Snakes of the Municipality of Viçosa, Atlantic Forest of Southeastern Brazil

Abstract

Based on specimens housed in scientific collections, we present here a list of snake species from the Municipality of Viçosa, which is located in an Atlantic Forest portion of the State of Minas Gerais, Southeastern Brazil. Thirty four species were confirmed in Viçosa. Two others have uncertain reports and five that were registered in neighboring municipalities could also occur in Viçosa. Information concerning snakes distribution and natural history is also presented, based on scientific literature data and sporadic field observations in the study area. In general, we can consider that the snake fauna of Viçosa is comprised of species which are able to use environments modified by human action, though some of them are dependent on the remaining forest fragments. Fieldwork is still required to improve the knowledge of snake species richness in forest fragments, to confirm the presence of species with uncertain records and potential occurrence in Viçosa, and to investigate the possibility of population declines of those species without records from the last decade.
