Response of dung beetle assemblages to landscape structure in remnant natural and modified habitats in southern Mexico

摘要: .  1 To provide reliable tools for landscape management in tropical regions, it is important to recognise the emergent properties of heterogeneity and understand their influence on different components biodiversity. 2 The effects habitat type, patch size shape, canopy cover, distance between habitats, elevation were examined partitioned diversity (alpha, beta gamma) dung beetles a transformed southern Mexico. 3 In total, 4109 individuals belonging 28 species beetle recorded entire landscape. Alpha was similar among although composition more forest remnants living fences than pastures. Beta related differences habitats. The fragments significantly correlated with mean number captures richness per site. Gamma depended turnover (beta diversity) local richness. 4 In general, pastures trees, small patches retain significant proportion fauna typically associated pristine remaining tracts forest, along contemporary elements may offer suitable habitats future recolonisation by other insect heavily disturbed landscapes Mexico.
