Full textAbstract:
Micro, macro and mesofauna in the soil often respond to fluctuating environmental conditions, resulting in changes of abundance and community structure. Effects of changing soil parameters are normally determined with samples taken in the field and brought to the laboratory, i.e. where natural environmental conditions may not apply. We devised a method (STAFD - soil tubes for artificial flood and drought), which simulates the hydrological state of soil in situ using implanted cores. Control tubes were compared with treatment tubes in which floods of 15, 30, 60 and 90 days, and droughts of 60, 90 and 120 days were simulated in the field. Flooding and drought were found to reduce number of individuals in all soil faunal groups, but the response to drought was slower and not in proportion to the expected decrease of the water content. The results of the simulated floods in particular show the value of the STAFD method for the investigation of such extreme events in natural habitats.

Isoxaflutole (IFT) é um herbicida utilizado para o controle em pré-emergência de uma ampla variedade de plantas daninhas de folha larga e gramíneas, especialmente quando há resistência a outros herbicidas, como glyphosate e atrazine. Apesar de seu potencial como herbicida ter sido identificado no início dos anos 90, IFT ainda é considerado um ingrediente ativo novo no Brasil e pouco se sabe sobre seus efeitos, principalmente acerca da ecotoxicidade dos produtos formulados para grupos da macro e mesofauna do solo. Este estudo teve como objetivo avaliar efeitos comportamentais, agudos e crônicos (fuga, letalidade e reprodução) do produto comercial Provence® 750 WG (750 g i.a. L-1 isoxaflutole) nos organismos de teste Eisenia andrei (minhoca) e Folsomia candida (colêmbolo) usando normas padronizadas ISO. Os resultados mostraram que as minhocas apresentam comportamento de fuga apenas em doses 300 vezes a dose de campo e redução na reprodução em doses 150 vezes a dose de campo. Para os colêmbolos não foi obtida resposta de fuga, letalidade ou reprodução nas doses avaliadas. A partir dos resultados de laboratório, presume-se que o produto comercial Provence® não apresenta toxicidade para minhocas e colêmbolos, mesmo em doses muito acima à dose de campo, garantindo a segurança das comunidades do solo.

This research was conducted to study the population and diversity of soil and leaf litter mesofauna in arable soils under different types of vegetation and slope at the Agriculture Experimental Field (AEF) of University of Lampung. This study was designed to use the survey method. The soil and leaf litter samples were taken from different vegetation and slope classes. Observational variables included population and diversity index of soil mesofauna (H’), soil temperature, soil moisture content, soil pH, soil organic-C, soil total-N, and soil C/N ratio. The data of population distribution were presented in a boxplot diagram and the correlation between soil properties and mesofauna population or mesofauna diversity index were presented. The results showed that the most abundant soil mesofauna was observed in the plots with sugarcane vegetation, either sampled at the end of dry season (November 2015) or at the beginning of rainy season (April 2016). However, the highest number of leaf litter mesofauna was found in the plot with cassava vegetation. This result suggests that the cassava leaf litter most likely became the preferred substrate for mesofauna. In all treatments, the value of mesofauna diversity index (H‘) was categorized as low according to the Shannon-Weaver index. Two dominant orders frequently found in almost all vegetation types were Acarina and Collembola. The results of correlation analysis indicated that only soil pH sampled on November 2015 was positively correlated with the mesofauna population (range of pH 5.0 to 6.6). Soil moisture content sampled on November 2015 and soil C/N ratio sampled on April 2016 were positively correlated with the diversity index of soil mesofauna, respectively. Soil total-N sampled on November 2015 was negatively correlated with the soil mesofauna diversity index. The increase of leaf litter biomass appeared to promote the increase of the leaf litter mesofauna population, but not the diversity index.Keywords: diversity index, leaf litter, soil mesofauna, vegetation

This research was conducted to study about abundance and diversity of soil and litter mesofauna to the effect of forest cover change that occurred in the Pemerihan Resort, Bukit Barisan Selatan National Park. This research was compiled in a completely randomized design (CRD) and there were four different lands, which were: (1) primary forest, (2) coffee plantation, (3) corn field, and (4) grassland. The observation of mesofauna was taken in soil and litter from four different lands cover. The variable of observation were mesofauna abundance and diversity index, soil chemical properties (pH, organic carbon, total nitrogen, P available, and exchanged potassium), and soil physics properties (bulk density, soil temperature, humidity, and porosity). Data were analyzed using F test and further test using least significant differences (LSD) at 5%. The results showed that the different of lands cover affect the diversity index of litter mesofauna, the abundance of litter and soil mesofauna, yet did not affect the diversity index of mesofauna underground. However, the abundance and diversity index of soil and litter mesofauna in the primary forest was higher than the other lands.

Full textAbstract:
Le sol est une des composantes essentielles au soutien du fonctionnement de l’écosystème. Il est lesupport de la production primaire, un habitat pour la diversité biologique et remplit de nombreux processus écologiques. Les activités anthropiques, et parmi elles, les pratiques agricoles intensives, ont conduit à des déséquilibres au sein du sol causant un fort déclin de leur biodiversité. En réponse à ces effets, de nouvelles pratiques agricoles ont été développées pour préserver les sols et les services écosystémiques qu’ils fournissent. Ces pratiques dites innovantes s’appuient principalement sur la réduction du travail du sol, une gestion intégrée des résidus de culture, l’installation d’un couvert végétal permanent ou encore l’introduction de légumineuses dans les rotations de culture. C’est dans ce contexte de mutation des pratiques agricoles que s’inscrit ce sujet de thèse qui vise à mieux comprendre les effets de l’adoption de ces gestions innovantes sur (i) la diversité des communautés de la macro- et de la mésofaune du sol et (ii) sur le fonctionnement du sol en termes de stockage ducarbone organique (source de nourriture de base), de structure du sol et de distribution de la taille des pores (milieu de vie). Au cours des différents chapitres de ce travail, nous avons mis en évidence trois actions liées à des pratiques agricoles innovantes combinant des approches expérimentales in et ex situ. L’objectif de la première action visait à étudier l’effet combiné de l’introduction de légumineuse (féverole) et de la réduction du travail du sol sur le compartiment endogé. Pour y répondre, nous avons développé une conception expérimentale empirique faite avec la combinaison des situations rencontrées dans les fermes. Nos résultats ont montré que l’interaction entre les deux pratiques innovantes n’a pas entrainé d'augmentation significative de la diversité de la faune du sol. Les fonctions microbiennes ainsi que la dynamique du carbone (C) et de l’azote (N) ne semblent pas non plus être affectées par ces pratiques. Il s’avère que les effets bénéfiques de ces pratiques innovantes ne peuvent être envisagés sans prendre en compte la manière dont elles sont mises en oeuvre à l’échelle des rotations culturales et des itinéraires techniques. Cela nous a permis de valoriser une seconde action dont l’objectif était de suivre dans les mêmes conditions pédoclimatiques et mêmes itinéraires techniques, l'effet à long terme (quatre ans) de cinq régimes de gestion différents sur les communautés de faune du sol. Les traitements comprenaient des combinaisons de différentes cultures (annuelles, vivaces), de différents taux de fertilisation azotée (ajout d'azote, azote réduit),incorporation ou élimination de résidus de culture et différentes intensités de labour (labour vs. travail superficiel). Les résultats ont montré que la réduction de l’intensité du travail du sol a favorisé la diversité des collemboles et ses groupes fonctionnels grâce à l’amélioration des conditions de l’habitat à travers l’augmentation de la biomasse microbienne de carbone (source trophique). Par ailleurs, les autres composantes de la gestion, soit la « réduction des apports d’azote » et la « restitution / exportation des résidus de culture», n’ont pas eu d’effet sur les collemboles (abondance et richesse), notamment sur ceux vivants dans le sol, qu'ils soient hémi ou euédaphiques. Toutefois, cette étude démontre que la dissemblance dans la composition des assemblages de collemboles augmente avec la différenciation temporelle des pratiques agricoles et le travail du sol est le premier facteur responsable de cette trajectoire. Cette assertion a donné lieu à une troisième action dont l’objectif était de suivre sur une saison de végétation la conversion de la perturbation mécanique résultant du travail du sol sur la résistance et résilience fonctionnelle des assemblages biotiques édaphiquesSoil is one of the essential components supporting the functioning of the ecosystem. It is the support of primary production; an habitat for biodiversity, and it fulfills many ecological processes. Human activities, including intensive agricultural practices, have led to impaired the soil causing a sharp decline in their biodiversity. In response to these effects, new agricultural practices have been developed to preserve the soils and the ecosystem services they provide. These so-called innovative practices rely mainly on the reduction of tillage, integrated management of crop residues, the installation of permanent plant cover or the introduction of legumes into crop rotations. It is in this context of changes in agricultural practices that this thesis topic lays. This thesis aims to better understand the effects of the adoption of these innovative management practices on (i) the diversity of the macro and mesofauna communities soil and (ii) soil functioning in terms of organic carbon storage (basic food source), soil structure and pore size distribution (living environment). During the different chapters of this work, we highlighted three actions related to innovative agricultural practices combining in situ and ex situ experimental approaches. The aim of the first action was to study the combined effect of the introduction of legume (faba bean) and the reduction of tillage on the endogenous compartment. To answer this question, we developed an empirical experimental design made with the combination of situations encountered on farms. Our results showed that theinteraction between the two innovative practices did not result in a significant increase in the diversity of soil fauna. Microbial functions and the dynamics of carbon (C) and nitrogen (N) also do not seem to be affected by these practices. It turns out that the beneficial effects of these innovative practices cannot be considered without taking into account how they are implemented at the scale of crop rotations and technical itineraries. This allowed us to promote a second action whose objective was to follow, under the same pedoclimatic conditions and the same technical itineraries, the long-term effect (four years) of five different management regimes on the communities of soil fauna. Treatments included combinations of different crops, different rates of nitrogen fertilization, incorporation or removal of crop residues and different plowing intensities. The results showed that the reduction of tillage intensity favored the diversity of Collembola and its functional groups by improving habitatconditions through the increase of microbial carbon biomass (trophic source). In addition, the other components of management, namely the "reduction of nitrogen inputs" and the "restitution / export of crop residues", had no effect on springtails (abundance and wealth), in particular on those living in the soil, whether hemi or euedaphic. However, this study demonstrates that the dissimilarity in the composition of Collembola assemblages increases with the temporal differentiation of agricultural practices, and tillage was the main factor responsible for this trajectory

Previous issue date: 2009-03-27The present work was carried through in a property of familiar agriculture of situated ecological base, in the locality Colônia Maciel, Pelotas, RS, Brazil. The objective of the work was to characterize quantitatively and qualitatively some groups of organisms to mesofauna (Acari, Collembola, Diplura and Protura) and the macrofauna (Formicidae, Larvae of Coleopter and Díptera and Isopoda) of soil in ecological system base in the culture of the grapevine, in which, received applications of Calda Bordalesa and the biofertilizer Supermagro are carried through. An area of grapevine orchard (ecological handling) and another one with native bush at two moments of collection had been studied two distinct areas. The first collect was in 03/10/2006 and second in 14/03/2007. Two methodologie of collect of soilborne of were used the Trap of Tretzel and the Funnel of Tüllgren. It was analyzed for the two areas, the two moments of collection and both the methodologies some physical parameters (temperature and humidity of the ground), chemical parameters (Carbon of the ground, H + Al, macronutrients and micronutrients) and biological parameters as: frequency and constancy of the soilborne. For both methods collected, the biggest population of organisms found in the orchard/grapevine in the first collect revealing more frequent the groups Formicidae and Diplura through the method of the Trap of Tretzel. The Acari and Formicidae groups are more frequent in the orchard/grapevine, in the two collections through the method of the funnel of Tüllgren and in the second collection the groups Acari and Collembola through the method of the Trap of Tretzel had revealed more frequent. The Acari group presented the biggest index of constancy for both the areas and collections through the method of the Funnel of Tüllgren, being that, Acari and Collembola had always revealed constant with the use of the Trap of Tretzel. The capacity of exchange of cátions presented the same values in both the collections in the orchard/grapevine not showing interference in the edafic 8 fauna. The application of bordalesa Calda intervened in the frequency of the Acaris and Collembolas groups in the soil surface. The alimentary habit of the Acari and Formicidae groups favored these organisms.
O presente trabalho foi realizado em uma propriedade de agricultura familiar de base ecológica situada no município de Pelotas, na localidade Colônia São Manuel, RS, Brasil, cujo objetivo foi caracterizar quantitativamente e qualitativamente alguns grupos de organismos pertencentes à mesofauna (Acari, Collembola, Diplura e Protura) e a macrofauna (Formicidae, Larvas de Coleóptera e de Díptera e Isopoda) do solo em um sistema de produção de base ecológica. Foram estudadas duas áreas distintas uma área de pomar de videira (manejo ecológico) e outra com mata nativa em dois momentos de coleta. A primeira coleta se deu em 03/10/2006 e a segunda em 14/03/2007. Utilizou-se duas metodologias de coleta de organismos edáficos a Armadilha de Tretzel e o Funil de Tüllgren. Analisou-se para as duas áreas, nos dois momentos de coleta e ambas as metodologias alguns parâmetros físicos (temperatura e umidade do solo), parâmetros químicos (Carbono do solo, H + Al, macronutrientes e micronutrientes). E por fim parâmetros biológicos como: freqüência e constância dos grupos faunísticos selecionados. Para ambos os métodos de coleta, a maior população de organismos encontrados no pomar/videira foi na primeira coleta mostrando-se mais freqüente os grupos Formicidae e Diplura através do método da Armadilha de Tretzel. Os grupos Acari e Formicidae são mais freqüentes no pomar/videira, nas duas coletas através do método do funil de Tüllgren e na segunda coleta mostraram-se mais freqüentes os grupos Acari e Collembola através do método da Armadilha de Tretzel. O grupo Acari apresentou o maior índice de constância para ambas as áreas e coletas através do método do Funil de Tüllgren, sendo que, Acari e Collembola mostraram-se sempre constantes com a utilização da Armadilha de Tretzel. A capacidade de troca de cátions apresentou os mesmos valores em ambas as coletas no pomar/videira não mostrando interferência na fauna 6 edáfica. A aplicação da calda bordalesa interferiu na freqüência dos grupos Acaris e Collembolas na superfície do solo. O hábito alimentar dos grupos Acari e Formicidae favoreceu esses organismos.

Any inappropriate soil management, cause negative environmental impact on the diversity of soil fauna. This dissertation aimed to evaluate the influence of land use systems (LUS) on the morphological diversity of springtails, as well as its relationship with physical and chemical soil attributes. Were studied five LUS on the Plateau of Santa Catarina, Brazil: native forest (F), Eucalyptus plantation (Reu), perennial pasture (P), integrated crop-livestock (ILP) and no-tillage (PD), in two different seasons (winter and summer). The evaluation was performed by installing traps of type Pitfall traps per sampling grid (3 x 3). The same points were evaluated physical and chemical soil attributes. The morphotyping of the springtails consisted in observing five characteristics and each feature has been assigned a partial value of Eco-morphological index (EMI) for Biological Quality of Soil Index (QBS) modified. The data were subjected to multivariate analysis. In winter, the LUS (F) presented the highest abundance of morphotypes due the best values of Ca/Mg ratio, total organic carbon (TOC), bioporos, micropores and soil moisture in comparison to other LUS. ILP systems and PD already correlated with the Macropores. In the summer, again the F showed the highest abundance of morphotypes, however, the greatest diversity of levels of adaptation was found in PD. In summer, the F presented related to the TOC and micropores, while ILP and PD correlated with pH, bioporos and soil density. In winter, the value of QBS was greater in F, followed by Reu, P, PD and ILP, respectively, being smaller the higher the intensification of the LUS. In the summer, the QBS values were higher in F, followed by ILP, Reu, PD and P, respectively. The separation to the level of morphotypes proved an efficient alternative to indicate the level of intensification of land use, especially in combination with other explanatory environmental variables
Todo e qualquer manejo inadequado do solo, causa impacto ambiental negativo sobre a diversidade da fauna edáfica. A presente dissertação objetivou avaliar a influência de sistemas de uso e manejo do solo (SUS) sobre a diversidade morfológica de colêmbolos, bem como sua relação com atributos físicos e químicos do solo. Foram estudados cinco SUS no Planalto Catarinense, Brasil: floresta nativa (F), reflorestamento de eucalipto (Reu), pastagem perene (P), integração lavoura-pecuária (ILP) e plantio direto (PD), em duas épocas distintas (inverno e verão). A avaliação dos colêmbolos foi realizada instalando-se armadilhas do tipo Pitfall traps em um grid amostral (3 x 3). Nos mesmos pontos foram avaliados atributos físicos e químicos do solo. A morfotipagem dos colêmbolos consistiu na observação de cinco características e para cada característica foi atribuído um valor parcial do índice ecomorfológico (EMI) para a obtenção do Índice de Qualidade do Solo (QBS) modificado. Os dados foram submetidos a análises multivariadas. No inverno, o SUS F apresentou a maior abundância de morfotipos devido a melhores valores de relação Ca/Mg, carbono orgânico total (COT), bioporos, microporos e umidade do solo em comparação aos demais SUS. Já os sistemas ILP e PD se correlacionaram com o atributo macroporos. No verão, novamente a F apresentou maior abundância de morfotipos, porém, a maior diversidade de níveis de adaptação foi encontrada em PD. No verão, a F apresentou relação com o COT e microporos, enquanto ILP e PD se correlacionaram com pH, bioporos e densidade do solo. No inverno, o valor de QBS foi maior em F, seguido por Reu, P, PD e ILP, respectivamente, sendo menor quanto maior a intensificação do SUS. Já no verão, os valores de QBS foram maiores em F, seguido por ILP, Reu, PD e P, respectivamente. A separação ao nível de morfotipos se mostrou uma eficiente alternativa para indicar o nível de intensificação de uso do solo, principalmente em conjunto com outras variáveis ambientais explicativas

Full textAbstract:
A mesofauna edáfica compreende pequenos invertebrados que vivem nos primeiros centímetros do solo e na serapilheira. Sabe-se que o plantio de leguminosas com espécies arbóreas não fixadoras de nitrogênio melhora a fertilidade do solo, porém não se conhece o efeito desses plantios nos invertebrados edáficos. Diante disso, objetivou-se, com este estudo, avaliar o efeito de plantios puros e mistos de Eucalyptus grandis e Acacia mangium na mesofauna edáfica e estabelecer relações da mesofauna com os atributos químicos do solo e da serapilheira e os microbiológicos do solo, a fim de se construir um novo indicador de qualidade do solo. Para tanto, em outubro de 2015 (estação seca) e março de 2016 (estação chuvosa) foram avaliados os atributos físico-químicos da serapilheira (Ca, Mg, N, P, C, C/N, C/P, Mn, Cu, Fe, Zn, umidade), microbiológicos do solo (C mic, respiração do solo e atividade da desidrogenase), a umidade do solo e a mesofauna do solo e da serapilheira (riqueza, densidade e diversidade de mesofauna). Já os atributos químicos do solo (pH, Ca, Mg, C, N, P, Al, H+Al, Na, K) foram avaliados apenas em outubro. A média dos atributos foi comparada pelo teste de Tukey a 5%, enquanto que correlações, regressões e análises multivariadas foram feitas para estabelecer relações entre a mesofauna e os atributos do solo e da serapilheira e, posteriormente, construir um indicador geral de qualidade do solo. A fauna que habita a serapilheira, os atributos microbiológicos do solo e o indicador geral de qualidade do solo apresentaram maiores valores na estação chuvosa. A umidade foi muito correlacionada com os atributos biológicos do solo e da serapilheira. Foram também constatadas diferenças entre tratamentos, sendo que na estação seca há preferência da mesofauna pelo hábitat solo, possivelmente com a prevalência de relações mutualísticas entre microrganismos e mesofauna, enquanto há uma expressiva preferência da mesofauna pela serapilheira durante a estação úmida.Soil mesofauna comprises small invertebrates that live in the first centimeters of the soil and in the litter. The consortium between leguminous trees and non-nitrogen-fixing tree species improves soil fertility, but the effect of these plantations on edaphic invertebrates is not known yet. Thus, we aimed at evaluating the effect of pure and mixed plantation of Eucalyptus grandis and Acacia mangium on the invertebrates that inhabit the soil and litter. We looked for correlations between those plantations, soil and litter chemical attributes and soil microbiological attributes to create a general indicator of soil quality in Acacia mangium (AC), Eucalyptus grandis (EU) and mixed plantations of Acacia and Eucalyptus (M). The chemical litter attributes evaluated were Ca, Mg, N, P, C, C/N, C/P, Mn, Cu, Fe, Zn, besides soil and litter moisture, soil microbiology (microbial carbon, soil respiration and dehydrogenase activity) and soil and litter mesofauna (richness, density and diversity) in two seasons: October 2015 (dry season) and March 2016 (rainy season). Soil chemical analyses (pH, Ca, Mg, C, N, P, Al, H+Al, Na, and K) were from samples collected in October. We made comparisons of the means between forest systems, and established a general indicator of soil quality based on regressions and multivariate analyses, to identify correlations between mesofaunaand chemical and microbiological attributes. Litter mesofauna, microbial activity and the general indicator of soil quality presented much higher values in the rainy season than in the dry season. Moisture correlated positively with most of the soil and litter biological attributes. There were few differences between the forest systems; although we observed a clear mesofauna preference for soil as habitat in the dry season, possibly linked to the prevailance of mutualistic interactions between soil mesofauna and microorganisms, while the mesofauna showed great preference for the litter as habitat during the moist season.

The variables were: precipitation, soil properties (pHágua, pHSMP, electrical conductivity, organic carbon, nitrogen, carbon / nitrogen, phosphorus, potassium, calcium, magnesium, iron, aluminum, sodium, manganese, copper and zinc), attributes Soil physical (moisture and temperature), agronomic responses (yield and biomass) and soil macrofauna and mesofauna. Sowing of summer species occurred in December 2007, while those of winter, in May 2008. Grain crops were harvested at the end of their cycle, while forage in summer and winter amounted to seven six cuts successive, respectively. The results of soil temperature, soil moisture, yield, agronomic and representatives of the fauna were subjected to analysis of variance, mean test (Duncan 5%) probability. The fauna found was also analyzed for density, richness, relative frequency, classification by Abundance, diversity index and evenness index. Results related to soil fauna, macronutrients, micronutrients and soil conductivity were also submitted to multivariate analysis. The Fertilizers compost and organic-mineral was associated more effectively the majority of taxos, justifying larger the variation of data the exception of the catch of the soil inner in the culture of aruana. In experiment 1 the groups Acari, Lepidoptera, Diptera, Coleoptera, Oligochaeta and Nematoda and nitrogen content, zinc, magnesium, manganese, phosphorus and calcium were those who 9 had contributed more in variation of the data. In experiment 2 the groups Isopoda, Diplura, Myriapoda, Acari and Dermaptera and the magnesium, nitrogen, phosphorus, zinc, copper, sodium, aluminum and iron were those who had contributed more in variation of the data. In experiment 3 the groups Lepidoptera, Hymenoptera, Diplura, Myriapoda, Protura and the magnesium, nitrogen, iron and manganese were those who had contributed more in variation of the data. In experiment 4 the groups Acari, Nematoda, Dermaptera, Protura, Diplura, Coleoptera and Oligochaeta and the contents of potassium, iron, copper and calcium were those who had contributed more in variation of the data.
O estudo foi realizado em uma propriedade rural, na localidade da Hidráulica no município de Capão do Leão - Rio Grande do Sul, Brasil, com objetivo de avaliar a influência dos fertilizantes mineral, organo-mineral e orgânico sobre a macrofauna e mesofauna do solo. Foram dispostos quatro experimentos individualizados em delineamento estatístico blocos casualizados com cinco tratamentos e seis repetições cada, em um ARGISSOLO AMARELO Distrófico típico, franco arenoso. Utilizou-se as seguintes culturas em sucessão: Zea mays L.-Consórcio forrageiro (Trifolium repens L., Trifolium pratense L., Lotus corniculatus L. e Lolium multiflorum Lam.); Sorghum bicolor L.-Brassica napus L.; Panicum maximum-Lolium multiflorum Lam.; Helianthus annuus L.-Triticum aestivum L. Investigaram-se os seguintes tratamentos: T1-Testemunha, T2-Fertilizante mineral, T3-Fertilizante organo-mineral, T4-Fertilizante-composto e T5-Fertilizante orgânico cama de peru . As variáveis analisadas foram: precipitação, propriedades químicas do solo (pHágua, pHSMP, condutividade elétrica, carbono orgânico, nitrogênio, carbono/nitrogênio, fósforo, potássio, cálcio, magnésio, ferro, alumínio, manganês, sódio, cobre e zinco), atributos físicos do solo (umidade e temperatura), respostas agronômicas (rendimento de grãos e de fitomassa) e a macrofauna e mesofauna do solo. A semeadura das espécies de verão se deu no mês de dezembro de 2007, enquanto as de inverno, foram a partir de maio de 2008. As colheitas foram realizadas nas culturas de grãos no final do respectivo ciclo, enquanto, nas forrageiras de verão e de inverno totalizaram-se sete e seis cortes sucessivos, respectivamente. Os resultados de temperatura do solo, umidade do solo e rendimento agronômico e representantes da fauna foram submetidos à análise de variância, teste de médias (Duncan 5%) de probabilidade. A fauna encontrada também foi submetida à análise de Densidade, Riqueza, Freqüência relativa, classificação por categoria de Abundância, índice de diversidade, índice de equitabilidade. Os resultados referentes à fauna edáfica, macronutrientes, micronutrientes e condutividade elétrica do solo foram submetidos também a análise multivariada. Conclui- se que: a menor diversidade e equitabilidade foram encontradas no Fertilizante mineral nas coletas realizadas no interior do solo do consórcio forrageiro, da canola, da aruana e do trigo. Assim como, nas coletas de superfície que mostram no milho, no consórcio forrageiro, na canola e na aruana e azevém os menores índices ecológicos. Os grupos Collembola, Acari, Hymenoptera e Coleoptera mostraram as maiores densidades entre os experimentos. O rendimento agronômico do milho e da aruana e azevém influenciaram mais na disposição da fauna edáfica nas coletas de interior do solo, enquanto que, nas coletas de superfície a maior contribuição foi no consórcio forrageiro no sorgo e no trigo. Aos Fertilizantes, composto e organo-mineral associaram-se mais efetivamente a maioria dos táxons, justificando-se a maior variação dos dados levantados nas coletas de interior e superfície do solo a exceção das coletas de interior do solo na cultura da aruana. No experimento 1 os grupos Acari, Lepidoptera, Diptera, Coleoptera, Oligochaeta e Nematoda e os teores de nitrogênio, zinco, magnésio, manganês, fósforo e cálcio contribuíram mais efetivamente com a variação dos dados. No experimento 2 os grupos Isopoda, Diplura, Myriapoda, Acari e Dermaptera e os teores de magnésio, nitrogênio, fósforo, zinco, cobre, sódio, alumínio e ferro contribuíram mais efetivamente com a variação dos dados. No experimento 3 os grupos Lepidoptera, Hymenoptera, Diplura, Myriapoda, Protura e os teores de magnésio, nitrogênio, manganês e ferro contribuíram mais efetivamente com a variação dos dados. No experimento 4 os grupos Acari, Nematoda, Dermaptera, Protura, Diplura, Coleoptera, e Oligochaeta e os teores de potássio, ferro, cobre e cálcio contribuíram mais efetivamente com a variação dos dados.

Full textAbstract:
South Africa is one of the most important mining countries in the world, hosting the world's largest reserves of platinum group metals (PGMs). Even though mining is clearly an important activity in South Africa, contributing approximately US$ 7.4 billion annually to the countries' gross domestic product (GDP), the costs to the environment are not insignificant. One of the most severe environmental aspects associated with mining is the storage of mineral waste on tailings storage facilities due to their impacts on air quality, ground water quality, aesthetics and land use. It is also unknown whether the environmental effects of tailings storage facilities increase or decrease over time. The aim of this study was to determine the ecotoxicity of platinum tailings storage facilities of different ages by means of soil physical and chemical analysis, earthworm ecotoxicological studies, dehydrogenase activity and soil mesofauna studies. Samples were obtained from three platinum tailings storage facilities of different ages of which two were already rehabilitated while the third was still operational at the time this study was performed. The latter was used as a negative control for the purpose of the study. Soil samples were physically and chemically analysed. Earthworm ecotoxicological studies were conducted to determine changes in biomass, reproduction, mortality, neutral red retention times and tissue metal concentrations. Dehydrogenase activity was determined before the introduction of earthworms and manure, after introductions of manure and after introductions of earthworms and manure. Soil mesofauna were extracted and identified in order to determine species richness, diversity, abundance and functional grouping. Soil chemical analysis indicated that concentrations of certain heavy metals, especially chrome (Cr), present in platinum tailings materials could have a potential effect on microorganisms, microbial processes and earthworms. Earthworm ecotoxicological results indicated that earthworms that bioaccumulated higher levels of heavy metals showed poor hatchability of cocoons. Dehydrogenase activity indicated that earthworms play a significant role in increasing the number and biomass of soil microbes because significant increases in dehydrogenase activity were noticed after the addition of earthworms to platinum tailings materials. Results from the earthworm ecotoxicological studies, dehydrogenase activity, and soil mesofauna composition indicated that environmental impacts of tailings storage facilities did not increase with age, but is more likely to be an indication of the rehabilitation measures administered to the different tailings storage facilities.Thesis (M.

Apple crops have huge importance to South Brazil economic, which concentrate more than 95% production in country. There are use of many pesticides in apples, with emphasis to fungicide Mancozeb and insecticide Chlorpyrifos. Although these substances have been developed to acting in a specific group of organisms, they are potentially dangerous to all alive organisms direct or indirectly exposed. Depending on persistence and toxicity, pesticides could interfering in soil basics process, how respiration and fauna soils activity, that directly influence nutrients cycling, organic matter decomposition and improvement physical chemical characteristics, being this products a risk to soil. Not application only, but handle and cleaning of machines with residues are dangerous to environmental too, and could induce punctual contamination. In some countries, to complete degradation of this waste, there is a bed for biological degradation, called Biobeds. Ecotoxicoly is a tool that could be used to measure pesticide risks and from their wastes to environmental receptor – since microorganisms until superiors vertebrates, having international protocols to application of assays. The aim of this study, was investigate toxicity caused by Mancozeb and Chlorpyrifos in two different Oxisols, representatives to apple crops, and effluent of pulverizer tank with wastes, to establish risks doses to three organisms from soil - Folsomia candida (Colembolla), Enchytraeus crypticus (Enchytraedae) e Eisenia andrei (Lumbricidae), using ISO protocols, and analyses Biobeds about its toxicity to organisms after contamination, comparing to natural soils, observing use possibility in handle of pesticides with spill simulation. Chlorpyrifos show higher toxic than Mancozeb, especially to Collembola (LC < 1 mg kg-1). Earthworm, organism used in Brazil’s law to approve pesticides was less sensible than other 18 19 for both products. Lethal and reproduction assays showed different risk doses in soils. Biobeds reduced waste pesticide risks during time and this not happen in one natural soil, that indicate dissolving products its not enough to reduce or eliminate the risks for soil organisms. In spill simulation, Biobeds was efficient in eliminate toxicity to earthworms and enchytraeids, although, not to Collembola and long time assays are necessary to reduce Chlorpyrifos toxicity to this organism. Due to large number of active ingredients using in agriculture actually, deep impact pesticide studies in soil organisms are necessary and alternatives of this wastes discharge
O cultivo de maçã tem grande representatividade na economia da região Sul do Brasil e uma série de agrotóxicos é utilizada, destacando-se o fungicida Mancozebe e o inseticida Clorpirifós. Apesar de essas substâncias serem desenvolvidas para atuar em um conjunto de organismos alvo, são potencialmente danosas para todos os organismos vivos expostos aos produtos. Dependendo de sua persistência e toxicidade, os agrotóxicos podem interferir em processos básicos do solo, tais como a respiração e a atividade da fauna edáfica que reflete diretamente na ciclagem de nutrientes, decomposição da matéria orgânica e melhoria de atributos químicos e físicos, representando estes compostos um risco para o solo. O manuseio e limpeza de maquinário com resíduos o produto também são potencialmente perigosas ao ambiente, podendo causar contaminações pontuais. Em alguns países para a completa degradação deste resíduo, são utilizados leitos biológicos de descarte (Biobeds). A ecotoxicologia é uma ferramenta que pode ser utilizada para mensurar o risco dos agrotóxicos e seus resíduos a receptores ambientais. O objetivo desta dissertação foi avaliar a toxicidade causada pelos ingredientes ativos Mancozebe e Clorpirifós em dois solos representativos para a cultura da maçã no Sul do Brasil – Latossolo e Nitossolo, e do efluente do tanque pulverizador com resíduos destes produtos, a fim de estabelecer dosagens de risco a três organismos representantes da fauna edáfica – Folsomia candida (Colembolla), Enchytraeus crypticus (Enchytraedae) e Eisenia andrei (Lumbricidae), e analisar Biobeds quanto a sua toxicidade aos organismos após sua contaminação, quando comparado aos solos analisados, observando a possibilidade de uso dos Biobeds para descarte de efluentes de agrotóxicos e como contensão em caso de derrame acidental. Foram realizados ensaios laboratoriais utilizando 14 15 protocolos ISO para ensaios letais (14 dias) e subletais (28 dias para colêmbolos e enquitreídeos e 56 dias para minhocas) de ecotoxicidade com os organismos indicados em câmara a 20ºC e fotoperíodo com 8/16 horas de luz/escuro. O Clorpirifós mostrou-se mais tóxico que o Mancozebe, principalmente aos colêmbolos, que são afetados em ensaios letais e subletais por doses < 1 mg kg-1. As minhocas, únicos organismos utilizados na legislação brasileira para credenciamento de agrotóxicos no mercado mostraram-se menos sensíveis que os colêmbolos e enquitreídeos aos dois produtos testados para ensaios letais (CL50), e subletais de reprodução (CE50), que apresentaram doses de risco distintas, e o Latossolo apresentando maior toxicidade quando contaminado pelos agrotóxicos testados. Os Biobeds reduziram a toxicidade dos agrotóxicos ao longo do tempo para os organismos edáficos, o que não foi observado no Latossolo, mostrando que mesmo um resíduo muito diluído, como o da lavagem do equipamento de aplicação, pode oferecer risco a fauna do solo ao longo do tempo. Na simulação de derrame acidental, os Biobeds foram eficientes em eliminar a toxicidade para minhocas e enquitreídeos, mas não para os colêmbolos, sendo necessários ensaios a longo prazo para determinar a possibilidade de redução da toxicidade do Clorpirifós aos organismos nesta situação. Devido ao grande número de ingredientes ativos utilizados na agricultura atualmente, são necessários estudos mais profundos do impacto destes agentes químicos à fauna edáfica, e também das alternativas de descarte dos resíduos oriundos dessa atividade

O objetivo deste trabalho foi estudar a fauna edáfica ocorrente no processo de vermicompostagem dos resíduos de erva-mate, borra de café, estercos bovino, equino e ovino, assim como, analisar química e fisicamente estes materiais. Estes substratos foram armazenados em vasos plásticos com capacidade de 10 litros, em bancadas horizontais em laboratório, utilizando-se um delineamento inteiramente casualizado, com cinco repetições, onde, após um período de estabilização, inoculou-se 150 minhocas da Califórnia (Eisenia foetida) em cada tratamento. Como ferramenta de análise dos dados, utilizou-se o programa estatístico DivEs® para o cálculo dos índices ecológicos de diversidade, dominância, equitabilidade e riqueza de espécies, utilizados para análises da mesofauna edáfica. Foram realizadas avaliações de macronutrientes, relação C/N, carbono orgânico, pH, densidade, umidade, contagem edáfica da mesofauna (ácaros e colêmbolos), da macrofauna (minhocas e casulos) e microorganismos (fungos totais, bactérias degradadoras de celulose e bactérias diazotróficas) além da respiração microbiana. Os resíduos estudados apresentaram resultados distintos entre si. Foi verificado uma superioridade numérica da mesofauna edáfica nos resíduos vegetais quando comparado com os de origem animal, havendo um predomínio de colêmbolos em todos os tratamentos avaliados (95%). Com relação a macrofauna, observou-se um maior número de casulos (n = 323) e minhocas (n = 236) ao final do processo de vermicompostagem, no esterco ovino. Ao longo da execução do experimento notou-se que somente no tratamento esterco bovino houve uma diminuição no desenvolvimento de bactérias degradadoras de celulose (de 6,6 x 1011 para 2,3 x 109 ), já para as bactérias diazotróficas, apenas no tratamento esterco equino ocorreu um aumento na sua população (de 6,0 x 103 para 9,5 x 107 ). Fungos totais mantiveram uma distribuição homogênea no decorrer das avaliações em todas as unidades experimentais. Na totalidade das amostras houve uma redução da respiração microbiana durante o processo de vermicompostagem, devido a maturação dos resíduos orgânicos. Observou-se uma diminuição da relação C/N, com destaque para os resíduos vegetais que apresentaram os maiores valores da mesma, entretanto, nestes resíduos foram verificados as menores concentrações dos macronutrientes P, K e Mg. Com exceção do esterco equino, o pH ajustou-se para valores recomendáveis ao final do experimento em todos os substratos. Os índices ecológicos de diversidade e equitabilidade mostraram um predomínio de organismos no esterco ovino. Diante dos resultados obtidos neste estudo, pode-se sugerir a utilização destes resíduos para a vermicompostagem, e recomendar o uso de seus vermicompostos como adubo orgânico com precauções.
The objective of this work was to study the edaphic fauna occurring in the vermicompost process of the residues of herb-checkmate, coffee drag, bovine, equine and ovine manure, as well as to analyze chemically and physically these materials. These substrates were stored in 10 liter plastic plots in horizontal laboratory benches, using a completely randomized design with five replications, where, after a stabilization period, 150 California worms (Eisenia foetida) in each treatment. As a tool for data analysis, the statistical software DivEs® were used to calculate the ecological indexes of diversity, dominance, equitability and species richness, used for analysis of the edaphic mesofauna. In this study different evaluations were made such as: macronutrients, C/N ratio, organic carbon, pH, density, humidity, counting of the edaphic mesofauna (mites and collembolans), macrofauna (worms and cocoons) and microorganisms (total fungi, cellulose-degrading bacteria and diazotrophic bacteria) and microbial respiration. The residues studied presented different results among themselves. It was verified a numerical superiority of the edaphic mesofauna in the vegetal residues when compared with the ones of animal origin, being a predominance of collembolans in all the evaluated treatments (n = 121864). With regard to macrofauna, a larger number of cocoons (n = 323) and earthworms (n = 236) were observed at the end of the vermicompost process in ovine manure. During the execution of the experiment it was noticed that only in the bovine manure treatment there was a decrease in the development of cellulose degrading bacteria (from 6.6 x 1011 to 2.3 x 109 ), already for the diazotrophic bacteria, only in the treatment equine manure occurred an increase in its population (from 6.0 x 103 to 9.5 x 107 ). Total fungi maintained a homogeneous distribution throughout the evaluations in all the experimental units. In all the samples there was a reduction of the microbial respiration during the vermicompost process due to the maturation of the organic residues. It was observed a decrease in the C/N ratio, with emphasis on the vegetable residues that presented the highest values of the same, however, in these residues were verified the lowest concentrations of the macronutrients P, K and Mg. With the exception of equine manure, the pH adjusted to values recommended at the end of the experiment on all substrates. The ecological indexes of diversity and equitability showed a predominance of organisms in ovine manure. Considering the results obtained in this study, we can suggest the use of these residues for vermicomposting, and recommend the use of their vermicompost as an organic fertilizer with the precautions.

Studies of the soil mesofauna were carried out in Tanaev meadows of the «Nizhnyaya Kama» National Park in natural and disturbed areas. The abundance of pedobionts and herpetobionts in natural areas significantly exceeded the abundance in disturbed areas. However, the taxonomic composition and trophic structure were similar. In general, communities structure indexes in natural sites indicate a stable ecosystem of floodplain meadows. The observance of pipe laying technology during further restoration of disturbed areas, high soil moisture and a small width of the disturbed soil layer contribute to the preservation and rapid restoration of the structure and population of large soil and litter invertebrates of meadow phytocenosis.
