Abstract:
Species diversity is a central issue in both community ecology and conservation biology and diet analysis of Tyto furcata has proven to be a tool of high methodological value in determining the presence and distribution of micromammals. The objective of this work is to present the diversity, composition and relative abundance of the species that conform the assembly of micromammals in four environments in the south of Santa Fe province, Argentina. It was obtained a total of 8132 prey recovered from 3442 pellets. From the results obtained, it was possible to establish a specific richness (S) for the study area of 20 species of micromammals, among them four species of sigmodontine rodents not documented for the study area: Oligoryzomys nigripes, Calomys venustus, Holochilus chacarius and Graomys chacoensis. This work shows that although the ansembly of micromammals is typical of the Pampean ecoregion, the most complex (vertical variation) and heterogeneous (horizontal variation) environments that are still preserved present species diversity, since they contain greater diversity of microhabitats.
