Factors Affecting Interspecific Aggression in a Year-Round Territorial Species, the Jewel Damselfish

2012

Vertebrates live in complex species networks in which interspecific interactions are common. In some contexts, the aggressive behaviours shown in these interspecific interactions are very similar to those shown in intraspecific interactions. It is still an open question whether intra- and interspecific aggression share common causality. We studied a year-round territorial species the jewel damselfish, (Plectroglyphidodon lacrymatus), which cultivate algae they feed on. Territory holders aggressively defend these algae that are an attractive resource for many other species. In this study, we recorded territorial aggression in free-living individuals and recorded aggressive responses to a sta…
