“…In addition, and especially to the Collembola taxon, a population elevation of the Folsomia Candida species was evidenced during the January/2014 collections -a specie widely used in ecotoxicological studies, that formed colonies of young animals perceived in greater numbers in the SCP in NT of forage turnip, blue and wheat lupine even without the using of magnifying glasses. In this sense, the results are aligned with the considerations of Scoriza et al (2015). The authors, when studying the effect of herbicides on the biota in a sandy-loam soil in Rio de Janeiro in 2014, found values more favorable to the increase of the reproduction of the species Folsomia candida.…”

“…Systems that favor the permanence of biomass under the ground, such as tillage, as well as the use of good cultural practices that aim increasing organic carbon in the soil, and the life maintenance of invertebrates have been boosted in recent decades (BARETTA et al 2014;BEDANO et al 2016). Although there are still many questions regarding soil fauna, little is known about the intra and interspecific complexity of invertebrates in the soil and thus the constant reorganizations and reconfigurations influenced by anthropic action need further studies (KROLOW, 2011;SANTOS et al 2015).…”

RESUMO:O presente estudo teve como objetivo avaliar a população da fauna edáfica em uma área experimental instalada há 26 anos em Pato Branco / PR. Entre os tratamentos existentes na área experimental, foram selecionados seis manejados sob sistema de cultivo convencional, e seis manejados sob plantio direto, ambos cultivados com seis diferentes plantas de cobertura. O método empregado para a extração de organismos edáficos (camada 0-10 cm) foi o do Funil de Tüllgren. A execução das coletas se deu em blocos e repetições (156 amostras de solo para quantificar a fauna edáfica; 156 para avaliar a umidade do solo e 156 leituras de temperatura do solo). Em abril/2013, foram estimados 60.138 indivíduos m -2 e em janeiro/2014 foram 28.348 indivíduos m -2 . A adoção do plantio direto por longo período favorece a biodiversidade da fauna do solo em relação ao solo que vem sendo feito revolvimento com duas lavrações e quatro gradagens anuais desde 1976. Os táxons edáficos mais representativos em abril/2013 foram Acari, Collembola e Diptera, e em janeiro/2014 foram Acari, Collembola, Hymenoptera e Larva de Lepidoptera. O manejo fitossanitário das áreas influencia na diversidade da fauna edáfica. O fator abiótico umidade do solo atua de forma severa sob a fauna edáfica, sendo mais evidente no sistema de cultivo convencional. A época de coleta influencia na densidade de indivíduos, na riqueza de espécies e nos índices de Shannon e Pielou.Palavras-chave -macrofauna, mesofauna, plantas de cobertura de inverno.ABSTRACT -The present study had as objective to evaluate the soil fauna population, in an experimental sites installed for 26 years in Pato Branco / PR. Among the treatments existent in the experimental site, were selected six managed under Conventional Farming System, and six managed under No-tillage, both cultivated with six different cover plants. The method used for the extraction of edaphic organisms (0-10 cm depth) was Tüllgren funnel. The collection was done in blocks and replicates (156 soil samples to quantify the soil fauna; 156 to evaluate soil moisture, and 156 soil temperature readings). In the April/2013, 60,138 m -2 individuals were estimated, and in the January/2014 they were 28,348 m -2 individuals. The adoption of the long-term No-tillage favors the biodiversity of the soil fauna in relation to the soil that has been undergoing two years of cultivation and four annual harrows since 1976. The most representative edaphic taxon in the April/2013 were Acari, Collembola and Diptera, and in the January/2014 they were Acari, Collembola, Hymenoptera and Larva of Lepidoptera. The phytosanitary management of the areas influence the diversity indexes of the edaphic fauna. The soil moisture abiotic factor acts severely under the edaphic fauna, being more evident in the conventional cropping system. The collection season conditioned to the abiotic factors -soil moisture and temperature -influences the density of individuals, species richness and the Shannon and Pielou indexes.

“…Essa diferença pode ser explicada pelo grande número de ácaros e colêmbolos, especialmente os da subordem Poduromorpha (Tabela 3). Esses grupos respondem em curto prazo à maior presença de serapilheira sobre o solo (SCORIZA et al, 2015).…”

“…Nesta pesquisa, este grupo foi somente observado em 5 amostras, sendo 4 na época seca e 1 na chuvosa, todas na Mt, o que reforça o estádio inicial de sucessão ecológica das demais áreas. Os predadores, por serem animais do topo da cadeia alimentar, podem expressar o equilíbrio de um ecossistema, já que para surgirem é preciso haver toda a cadeia anterior a ele estruturada (SCORIZA et al, 2015). No entanto, as áreas do pasto próximo ao SAF tiveram, nas duas épocas, as maiores médias de predadores (Tabela 3).…”

Com a nova legislação ambiental brasileira vislumbra-se a possibilidade do uso de sistemas agroflorestais diversificados para recompor áreas de preservação permanente e reserva legal, principalmente em pequenas propriedades rurais. Uma pergunta que surge, diz respeito a capacidade desses sistemas em reduzir custos na restauração florestal e ao mesmo tempo apresentar eficiência ecológica similar aos plantios em que se faz uso exclusivo de espécies nativas do bioma em questão. Buscando a resposta avaliou-se nesse estudo um sistema agroflorestal implantado em 2005, em Seropédica, RJ, que tinha o objetivo de interligar dois fragmentos florestais ali existentes. Desde então foram feitas uma série de avaliações sobre a eficácia ecológica desse “corredor agroflorestal” na interligação desses fragmentos. Os resultados indicaram que a quantidade e a qualidade da fauna do solo e fungos micorrízicos foram favorecidos pelo sistema agroflorestal em comparação à matriz de pastagem, mas ainda se encontram em níveis inferiores aos fragmentos florestais interligados. A pastagem próxima ao sistema agroflorestal vem se beneficiando da melhoria ambiental ali existente, criando um “efeito de borda positivo”, situação bem distinta da pastagem que se encontrava mais distante da área de influência do corredor agroflorestal. Para os indicadores utilizados, o sistema agroflorestal foi eficiente.

“…Probably the range of properties of the selected field soils was too narrow to identify clearly their influence on toxicity. Scoriza et al (2015) studied the effects of the herbicide mesotrione which is used in forest restoration in Southern Brazil. Methodically, a combination of field experiments, focusing on soil arthropods, and laboratory tests with E. crypticus was used.…”

Enchytraeidae (Oligochaeta, Annelida) are often considered to be typical forestliving organisms, but they are regularly found in agroecosystems of the temperate regions of the world. Although less known than their larger relatives, the earthworms, these saprophagous organisms play similar roles in agricultural soils (but at a smaller scale), e.g., influencing soil structure and organic matter dynamics via microbial communities, and having a central place in soil food webs. Their diversity is rarely studied or often underestimated due to difficulties in distinguishing the species. New genetic techniques reveal that even in anthropogenically highly influenced soils, more than 10 species per site can be found. Because of their close contact with the soil pore water, a high ingestion rate and a thin cuticle, they often react very sensitively to a broad range of pesticides. Firstly we provide a short overview of the diversity and abundance of enchytraeid communities in agroecosystems. Afterwards, we explore the available data on enchytraeid sensitivity toward pesticides at different levels of biological organization, focusing on pesticides used in (mainly) European agroecosystems. Starting with non-standardized studies on the effects of pesticides on the sub-individual level, we compile the results of standard laboratory tests performed following OECD and ISO guidelines as well as those of higher-tier studies (i.e., semi-field and field tests). The number of comparable test data is still limited, because tests with enchytraeids are not a regulatory requirement in the European Union. While focusing on the effects of pesticides, attention is also given to their interactions with environmental stressors (e.g., climate change). In conclusion, we recommend to increase the use of enchytraeids in pesticide risk assessment because of their diversity and functional importance as well as their increasingly simplified use in (mostly standardized) tests at all levels of biological organization.
