1. 1. Gedragsbiologie

   

   A concise, student-oriented introduction to ethology and behavioural biology that explains how animal behaviour is studied and understood, combining proximate mechanisms (neurobiology, hormones, development, learning) with ultimate explanations (function and evolution). It surveys methods and key topics—communication, social organisation, mating systems, aggression, foraging and parental care—using comparative examples (including primates) and empirical studies to show how behaviour arises, adapts and is maintained across species.
