Abstract

From 2010 to 2019, we studied the composition of species and habitat use of amphibians in Santa Maria Natural Reserve (RNRSM) and its surroundings. We made active search combining auditive search and visual encounters surveys. Additionally, for 12 months, we installed 14 pitfall traps in seven representative sectors of three environments. We recorded 39 species belonging to 18 genera and seven families; 36 of them were encountered inside the reserve and three in the surroundings. All species were recorded by active search, but only 20 species were recorded in pitfall traps. Grasslands and wetlands were the richest and most similar habitats in the species composition. The semipermanent water bodies were the most used by amphibians, and semipermanent and temporary water bodies have shown similar species composition. We detected six species prioritized for their conservation using an index based on their threats category, distribution and degree of endemism, body size, reproductive potential, ecological rarity, abundance, human threats, and taxonomic singularity. The RNRSM protect 65% of amphibian’s fauna known in Corrientes province and 22.3% of Argentina, conserving habitats strongly affected by Yacyretá Dam, with high biodiversity value. This inventory is a baseline for monitoring the reserve's amphibians. [ABSTRACT FROM AUTHOR]
