متن کاملAlarm Calls
Animals commonly vocalize when threatened by a predator. These signals, usually termed alarm calls (from old Italian all arme ‘to arms’ on the approach of an enemy), have continued to bewilder and fascinate for a number of reasons, the first of which is mainly practical. In animal research, it is often difficult to break down the continuous behavioral stream into discrete and meaningful units, ...
متن کاملPredation increases acoustic complexity in primate alarm calls.
According to most accounts, alarm calling in non-human primates is a biologically hardwired behaviour with signallers having little control over the acoustic structure of their calls. In this study, we compared the alarm calling behaviour of two adjacent populations of Diana monkeys at Taï forest (Ivory Coast) and Tiwai Island (Sierra Leone), which differ significantly in predation pressure. At...
متن کاملEvolving communicative complexity: insights from rodents and beyond.
Social living goes hand in hand with communication, but the details of this relationship are rarely simple. Complex communication may be described by attributes as diverse as a species' entire repertoire, signallers' individualistic signatures, or complex acoustic phenomena within single calls. Similarly, attributes of social complexity are diverse and may include group size, social role divers...
متن کاملIs sociality required for the evolution of communicative complexity? Evidence weighed against alternative hypotheses in diverse taxonomic groups.
Complex social communication is expected to evolve whenever animals engage in many and varied social interactions; that is, sociality should promote communicative complexity. Yet, informal comparisons among phylogenetically independent taxonomic groups seem to cast doubt on the putative role of social factors in the evolution of complex communication. Here, we provide a formal test of the socia...
