Descripción preliminar de las llamadas de anuncio de Eleutherodactylus patriciae (Anura: Eleutherodactylidae), en el Parque Nacional Valle Nuevo, República Dominicana

Abstract

Most of the Hispaniolan species of the genus Eleutherodactylus lack quantitative descriptions of their advertisement calls. Among such species is E. patriciae, an endemic frog of the Central Cordillera of which there was only an onomatopoeic reference of its vocalizations. We recorded 8 males of E. patriciae in two savannas covered by “pajón” (Danthonia domingensis) in the Valle Nuevo National Park. For each call, we measure seven temporal variables and two spectral variables in 20 respective calls. Advertisement calls are whistles with 0.4 seconds mean duration, a mean repetition rate of 16.6 signals / minute, and a mean dominant frequency of 2.1 kHz. Each call has a harmonic structure that extends to the ultrasonic spectral range (˃20 kHz).
