The Choco-Darien rainforest harbour about 350 amphibian species, of which 210 (60%) are endemic. It is located in the most north-western region of South America, including part of the Isthmus of Panama and mainly wet and montane tropical forests of eastern Panama and Pacific slope of Colombia and north-western Ecuador. However, this large diversity is threatened by human activities such as mining, natural resources exploitation and land transformation, all of which have significant consequences on water quality and therefore on the associated amphibian diversity. The amphibian vocalizations have been widely used in non-visual surveys becoming an important tool for monitoring biodiversity. Bioacoustic monitoring represents an excellent strategy for identifying the composition of anurans in a community. However, the advertisement call description is lacking for many amphibian species (especially for glass frogs). Such information is of great importance for ecosystem conservation, considering the role of these species as bioindicators of water quality, regulators of ecosystem services by diseases control and for ecosystem services by nutrient cycling.
The objective of this project is to characterize acoustic calls of glass frog species inhabiting the Chocoan rainforest. The surveys will be made in multiple localities along the distribution of glass frogs in the Chocoan rainforest. We will describe the spectral features of glass frog calls and we will record the environmental and biotic conditions where these species occur. The surveys will be made in four localities along the distribution of glass frogs in the Chocoan rainforest in Colombia. Each locality will be visited once during the rainy season. On each field trip we expected to obtain information about the number of glass frog species (species richness), together with acoustic records of the species available.
