The advertisement call of Dendropsophus novaisi (Bokermann, 1968) (Anura: Hylidae: Dendropsophinae)

Abstract

Dendropsophus novaisi (Bokermann,1968) was described from Maracás Municipality, State of Bahia, Brazil. Since its description, the species has been reported for one additional location in the State of Minas Gerais (Pedra Azul - Gomes & Peixoto 1996; Peixoto & Pimenta 2004) and five additional locations in Bahia (Boa Nova, Jequié, Jeremoabo, Camacan and Pau Brasil - Gomes & Peixoto 1996; Santos-Silva et al. 2012; Silva et al. 2013; Dias et al. 2014). However, information is still scarce about reproductive, ecological and acoustic characteristics of this treefrog. Here, we describe the advertisement call of D. novaisi and provide the geographic record of a new population.

Individual variation in advertisement calls of the pale-shouldered horned toad (Xenophrys boettgeri)

“…Of these, advertisement calls have been widely studied because they characterize species-specific courtship signals (Chuang et al 2016;Da Veiga Teixeira et al 2016;Galvis et al 2016;Modak et al 2016;Serrano 2016;Bosch et al 2017). Male anurans emit a unique advertisement call to enable females to identify and evaluate conspecific males (Grenat et al 2013;Twomey et al 2015;Protázio et al 2017), and female anurans often decide what male to mate based on the quality and structure of these calls (Pröhl 2003;Yu and Zheng 2009;Welch et al 2014). Generally, males who produce calls of lower frequencies, higher rates, longer durations, greater intensities, and greater complexity are more favorable as mates (Bee et al 1999;Pröhl 2003;Morais et al 2012;Batista et al 2015).…”
