El canto de anuncio de la rana endémica del Pedregal de la ciudad de Méx

Abstract

In this study the advertisement call of the frog Eleutherodactylus grandis from the population of the Ecological Reserve Pedregal de San Angel is described. This call consists in a short whistle without modulated frequency and a notorious amplitude modulation. It was found that advertisement calls have scarce or no individual variation in their dominant frequency, which suggest that E. grandis has a spectral signature a distinctive spectral frequency within the population- that could be involved in individual recognition.
