Quality prevails over identity in the sexually selected vocalisations of an ageing mammal

摘要: Background Male sexually selected vocalisations generally contain both individuality and quality cues that are crucial in intra- as well inter-sexual communication. As is a fixed feature whereas male phenotypic changes with age, may be subjected to different selection pressures over time. Individuality (for example, morphology of the vocal apparatus) body size dominance status) can affect production mechanism, inducing same components convey kinds information. In this case, do quality-related acoustic structure calls induce modification identity from year year? We investigated question fallow deer (Dama dama), which some parameters (groans) code for quality.
