Differing responses to landscape change: implications for small mammal assemblages in forest fragments

摘要: Human modification of landscapes typically results in many species being confined to small, isolated and degraded habitat fragments. While fragment size isolation underpin studies modified landscapes, vegetation characteristics are less frequently incorporated. The relative influence biogeographic (e.g. size, isolation) parameters on assemblages is poorly understood, but critical for conservation management. In this study, a multiple hypothesis testing framework was used determine the importance explaining occurrence an assemblage small mammals 48 forest fragments agricultural landscape south-eastern Australia. Fragment were consistently important predictors across species. contrast, just one native Differing abilities move through provide reasonable explanation these results. We conclude that effective assemblages, it to: (1) consider differing responses change, (2) beyond focus primarily spatial attributes (size, recognise change also has profound effects composition quality.
