AGUIAR, Pedro Lopes; SOUZA, Raphael Felipe; OLIVEIRA, Eduardo Borges de  y  NALI, Renato Christensen. Male aggressiveness in the tree frog Dendropsophus branneri (Anura, Hylidae): Physical combat, fighting call, and escalated behavior. Caldasia [online]. 2022, vol.44, n.1, pp.203-207.  Epub 29-Abr-2022. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v44n1.88112.

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.

Palabras clave : Aggressive call; agonistic interaction; Atlantic Forest; graded behavior.
