Rapid inventory of anuran species in a national park of the Brazilian Amazon

The present study conducted a rapid inventory of anuran fauna in the Montanhas do Tumucumaque National Park, in the Brazilian Amazon. The research was motivated by the need to expand knowledge about local biodiversity and support the development of conservation strategies. To achieve this, two sampling campaigns were carried out using the active/visual search method along four pre-established trails. Specimens were identified based on specialized references, and the data were analyzed in terms of abundance, species richness, and spatial distribution patterns. A total of 30 species belonging to nine families were recorded, increasing the known number of species in the area to 66. The Hylidae family exhibited the highest richness and abundance. The spatial distribution of anurans revealed an aggregated pattern, suggesting that resource availability influences their distribution. Most species were recorded during the nighttime, corroborating patterns previously described for tropical anurans. The results indicate that PARNA Tumucumaque harbors a rich diversity of anurans, highlighting its importance for the conservation of Amazonian herpetofauna and biodiversity.
