Filling the knowledge gaps of Paratelmatobius mantiqueira (Anura: Leptodactylidae): tadpole, acoustic repertoire, and life history traits

ABSTRACT

We monitored a recently discovered population of Paratelmatobius mantiqueira for 13 months and gathered new data for the species: external morphology of tadpoles, acoustic repertoire, and life history traits. We also collected unprecedented data on behaviours and interactions of adults and tadpoles observed during monitoring. Based on natural markings of P. mantiqueira adults, we estimated the effective population size and estimated their home range. With circular statistics, we tested whether they were seasonally active and evaluated how humidity and temperature influenced the detectability of the species. We found that tadpoles and advertisement calls of P. mantiqueira differed from congeneric species. We also described the release and aggressive calls. We found that the species has a small home range, with probable resident females. Temperature and humidity positively influenced the detectability of P. mantiqueira; encounters varied seasonally. Paratelmatobius mantiqueira is a strictly forest species, found mainly in leaf litter and associated with muddy areas in rocky outcrops of highland forests. Our study provides new data about P. mantiqueira, which may help future integrative taxonomy approaches and contribute to the conservation of this species.
