| We investigated the richness, composition, and species relative abundance of a terrestrial small mammal community in a Deciduous Forest area in the austral boundary of the Atlantic Forest. The microhabitat use of the most common species was also investigated. Six rodents - Akodon montensis (Thomas, 1913), Oligoryzomys nigripes (Olfers, 1818), Sooretamys angouya (Thomas, 1913), Thaptomys nigrita (Lichtenstein, 1829), Mus musculus (Linnaeus, 1758) and Juliomys sp. - and one marsupial - Didelphis albiventris (Lund, 1840) - were captured. Thaptomys nigrita is recorded in the state of Rio Grande do Sul for the first time. Species richness was poor when compared with communities in the central portions of the Atlantic Forest, but equivalent to that found in the... |
