Impact of habitat alteration on amphibian diversity and species composition in a lowland tropical rainforest in Northeastern Leyte, Philippines

摘要: The impact of anthropogenic habitat alteration on amphibians was investigated, employing an investigative focus leaf-litter and semi-aquatic species across different types. types which include primary forest, selectively logged secondary abandoned farm areas pasture (this represents a gradient ranging from least altered to most altered, respectively) also encompass two types: stream terrestrial. Species assemblage compared between types, where total 360 were observed (15 species, 6 families). It found that amphibian abundance significantly higher in both forest habitat, richness did not differ with respect type. determined, however, highly dependent type (significantly habitat). Meanwhile, diversity (Shannon–Wiener) composition differed markedly for strip plots. Forest exhibited domination by specialist while (abandoned pasture) open-habitat species. Additionally, strong relationships abundance, as well (within the measured structures microclimatic conditions). Analyses determined best explained DBH (1.3 m ground) lower temperature understorey density. associated increasing density, tree density temperature. In general, lowland tropical rainforest northeastern Leyte affected alteration, highlighting on-going importance conservation efforts.
