| Abstract | Mammals of the piedmont of Yungas in the Alta Cuenca del Rio Bermejo in Argentina: A diversity base-line. Yungas forests harbor a great part of the biodiversity in Argentina, being the Alta Cuenca del Rio Bermejo (ACRB) a high-priority area for conservation. Because many of Yungas mammals have suffered retractions of their distri- bution, studies about their diversity and population status are essential. We report results of rapid biodiversity assessments for 22 localities of Yungas premontane forest of the ACRB. We describe the community composition for all taxonomic groups of mammals and we estimated, for micromammals, species richness, dominance and relative abundance. We documented 74 species of mammals for the ACRB. The species richness and domi- nance were 27.5 (Chao 1 estimator, S*) and 0.47 (Simpson index, D) for bats, and 17 (S*) and 0.24 (D) for non volant mammals. Sturnira lilium, Akodon simulator and Euryoryzomys legatus were notably more abundant than other species. Ten species were caught exclu- sively in the dry season and eight during the wet season. Species richness and dominance for both species groups were very similar among seasons. For bats we observed one species (Lasiurus blossevillii) with a higher relative abundance during the humid season but we do not register differences for non volant micromammals. |
