Composição da fauna de mamíferos não voadores presente em um remanescente florestal no munícipio de Ribeirão Bonito, São Paulo

Abstract

The São Paulo State is suffering an urban and rural expansion that has been causing fragmentation and isolation of Cerrado domain in forest remaining. Most of these occupied areas in São Paulo State have put the vertebral animals, mainly the mammals, in danger. The aim of this study was do the mastofauna survey present in a forest fragment with 260 ha located in Ribeirão Bonito municipality in this State, relate this fauna with the vegetation that compose the forest fragment and collect biological data and information about mastofauna conservation. Were performed 33 field visits for the sampling and the methodology consisted in mammals observations and capture. The observations were made by active search, allowing research mammals of medium and large size, and the mammals capture utilized pitfall for small mammals study, both carried out in the period between February 20013 and January 2014. The studied fragment can be classified as a transition area among Cerradão and Semideciduous forest, where were identified 114 plant species. Were identified 16 species of non-flying mammals of various sizes, ranging from small to large, and grouped in 10 families (Didelphidae, Canidae, Felidae, Procyonidae, Dasypodidae, Cricetidae, Hydrochoerinae, Cervidae, Tapiridae and Atelidae) belonging to seven orders (Didelphimorphia, Carnivora, Cingulata, Rodentia, Artiodactyla, Perissodactyla and Primates). Among this species identified in the study area, highlight sensitive species to anthropic pressure like Tapirus terrestris e Lycalopex vetulus. Analysis showed influence of plant species composition and richness in the distribution of small mammals within the forest fragment studied.
