fauna of medium and large sized in the RPPN of UNISC, RS, Brazil. Biota neotrop., 9(4): http://www.biotaneotropica.org.br/v9n4/en/abstract?inventory+bn02109042009.Abstract: The aim of this study was to conduct an inventory on the mammal fauna present at UNISC's private natural reserve (RPPN), in order to better contribute with data on the occurrence and distribution of mid and large-sized mammal species at Rio Grande do Sul's Serra Geral region. Field samplings were conducted from November 2008 to April 2009. Additional previously collected data were also used. Methods used were live visual searching and camera-traps. Records of 16 mammal species were obtained, belonging to 12 families and six Orders: two Didelphimorphia, one Xenarthra, two Primates, six Carnivora, one Artiodactyla and four Rodentia. Two other species were not recorded according to our survey protocols and, consequently, were not considered in the analysis of occurrence consistency and spatial occupation. Six species were considered as occasional, seven were accessory, and only one, Cerdocyon thous, was constant. Nine species (64%) were considered as specialists regarding the habitats they occupied, and five (36%) were generalists. Diet categories analysis indicated seven omnivorous species (43.75%), four frugivorous (25%), three carnivores (18.75%) and two herbivorous (12.5%). Among the 16 species recorded, seven are classified as under any level of threat of extinction for the State of Rio Grande do Sul, one is nationally threatened, and two other are considered globally "near threatened". The fact that 44% of the species are experiencing any level of extinction threat reinforces the importance of the RPPN for the conservation of the regional mammal fauna. de médio e grande porte na RPPN da UNISC, RS, Brasil. Biota neotrop., 9(4): http://www.biotaneotropica.org.br/v9n4/pt/abstract?inventory+bn02109042009.Resumo: Buscou-se com este trabalho inventariar a mastofauna da RPPN da UNISC, contribuindo com dados a respeito da ocorrência e distribuição de espécies de mamíferos de médio e grande porte na Região da Serra Geral do Rio Grande do Sul. As amostragens de campo realizaram-se nos meses de novembro de 2008 a abril de 2009, porém, foram acrescentados registros tomados anteriormente. Utilizou-se os métodos de busca visual e de armadilhas fotográficas. Foram obtidos registros de 16 espécies de mamíferos silvestres, pertencentes a 12 famílias e seis ordens: dois Didelphimorphia, um Xenarthra, dois Primates, seis Carnivora, um Artiodactyla e quatro Rodentia. Duas espécies não foram registradas nas amostragens padronizadas, conseqüentemente não submetidas às análises de constância de ocorrência e ocupação espacial. O índice de constância de ocorrência revelou que seis espécies foram consideradas ocasionais, sete acessórias e apenas uma constante, Cerdocyon thous. A análise da ocupação espacial das espécies demonstrou que nove espécies (64%) são especialistas, quanto ao habitat ocupado, e cinco (36%) generalistas. A análise das categorias de dieta evide...
