Abstract:

Resumo O fósforo é considerado o principal fator responsável pela eutrofização de lagos e reservatórios. No presente estudo, utilizou-se um modelo transiente de mistura completa para analisar a dinâmica do fósforo em 40 lagos e reservatórios localizados nas regiões Nordeste, Sudeste e Centro-Oeste do Brasil. Os resultados con- firmaram a dependência do coeficiente de decaimento de fósforo com o inverso da raiz quadrada do tempo de residência hidráulica. No entanto, em virtude da elevada temperatura da água dos lagos e reservatórios do Nordeste, esse coeficiente assumiu valores cerca de duas vezes superiores àqueles observados em regiões de clima tropical. Por outro lado, devido à alta variabilidade de temperatura dos lagos e reservatórios do Sudes- te, o coeficiente oscilou entre valores extremos observados em regiões de clima temperado e semiárido. Em virtude disso, propôs-se uma equação geral para calcular o coeficiente de decaimento de fósforo como uma função não apenas do tempo de residência hidráulica, mas também da temperatura da água. Após validação e análise de sensibilidade do modelo proposto, o mesmo foi aplicado a um reservatório hipotético sujeito a variações temporais de volume, vazão, carga e temperatura da água. Espera-se que este modelo simplificado possa auxiliar na gestão de lagos e reservatórios brasileiros. Palavras-chave: Eutrofização. Temperatura. Qualidade da água. Abstract Phosphorus is considered the main factor responsible for eutrophication of lakes and reservoirs. In the present study, a transient complete mixing model was used to analyse phosphorus dynamics in 40 lakes and reservoirs located in the Northeast, Southeast and Central-West regions of Brazil. The results confirmed the dependence of the phosphorus decay coefficient on the inverse of the square root of the hydraulic residence time. However, due to the high-water temperature of the lakes and reservoirs of the Northeast, this coefficient assumed values about two times higher than those observed in regions of tropical climate. On the other hand, due to the high temperature variability of the lakes and reservoirs in the Southeast, the coefficient oscillated between extreme values observed in temperate and semiarid regions. As a result, a general equation was proposed to calculate the phosphorus decay coefficient as a function not only of the hydraulic residence time, but also of the water temperature. After valida- tion and sensitivity analysis of the proposed model, it was applied to a hypothetical reservoir subject to temporal variations of water volume, flow, load and temperature. This simple model will potentially assist in the management of Brazilian lakes and reservoirs. Keywords: Eutrophication. Temperature. Water quality.

Abstract:

The detailed description of rarely recorded Thalassiosira species in Brazil is presented with light microscope (LM) and scanning electron microscope (SEM) illustrations. A total of 78 phytoplankton net samples (20 µm) collected between the years 2000 and 2006 in coastal waters of southern Brazilian, Cassino Beach and the estuary of Lagoa dos Patos, were studied in cleaned material using the Axiovert Zeiss LM and Jeol 6060 SEM. Water temperature and salinity of samples and six species are presented: Thalassiosira endoseriata, T. hendeyi, T. lundiana, T. minuscula, T. oceanica and T. wongii. Two species, Thalassiosira hendeyi and T. endoseriata were the most common being observed in all seasons at Cassino Beach in a wide temperature range (10-26 ºC), while only sporadically in the estuary of Lagoa dos Patos. Thalassiosira endoseriata, T. lundiana, T. oceanica and T. wongii are for the first time reported in Brazilian coastal waters. The latter two species, rarely recorded in the world, are fully illustrated based on Brazilian material.

Abstract:

In Brazilian Amazonia, 20 genera and more than 200 species of polistine wasps are recorded. Local faunas with 70 to 80 species are usually found in non floodable forest environments. However, a variety of wetlands exist in the region, the most expressive in surface area being varzea systems. In this paper, information is presented on polistines from two areas of wetlands in the Brazilian states of Amazonas and Amapá. These are reciprocally compared and also with nearby terra firme locations. Collecting methods consisted of active search for nests, handnetting and automatic trapping of individuals. Forty-six species of 15 genera were collected in Mamirauá, AM, most being widespread common wasps. However, five species deserve special mention in virtue of rarity and/or restricted distribution: Metapolybia rufata, Chartergellus nigerrimus, Chartergellus punctatior, Clypearia duckei, and Clypearia weyrauchi. In Região dos Lagos, AP, 31 species of 9 genera were collected, nearly all being common species with the exception of some Polistes, like P. goeldi and P. occipitalis. Even though less rich than vespid faunas from terra firme habitats, the Mamirauá fauna proved to be quite expressive considering limitations imposed by the hydrological regime. In Região dos Lagos, however, the very low diversity found was below the worst expectations. The virtual absence of otherwise common species in environments like tidal varzea forests along Araguari River is truly remarkable. The causes of low diversity are probably related to isolation and relative immaturity of the region, allied to strong degradation of forested habitats.

Abstract:

RESUMO: No ano de [1889]1900 ocorreu a viagem de retorno da ex-escravizada africana Catarina Pereira Chaves, e de seus familiares brasileiros à cidade nigeriana de Lagos. Esta viagem foi recriada pelo escritor Antonio Olinto, nas linhas do romance A casa da água (1988). Nesta obra, a narrativa da experiência de brasileiros descendentes de ex-escravizados, na condição de estrangeiros na África, envolve temáticas como a estranheza, a hospitalidade e os conflitos decorrentes do ingresso desses indivíduos na ordem social, política e econômica das cidades da Costa dos Escravos, de onde anteriormente haviam sido trasladados, durante a diáspora, os seus ascendentes. Em Lagos, a comunidade brasileira organizou-se em torno dos seus grandes homens, negociantes ricos com quem se abasteciam e de quem dependiam as famílias mais desfavorecidas, constituindo uma rede de clientela, cujo sentido de unidade veio a resultar na organização e na ocupação de um bairro brasileiro denominado Brazilian Quarter. Nesse sentido, abordamos a relação entre os afro-brasileiros e os africanos que os receberam, sob o ponto de vista do binômio estranheza/hospitalidade. Tal abordagem se dá com base nos apontamentos de Jacques Derrida, a partir das noções de hospitalidade e de “hos-ti-pitalidade”, termo criado pelo filósofo para se referir às circunstâncias em que a hospitalidade é pervertida pela hostilidade. Com base nesses elementos, a partir da narrativa da mencionada obra olintiana, discorremos sobre os percursos de brasileiros na cidade de Lagos.

Abstract:

We studied the holotype and only known specimen of the rodent Calomys anoblepas Winge, 1887, an enigmatic and putatively extinct pentalophodont sigmodontine found in the limestone caves of Lagoa Santa, Minas Gerais, Brazil. Comparisons with other sigmodontines suggest that anoblepas can be allocated under the genus Juliomys González, 2000 and probably represents an extinct form within it. Cranial characters that support our generic hypothesis include the combination of an interlacrymal depression behind nasals, anterior portion of interfrontal suture with incomplete fusion, zygomatic plate nearly vertical with almost nonexistent upper free border, anterior border of the mesopterygoid fossa located at the level of third molar hypoflexus, and brachyodont molars with crested coronal topography. Juliomys includes three living species of sylvan and arboreal mice endemic of the Atlantic forests. This genus is absent in contemporaneous rodent assemblage from Lagoa Santa area, suggesting different environmental conditions during Pleistocene deposition times.

The study of an assemblage of in situ stumps of arborescents lycopods casts in a coaly sedimentary sequence in Permian (Artinskian – Kungurian) of south brazilian Gondwana, allowed to infer a higromesofilous habita for these plants. The absence of stigmarian-like apendages suggest a root system developed in soils subjected to occasional inundation. These data confirm the depositional model proposed for these successions, related to litoraneous basins (Lagon-barrier System).

Abstract:

Around forty bird species habitually reproduce in the Northern Hemisphere during summer, and migrate to the Southern Hemisphere during northern winter. These migrating birds fly together in large or small groups until they have reached the Caribbean, Central American, or Brazilian shores. Charadrius semipalmatus, Bonaparte 1825, is one of these migrating species that uses resting and feeding areas along eastern and western coasts of North and South America, with several records for the Brazilian coast, and very few for the inland country. On November 24, 2011, an individual of this species was observed on the banks of one of the lakes that compose a complex of about 40 temporary lakes within the Karst of Lagoa Santa Environmental Protection Area. On October 29 and 30, 2012 a single individual of Gelochelidon nilotica, Gmelin 1789, was also observed in Sumidouro State Park. We suggest that these specimens have used the Atlantic Ocean migration route, following the São Francisco River Basin, until the karst area. Although highly impacted, the temporary lakes within the Karst of Lagoa Santa still harbor a significant number of bird species, and serve as resting and feeding places for migratory or errant species that are still eliciting new records.

Abstract:

PURPOSE: To evaluate potential risk factors for the development of multiple sclerosis in Brazilian patients. METHOD: A case control study was carried out in 81 patients enrolled at the Department of Neurology of the Hospital da Lagoa in Rio de Janeiro, and 81 paired controls. A standardized questionnaire on demographic, social and cultural variables, and medical and family history was used. Statistical analysis was performed using descriptive statistics and conditional logistic regression models with the SPSS for Windows software program. RESULTS: Having standard vaccinations (vaccinations specified by the Brazilian government) (OR=16.2; 95% CI=2.3-115.2), smoking (OR=7.6; 95% CI=2.1-28.2), being single (OR=4.7; 95% CI=1.4-15.6) and eating animal brain (OR=3.4; 95% CI=1.2-9.8) increased the risk of developing MS. CONCLUSIONS: RESULTS of this study may contribute towards better awareness of the epidemiological characteristics of Brazilian patients with multiple sclerosis.

Abstract:

AIM: To study the distribution, structure, size and density of fish in the karst lake: Lagoa Central (Lagoa Santa, MG - surface area: 1.7 km²; mean depth: 4.0 m; and maximum depth: 7.3 m). METHODS: The hydroacoustic method with vertical beaming was applied, using the echosounder Biosonics DT-X with a split-beam transducer of 200 kHz. The analysis of the acoustic data was performed with the software Visual Analyzer (Biosonics Inc.). Thematic maps of density echoes associated with fish, estimated by the technique of echo-integration, were made using the kriging interpolation. The density and vertical distribution of insonified fish were estimated using the technique of echo-counting. RESULTS: The lake had a mean density of 0.89 echoes associated with fish per m², showing large spatial variations in the density of fish. The size estimated for the echoes associated with fish range from 2.7 to 15.9 cm (mean = 5.3 cm). CONCLUSIONS: The use of hydroacoustic to obtain rapid and realistic estimates of fish abundance and vertical distribution of the fish stock was successful

ABSTRACT Lampião, the most infamous Brazilian brigand leader, was killed and decapitated during an ambush in 1938. The Alagoas police coroner, Dr. José Lages Filho, performed an autopsy of his head. Strongly biased toward the anthropologic ideas of the famous Italian psychiatrist and criminalist Cesare Lombroso, the examination found only a few of the so-called criminal inborn traits. The Lombrosian doctrine and a number of related theories strongly influenced medical and political reasoning in the first half of the 20th century. Modern genetic and neuroscientific studies are still looking for the potential biological roots of misbehavior and criminality.

The Cerrado is one of the six Brazilian biomes and offers a wide variety of edible fruit species. This article is the result of an outreach program entitled Cagaita and Pequi, Economic and Social Importance of the Population of Sete Lagoas, created in 2014. It aimed to take information and build knowledge in the community about the possibility that the fruits of the Cerrado present, especially pequi and cagaita. He sought to contribute to raising awareness of the preservation of the environment and the inclusion of low-income local people, who can use the fruits as alternative food and generate income, thereby protecting and ensuring the survival of future generations and countless families that use the fruits. Still, he tried to contribute to the training and education of the students of the courses of Food Engineering and Bachelor's Degree in Interdisciplinary Biosystems UFSJ. As interventions were used methodology of work in Sete Lagoas and the region, with the support of leaflets, flyers and posters.

Abstract:

The rift section of the Brazilian basins represent the sedimentary record associated with the first stages of Gondwana break-up in the Early Cretaceous phase (Berriasian to Aptian). The rift succession of the Campos Basin constitutes one of the main petroleum systems of Brazil’s marginal basins. This interval contains the main source rock and important reservoirs in the Lagoa Feia Group deposits. The Lagoa Feia Group is characterized by siliciclastic, carbonate and evaporite sediments deposited during the rift and post-rift phases. Despite the economic relevance, little is known in stratigraphic terms regarding this rift interval. To date, most studies of the Lagoa Feia Group have adopted a lithostratigraphic approach, while this study proposes a tectonostratigraphic framework for the deep-rift succession of the Campos Basin (Lagoa Feia Group), using the fundamentals of seismic sequence stratigraphy. This work also aims to establish a methodological and practical procedure for the stratigraphic analysis of rift basins, using seismic data and seismofacies, and focusing on tectonicstratigraphic analysis. The dataset comprised 2D seismic lines, core and lithological logs from exploration wells. Three seismic facies were identified based on reflector patterns and lithologic data from well cores, providing an improved subdivision of the pre-, syn- and post-rift stages. The syn-rift stage was further subdivided based on the geometric patterns of the reflectors. Tectonics was the main controlling factor in the sedimentary succession, and the pattern and geometry of the seismic reflectors of the syn-rift interval in the Campos Basin allowed the identification of three tectonic systems tracts: (i) a Rift Initiation Systems Tract; (ii) a High Tectonic Activity Systems Tract and (iii) a Low Tectonic Activity Systems Tract.

Two of the species of Pectinariidae previously reported from the Brazilian coast are herein described, together with a new species and also new record for the genus Petta Malmgren, 1866 for the southern Atlantic. Amphictene catharinensis (Grube, 1870) was described from material from off Santa Catarina, southern Brazil, but the most recent description for these animals comes from Nilsson (1928); a redescription for A. catharinensis is herein provided. Pectinaria nonatoi n. sp. was informally described as P. (Pectinaria) laelia nomen nudum in an unpublished thesis and a formal description has never been provided, although the species has been reported from several other localities off the Brazilian shoreline, mostly in ecological studies; the species is formally described herein and compared to the most similar congeners. Petta alissoni n. sp. is also described and compared to the most similar congeners and this is the first record for animals of this genus from southern Atlantic. There are also records for Pectinaria gouldii (Verrill, 1874) and P. regalis Verrill, 1901 from off the Brazilian coast, and a doubtful record for Lagis pseudokoreni (Day, 1955), but we did not find any material belonging to those taxa.

Kalliapseudes schubartii (Crustacea: Tanaidacea) is a tube dwelling invertebrate living in estuarine soft bottoms with distribution along the south-east and southern Brazilian and Uruguayan coasts. Individual growth, and reproduction were examined by taking samples for a year in the estuarine region of the Lagoa dos Patos (southern Brazil). The von Bertalanffy model described growth of K. schubartii (K=4.54 y−1, L∞=13.22 mm). Reproductive activity was observed in spring and summer. No relationship was observed between total length of females and brood size. Eggs, embryos, and mancas were often observed in a marsupium. Relative growth analysis showed two levels of allometry in the growth of chelipeds of males.

Abstract:

The purpose of this study is to analyze the chemical composition of wet precipitation in samples collected at three stations in the Candiota region in the Brazilian state of Rio Grande do Sul (RS). Samples were collected in 2004. Variables analyzed in wet precipitation were pH, conductivity, and concentration of Cl-, NO3-, SO4(2-) F-, Na+, Ca2+, Mg2+, K+, NH4+, Cu, Zn, Fe, Mn, Pb, Ni, Cd, Co, and Cr. SO2 and NO2 distribution over the time were also evaluated. Results have showed that pH < 5.6 are found mostly at Candiota airport (85%), followed by Aceguá (72%) and Três Lagoas (65%). Enrichment Factor of the studied ions in wet deposition revealed higher Ca2+ and SO4(2-) enrichment in Três Lagoas. Factor Analysis applied to metals and major ions allowed identifying the major sources. While Cl-, Na+, Mg2+ are of marine origin, SO4(2-), NO3-, NH4+ ,F- come from anthropogenic sources. Except for Fe and Mn originating from the soil dust, the metals studied showed to have anthropogenic influence The average SO2 and NO2 concentration, as well as SO4(2-) and NO3- in wet precipitation in the Candiota region showed higher concentrations during the warmer months.

Abstract:

Background and aims – We revisited Florula Lagoensis, the first floristic list of the Cerrado, published in 1892 by Eugen Warming. All flowering plants were nomenclaturally and taxonomically updated and associated with type material collected by him. We also analysed the contribution of new collections made in Lagoa Santa to assess how many species were recollected after his work. Methods – We have used the list of phanerogams in Warming’s 1908 translation as primary data source and we performed a search on Brazilian virtual herbaria to retrieve all material collected at the locality of Lagoa Santa and surroundings. Key results – Out of 2270 species collected by Warming, 560 (24.7%) have been recollected after 150 years, and only 242 species (9.6%) were new additions to the list. A total of 381 (14.4%) specific or infra-specific names from Florula Lagoensis have type specimens collected by Warming. Conclusions – It is fair to recognize Eugen Warming as one of the pioneers of floristic studies in Brazil. We stress the completeness of his work and highlight the importance of following Warming’s footsteps, collecting intensively, exploring different environments, and working in a collaborative way.

Abstract:

A high-resolution seismic survey was performed on the Lagoa dos Patos, southern Brazil. The survey was conducted aboard the research vessel LARUS of the Fundação Universidade Federal do Rio Grande. The seismic profiles were obtained using a 3.5 kilohertz frequency, which provided a rather good penetration depth and resolution of the records. Results of the seismic records allowed the determination and mapping of seismic facies and seismic sequences, as well as related architectural elements, which were identified basically through the configuration patterns of the seismic reflectors. The analysis of the seismic records allowed the identification of the architectural elements that build up the sedimentary pile accumulated in the coastal prism of the State of Rio Grande do Sul, contributing to a better understanding of the geological evolution of the southern Brazilian coastal plain during the Quaternary period.

En 1988, Brasil promulgó su nueva Constitución, que representaba el acto final de la larga transición democrática iniciada una década antes. En ese momento, contrario a la tendencia dominante en el Occidente capitalista, se hizo un compromiso con el bienestar social, enfocándose en la acción estatal y en la expansión de la participación democrática como formas de superar una larga historia de desigualdad y exclusión. Las promesas constitucionales, sin embargo, no se han cumplido plenamente. El país enfrentó largos períodos de graves dificultades financieras que limitaron la capacidad de los gobiernos para actuar. Al mismo tiempo, las fuerzas conservadoras resistieron continuamente, buscando vaciar el proyecto estatal prometido en 1988. A pesar de las dificultades, la sociedad ha experimentado grandes avances, sin embargo, la ruptura soñada con una realidad de pobreza y exclusión no sucedió. Y hoy, ante un escenario de recesión económica mundial y extrema fragilidad financiera del Estado, hay voces crecientes que defienden el abandono de los valores constitucionales, apostando en los mercados como una forma de superar las dificultades actuales.

Abstract:

We present prehistoric mercury accumulation rates in a dated sediment core from Lagoa da Pata, a remote lake in São Gabriel da Cachoeira, northern Amazon. The sediment samples were subdivided for mercury and radiocarbon analyses. A group of 18 samples have been prepared at ANU for 14C dating by accelerator mass spectrometry (AMS). The dating results show a good correlation with depth in the core, down to 41,500 BP. Three distinct sections are clearly identified in the core. They consist of upper and lower organic-rich layers, separated by an inorganic layer which represents a short period of rapid accumulation around 18 ka BP. The mercury accumulation rate is found to be larger in the upper layer (18 ka to present) than in the lower one (41 ka to 25 ka), by a factor of three. The larger accumulation rate of mercury is probably associated with warmer temperatures and a higher frequency of forest fires during the Holocene.

Abstract:

The Danish naturalist Peter Wilhelm Lund (1801–1880), regarded as the father of Brazilian palaeontology and archaeology, is known mainly for his work with fossil mammals of Quaternary age from the limestone caves of the Lagoa Santa region in the state of Minas Gerais, southeastern Brazil. However, during one decade of fieldwork (1835–1844), he also collected a large number of remains of other animal groups from these caves. Birds were well represented and, following assessment by the Danish ornithologist Oluf Winge (1855–1889), most of the specimens collected by Lund belong to species still living in the area. Here we present an overview of the bird remains (fossil and recent), found by Lund and others in the region, we update their taxonomic attributions, and comment on the history of the material, making information previously published only in Danish available in English.

Abstract:

In prehistoric times, innumerous shell middens, called "sambaquis", consisting mainly of remains of marine organisms, were built along the Brazilian coast. Although the scientific community took interest in these anthropic formations, especially since the nineteenth century, their pedological context is still poorly understood. The purpose of this study was to characterize and identify the physical and chemical changes induced by soil-forming processes, as well as to compare the morphology of shell midden soils with other, already described, anthropogenic soils of Brazil. Four soil profiles developed from shell middens in the Região dos Lagos - RJ were morphologically described and the physical and chemical properties determined. The chemical analysis showed that Ca, Mn, Mg, and particularly P and Zn are indicators of anthropic horizons of midden soils, as in the Amazon Dark Earths (Terras Pretas de Índio). After the deposition of P-rich material, P reaction and leaching can mask or disturb the evidence of in situ man-made strata, but mineralogical and chemical studies of phosphate forms can elucidate the apparent complexity. Lower phosphate-rich strata without direct anthropic inputs indicate P leaching and precipitation in secondary forms. The total and bioavailable contents of Ca, Mg, Zn, Mn, Cu, P, and organic C of midden soils were much higher than of regional soils without influence of ancient human settlements, demonstrating that the high fertility persisted for long periods, at some sites for more than 4000 years. The physical analysis showed that wind-blown sand contributed significantly to increase the sand fraction in the analyzed soils (texture classes sand, sandy loam and sandy clay loam) and that the aeolian sand accumulation occurred simultaneously with the midden formation.

Abstract:

Surveys on Coccinellidae (Coleoptera) in Sete Lagoas city, Minas Gerais state, Brazil, indicated the parasitism of adults of the species Coleomegilla maculata De Geer, 1775, Eriopis connexa (Germar, 1824) and Olla v-nigrum (Mulsant, 1866), by Dinocampus coccinellae (Schrank, 1802) (Hymenoptera; Braconidae: Euphorinae). Since then, the parasitoid have been maintained in its original hosts at the Insect Rearing Laboratory - LACRI of the Brazilian Agricultural Research Institution - Embrapa Milho e Sorgo. Besides the citation of occurrence in Brazil, this work also indicates the parasitoid preference for C. maculata (70% of parasitism), followed by O. v-nigrum (43.3% of parasitism) and E. connexa (36.7% of parasitism). Total life cycle of D. coccinellae was longer on C. maculata (32.4 ± 0.48 days), compared to O. v-nigrum (29.5 ± 0.49 days) and E. connexa (27.8 ± 0.4 days). Due to the relatively high percentage of field parasitism, D. coccinellae can reduce the efficiency of biological pest control by Coccinellidae predators especially in the case of C. maculata.

Abstract:

The Brazilian city of Três Lagoas, Mato Grosso do Sul State, has experienced an urban outbreak of visceral leishmaniasis since 2000. In 2002, due to the increase in the number of cases, 46 families with cases of visceral leishmaniasis were studied to verify the prevalence of asymptomatic infection in household contacts. Indirect immunofluorescence and ELISA showed a 36.4% positive infection rate. There were no cases of symptomatic disease among these contacts. There was no statistically significant difference in gender or age. Median age was 21 years, and the 10-19-year age bracket was the most heavily affected (23%). As for family characteristics, no differences were observed in schooling or family income; most families (58.7%) owned their homes, which were built of masonry (97.8%) and had adequate infrastructure. All the families reported what were probably phlebotomine sand flies in the peridomicile. In conclusion, asymptomatic visceral leishmaniasis infection is frequent and occurs in both males and females, regardless of age.

Abstract:

Riparian forests have positive effects on water quality and biodiversity. However, most studies have only tested the effects of distinct vegetation types or streams with and without forests, despite the fact that riparian forests differ in degrees of complexity. The aim of the present study was to test whether riparian forest complexity affected the composition and abundance of the Ephemeroptera, Plecoptera and Trichoptera (EPT) taxa across a small environmental gradient. We also measured whether EPT genera or feeding groups responded to changes in riparian forest complexity. The study was conducted in two protection areas (i.e. Lagoa do Peri Municipal Park, PERI; and the Permanent Protection Area of Ratones, RAT) of Santa Catarina Island, Brazil. Primary production increased in streams with lower canopy percentage, and EPT assemblages differed among streams with different riparian forest complexity. In RAT, the water quality and forest variables affected EPT composition; however, in PERI, only water quality variables were important. Indicator species analysis based on genera suggested Kempnyia (Plecoptera) and Zelusia (Ephemeroptera) to be indicative of streams with greater forest complexity, whereas Farrodes (Ephemeroptera) was significant in streams of intermediate riparian forest complexity; however, no one functional group dominated. The results of the present study show that small changes in riparian forest complexity influence the composition of EPT insects in subtropical streams.

Abstract:

This paper provides information on the morphology and occurrence of extant diatoms of the family Asterolampraceae and Azpeitia species of the southernmost Brazilian continental shelf and slope waters in the Southwestern Atlantic Ocean (28 -34ºS), under the influence of Tropical, Subtropical, Subantarctic Waters, terrestrial discharges from La Plata River and Lagoa dos Patos lagoon. Plankton was sampled (20 µm net; vertical hauls) at the same 27 stations in winter 2005 and summer 2007. Among Asterolampraceae, Asteromphalus flabellatus was the most frequent species (57% of samples) observed mainly in winter samples (92%) in Subtropical Shelf Water but also under the influence of La Plata River plume (salinity <35). Lower frequencies were observed for Asterolampra marylandica, Asteromphalus elegans, Asteromphalus heptactis and Spatangidium arachne. Four species of Azpeitia were observed: A. barronii and A. neocrenulata for the first time in the South Atlantic Ocean while A. africana and A. nodulifer had already been registered in equatorial and southern areas of Brazil. All Azpeitia species were rare (19%) in offshore samples (100-200 m depth. Remarks on the morphology based on light and scanning electron microcopy observations are provided along with their distribution in the study area.

Abstract:

AbstractThe plumes from the rivers of the South Brazilian Bight (SBB) and South Brazil (SB) were studied using a realistic model configuration. River plume variability on continental shelves is driven by the input of river runoff into the shelf, by wind variability, and also by ambient currents and its seasonal variability, especially the Brazil Current, which are realistically modelled in this study. It is presented a simulation of 4 years using a nested configuration, which allows resolving the region around Florianópolis with very high resolution (∼150 m). The dispersion of river plumes was assessed not only with the hydrodynamical model results but also by using passive tracers whose dynamics was analyzed seasonally. Several dyes were released together with the river discharges. This approach allowed calculating the depths of the riverine freshwater, and the resulting regions affected by the plumes. Northward intrusions of waters from the southern region, under the potential influence of the distant La Plata river plume, were evaluated with a Lagrangian approach. The local river plumes are confined to the inner shelf, except south of 30°S where discharges from Lagoa dos Patos disperse over the shelf in the spring and summer. The Brazil Current flowing southward over the slope prevents the river plumes from interaction with oceanic mesoscale dynamics. The river plumes are, thus, mainly controlled by the wind forcing. The plumes from SBB are able to disperse until SB following the southward wind regime typical of the summer. And both the SB and La Plata river plumes are also able to reach SBB, forced by the northward wind typical of the winter season, until the latitude of 25.5°S. A low salinity belt (below 35) is present along the coastal region of SB and SBB year-round, supported by contributions from both the large and small rivers. The interaction between the different plumes influences the dispersion patterns, shielding the Florianṕolis coastal region from plumes of distant rivers, and dispersing the plume of SBB rivers away from Santa Catarina Island as it disperses southward during the summer months.

Abstract:

Eastern South America, or what is today Brazilian territory, poses interesting questions about the early human occupation of the Americas. Three totally distinct and contemporaneous lithic technologies, dated between 11,000 and 10,000 14C BP, are present in different portions of the country: the Umbu tradition in the south, with its formal bifacial industry, with well-retouched scrapers and bifacial points; the Itaparica tradition in the central-west / northwest, totally unifacial, whose only formal artifacts are limaces; and the "Lagoa Santa" industry, completely lacking any formal artifacts, composed mainly of small quartz flakes. Our data suggests that these differences are not related to subsistence or raw-material constraints, but rather to different cultural norms and transmission of strongly divergent chaînes opératoires. Such diversity in material culture, when viewed from a cultural transmission (CT) theory standpoint, seems at odds with a simple Clovis model as the origin of these three cultural traditions given the time elapsed since the first Clovis ages and the expected population structure of the early South American settlers.

Abstract:

Abstract A new species of rodent is added to the highly diverse genus Oecomys (Cricetidae, Sigmodontinae, Oryzomyini) based on specimens collected in the Argentinian provinces of Chaco and Formosa. The new species is characterized by a derived carotid circulatory pattern, a feature shared with O. concolor, O. mamorae, and O. sydandersoni. A unique combination of morphological, morphometric, and molecular characters, however, provides unambiguous evidence of its validity as a separate entity. Individuals of the new species are larger than other representatives of Oecomys, and their skulls have wide and cuneate interorbital regions with well-developed supraorbital shelves, long incisive foramina, long palates, absent alisphenoid struts, and broad Eustachian tubes. This new Oecomys appears to be endemic to the Humid Chaco, an ecoregion listed as Vulnerable due to the human impact. Preliminary observations suggest that several specimens from Eastern Paraguay and the Brazilian Pantanal could also be assigned to the new species described herein. Una nueva especie es adicionada al altamente diverso género de roedores Oecomys (Cricetidae, Sigmodontinae, Oryzomyini), sobre la base de especímenes coleccionados en las provincias Argentinas de Chaco y Formosa. La nueva especie se caracteriza por un patrón de circulación carotídea derivado, un rasgo compartido con O. concolor, O. mamorae y O. sydandersoni. Sin embargo, la combinación única de caracteres morfológicos, morfométricos y moleculares provee evidencia inequívoca sobre su validez como una entidad separada. Individuos de la nueva especie son de mayor tamaño en comparación con otros Oecomys y sus cráneos tienen una región interorbitaria ancha y acuñada con plataformas supraorbitarias bien desarrolladas, forámenes incisivos largos, paladares largos, ausencia de las barras alisfenoideas y tubos de Eustaquio anchos. Este nuevo Oecomys parece ser endémico del Chaco Húmedo, una ecorregión considerada como Vulnerable debido al impacto antrópico. Observaciones preliminares sugieren que varios especímenes de Paraguay Oriental y del Pantanal Brasilero podrían también ser asignados a la nueva especie aquí descrita.

Abstract:

This study investigated strontium isotopes in the dental enamel of 32 human skeletons from Forte Marechal Luz sambaqui (shellmound), Santa Catarina, Brazil, aiming at identifying local and non-local individuals. The archeological site presents pot sherds in the uppermost archeological layers. Dental enamel was also examined from specimens of terrestrial fauna (87Sr/86Sr = 0. 71046 to 0. 71273) and marine fauna (87Sr/86Sr = 0. 70917). The 87Sr/86Sr isotope ratio for individuals classified as locals ranged from 0. 70905 to 0. 71064 and was closer to the isotope ratio of the seawater than to the ratio of the terrestrial fauna, indicating a strong influence of marine strontium on the inhabitants of this sambaqui. The results indicate the existence of three non-local individuals (87Sr/86Sr = 0. 70761 to 0. 70835), buried in both the level without pottery and the layer with pottery, possibly originated from the Santa Catarina Plateau, close to the municipality of Lages, or from the Curitiba Plateau. The occurrence of a slight difference between the isotope ratios of local individuals buried in the archeological layer without pottery, when compared to those in the layer with pottery, suggests a possible change in dietary patterns between these two moments in the site's occupation

Hydroponics has drawn huge interests by Brazilians in semi-arid regions due to the lack of water and fertilizer use. The objective of this study was to evaluate the growth and yield of lettuce cultivars in the hydroponic system in two planting seasons and different irrigation regimes. The research was carried out in Campus II / UEPB and followed a 2 x 6 x 3 factorial scheme in randomized blocks, represented by two planting seasons (the summer and the winter), six lettuce cultivars (Elba, Great Lakes, Mimosa Rose, Simpson, American, Cristina), three irrigation regimes (15 min, 30 min, 45 min) and five replications. The hydroponic system used was the NFT. For nutrition, Hidrogood Fert® solution (Compound + Calcium + Iron) was applied. At the 40th day after sowing, green and dry leaf biomass, green stem biomass, leaf area, leaf area index and productivity were analyzed. After that, the variance analysis was performed by the F-test for 5% of probability and the Scott-Knott test for comparison of the averages. The high temperatures caused very small growth in the stem of the Simpson cultivars, independent of the irrigation regime used. Besides the highlight of the American cultivars, the other cultivars presented satisfactory performance in the climatic conditions of Lagoa Seca / PB.

Abstract:

The identification of species of Apistogramma Regan, one of the most diversified cichlid genus, found in lakes Amanã and Urini, and tributaries (Amanã Sustainable Development Reserve), Japurá-Solimões drainage, Brazilian Amazon, is herein presented. Individuals of the genus collected in the area were previously classified in eight morphotypes separated in A. agassizii, A. cacatuoides and six unidentified types. After detailed analyses, it was concluded that these eight morphotypes belonged, in fact, to five species. The diagnosis for each species is presented, as well as an identification key for the area. Briefly, individuals formerly identified as Apistogramma sp.2 belong to a species, possibly yet undescribed, of Pertensis group, thus classified as Apistogramma gr. pertensis. Apistogramma sp.3 was identified as A. hippolytae and Apistogramma sp.4 as Apistogramma cf. eunotus. Individuals formerly classified as A. cacatuoides are, in fact, A. bitaeniata. Individuals formerly classified as Apistogramma sp.1 are, in their majority, young specimens of A. agassizii, and few A. bitaeniata. Individuals at first classified as A. agassizii really correspond to the referred species. The results made possible the prompt identification of occurring species, aiding additional scientific studies and the further use of these species in the ornamental fishes management by Amanã Reserve riverine communities.

Abstract:

When employed in a focused manner, corporate performance evaluation has proven to be instrumental for entrepreneurs as an important tool that contributes with performance improvements at their organizations. The descriptive study herein, prepared as of a questionnaire comprising 46 queries, poses to analyse the performance of micro and small companies (MSEs) by employing the multicriteria methodology for constructive decision aiding (MCDA-C). As of respondent replies, MCDA-C descriptors were formed, shaping six prime groups so as to identify relevant factors that drive or hinder MSE success. The questionnaire was applied to managers in charge administering 25 small and medium-sized companies of Lages, a city within the Brazilian state of Santa Catarina. Study findings provide evidence as to the fact that (i) 24% of surveyed companies, tend to go bankrupt; (ii) managerial functions at the MSEs are the prime source of influence on negative outcomes; (iii) from a financial control standpoint, surveyed companies fall far shorter than the minimum level deemed necessary to qualify as satisfactory; (iv) those that present the best results, operate both within the domestic and international markets; (v) the study placed under the spotlight the group “Evolution Stage”, evidencing the trend of ever increasing MSE expansion. This study revealed that corporate failure contributing factors are intensely interconnected and largely depend on the entrepreneur´s own performance, the prime contribution of findings residing in demonstrating that MCDA-C can be employed to analyse the performance of micro and small businesses.

Objective: Describe and discuss the use of action research in the Pharmaceutical Assistance restructuring of primary care in the city of Lagoa Santa/MG (Brazil), for the implementation of comprehensive medication management services.Methods: An action research project, based on fortnightly thematic discussions with a group of ten pharmacists, was used as a management tool to foster the engagement and critical reflection of pharmacists involved in the construction of their clinical practice in primary care.Results: Action research encouraged pharmacists to think about their practices and to perceive the need for a clearer definition of their roles and responsibilities in primary care. The collective development allowed pharmacists to recognise their weaknesses and strengths, identifying themselves as professionals capable of assuming co-responsibility for the pharmacotherapy of the patient. The re-organization of the service was necessary to provide support for actions related to the logistic of medicines, so pharmacists could dedicate time to their clinical practice.Conclusion: Action research can be an effective instrument of reflection, motivation and empowerment for the pharmacist team to meet the challenges of the Brazilian Unified Health System (Sistema Único de Saúde, SUS).

Abstract:

Dinoflagellates of the genus Ceratium are generally marine organisms, but rare occurrences in freshwater have been observed in Brazil. In this paper we are recording for the first time the presence of Ceratium furcoides, an invasive species, in a shallow, natural intermittent pool formed at a high-altitude at the southern end of the Iron Quadrangle, an iron-mining district of Minas Gerais State (Southeast Brazil). Samples were collected in October and November of 2010 (rainy period). The population density of this organism observed in Lagoa Seca (“Dry Pool”) was very low, at most 4 ind L–1. Mountain lakes are extremely vulnerable to atmospheric deposition of organisms, making them valuable witnesses both of the many forms of impact arising from human activities and of the extended global connections that facilitate the dispersion and introduction of new species over great distances. Studies on the population dynamics of C. furcoides in natural tropical systems are still rare and very recent to the brazilian scenario and hence the monitoring of its dynamics and the potential impact on aquatic communities of its becoming established are essential to an understanding of the process of bioinvasion by this species.

Abstract:

This study aimed to evaluate the agronomic performance of 24 sorghum genotypes in four Brazilian regions and the chemical characteristics of genotypes grown in Sete Lagoas, state of Minas Gerais. Genotypes BRS655 and 12F37005 had higher average production of green matter (> 44 ton ha-1) and dry matter (> 17 ton ha-1), respectively. Genotypes 12F38019, 12F40019, 12F37005, 12F37043 and Volumax took more days to flower in three of the four municipalities (75-90 days). Genotypes 12F38006, 12F40006 and 12F37016 were taller (> 2 m). Values of dry matter, crude protein and neutral detergent fiber ranged from 37.15 to 50.13; 5.51 to 10.28 and 43.57 to 65.69%, respectively. The genotypes were not different regarding acid detergent fiber content, with mean value of 34.83%. Genotypes 12F38019, 12F37016, 12F39005, 12F39019, 12F37007, 12F37014, 12F39014 and BRS 655 showed the best values of dry matter digestibility (64.31 to 74.20%) and crude protein content (8.33 to 10.28%). Among them, 12F139014 exhibited the lowest lignin content (3.32%), suggesting less effect of this fraction on digestibility. Genotype 12F39014 is the most suitable for cultivation, as it presented the best nutritional value and good dry matter production in the four municipalities.

Institutional assessment and pedagogical political project: two sides of the same coinThis article intends to analyze the articulation between institutional assessment (IAS) and pedagogical political project (PPP) based on a project conducted in a Brazilian municipality. It involved a sample of schools that developed a process for institutional assessment, in order to re-shape their PPP. We sought to examine whether and how these schools used the data from this assessment to reformulate their pedagogic projects. The text brings a reflection about the principles that guide and surpass the two processes. It aims both to evaluate the reason why it is so difficult to develop them and what their possibilities are.Keywords: Institutional Assessment; Pedagogical Political Project; Basic Education; Quality of Education.

Abstract:

The Ostreidae are well known for their high intra-specific variation, which makes identification problematic. The present paper aims to provide a morpho-anatomical and taxonomic review of the Brazilian species of Crassostrea, as well as some congeneric species from other relevant areas. The Brazilian species are Crassostrea mangle sp.nov. and Crassostrea brasiliana. The exotic species Crassostrea gigas, cultivated in the southern region of the country, is also included in this study. Additional species are: Crassostrea virginica, from the Atlantic coast of the USA, the type species, and Crassostrea rhizophorae, a south-eastern Caribbean species that is supposed to occur in Brazil, but is here understood as a different entity endemic to that region. Taking into account their economic importance, the differentiation between these species is critical, and is essential for a better planning of production and preservation strategies. We point out the differences in almost all structures amongst these species, which are formally redescribed herein. The occurrence of the African species Crassostrea gasar in Brazil is established as false. The voucher specimens of previous studies responsible for this assumption were examined, evidencing a misidentification for Crassostrea brasiliana from an estuarine environment. The geographical distribution of the studied species is recognized as follows: Crassostrea rhizophorae in the south-east Caribbean Sea; Crassostrea mangle sp. nov. from Pará to the Santa Catarina, only in mangroves; Crassostrea brasiliana from Paraíba to Santa Catarina, both in rocky shores and mangroves; Crassostrea virginica ranges from the Atlantic coast of Canada to the Caribbean; and Crassostrea gigas originates from the Indo-Pacific, but has been introduced in southern Brazil. This paper also deals with conchological aspects of the endemic species Crassostrea praia, from south Lagoa dos Patos, Rio Grande do Sul; after a more detailed definition, and considering the deleterious effects of the nearby port and construction sites, it can be classified as an endangered species.

O Programa Mais Alimentos Internacional combina a convencional cooperação técnica em agricultura com uma linha de crédito direcionada a pequenos agricultores moçambicanos para aquisição de maquinário brasileiro para o mercado agrícola. O objetivo deste artigo é analisar o processo de implementação do PMAI em Moçambique. Para tanto, realiza cerca de quarenta entrevistas no Brasil e em Moçambique, uma pesquisa de campo de quinze dias em onze municípios de Moçambique, inclusive na zona rural, e análise de comunicação telegráfica entre os governos brasileiro e moçambicano. Acombinação dessas técnicas permitiu concluir que a) o PMAI em Moçambique não impactou significativamente nenhum dos lados envolvidos na cooperação, b) o Brasil pode superar o discurso tradicional da diplomacia e se beneficiar dacooperação sul-sul através de ganhos comerciais e c) o PMAI, embora tenha proporcionado aumento da produtividade dos agricultores moçambicanos de forma geral, esbarrou no problema do acesso ao mercado.Palavras-chave: Programa Mais Alimentos Internacional.

This article aims at analyzing MFP’s implementation in Mozambique, goal that was fulfilled through the following techniques - almost forty interviews in Brazil and Mozambique, a field research in eleven Mozambican municipalities, including the rural zone, and analysis of telegraphic communication between Brazilian and Mozambican governments. The combination of these techniques showed that a) MFP did not materially impact any of the sides involved in this cooperation, b) Brazil can overcome traditional diplomatic discourse and benefit from south-south cooperation through commercial gains and c) MFP enables Mozambican farmers to increase their productivity but comes into conflict with market access issues.Keywords: More Food International Program.

Abstract:

Na Caatinga, semiárido brasileiro, nós comparamos a ocorrência de ninhos da formiga cortadeira (Atta sexdens) em duas áreas do município de Contendas do Sincorá, estado da Bahia: uma área perturbada por pecuária (Fazenda Lagoa das Covas: FLC), e uma protegida e com áreas preservadas de Caatinga (Floresta Nacional Contendas do Sincorá: FNCS). Nós também testamos se os ninhos de A. sexdens são mais abundantes próximos às estradas não pavimentadas. Nenhum ninho foi registrado na FNCS, em contraste, 35 ninhos foram registrados na FLC (3,6 colônias ha-1). O número de ninhos de A. sexdens claramente diminuiu com o aumento da distância da estrada, que variou de 0 a 140 m. Ninhos também foram observados nas estradas do lado de fora da FLC e da FNCS. Nós sugerimos que estradas podem estar facilitando a expansão de A. sexdens nas áreas de caatinga do município de Contendas do Sincorá. Nós esperamos que a presença de A. sexdens irá manter ou mesmo aumentar os efeitos dos distúrbios promovidos pelo gado na vegetação da FLC. Se o estabelecimento de A. sexdens na FNCS também for bem sucedido, nesta área protegida poderá ocorrer um processo de homogeneização e empobrecimento, favorecendo o estabelecimento de espécies de plantas associadas a perturbações antrópicas. É possível que outras áreas da Caatinga estejam sendo submetidas ao mesmo processo de invasão por Atta favorrecido por estradas pavimentadas e não-pavimentadas.

Abstract:

The Serra do Urubu mountain range is considered a key biodiversity area. It is situated in the Pernambuco Endemism Center, one of the most threatened regions of the Brazilian Atlantic Forest. However, despite the high importance of this area little research on its herpetofauna has been performed. The present study presents an inventory of the herpetofauna of the region, through bibliographic review, searches in museum collections and field expeditions to the RPPNs Frei Caneca and Pedra D’Antas, in the municipalities of Jaqueira and Lagoa dos Gatos. The conservation status of the amphibians of the region is discussed. Five expeditions, between 2012 and 2013 were made. The methods employed were visual transect surveys, acoustic census and pitfall traps. We recorded a total of 46 amphibian species, belonging to nine families: Craugastoridae (3 spp.), Bufonidae (3 spp.), Ranidae (1 sp.), Hylidae (25 spp.), Leptodactylidae (8 spp.), Odontophrynidae (1 sp.), Hemiphractidae (2 spp.), Phyllomedusidae (2 spp.) and Microhylidae (1 sp.). We recorded 42 species of squamates: 16 species of lizards families Phyllodactylidae (1 sp.), Gekkonidae (1 sp.), Gymnophthalmidae (1 sp.), Polychrotidae (1 sp.), Leiosauridae (1 sp.), Tropiduridae (3 spp.), Dactyloidae (2 spp.), Diploglossidae (2 spp.), Teiidae (2 spp.), Scincidae (1 sp.), and Iguanidae (1 sp.); and 24 species of snakes: Boidae (3 spp.), Colubridae (2 spp.), Dipsadidae (13 spp.), Elapidae (2 spp.), Typhlopidae (1 sp.), and Viperidae (3 spp.). The occurrence of rare and/or threatened species such as the snakes Dipsas sazimai, Lachesis muta and Sibynomorphus sp. and the amphibians Hylomantis granulosa, Chiasmocleis alagoana, Boana freicanecae and Phyllodytes gyrinaethes reinforces the need for conservation measures at this highly threatened region of the Atlantic Forest.

Abstract:

Pseudis minuta is abundant in a variety of aquatic environments of the Pampa domain. Therefore, it can be considered a good model for testing hypotheses on environmental heterogeneity and the influence of climate on the activity of anurans. In this study, we examined the spatial distribution pattern of P. minuta in terms of microhabitats and the influence of abiotic factors on seasonal fluctuations in the abundance of this species. Samples were collected monthly from April 2008 to May 2009 in wetlands and coastal dunes in the Lagoa do Peixe National Park. A total of 112 specimens of P. minuta were collected, of which 45 were found in the wetland area and 67 in the dune area. The species showed seasonal fluctuation in abundance, and it was most abundant in months with higher temperatures (spring-summer). Pseudis minuta was mainly associated with aquatic vegetation, an expected pattern in terms of their morphological adaptations to this environment. Among the abiotic parameters analyzed, only the monthly mean temperature showed a significant correlation (p < 0.05; r = 0.67) with the abundance of P. minuta. We concluded that P. minuta is a generalist species with respect to microhabitat use and also that fluctuation in its population abundance is mainly associated with seasonal variation in temperature.

Abstract:

Giovanni Casaretto published Eugenia rotundifolia Casaretto (1842: 40) using material that he collected in Restinga vegetation between Copacabana and Lagoa Rodrigo de Freitas, Rio de Janeiro, Brazil. Berg (1857: 287) treated E. rotundifolia Casaretto as a distinct species, and recognized two varieties. However, the binomial E. rotundifolia (Walker-Arnott 1836: 335) Wight (1841: 17) was previously published for a taxon occurring in Sri Lanka. Therefore, Casaretto’s name is a later superfluous homonym and illegitimate. In a recent article on the typification of plant names published by Casaretto, Delprete et al. (2019) proposed E. casarettoana Delprete (2019: 25) as a substitute name for E. rotundifolia Casaretto. However, Delprete and his collaborators overlooked that the name E. casarettoana O. Berg (1857: 520) was previously published using material collected by Martius near the town of Coari, state of Amazonas, Brazil, and belongs to a distinct species occurring in the Brazilian Amazon. Also, Berg (1857) spelled the specific epithet “casaretteana” without explaining to whom he dedicated the epithet. It is obvious that it was dedicated to Casaretto, as no other botanist or plant collector has a similar last name. Therefore, according to Recommendation 60C of the ICN (Turland et al. 2018), the spelling of this epithet should be corrected to casarettoana, as it has been done for this and other specific epithets dedicated to Casaretto (Delprete 2016).
