Fauna Edáfica Na Dinâmica Sucessional Da Mata Atlântica Em Floresta Estacional Semidecidual Na Bacia Do Rio Paraíba Do Sul - Rj

Abstract: RESUMOA fauna edáfica, pela sua diversidade e magnitude das funções que realiza no ambiente solo, pode refletir o estado de funcionamento dos ecossistemas. Neste sentido, este estudo teve como objetivo avaliar a atividade, composição estrutural e diversidade da comunidade da fauna do solo, em diferentes estádios sucessionais da Mata Atlântica, em Pinheiral -RJ. Para tanto, foram estudadas três áreas de Floresta Estacional Semidecidual Submontana em diferentes estádios sucessionais: Floresta em Estádio Inicial … Show more

“…The AFS-2 showed a decline in the abundance of individuals, but was able to maintain the group richness and increase the evenness index throughout the study period. This is the expected pattern for a biological community throughout ecological succession (Machado et al, 2015). The AFS-1 remained very close to the forest in both seasons on the principal response curves, indicating that variations in the composition of soil fauna groups in these two areas showed the same trend.…”

“…A number of researchers have reported on the relationship of SM to the diversity and density of the fauna (CUNHA-NETO et al 2012;ABREU et al 2014;GARLET et al 2015). Machado et al (2015) reported the highest number of organisms during periods of higher rainfall, but when they investigated the edaphic fauna in a fragment of the Semideciduous Seasonal Forest in Rio de Janeiro, they found fewer faunal representatives in the dry season, as it also was found in this inquire. In fact, in March/2013 that preceded the collections, the second highest rainfall value was recorded in Pato Branco / PR (Figure 1), which effectively contributed to the highest values of fauna obtained.…”

“…Segundo Silva et al (2012), na região do Médio Vale do Paraíba do Sul, RJ, com o ciclo do café e a ocupação imobiliária, houve intensas transformações da paisagem e degradação do solo. Em algumas áreas de cafezais abandonados, depois usados com pastagens em diferentes condições de degradação, hoje se observa a floresta secundária em estágio avançado de regeneração (Machado et al, 2015). A classe de pastagem vigorosa (manejada) corresponde a 20,93 e 18,14% da área total (imagem corrigida e sem correção, respectivamente) e ocorre, principalmente, nas terras para criação de gado de leite do IFRJ Campus Nilo Peçanha, Pinheiral, nas planícies aluviais do Rio Paraíba do Sul e margens do ribeirão Cachimbal, além de várzeas em vales fechados com maior umidade.…”
