LEVANTAMENTO DE MAMÍFEROS DE MÉDIO E GRANDE PORTE EM ÁREA DE CERRADO, NO OESTE GOIANO.

Abstract

Among the Brazilian fauna, mammals represent approximately 701 species, from which 30% or 210 species are considered endemic in Brazil. From this total are found in the Cerrado 251 species, including 32 endemic from this biome. This work aimed to establish an overview of the taxonomic composition, richness and abundance of the community ofmedium and large-sized mammals in the Cerrado area in the county of Arenopolis State of Goiás Brazil.It was done four (04) sampling campaigns from October - 2009 up to November - 2011, with eight (08) days of effective sampling per campaign, with the use ofthree (03) complementary methods which were, camera-traps, linear transects, diurnal and nocturnal with the use of Sealedbean.In this study were cataloged 23 species distributed in 09 (nine) orders and 16 families, with a total of 169 individuals registered, from which 13 species are in some lists of endangered animals. The species Hydrochoerushydrochaeris was the most frequent during the studies with 14.20% of the records and 24 individuals, followed by Nasuanasua with 11.24 % and 19 specimens, in the side of lower frequency Puma concolor and Puma yagouaroundi had this index reduced to 0.59% each, on the basis of the record of these ones have occurred only once. The richness found in the study area is still incomplete and the results must be more conclusive as new steps of faunal study are performed. The different methods used to obtain the records from medium to large mammals were complementary amongthemselves, which are considered to be of low evasionbased on the non-capture and stress of the animals. From the medium and large-sized mammals cataloged, part is in danger of extinction, even being considered of wide distribution in the Cerrado. However, the achievement of a directed faunal monitoring, mainly to these species, might benefit the mammal species found in the study area, assisting and directing efforts of handling these species.
