“…Para a Mata Atlântica, alguns trabalhos já evidenciaram as diferenças de diversidade, composição de espécies e o impacto dos efeitos de borda sobre diferentes componentes do ecossistema decorrentes do processo de fragmentação (São Bernardo & Galetti, 2004;Bianconi et al, 2006;Oliveira Filho et al, 2007). Embora ao menos no plano teórico seja possível traçar paralelos entre a perda de biodiversidade e importantes processos do ecossistema, como, por exemplo, a polinização e a decomposição, o tipo de informação existente na literatura não permite estabelecer essas relações concretamente (Lewis, 2009 (Rantalainen et al, 2004). Na escala da paisagem, o mosaico de tipos de vegetação ou estádios sucessionais também tem efeitos sobre o padrão de diversidade e composição da comunidade edáfica (Chust et al, 2003).…”

“…Works performed by Rantalainen et al (2004) and Chust et al (2003) verified that the mosaic of vegetation types or successional stages can show patterns of diversity and composition of the edaphic community, depending on the quantity and quality of litter in a specific habitat. These invertebrates have a wide variety of size and diameter, which gives them a differentiated hability in their feeding strategy and habitat adaptation (Aquino et al, 2008), which, in turn, can influence the soil processes directly through physical modification of the litter and the soil environment, and indirectly through interactions with the microbial community (Gonzalez et al, 2001).…”

The vegetation physionomy and cover can show patterns of diversity and composition of the edaphic community, depending on the quantity and quality of litter in a specific habitat. The objective of this study was to evaluate the effect of the vegetation gradient formed by Graminoid Field (GRF), Cerrado Sensu Stricto (CSS), Cerradão (CRD) and Semideciduous Seasonal Forest (SSF) on density, diversity and composition of the edaphic fauna community in two seasons of the year, in the Sete Cidades National Park (Piauí state). For fauna sampling, a total of eight pitfall traps, distanced 10 m, were placed in each area in the central part of each system, where they remained for seven days. In the wet period, there was a tendency to increase the number of individuals as a function of the complexity of the vegetation formation, with the inverse occurring in the dry period. It was verified an environmental variation of the climatic factors temperature and humidity according to the vegetal formation, contributing to a heterogeneous distribution of the fauna. The GRF formation presented a significantly lower value of average richness only in the dry period. Regarding the variables of diversity and uniformity, they did not show drastic variations in relation to the vegetation gradient studied. The dominant groups in the vegetation gradient were Formicidae, Coleoptera, Aranae, Acari and Collembola, with reduction of the number of Coleoptera in the dry season. Principal component analysis (PCA) revealed greater differences in the composition of the communities between the vegetation formations for the rainy season. At this time, the formations SSF and CRD were associated to a greater diversity of invertebrates than CSS and GRF, demonstrating the influence of the vegetation complexity on the soil fauna community.Keywords: Savanna, seasonality, species diversity, soil invertebrates, successional stage. Fauna edáfica em um gradiente vegetacional no Parque Nacional de Sete Cidades ResumoA fisionomia e cobertura vegetal podem mostrar padrões de diversidade e composição da comunidade edáfica, em função da quantidade e qualidade da serapilheira em determinado habitat específico. O presente trabalho teve por objetivo avaliar o efeito do gradiente vegetacional formado por Campo Graminóide (CGR), Cerrado Sensu Stricto (CSS), Cerradão (CRD) e Floresta Estacional Semidecídua (FES) sobre a densidade, diversidade e composição da comunidade da fauna edáfica em duas épocas do ano do Parque Nacional de Sete Cidades (PI). Para amostragem da fauna foram colocadas um total de oito armadilhas do tipo Pit-fall, distanciadas por 10 m, em cada área na parte central de cada sistema, onde permaneceram por sete dias. No período úmido houve uma tendência a aumento do número de indivíduos conforme a complexidade da formação vegetal e o inverso ocorreu no período seco. Verificou-se uma variação ambiental dos fatores climáticos temperatura e umidade conforme a formação vegetal contribuindo para uma distribuição heterogênea da fauna. Apenas no período ...

“…The primary mechanisms underpinning the effects of soil biota on plant growth are the mineralisation of plant residues by decomposer organisms and the release of nutrients into the soil in plant-available form, and the capacity of the soil biota to directly assist plants in nutrient uptake. These processes are influenced by soil microbial biomass and composition, which is, in turn, dependent on the amount and quality of inputs of plant litter (Wardle 2002;Rantalainen et al 2004).…”
