Repeatable Territorial Aggression in a Neotropical Poison Frog

Intra-specific aggressive interactions play a prominent role in the life of many animals. While studies have found evidence for repeatability boldness, activity, and exploration amphibians, we know relatively little about consistent among-individual variation aggressiveness, despite its importance male-male competition territoriality. Amphibians, Neotropical poison frogs (Dendrobatidae) particular, are highly suitable investigating as most species exhibit strong territoriality at least one sexes. In present study, aimed to fill this gap knowledge, by within- between-individual territorial aggression semi-natural population frog Allobates femoralis French Guiana. We conducted repeated, standardized behavioral tests assess if level is within different between individuals. Further, tested possible link body size aggression. moderate but no age and/or size. conclusion, our study represents first documentation repeatable behavior context amphibians.
