Small mammals and microhabitat selection in forest fragments in the transition zone between Atlantic Forest and Pampa biome
Abstract Natural resources are depleted in fragmented landscapes that have their vegetation also altered. As a result, the microhabitat diversity and the composition and distribution of local species are affected. In this study, we evaluated the small mammals’ community diversity, composition and mi...
