Anurans of a disturbed area in Jarú, Rondônia, Brazil

Abstract

This paper presents a checklist of anurans species and their distribution in a disturbed area in the municipality of Jarú, Rondônia state, Brazil. Nineteen species belonging to eight families were sampled with pitfall traps and time constrained searches. About 70% of the species were found in a secondary forest and 40% were found only in this environment, while about 57% were found in pastures, with 26% of species being registered only in this habitat. Our results were similar to those of previous studies in other disturbed areas of Rondônia. Species that can be found in different habits were unevenly distributed, with forested environments harboring more species. Despite its nearness to Cerrado and the large number of open areas available, most species found are typical of the Amazon forest.
