Male aggressiveness in the tree frog Dendropsophus branneri (Anura, Hylidae): Physical combat, fighting call, and escalated behavior

Herein we describe a male-male fight of the tree frog Dendropsophus branneri, as well as the vocalizations emitted during this behavior (fighting call). Our observations also suggest an escalated aggressive behavior for the species. These behaviors are poorly reported in the diverse genus Dendropsop...

Zusammenfassung:Herein we describe a male-male fight of the tree frog Dendropsophus branneri, as well as the vocalizations emitted during this behavior (fighting call). Our observations also suggest an escalated aggressive behavior for the species. These behaviors are poorly reported in the diverse genus Dendropsophus and will aid in future studies on anuran aggressiveness. Describimos un combate entre machos de la rana arborícola Dendropsophus branneri, así como el tipo de vocalización emitido durante este comportamiento (canto de combate). Nuestras observaciones sugieren un comportamiento agresivo escalado para esta especie. Estos comportamientos han sido poco reportados en un género tan diverso como Dendropsophus y ayudarán en futuros estudios de agresividad en Anura.
