Individual consistency in the behaviors of newly-settled reef fish.

摘要: Flexibility in behavior is advantageous for organisms that transition between stages of a complex life history. However, various constraints can set limits on plasticity, giving rise to the existence personalities have associated costs and benefits. Here, we document field laboratory experiment examines consistency measures boldness, activity, aggressive young tropical reef fish, Pomacentrus amboinensis (Pomacentridae) immediately following their pelagic larval benthic juvenile habitats. Newly-settled fish were observed aquaria replicated patches natural habitat cleared resident fishes. Seven behavioral traits representing aspects activity aggression monitored directly via video camera over short (minutes), medium (hours), long (3 days) time scales. With exception aggression, these behaviors found be moderately or highly consistent all scales both settings, implying show stable within settings. Our study first examine temporal constancy settings at critically important phase during cycle fish.
