Abstract

SERRANO, José M.. The advertisement call of the endemic frog from the Pedregal in Mexico City. Rev. Mex. Biodiv. [online]. 2016, vol.87, n.2, pp.535-539. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2016.03.003.

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.
