levado a adoção de sistemas de certificação para assegurar a sua sustentabilidade. Por meio da análise compreensiva, desenvolvida neste trabalho, produzimos uma leitura acerca do ecoturismo como solução ao conflito sócio-ambiental no Vale do Ribeira que revela não somente as estratégias de dominação ocultas no uso de instrumentos destinados ao desenvolvimento regional, mas, sobretudo, a incompatibilidade entre a idéia de desenvolvimento no mundo contemporâneo e o ideal do ecoturismo, enfatizando a importância de restituir ao lugar, definido pelo Bairro da Serra ¿ Iporanga, SP, o papel de agente ativo no processo de desenvolvimento diante das pressões verticais da globalização em que o turismo, regionalmente, tem operado como um catalisador
Abstract: Ecotourism has been pointed out as a suitable solution to promote development in Vale do Ribeira due to its potential sustainability and compatibility with the legal use of a territory which is occupied by protected areas over almost its total extension. On the other hand, negligence with the ecotourism ideal has led to the use of certification as a mean to assure ecotourim sustainability. By means of the comprehensive analisys developed in this work, we offer an approach to the idea of taking ecotourism as a solution to the environmental and social conflict in Vale do Ribeira which reveals social domination strategies, as well as the ecotourism ideal incompatibility to the development idea in the contemporary world. This emphasizes the importance of local empowerment of Bairro da Serra ¿ Iporanga, SP, as a mean to improve its role as an active agent in the development process under the vertical globalization pressure in which tourism has played a catalyst part regionally

Past and current environment conditions drive changes to mangrove structure and distribuition along the coast. This paper aims to caracterize mangrove forest dynamic tendencies at Cananeia-Iguape System. Digital image processing and region morphodynamics support the present study. Cananeia-Iguape System is located at the South of São Paulo State (Brazil), latitude 25oS. A colored composition (RGB TM4/TM3/TM2) of Landsat TM digital images (WRS 220/77D) from different dates (14/09/86 and 02/09/99) were processed with ILWIS SIG (Integrated Land and Water Information System). Mangrove forest structure and topographic sampling spots were chosen given the results of supervised classification and given its sedimentary morphodynamic deposition, following Tessler (1982) and Tessler & Furtado (1983). Mangrove forest structure study is based on Cintrón & Schaeffer-Novelli (1984). Single linkage cluster analysis has confirmed the results obtained from the mangrove forest structure study. Region sedimentary dynamics and topographic factors drive mangrove colonization by particular species on deposition shores.

The Restinga forests are located along the Brazilian coast. These forests, recently developed on sediments deposited during Quaternary sea-level changes, have significant biodiversity. Located in Iguape, State of Sao Paulo, Brazil, the Una Plain is characterized by Holocene beach ridges and forest types that reflect different conditions of the sediment granulometry, soil fertility and water level imposed by the morphology of the ridges. Based on environmental variations, the study aimed to identify geobotanical units through digital processing of ASTER images. After the interpretation of index-images resulting from the ratio of the NIR/SWIR bands, eight geobotanically heterogeneous areas were selected. In these areas sediment and soil were sampled, water level was measured, digital photographs of the canopy was took from the ground level and floristic inventory was done. To enhance the vegetation spectral behavior and albedo for the delineation of the geobotany units, we followed the systemic approach in the digital images processing. The Jaccard index, diversity indices and Cluster analysis were calculated to evaluate the similarity of the areas using field data and the pixels digital numbers. Using Pearson correlation, the granulometry sediments, soil fertility, water level and leaf area data were linked to remote sensing data. Four geobotanical units were established in the plain of Una considering these physical and biotic parameters as texture, soil fertility, water level, vegetation height, relative density, species and families richness and floristic similarity. The colored compositions obtained from digital image processing were able to discern these units. The correlation (\'rô\' ^) found between the pixel data and the physical parameters analyzed allow to state that soil fertility and, mainly, granulometry are important parameters in the separability of the proposed units by remote sensing. According to the results obtained, the Geobotany by Remote Sensing was capable to indicate different forest covers and, indirectly, the grain size of the underlying sediments. However, for the definition of geobotanical units it is necessary in situ data collection, analysis of the parameters that influence the vegetation and the combined interpretation of the images derived from digital processing, where the albedo is essential information. Considering the above presented, this research contributes to understanding the coastal Atlantic Forest.

A região do médio e baixo vale do Rio Ribeira de Iguape, no sul do estado de São Paulo e nordeste do estado do Paraná, apresenta fortes feições morfotectônicas regionais expressas na paisagem através de cristas alinhadas e segmentos retilíneos de drenagem em torno da direção NW-SE, apesar do forte controle estrutural imposto pelas estruturas relacionadas às rochas pré-cambrianas, direcionadas NE-SW. Essas feições direcionadas NW-SE são relacionadas ao Lineamento Guapiara, constituído por um expressivo enxame de diques básicos mesozoicos e combinado a um intenso fraturamento que afeta todo o substrato rochoso. A região foi palco também da tectônica rúptil formadora dos riftes cenozoicos. O principal objetivo deste trabalho é o reconhecimento de feições estruturais associadas aos traços do Lineamento Guapiara e sua caracterização com ênfase nas falhas que possam estar associadas ao controle da evolução da paisagem local e, com isso, contribuir com o entendimento da evolução neotectônica da região. As análises e integração de dados dos mapas de lineamentos de drenagens e de relevo, de compartimentação geomorfológica e mapa geológico conduziram a seleção de áreas de interesse para os trabalhos de campo e coleta de dados estruturais. Estes foram organizados de acordo com o tipo de estrutura, classificação do sentido de movimento e unidades em que cada estrutura afeta, com o intuito de se obter uma cronologia relativa dos eventos tectônicos, bem como deduzir os eixos de paleotensões associados aos sucessivos eventos. Entre as feições estruturais reconhecidas, destaca-se a principal família de juntas NW-SE, associada ao evento responsável pelo fraturamento e preenchimento de magmas básicos no Mesozoico e formação dos enxames de diques. Falhas normais de direção NE-SW, associadas aos sedimentos cenozoicos estariam relacionadas ao evento paleógeno de origem das bacias cenozoicas na região, com o quadro de paleotensões indicando o eixo de maior esforço segundo a direção NE-SW e distensão NW-SE. Falhas sin-deposicionais da Formação Pariquera-Açu indicam a persistência deste regime de esforços na região até o Mioceno Médio. Falhas transcorrentes sinistrais deformam os sedimentos cenozoicos e apontam para pulso compressivo NNW-SSE a N-S, atuante a partir do Plioceno. O Conjunto de falhas normais NW-SE, que deforma a Formação Pariquera-Açu, associado a falhas transcorrentes destrais WNW-ESE a E-W, que deformam sedimentos do terraço aluvionar do Rio Ribeira de Iguape e são interpretados como decorrentes do quadro neotectônico regional. A reconstrução dos eixos de paleotensões para este evento indica o posicionamento do eixo de maior esforço segundo a direção NW-SE.
The region of the middle and lower Ribeira de Iguape River valley, in the south of São Paulo state and the northeast of the Paraná state, is characterized by strong regional morphothectonic features expressed in the landscape through aligned ridges and rectilinear drainage segments around the NW-SE direction, despite the strong structural control imposed by NE-SW structures related to Precambrian rocks. These NW-SE directed features are related to the Guapiara Lineament, constituted by an expressive swarm of Mesozoic basic dikes and combined with an intense fracturing that affects all the rocky substrate. The region was also submitted to the brittle tectonic event that originated the Cenozoic riftes. The main objective of this work is the recognition of structural features associated to the Guapiara Lineament traces and its characterization, with emphasis in the faults that may be associated to the control of the local landscape evolution and to contribute to the understanding of the neotectonic evolution of the region. Data analysis and integration of drainage and relief lineaments maps, geomorphological compartments and geological map conducted to the selection of areas of interest for fieldwork and structural data collection. Data were organized according to the type of structure, classification of the sense of movement and units in which each structure affects, in order to obtain a relative chronology of tectonic events and to deduce the paleostress axes associated to successive events. Among the recognized structural features, standouts the NW-SE joints set, associated to the event responsible for fracturing and filling of basic magmas in the Mesozoic and the formation of the dyke swarms. NE-SW normal faults, associated to the Cenozoic sediments are related to the Paleogene event of Cenozoic basins in the region, with a paleostress frame indicating the axe of maximum compressive stress striking NE-SW and a NW-SE extension. Sin-depositional faults to the Pariquera-Açu Formation point to the persistence of this tectonic regime in the region until the Midlle Miocene. Sinistral transcurrent faults deforming Cenozoic sediments indicate a NNW-SSE to N-S compressive pulse aging during the Pliocene. The set of NW-SE normal faults, which deforms the Cenozoic Pariquera-Açu Formation, as well as the set of WNW-ESE to E-W directed dextral transcurrent faults that deform sediments from the alluvial terrace of Ribeira de Iguape River are interpreted as resulting from the regional neotectonic regime. The reconstruction of paleostress axes for this event indicates a NW-SE axis of maximum compressive stress.

A bacia do Ribeira de Iguape e Litoral Sul (CBHU-RB), localizada em uma das poucas áreas ainda preservadas do Estado de São Paulo, apresenta características particulares, pois possui grande parcela de sua extensão em Áreas de Proteção Permanente(APPs), sendo seu bioma exclusivo de Mata Atlântica. Assim o presente trabalho realizou analises de aspectos físico, químicas e ecotoxicológicas em água e sedimento para avaliação de 4 pontos de coleta no Alto da Bacia do Ribeira de Iguape. Os parâmetros analisados em água foram; temperatura, pH, condutividade, oxigênio dissolvido, determinação de sólidos em suspensão e dissolvidos, fixos e difusos, Carbono Orgânico Total (T.O.C), Nitrogênio Orgânico Total (NOT), Demanda química de oxigênio (DQO), Demanda Bioquímica de Oxigênio (DBO 20,5). Já no sedimento foram avaliados os parâmetros porcentagem de matéria orgânica, granulometria, fósforo e nitrogênio total. Além de metais totais em água e sedimentos. Ainda, foram realizados testes ecotoxicológicos com microcrustáceo, Ceriodaphnia dúbia, amplamente utilizado em estudos de ecotoxicologia de água doce.Em relação às análises de metais nas amostras de água, foram encontrados valores acima do valor máximo permitido pela RESOLUÇÃO CONAMA 357/05, em todos os pontos de coleta para os metais Arsênio, Cádmio e Chumbo, assim como Manganês nos pontos 1, 2 e 4. Assim, também para as amostras de sedimento foram obtidos altos teores de Chumbo e Zinco em relação aos valores de referência para sedimento, conforme CONAMA 454/2012. Os valores encontrados para os elementos As, Cd, e Pb estiveram próximos aos limites de quantificação para as amostras de água que por sua vez são maiores que os valores da CONAMA. Já para o metal Mn pode ser explicado seu elevado teor devido à ocorrência natural. Os resultados da toxicidade aguda na água não mostraram efeito na mortalidade de microrganismos. No entanto, no sedimento, o ponto 3 apresentou toxicidade aguda e no ponto 2 toxicidade crónica. Através da avaliação das análises físicas, químicas e ecotoxicológicas observou-se que o ambiente encontra-se controlado em sua qualidade ambiental, sendo necessária uma devida atenção para que a região permaneça com características peculiares de área de preservação permanente mesmo com a crescente demanda turística.
The drought is the most limiting and severe abiotic stress for agricultural crops, because it triggers a number of physiological adaptations and anatomical modifications in the plants as an adaptive process in response to the water deficit and which regulates the reduction of water losses from the plant to the atmosphere. In order to know the effect of water stress on the anatomical and physiological characteristics of soybean, as well as the selectivity of herbicides, the present work had as objective to examine the morphological and enzymatic alterations of soybean cultivars: MG / BR 46 Conquista (conventional) and BRS Valiosa (transgenic) by means of response to different water management in the soil, in two stages of vegetative development. The plants were submitted to different soil water management, in the vegetative development stage V2 and V4. Stomatal conductance, foliar area, and leaf and stem anatomy measurements were performed. The antioxidant stress was measured by lipid peroxidation, H2O2 content, proline, superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX). The spraying of fomesafen at rate 250 g a.i ha-1 and chlorimuron-ethyl at rate 20 g a.i ha-1 in soybean plants under different water restrictions was also evaluated. BRS Valiosa RR has a better adaptive morphological and anatomical performance in response to a moderate water restriction up to (-0.07 MPa) when it occurs in the first weeks of plant development. SOD, CAT and APX activity of transgenic plants showed an intense increase in the V4 stage, while the conventional cultivar did not overcome the stress condition in this period. These responses appoint that BRS Valiosa (transgenic) has a late response, which increases survival at long periods of water scarcity. Drought reduces visual phytointoxication when sprayed with the herbicides fomesafen and chlorimuron-ethyl. It was found that the spraying of the herbicide fomesafen and chlorimuron-ethyl has a negative effect on rhizobia infection, as well as the water deficit drastically reduced the biological nitrogen fixation and the growth of the soybean plants. When soybean plants were submitted to a moderate drought condition (-0.07 MPa) the conventional cultivar had its development more affected compared to the transgenic cultivar. It was also evidenced that the transgenic cultivar showed to have a greater capacity to support the biological fixation of nitrogen when submitted to a condition of moderate drought (-0.07 MPa) in comparison to the conventional cultivar.

O objetivo desse trabalho é analisar os processos de organização sociopolítica que decorrem da regularização fundiária na comunidade Quilombola de Santiago do Iguape, no período de 2010 a 2013. A comunidade de Santiago do Iguape, lócus dessa pesquisa, traz, na sua trajetória política, toda uma história de luta e resistência para garantir a preservação do território quilombola e, ao mesmo tempo, luta por um desenvolvimento que respeite as especificidades enquanto comunidade tradicional. Atualmente, sofre ameaças no seu território, a exemplo da implantação de um grande empreendimento na Reserva Extrativista Federal da Baía do Iguape (RESEX), o Estaleiro Enseada do Paraguaçu, localizado no entorno da Baía do Iguape, mais precisamente no município de Maragogipe. Diante desse cenário, as comunidades tradicionais que vivem no entorno da Baía do Iguape vivenciam conflitos fundiários e territoriais, que são travados pelos interesses estabelecidos entre o Estado e o grande capital, em detrimentos dos direitos dos povos e comunidades tradicionais. O estudo é de caráter etnográfico, o que exigiu uma imersão na comunidade de Santiago do Iguape durante o período de dois meses, no qual observei a dinâmica da comunidade e registrei os relatos no diário de campo, interagi e entrevistei os (as) interlocutores (as), membros das organizações da comunidade e demais moradores e moradoras de Santiago do Iguape.
The aim of this study is to analyze the socio-political organization of processes arising from the land regularization in Quilombola community of Santiago do Iguape, from 2010 to 2013. The community Santiago do Iguape, locus of this research, brings in his political career, all a history of struggle and resistance to ensure the preservation of the quilombo territory and at the same time, the struggle for development that respects the specific characteristics as a traditional community. Currently, suffer threats in its territory, such as the deployment of a large enterprise in the Extractive Reserve Federal Bay of Iguape - (RESEX), the Shipyard Cove do Paraguaçu, located in the vicinity of Iguape Bay, more precisely in the city of Maragogipe. In this scenario, the traditional communities living around the Bay of Iguape, experience land and territorial disputes, which are caught by vested interests between the state and big business, to the detriment of the rights of peoples and traditional communities. The study is ethnographic, which required an immersion in Santiago community of Iguape during the period of two months, during which I observed the dynamics of the community and registered accounts in the diary, interacted and interviewed them (as) partners (as), members of community organizations and other residents and residents of Santiago do Iguape.

The general aim of this thesis is to understand the fish assemblages of headwater and small streams of Jurupará State Park, a protected area located in São Paulo State. Located among other four protected areas, the park functions as a connector and contributes to the conservation of the Atlantic Forest and Upper Juquiá River basin, located in the Ribeira de Iguape River basin. Ten stream reaches (3rd to 5th order) were sampled between June and December 2010. Ichthyofauna was collected with electrofishing equipment, while environmental variables were visually quantified during onsite surveys and with cartographic maps of the region. Local environmental variables consisted of coarse substrate, diversity of water velocity, proportion of mesohabitats (i.e., riffles, pools and runs), banks stability and shading. Regional environmental variables consisted of vegetation cover, catchment area, altitude and stream reach position according to sub-basin. Fish assemblages structure analyses according to environmental variables were divided into two chapters, presented as scientific papers. The first chapter analyzed two issues, (i) fish assemblages α and β components and (ii) patterns in species composition according to environmental variables. In order to approach the first issue, we used multiplicative partitioning of true diversities to calculate α and β components and compare them with expected values in a null model. The second issue was approached by reducing the number of environmental variables with PCA and using the most significant gradients as predictor variables in a db-RDA, followed by a species composition variation partitioning according to each significant variable. The α and β components observed were different from expected by chance and the variation in species composition was strongly related to environmental variables operating at different scales. The proportion of coarse substrate and bank stability contributed with 6% of species composition variation, while sub-basin contributed with 10%. Possibly, the low percentage of variation explained by the model can be justified by the scale of the environmental variables. If the structuring of fish assemblages follows the null metacommunity model predictions, then variables related to stream topology and species intrinsic characteristics are more likely to better explain the spatial organization of the fauna. In Chapter II, we used data of occurrence frequency, average abundance and biomass to identify rare and common species of the fish assemblages. Withal, we used linear multiple regression models to analyze the abundance of Isbrueckerichthys epakmos according to local environmental variables. The importance of this species relies on its classification as endemic in Ribeira de Iguape River basin and threatened, according to IUCN criterion. Five species were very abundant and widely distributed in the sampled reaches, including I. epakmos, whose distribution was strongly related to coarse substrate and proportion of riffles and runs. Eight rare species were identified, two of them being also endemic of Ribeira de Iguape River basin, Astyanax ribeirae e Neoplecostomus ribeirensis. The elevated taxonomic and functional diversity observed indicates that the studied streams still hold physical integrity to support the biota and, probably, local ecological processes, despite the presence of impoundments that support four small dams installed inside the park.
O objetivo geral desta dissertação é entender as assembleias de peixes dos riachos de cabeceiras e pequeno porte do Parque Estadual do Jurupará, uma unidade de conservação de proteção integral do estado de São Paulo. Localizado entre outras quatro áreas protegidas, o parque possui função conectora e contribui para a conservação da Mata Atlântica do estado, além de contribuir para a proteção da bacia do Alto Rio Juquiá, inserida na bacia hidrográfica do Rio Ribeira de Iguape. Dez trechos de riachos (3ª a 5ª ordem) foram amostrados entre junho e dezembro de 2010. A ictiofauna foi coletada com equipamento de pesca elétrica, enquanto variáveis ambientais foram mensuradas em campo e com bases cartográficas da região. As variáveis ambientais consideradas de atuação local foram substrato grosso, diversidade de velocidades, proporção de mesohábitats (i.e, corredeiras, poções e rápidos), estabilidade das margens e sombreamento. As variáveis ambientais de atuação regional foram vegetação no entorno, área à montante do trecho amostrado, altitude e posição do riacho de acordo com a sub-bacia hidrográfica. As análises da estrutura das assembleias ícticas em função das variáveis ambientais foram divididas em dois capítulos, apresentados na forma de artigos científicos. O primeiro capítulo tratou de duas questões, (i) as diversidades α e β das assembleias de peixes dos riachos e (ii) padrões na composição de espécies em função das variáveis ambientais. Para analisar a primeira questão, aplicamos a relação multiplicativa proposta por Whittaker, utilizando a diversidade equivalente de Shannon, para calcular os componentes α e β e comparamos os valores obtidos com o esperado em um modelo nulo. Para a segunda questão, reduzimos o número de variáveis ambientais com uma PCA e os eixos mais significativos foram utilizados como variáveis preditoras em uma db-RDA, seguida do particionamento da variação da composição de espécies de acordo com cada variável significativa. As diversidades α e β dos riachos foram diferentes do esperado ao acaso e a variação na composição de espécies esteve relacionada a variáveis ambientais que atuam em diferentes escalas. A proporção de substrato grosso no canal e a estabilidade das margens contribuíram com 6% na variação da composição de espécies, enquanto que a posição do riacho de acordo com a subbacia contribuiu com 10%. Possivelmente, a baixa porcentagem de variação explicada pelo modelo pode ser justificada pela escala das variáveis selecionadas. Se a estruturação das assembleias de peixes seguir as previsões do modelo nulo da teoria de metacomunidades, é provável que variáveis relacionadas à topologia da bacia hidrográfica e às características intrínsecas das espécies sejam mais eficientes em explicar a organização espacial da fauna. No segundo capítulo, utilizamos dados de frequência de ocorrência, abundância média de indivíduos e representatividade em massa para identificar as espécies raras e mais comuns das assembleias. Paralelamente, utilizamos modeloslineares de regressão múltipla para analisar a abundância de Isbrueckerichthys epakmos em função de variáveis ambientais locais. O interesse nessa espécie justifica-se por sua classificação como endêmica da bacia do Rio Ribeira de Iguape e ameaçada de extinção, segundo os critérios da IUCN. Cinco espécies foram muito abundantes e amplamente distribuídas nos riachos estudados, entre elas I. epakmos, cuja distribuição esteve fortemente relacionada à proporção de substrato grosso e poções e corredeiras. Oito espécies raras foram identificadas, sendo duas endêmicas da bacia do Rio Ribeira de Iguape, Astyanax ribeirae e Neoplecostomus ribeirensis. A elevada diversidade taxonômica e funcional observada indica que os riachos amostrados ainda apresentam integridade física capaz de sustentar a biota e, provavelmente, os processos ecológicos locais, apesar da presença dos represamentos no interior do parque que abastecem quatro pequenas centrais hidrelétricas.

This work presents results of the application of geophysical methods (electromagnetic and radiometric) in three fluvial sambaquis: i) Moraes; ii) Caraça and iii)Estreito. The joint interpretation of the geophysical and archaeological data allowed the recognition of important features in the characterization of these sites. The results suggest specific interpretations for each situation, for the sites are constituted by layers of anthropic and natural material, showing the necessity to create parameters of differentiation between them. Archaeological excavations had been carried out to verify the structures inferred from the geophysical interpretation. In this process, it was possible to identify some archaeological features that were not visible in surface although some geophysical features were explained by natural material in the soil. These information and archaeological data had indicated the distribution of the materials in the archaeological space, allowing, for example, to delimit the sites, to determine the thicknesses of the layers, to identify layers with shells and to locate lithic materials and hearths.

The water resources managing unit 11 (UGRHI-11) corresponds to Ribeira de Iguape r iver Drainage Basin and São Paulo State Southern Coast and small adjacent basins is located in south of São Paulo State. This unit presents great diversity of terrestrial and aquatic environments, big areas of dissected relief with high slopes and lowland and a sector consists of coastal plains, mangroves, marine and river terraces. It is a region sensible not only to biodiversity aspects but included to geomorphology process because it\'s an environment conducive to erosion and landslides processes. The goal of this search was develop possible scenarios of soil use and occupation based in the evolution during 24 years (1986 - 2010) and forecast scenarios to 2025, analyzing the growth or retraction of classes of soil use and occupation and considering in this temporal evolution the actions of terrain modifiers. In the first step of methodology was developed the maps of susceptibility to erosion and landslides with the use of RUSLE and Weight Linear Combination. In the next step by using unsupervised classification were prepared maps of soil use and occupation of UGRHI -11 relative to years 1986, 1999 and 2010. The methods of Titus y Narayanan, Pfeffer, Ramhstorf and Intergovernmental Panel on Climate Change model were processed in the ArcGIS 10 program with the goal of calculate the vulnerability of Complexo Estuarino -Lagunar de Cananéia-Iguape to a potential increase in sea level in 2025, 2050 and 2100. The maps of soil use and occupation of 1986, 1999 and 2010 allies to the maps of erosion and landslides were used in Markov Chain Analysis and Cellular Automata in the IDRISI Taiga to simulation of classes of soil use and occupation of UGRHI-11 in 2025. In the last step were evaluated the classes of soil use and occupation that will be affected by one possible high tide event in 2025. The conclusion is that the application of differents kinds of geotecnology tools was effective even integrating different jobs: mapping of susceptible areas to erosion and landslides; mapping of soil use and simulation of scenarios o f 2025; beyond the calculation of vulnerability to a potential increase in sea level in (2025, 2050 and 2100). It was possible to aggregate all these products and to elaborate the last product the quantification of areas of classes of soil use and occupation of Complexo Estuarino-Lagunar de Iguape-Cananéia, in 2025.

The estuarine-lagoon complex of Cananéia-Iguape has suffered several anthropic impacts since the opening of the Valo Grande artificial channel, which significantly altered the northern sector of the system with the increase of fluvial influence. The silting up of the region has been a recurrent problem, impacting fishing, tourism and navigation. This work aims to understand the dispersion of the terrigenous contribution in the region with numerical modeling and updated data, for better reproduction of the simulation in the estuary. The results of the model showed high concentrations of the biogeochemical components in the northern sector of the system and low tidal influence, causing high retention of these elements in the region. The southern sector showed low river influence and high marine influence, with expected values of dissolved silica and phosphate and inorganic suspended matter for a preserved estuarine system. The model showed a good behavior for the region, with good hydrodynamic and water quality results. It is emphasized the importance of continuous monitoring of the region and the use of a model to monitoring the geomorphological development and the biogeochemical alterations of the estuary to assist in preventive measures with the intention of minimizing the anthropic impact in the system.

Resumo: O objetivo do presente trabalho foi o de contribuir para a compreensão dos processos de transporte do chumbo e metais associados ao longo do rio Ribeira de Iguape, na região sudeste do estado de São Paulo. Além de dados da literatura, foram levados em conta informações resultantes de estudos de sedimentos coletados em estações pertencentes a distintos setores da bacia do rio Ribeira. Nas proximidades da cidade de Sete Barras foram ainda estudadas amostras de água, sólidos em suspensão e de sedimentos do rio, logo após a passagem de uma atípica frente de cheia que provocou a inundação das várzeas baixas e altas. Na planície aluvionar de Sete Barras foram também coletadas colunas de sedimentos em lagoas com o objetivo de verificar o aumento da concentração de metais ao longo do tempo. O comportamento das concentrações de chumbo entre as estações de coleta de sedimentos situadas em Itapeúnas e aquela situada a entrada do canal do Vaio Grande apresentaram-se com 347 ~g/g, em, para 90 ~g/g, respectivamente. Este comportamento foi associado ao efeito diluidor promovido, principalmente, pela contribuição dada pelos demais corpos d'água que afluem ao rio Ribeira entre estas duas estações de coleta. Determinou-se as razões isotópicas de chumbo em amostras de sedimentos de 10 estações de coleta distribuída desde a região logo a montante da cidade de Ribeira-SP até a do Mar Pequeno, no complexo Lagunar-Estuarino de Iguape e Cananéia, com o objetivo de compará-las com as determinações feitas por outros autores em galenas das jazidas do tipo Perau e Panelas do Vale do Ribeira e de jazidas mais jovens. Os resultados demonstraram que as razões isotópicas dos sedimentos sobrepuseram-se ao campo das galenas das jazidas do tipo Panelas, mostrando que as atividades de extração e de beneficiamento dos seus minérios foram as que mais contribuíram para a contaminação, por chumbo, dos sedimentos deste rio. Os estudos das amostras de água, sedimento e sólidos em suspensão coletadas na calha do rio Ribeira, e de coluna de sedimentos das lagoas marginais em Sete Barras, demonstraram que os metais são transportados, principalmente, pelos sólidos em suspensão na água. A similaridade entre as concentrações de metais, em especial do Pb, na amostra de sólidos em suspensão com a do meio da coluna de sedimento da lagoa Nova permitiu estimar a massa deste metal que é transportada anualmente, pelo rio Ribeira, em 151 toneladas adsorvidos em uma massa total de 840.000 toneladas de sólidos em suspensão. Esta massa de chumbo equivale a 6% da produção anual de chumbo metálico do Vale do Ribeira em meados da década de 80. As concentrações de metais das amostras de sedimentos do perfil das lagoas indicaram que as concentrações basais (background) de chumbo, zinco e cobre são respectivamente de 40, 116 e 44 ~g/g e são cerca de 2 vezes superiores às obtidas por outros autores. O método de determinação do nível basal dos metais mostrou-se eficiente, rápido e muito mais econômico que os adotados, tradicionalmente, em campanhas de prospecção geoquímicas, baseadas em um grande número de determinações de amostras de sedimentos
Abstract: The objective of the present study is to clear some aspects of the transport of Lead and associated metais by suspended particulate matter along the Ribeira de Iguape River, in the southeastern region of the state of São Paulo. Literature data were taken into account, as well as findings gathered trom studies of sediments collected in stations at different sectors of the Ribeira river basin. In addition, in the region surrounding the city of Sete Barras, samples of water, suspended solids and sediments of the river were taken for study immediately after an atypical flood front had passed, causing the flooding of high and low plains. In the alluvial plains of Sete Barras, columns of sediments were also collected in lagoons, in order to verify the increase of metais with time. The behavior of concentrations of lead ranged from 347 1-19/g, in Itapeúnas,SP, to 90 1-19/g, at the entrance of Vaio Grande Channel. This behavior has been related with the dilution effect, due mainly to the contribution of the suspended material of the other tributaries which flow into the Ribeira in the stretch between these two sampling stations. Isotopic ratios of lead were determined in sediments taken at 10 sampling stations distributed from the high valley of the Ribeira down to its mouth in the estuarine lagoons system of Iguape and Cananéia , and were compared to values obtained by other authors in galenas of mines of the Perau and Panelas do deposits types, and of younger ore deposits as well. Results showed similar isotopic rates for sediments and galenas of deposits of the Panelas type, showing that extractive and beneficiation activities of its ores were the ones that most contributed to the contamination by lead verified in sediments of this river. Studies with water samples, sediments and suspended solids taken in the channel of the Ribeira River, and with sediments columns, of the marginal lagoons in Sete Barras, proved that metais are transported mainly by the solids that are suspended in water. Concentrations of metais, especially lead, in samples of the solids suspended in river waters were similar to those found in the midle of the column of sediments taken at Lagoa Nova. Therefore, the mass of this metal transported yearly by the Ribeira River could be estimated as being of 151 tons adsorbed on 840.000 tons of suspended solids.This mass of lead equals 6% of the annual production of metallic lead in the Ribeira River valley in the 80's. Samples of the sediments profile of the lagoons, indicated as background concentrations of lead, zinc and copper respectively 33, 116 and 43 I-Ig/g. These values are two times the values found by other authors. The procedure used for the determination of background levels of metais has proved efficient, fast and by far more economic than the ones traditionally adopted in geochemical prospecting, which count on a great number of determinations in stream sediments samples

Based on the ecological, social and cultural interaction, this work has searched for the understanding of Manjuba fishing organization (Anchoviella lepidentostole) in the city of Iguape, (São Paulo Brazil), the dynamic of productive marine space appropriation and the knowledge involved in this practice. At the same time, looked for a comprehension of the fishing resource sharing fundamentals. These concepts were the foundation to the description of the local rules for management that are used by artisanal fishers, and for aspects of territoriality. This work borders were limited by the traditional fishers knowledge, that, together with the theory inclinations foment the scientific knowledge dialog. The final objective was demonstrating the interaction value of the human and nature, include the importance in using local rules for natural fishing resources management.

Mangrove forests get developed in distinct patterns, depending on geomorphological and environmental scenarios. Its spatial and temporal development was studied in a landscape ecology context, at the Cananéia-Iguape Coastal System. Stand and Site hierarchical levels had been used to analyze mangrove forests. At Stand level, aerial photography processing along with Geographical Information System (GIS) showed distinct spatial variations during the same 16 years period (1981-1997) in the two case areas: Mar de Cananéia and Baia de Trapandé. At Site level, mangrove forests surrounding Mar de Cananéia and Baia de Trapandé had been monitored during 2 years (2002-2004) using fixed plots, providing information on its development. Gramineous Spartina alterniflora, pioneer species and determinative for propagule establishment, colonize at first emerged sandbanks. Studied mangrove forests surrounding Mar de Cananéia are, during initial and youth phases, dominated by Laguncularia racemosa, in deposition areas, as suggested in bibliography. At Baia de Trapandé surround, the dominant species was Rhizophora mangle. Mature forests are dominated by R. mangle or Avicennia schauerianna, depending on areas characteristics. Studied mangrove forests follow model of succession seen in bibliography.

The aim of this study was to analyze short and long-term temporal variations in ichthyofauna composition and structure from sandy beaches and to understand recruitment patterns of the main species. Six beaches of the coastal system Cananéia-Iguape were sampled using a beach seine. The samples were conducted monthly from December 2008 to January 2010 for a long-term analysis, or every other day during a summer month, for a short-term analysis. Regardless the focus in short or long-term variability, most characteristics of the fish community remained the same: the juvenile fish\'s predominance, the presence few dominant and constant species, the high Trachinotus and Mugil abundance, and the variation of the ecological indexes on each beach and tide studied. The influence of the temperature in the community structure was significant only in the long-term study, showing the seasonal variation and the recruitment importance on the community patterns. T. carolinus juveniles\' recruit all over the year, while T. goodei and Menticirrhus littoralis recruit during spring. M. curema and M. hospes recruit during summer, while M. liza recruit during winter. The present study highlighted the ecological and economic importance of sandy beach shallow zone, as many species analyzed are regional important fishery resources.

Limnetic environments are biotipes of high biodiversity where a great variety of water mite taxa can be found. Their life cycle includes four phases: 1- parasitic larva, especially on insects; 2- quiescent protonymph and tritonymp; 3- predator deutonymph; and 4- adult, also predator. Despite of its ecological importance in aquatic communities, Hydracarina mites are poorly known in Brazil, with their diversity underestimated (373 species known til now). This study aims to inventory the fauna of the limnetic mites in water bodies of the coastal rain forest in the Ribeira de Iguape River (southern part of the State of São Paulo) in order to contribute for improvement of the knowledge of the group in the State. Three expeditions were performed in three areas: Campina do Encantado State Park, in Pariquera-Açu; Caverna do Diabo State Park, in Eldorado, and Ilha do Cardoso State Park, in Cananéia, from March 2011 through January 2012 to collect mites in lentic and lotic habitats. A total of 805 mites, distributed in six superfamilies, thirteen families, eighteen genera and 26 species were found. Taxonomic and morphological studies were performed using both optical phase contrast and scanning electron microscopy. Larval stages of Hydryphantes ramosus Daday and Clathrosperchon minor Lundblad are described. A dichotomous identification key of the fauna found based on adults is given.

The proposal oft his research aims three main goals: explain the formation processes of beach ridges and dune ridges alignments; undestand the way as these coastal ridges are linked with the evolution and interaction of the Quaternary depositional systems of the Una-Juréia coastal plain; and reconstitute in the time the Holocene evolution of this plain, in the context of the regional pattern of relative sea level variation, based on sedimentological attributes and absolute dating by Termoluminescence or Optically Stimulated Luminescence (TL/OSL) methods. ln the Una coastal plain, the strandplain depositional system is homogeneous, with monotonous developrnent of continuous and parallel coastal ridge alignments. The pattem of grain-size variation transverse to the ridges is characterized by fining of medium diameter and decreasing of standard deviation in direction to more recent alignments. In the heavy minerals assemblages, there are evidences of post deposìtional dissolution increasing with the age of ridge alignment. ln the Juréia plain, the spatial patterns of sedimentological variations, beach-ridge alignment geometry and longshore paleodrift drrection are more complex, due to the more confined and larger estuarine-lagoonal inlets. The more intemal coastal ridges have higher ZTR index and finer and better-sorted grain-size than the intermal ridges. A paleo-inlet near to Juréia hill would induce, by hydraulic jetty effect, a local inversion (to SW) in the net longshore drift at the northeast part of the Juréia paleobeach. With the gradual deactivation of this inlet, the longshore drift at this area acquired the regionally dominant direction (to NE). In the mid-southwest portion of the plain, the Ribeira de lguape inlet was located in the current valley of the Suá Mirim creek, few kilometers to NE from its current position. The longshore drift to NE from this inlet was also inverted by hydraulic jetty effect. With the closing of this paleo-inlet and activation or intensification of the inlet in this new positìon, the longshore drift in the area to NE from the Suá Mirim river acquired the current directìon, to NE. The TL ages obtained in the transverse profiles in the Una and Juréia coastal plains, and in paleodune and paleobeach samples collected along the Juréia beach, are suggestive of deposition in Holocene, The areas with more intense erosion in process coincide with those where the current coast line truncates the bunch of beach-dune ridges with declination for SW, formed to NE from Ribeira do Iguape pareo-inlet (Suá- Mirim valley). Thus, the local inversion of the coastal drift, due to the change of position of Ribeira de Iguape inlet, can be one of the determinant factors to the intense coastal erosion observed during the last decades in the mid-southwest part ofthe Juréia beach.

The monitoring and quality control of the aquatic environment and the evaluation of the health of oysters produced are fundamental to a safe and sustainable production of these bivalves. This study aimed to describe the microbiological profile, parasitological and toxicological and histopathological changes of Crassostrea rhizophora e produced in the Marine Extractive Reserve Bay Iguape-BA. We collected 600 species of oyster and 120 samples of water from November 2013 to November 2015. The results showed that the oysters were satisfactory sanitary quality according to Brazilian and international laws. In the determination of toxic metals in the specimens there was contamination of 6.67% for lead and 13.33% for cadmium being associated with this rainfall peaks. Were identified bacteria, protozoa and metazoan, but no notifiable and that showed no significant damage to bivalves. It is concluded that the oysters grown in RESEX Iguape Bay have good general health and microbiological quality and satisfactory parasite. In addition, histopathological changes observed no significant dimensions for the characterization of the lesion confirming the good health of oysters. It emphasizes the need management strategies, monitoring and quality control continuous, to reduce microbiological, parasitological and chemical contamination, supervision to prevent new pollution sources, and the inclusion of maximum limits for toxic metals and parasites to establish mandatory reporting on health programs mollusc order to maintain the safety of oysters for consumption, strengthening the safe and sustainable production of native oysters and ensure food and nutrition security of consumer.
O monitoramento e controle da qualidade do ambiente aquático e a avaliação da saúde das ostras produzidas são fundamentais para uma produção segura e sustentável desses bivalves. O presente trabalho objetivou estabelecer o perfil microbiológico, parasitológico e toxicológico e as alterações histopatológicas de ostras Crassostrea rhizophorae produzidas na Reserva Extrativista Marinha Baía do Iguape-Bahia. Foram coletadas 600 espécimes de ostra e 120 amostras de água dos viveiros entre novembro de 2013 a novembro de 2015. Os resultados demonstraram que as ostras apresentaram qualidade microbiológica satisfatória conforme as legislações brasileira e internacional. Na determinação de metais tóxicos nos espécimes observou-se contaminação em 6,67% das amostras para chumbo e 13,33% para cádmio sendo este dado associado aos picos pluviométricos. Foram identificados bactérias, protozoários e metazoários, porém nenhum de notificação obrigatória e que não apresentaram danos significativos ao organismo dos bivalves. Conclui-se que as ostras cultivadas na RESEX Marinha Baía do Iguape apresentam bom estado geral de saúde e qualidade microbiológica e parasitária satisfatórias. Além disso, as alterações histopatológicas observadas não apresentam dimensões significativas para caracterização de lesões confirmando a boa saúde das ostras. Ressalta-se a necessidade da adoção de estratégias de manejo, monitoramento e controle de qualidade contínuos, com o fim de reduzir contaminações microbiológicas, parasitológicas e químicas, de fiscalização para evitar que novas fontes de contaminação surjam, bem como a inclusão de limites máximos para metais tóxicos e da determinação de parasitos de notificação obrigatória nos programas de sanidade de moluscos bivalves de forma a manter a inocuidade das ostras destinadas ao consumo, fortalecendo a produção segura e sustentável de ostras nativas e garantir a segurança do consumidor.

O sistema Cananéia-Iguape é um grande complexo de canais lagunares e estuarinos, localizado no sul do estado de São Paulo. Este sistema passou a receber as águas do rio Ribeira de Iguape após a abertura do canal do Valo Grande, finalizado no ano de 1852. Este canal tornou-se a principal rota de transporte das produções da região do Vale do Ribeira, e nas décadas de 1940 a 1990 as atividades de mineração da região contaminaram o rio Riberia de Iguape, causando alterações nas características originais do sistema Cananéia-Iguape. Este estudo avaliou os níveis de urânio e tório nas amostras de sedimentos superficiais deste sistema. Esta avaliação foi feita através de um método espectrofotométrico utilizando Arsenazo III. As amostras foram digeridas em um forno micro-ondas com aplicação de HNO3, HF e H2O2. As concentrações de urânio variam de 1,3 mg·kg-1 a 5,8 mg·kg-1 e as de tório de 0,82 mg·kg-1 a 12,1 mg·kg-1. Estes resultados foram comparados com os dados da região, e observou-se que as concentrações determinadas são similares. O índice de geoacumulação foi calculado, classificando a região como \"Não contaminada a moderadamente contaminada\" para urânio e \"Não contaminada\" para tório, indicando que não há contaminação por estes metais. Estes resultados podem ser considerados como a concentração basal da região. As avaliações estatísticas identificaram uma maior afinidade do urânio e do tório com a fração de argila e silte. As concentrações de U e Th não apresentaram um comportamento homogêneo ao longo do sistema estudado.

Os metais têm origem natural como componentes das rochas e nesta situação não apresentam riscos aos seres vivos. Atualmente existem poucos estudos relacionados à obtenção de valores de referência para concentrações naturais de metais em solos do Brasil, o que dificulta a ação dos órgãos fiscalizadores e algumas instituições em monitorarem os ambientes que podem ter sido contaminados por indústrias ou outros tipos de empreendimentos. Este trabalho teve como objetivo propor valores de referência para concentração dos metais Cd, Co, Cr, Cu, Pb, Mn, Ni e Zn em solo do entorno na Baía do Iguape. As amostras foram digeridas em forno de micro-ondas com cavidade utilizando o procedimento da Agência de Proteção Ambiental, EPA 3051A e para as determinações dos analitos foi empregada a espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES). As linhas de emissão selecionadas foram, em nm: Cd II 226,502; Co II 228,615 nm; Cr II 267,716; Cu Il 213,598; Mn II 257,610; Ni II 216,555; Pb II 220,353; e Zn I 213,857. A validação foi feita avaliando-se os limites de detecção (LOD) e de quantificação (LOQ), a faixa linear de trabalho, precisão, análise de material de referência certificado e testes de adição e recuperação. O procedimento validado foi aplicado na caracterização dos solos formados a partir de sedimentos da Formação Barreiras, Arenito e Folhelho, quanto às concentrações dos analitos Cd, Co, Cu, Cr, Mn, Ni, Pb e Zn no entorno da Baía de Iguape. As faixas de concentrações obtidas para as áreas estudadas foram, em mg kg-1: Barreiras encosta: Cd (0,57 - 1,7), Co (4,5 - 5,7), Cr (33 - 73), Cu (7,0 - 16), Mn (74 - 123), Ni (5,0 - 13), Pb (4,8 - 16) e Zn (12 - 30); Barreiras plana: Cd (0,20 - 0,67), Co (1,3 - 2,2), Cr (23 - 48), Cu (3,2 - 4,8), Mn (46 - 56), Ni (4,2 - 12), Pb (2,5 - 8,3) e Zn (12 - 24); Arenito 1 Cd (0,12 - 0,43), Co (0,30 - 0,90), Cr (4,9 - 14), Cu (1,7- 4,1), Mn (12 - 30), Ni (1,2 - 3,7), Pb (2,7 - 7,5) e Zn (1,8 - 8,6); Arenito 2 : Co (0,7- 2,0), Cr (5,6 - 19,8), Cu (1,7 - 3,1), Mn (10 - 28), Ni (1,9 - 4,0), Pb (1,7 - 4,4) e Zn (1,7 - 6,5); Arenito 3 Cd (0,10 - 0,23), Co (0,40 - 1,5), Cr (2,9 - 12), Cu (1,2 - 4,5), Mn (15 - 31), Ni (1,0 - 4,0), Pb (2,6 - 6,6) e Zn (2,1 - 7,3); Folhelho Cd (0,32 - 1,1), Co (0,92 - 1,7), Cr (37 - 63), Cu (3,6 - 7,2), Mn (27 - 39), Ni (4,4 - 9,3), Pb (3,2 - 11) e Zn (10 - 18). De um modo geral as concentrações obtidas variaram na seguinte ordem decrescente Barreiras> Folhelho> Arenito. Para propor valores de referência para solos com características similares aos analisados, foram selecionadas as áreas Barreira encosta e Arenito 3 e aplicou-se a correlação linear de Pearson e análise de componentes principais (PCA), para selecionar quais parâmetros (metais e atributos) contribuem de forma efetiva para a elaboração das equações do modelo estatístico. As concentrações das amostras foram estimadas de forma satisfatória com as equações elaboradas. Para os solos de Barreiras encosta apenas Co e Pb não apresentaram valores confiáveis de predição enquanto que para o Arenito 3, somente Ni não apresentou resultados confiáveis, devido ao seu baixo coeficiente de determinação.

In Brazil, the archaeological sites known as \"Sambaquis\" - shell-mounds are geographically distributed in the coastal line and near by some rivers too. The taphonomic analyses are been applied to the study of the human bones recovered from the shell-mounds sites Capelinha, Moraes and Pavão XVI all them from the valley of the river Ribeira de Iguape, South of São Paulo State, distant from the coastal line approximately 20 miles/30 km. In this brief\'s presentation I expect to show that even with fragments of bones we can contributed with some hypothesis about burial rituals and the formation process of the archaeological sites. In these analyses I use the fragmentation of the bone as one source of information about the differences between an ante-mortem, peri-mortem and pos-mortem fractures. Looking for relations between types of fractures, biomechanics aspects and position of the bones in the burial as others different types of taphonomic agents that should influenced the bone fragmentation. Recent fractures can be distinguished from old ones, and the excavation and posexcavation (laboratory) treatment should be seen as one taphonomic agent too. Weathering bone was used as an indicator of the exposure of bone to the sun. I look for fire/cremation process, cut marks, fungal actions, roots damage and animal damage too. The variables was scored by it\'s the position in each bone recovered. In the results, I\'d not found significant differences between the bone preservation between the sex. Already the presence of infantile skeletal remaining portions corroborates the hypothesis that the bone preservation it is associated with the funerary and the chemical composition of the shell-mounds deposits, but that depends very on the exhumation procedures. With regard to the difference of preservation between the archaeological levels, the individuals in the layers intermediate would present more complete bones that from the initial and final layers. The variable \"tafonomic hole\" presented more occurrences in the individuals of the layers intermediate and base and it was present in all individuals from the three sites. It\'s been analyzed almost 10.000 human bones and fragments.

Aiming to contribute for future programs and environmental planning projects in the Cananéia-Iguape and Ilha Comprida region, was made in this paper a data-collection using social, economic and environmental factors that had demonstrated the current situation of the main aspects of the region and its social-environmental vulnerability. To subsidize the analysis a conceptual model DPSIR was applied (Drivers - Pressure - State _ Impact - Response), and its result demonstrated that the region although the concentration of diverse protected areas presents signals of interference human evidences in the water quality of the estuary, such as eutrophication processes. Beyond this problem, the necessity of investments for the local development was identified in the region. The use of the DPSIR model collaborated to point problems beyond previously cited, demonstrating it as an excellent tool to support future projects of environmental planning in the region.

The objective of this research is the hydromorphodynamic characterization of the Paulista River Ribeira de Iguape sector, approaching three levels of the geomorphology research according HART (1986), to know: (a) the morphology descriptive level; (b) the superficial materials and ground descriptive level; and (c) the processes interpretation analytical level, or hydrodynamic processes. With these surveys and systematization was possible the partially understanding humid tropical environments hidromorphodynamics trends and, mainly, of the flooding plain, which can be used in the regional territorial physical planning, in view of the importance of the occupation human being on these sectors.

The teaching of Geography is a fundamentally social activity and for this reason subject to the most diverse influences that society can provide. Aggregated to this are other elements in the education of primary and secondary school pupils that transcend the scholastic institution, such as the family, friends, politics, culture and the vehicles of information we have at my disposal today. To investigate how some of these influences are manifested in teaching practice from the point of view of the pupils was one of the objectives of this research. I have sought to identify these different influences through language, taking into account possible power relationships. The concept of social representations was utilized for me to identify some influences that may occur in the Teaching of Geography in an area of ambiental interest. The municipality of Iguape in São Paulo was chosen for my investigations, due to its specific characteristics and the possibilities it offered to explore our theme. For this reason, I opted for the ambiental question, as it represents a theme in which different interests, at times contradictory, may present themselves. So I compared two schools with préuniversity/ sixth form Ensino Médio pupils, with different socioeconomic realities, through the use of compositions on the theme of \"Nature and me in Iguape\". In making this comparison in the light of the ambiental theme, I have shown that the school may be an instrument of the legitimization of certain social representations constructed in the society of which it is a part, being also able to contradict some of its curricular intentions. Another fact noted in making this research was the importance of recognizing the discussion about geographical scale for a teaching practice to be truly more critical.
