“…A large number of Acari species is ecologically sensitive to environmental disturbances (DUARTE, 2004;PARISI et al, 2005;SGARDELIS & USHER, 1994). In this work we found that higher Acari densities at the studied taxonomic group level were related to regenerating environmental conditions, (e.g., undisturbed grassland field and disturbed edge) but not to highly disturbed areas (disturbed grassland field).…”

ABSTRACT. Soil invertebrate distribution in Araucaria forest, grassland and edge habitats was studied in both disturbed and undisturbed areas in southern Brazil. Mean-density and taxa compositions were verified. Invertebrate densities differed between grassland and the other two habitats in the undisturbed area but not across the disturbed one. At the disturbed area taxa differed between the grassland and the other two habitats. The undisturbed area, on the other hand, presented taxa differences only between the grassland and the forest habitats. Acari, Arachnida and Collembola were the most sensitive taxa for detecting differences across habitats in both areas. At the disturbed area, these taxa presented densities lowering from the forest to the grassland. At the undisturbed area the same taxa increased from the forest to the grassland. Coleoptera and Formicidae (Insecta) presented no difference between habitats at the studied taxonomic level. KEYWORDS.Araucaria forest, forest edge, grasslands, Acari, Collembola.RESUMO. Invertebrados de solo no mosaico floresta com Araucaria -campos no sul do Brasil: diferenças entre áreas impactadas e não impactadas. A distribuição dos invertebrados de solo entre os em ambientes de floresta com Araucaria, borda-demata e campo, foi analisada em duas áreas no sul do Brasil: uma reserva ecológica e uma propriedade agrícola. A densidade média e a composição dos principais taxa foram verificadas. A densidade total de invertebrados diferiu entre o campo e os outros dois hábitats na área protegida, mas não na fazenda. A composição dos taxa diferiu entre o hábitat de campo e os outros dois habitats na fazenda, e entre o campo e a mata com Araucaria na área protegida. Acari, Arachnida e Collembola foram os grupos que mais apresentaram diferenças entre os diferentes habitats. Na área alterada (fazenda), esses grupos apresentaram diminuição na densidade na direção da floresta com Araucária para o campo, enquanto que na área protegida suas densidades foram maiores no campo do que na floresta com Araucária. Coleoptera e Formicidae (Insecta) não apresentaram diferenças significativas no nível taxonômico estudado.

“…This result was obtained comparing larger forest fragments with the smaller ones, such as in areas of Atlantic Rain Forest in the Southern Brazil (DUARTE, 2004) and in the Northeastern Brazil (LEAL et al, 2012) and in the Brazilian Amazonia (VASCONCELOS et al, 2006). The same pattern occurred when comparing native forest fragments of Atlantic Forest with eucalyptus plantations in the state of Rio de Janeiro (CUNHA NETO et al, 2012); and forest fragments with different stages of natural regeneration of Atlantic Forest in the same state (MENEZES et al, 2009;CAMARA et al, 2012).…”

“…2017. Martini, A. et al ISSN eletrônico 1982 10.5380/rf.v47i1.39878 a soil arthropod community with also higher diversity (DUARTE, 2004;MENEZES et al, 2009;CAMARA et al, 2012;CUNHA NETO et al, 2012). In addition, the higher complexity of the soil arthropod community in MF also reflected the fact that this area is connected to some other forest fragments by less than 200m of distance, while the LF is isolated by at least 500m from other forest fragments (GOMES et al, 2010).…”

“…The organisms were quantified and identified in taxonomic groups (order, in general). According to other studies, in this level of identification, it was possible to evaluate the influence of the edge effect (GOEHRING et al, 2002;DUARTE, 2004;PEREIRA et al, 2013), plant richness/diversity, stage of forest regeneration (NEGRETE-YANKELEVICH et al, 2006;MENEZES et al, 2009;CAMARA et al, 2012) or the climatic season (SILVA et al, 2012) on the soil fauna community. Although this approach does not allow the precise determination of the ecological functionality of certain groups, it has less laborious execution, provides a global knowledge of the variety of the organisms present (CORREIA; OLIVEIRA, 2000) and provides a simple indication of the ecological complexity of the soil fauna community (STORK; EGGLETON, 1992).…”

Forest fragmentation may influence the soil fauna community. This study aimed to test the hypothesis that exists differences in the structure and composition of the soil arthropod communities among three Atlantic Rain Forest fragments with different sizes (SF: small; MF: medium and LF: large fragment) in Teresópolis, Rio de Janeiro, Brazil. The sample of the organisms occurred by means of random stratified installation of pitfall traps, during the rainy and dry seasons. The organisms were identified in taxonomic groups (mainly in order). The tested hypothesis was corroborated because the soil arthropod communities with more complex structure occurred in the MF (higher values of evenness and diversity) and in the LF (higher richness), which presented more similarity to each other, in comparison to the SF (higher total abundance). Collembola, Coleoptera, Chilopoda, Hymenoptera, Enchytraeidae and Blattodea featured the MF and the LF, whereas the SF favored Formicidae. Keywords: Biodiversity; edge effect; forest fragmentation; soil fauna; tropical forests. ResumoEfeito do tamanho de fragmentos de Mata Atlântica sobre a estrutura e composição da comunidade de artrópodes do solo, RJ, Brasil. A fragmentação florestal pode influenciar a comunidade da fauna do solo. Este trabalho objetivou testar a hipótese de que existe diferença na estrutura e composição das comunidades de artrópodes do solo entre três fragmentos de Mata Atlântica com diferentes tamanhos (FP: fragmento pequeno; FM: fragmento médio; FG: fragmento grande) em Teresópolis, Rio de Janeiro, Brasil. A amostragem de organismos ocorreu por meio de armadilhas de queda instaladas de maneira aleatória estratificada, nas estações chuvosa e seca. Os organismos foram identificados em grupos taxonômicos (ordem, principalmente). A hipótese testada foi corroborada, uma vez que a comunidade de artrópodes do solo com estrutura mais complexa ocorreu no FM (maiores valores de uniformidade e diversidade) e no FG (maior riqueza), os quais apresentaram maior similaridade entre si, em comparação com o FP (maior abundância total). Collembola, Coleoptera, Chilopoda, Hymenoptera, Enchytraeidae e Blattodea caracterizaram o FM e o FG, enquanto que o FP favoreceu Formicidae. Palavras-chave: Biodiversidade; efeito de borda; fragmentação florestal; fauna do solo; florestas tropicais.

“…However, much of the natural areas have transferred due to human activities. The potential for arthropods as indicators is especially promising in the case of the Atlantic Forest, for which scarce available data exist (Duarte, 2004;Baretta et al, 2008), despite this biome's status as a conservation hotspot (Myers et al, 2000), and the important pressure to the development of agro-forestry systems, which includes the replacement of native forests by Eucalypt plantations DOI: http://dx.doi.org/10. 22192/ijarbs.2017.04.11.011 for industrial use (Lima, 1996).…”

India is one of the twelve mega biodiversity in the world and the Western Ghats in Southern India are considered to be one of the 18 hotspots of biodiversity in the world. The natural areas of Nilgiris has been Shrunk by exotic tree plantation like Eucalyptus and Wattle. Recent researches have sought that more litter mass provides food and habitat for soil micro-arthropods. The period of the study was from March to August 2014. During litter decomposition nutrients like N, P and K release into the soil. But invasive species like Eucalyptus and Wattles of the area have given negative effects to the soil nutrients. So the environmental term illustrates the variation in soil fertility and decreases NPK. The comparative diversity of micro-arthropods in natural, Wattle and Eucalyptus plantations was studied in Nilgiris. Moreover, Eucalyptus and Wattle plantations decreased the availability of ground water consequently affecting the soil fertility. Hence the present study suggests minimizing the growth of Wattle and Eucalyptus plantations in the natural areas which may help to maintain the fertility of the soil.
