Cantos de anúncio e de combate de Centrolene lynchi (Anura: Centrolenidae), com notas sobre seu comportamento de combate e reprodutivo

We describe the advertisement and combat calls, combat behavior, and reproductive behavior of the glass frog Centrolene lynchi, an endemic species of the cloud forests of Ecuador. The typical advertisement call consists of a tonal note and 1-3 peaked notes, each with 1-3 pulses. Variations on this advertisement call include the addition of a short note before the tonal note, as well as the absence of the tonal note. These modifications may be similar to the described call modifications of other anurans in response to the presence of conspecific females and males, potential predators and/or changes in the sound environment. Additionally, we describe the combat call emitted during previously undescribed venter-to-venter combat between males. The discovery of this combat behavior is consistent with the hypothesis that venter-to-venter combat behavior is a shared derived trait of the subfamily Centroleninae. Finally, we describe male reproductive habits and development of the species, including egg attendance by males and implied male parental care.
