Abstract

Each animal species selects specific microhabitats for protection, foraging, or micro-climate. To understand the distribution patterns of small mammals on the ground and in the understorey, we investigated the use of microhabitats by small mammals in a deciduous forest of southern Brazil. Ten trap stations with seven capture points were used to sample the following microhabitats: liana, fallen log, ground litter, terrestrial ferns, simple-trunk tree, forked tree, and Piper sp. shrubs. Seven field phases were conducted, each for eight consecutive days, from September 2006 through January 2008. Four species of rodents (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes and Mus musculus) and two species of marsupials (Didelphis albiventris and Gracilinanus microtarsus) were captured. Captured species presented significant differences on their microhabitat use (ANOVA, p = 0.003), particularly between ground and understorey sites. Akodon montensis selected positively terrestrial ferns and trunks, S. angouya selected lianas, D. albiventris selected fallen trunks and Piper sp., and G. microtarsus choose tree trunks and lianas. We demonstrated that the local small-mammal assemblage does select microhabitats, with different types of associations between species and habitats. Besides, there is a strong evidence of habitat selection in order to diminish predation.


Cada espécie animal pode apresentar seletividade por micro-habitats priorizando proteção, forrageio ou microclima. Para compreender os padrões de distribuição de pequenos mamíferos ao nível do solo e de sub-bosque, nós analisamos o uso de micro-habitat por pequenos mamíferos em uma floresta estacional no sul do Brasil. Dez estações amostrais com sete pontos de captura foram usadas para amostragem dos seguintes microhabitats: liana, tronco caído, solo apenas coberto por folhiço, solo coberto por samambaias, árvore com tronco simples, árvore com bifurcações e arbustos do gênero Piper sp.. Sete fases de campo foram executadas durante oito dias consecutivos de setembro de 2006 a janeiro de 2008. Quatro espécies de roedores (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes e Mus musculus) e duas espécies de marsupiais (Didelphis albiventris e Gracilinanus microtarsus) foram capturadas. As espécies capturadas apresentaram diferença significativa quanto ao uso do microhabitat (ANOVA p= 0,003), particularmente entre locais no solo e sub-bosque. Akodon montensis utilizou com maior frequência samambaias terrestres e troncos caídos, S. angouya lianas, D. albiventris troncos caídos e Piper sp. e G. microtarsus árvores e lianas. Nós demonstramos que a comunidade de pequenos mamíferos locais, de fato, apresenta uma seleção de microhabitats, com associações entre a maioria das espécies e habitats. Além disso, há forte indício de seleção de habitat devido à pressão de predação.
