Explorando as Boana: atualização da distribuição geográfica de Boana crepitans e comunicação e seleção de sítio de vocalização em Boana stenocephala

Abstract

New discoveries about the geographic distribution of Boana crepitans have revealed the first confirmed record of the species in the state of São Paulo, specifically in the region of Cajati. During field expeditions, individuals were found in open, anthropized areas near fragments of secondary forest. A literature review showed the absence of previous records with voucher material for São Paulo, highlighting the significance of this finding and suggesting a broader distribution for the species than previously known. Additionally, it raises questions about the presence of B. crepitans in Mato Grosso do Sul, where no valid records were found. Complementary studies on the natural history and population biology of amphibians, such as those conducted with Boana stenocephala in the Serra da Canastra National Park, contribute to a better understanding of habitat use and reproductive behavior. Evaluations of male calling site selection in this species indicated that body length (snout-vent length) does not influence the choice of these sites. Furthermore, it was observed that lower limb movements are a common visual display among males, suggesting a form of communication between males and females during the reproductive period. These studies reveal important gaps in knowledge about the distribution and behavior of species in the Boana genus.
