Reptiles and amphibians of a poorly known region in southwest Amazonia

Resumo


The Amazon is the largest tropical forest of the world and it is extremely rich in biodiversity. However, some portions of the biome are still poorly known. This work presents an inventory of the herpetofauna of Boca do Acre municipality, a still preserved region located in southwest Amazonas state. The inventory was carried out in two periods, a sampling during the middle of the rainy season and another one at the end of the rains. Diverse survey methods were employed, such as pitfall traps, diurnal and nocturnal visual searches, car searches on the BR 317 highway, and opportunistic registrations. We recorded 56 amphibians and 53 reptiles during the field work. We captured 27 species in pitfall traps, and 38 were found along the BR 317, alive or dead on the road, being snakes principally affected by road-kills. The species accumulation curves did not reach stability, indicating that the inventory was not complete. Our results show the high species richness of this region, its importance for the Amazonian biodiversity, and the urgency of its preservation.
