Velásquez, Nelson A.; Marambio, Jesús; Brunetti, Enzo; Méndez, Marco; Vásquez Salfate, Rodrigo; Penna Varela, Mario (The Linnean Society of London, 2013)The study of intraspecific variation of acoustic signals and its relationship with genetic divergence is important for understanding the origin of divergence in communication systems. We studied geographical variation in ...

Penna Varela, Mario; Velásquez, Nelson A.; Bosch, Jaime (Wiley-Blackwell, 2015)The auditory sensitivity in three species of the anuran genus Alytes (Alytidae) was examined to determine patterns of intra- and interspecific variation, relating these measurements to behavioural preferences measured in ...

Velásquez, Nelson A.; Opazo, Daniel; Díaz, Javier; Penna Varela, Mario (PLOS One, 2014)Divergence of acoustic signals in a geographic scale results from diverse evolutionary forces acting in parallel and affecting directly inter-male vocal interactions among disjunct populations. Pleurodema thaul is a frog ...

Rojas, Valentina; Labra, Antonieta; Valdés Guerrero, José Luis; Velásquez, Nelson A. (Pensoft, 2021)Among amphibians, conspecific chemical communication has been widely studied in Caudata. Adult anurans, by contrast, have received less attention. Recently, it was shown that chemical scents are also relevant for adult ...

Moreno Gómez, Felipe; León, Alex; Velásquez, Nelson A.; Penna Varela, Mario; Délano, Paul H. (Acoustical Soc. Amer., 2015)Animals obtain information about their social environment by means of communication signals, which provide relevant subtle cues for individual recognition. An important requisite for this process is the existence of ...

Velásquez, Nelson A.; Valdés, José Luis; Vásquez Salfate, Rodrigo; Penna Varela, Mario (Elsevier, 2015)Sexual selection is one of the main evolutionary forces that drive signal evolution. In previous studies, we have found out that males of Pleurodema thaul, a frog with an extensive latitudinal distribution in Chile, emits ...
