Male-female interaction is important for finding a suitable mating partner and for ensuring
reproductive success. Male sexual signals such as pheromones transmit information and …

Despite their reputation for being elusive, deer are in fact highly vocal animals. Conspicuous
calls have been systematically found in both sexes of all studied species, and one genus …

Sexual size dimorphism may evolve as a result of both natural and sexual selection. In
polygynous mammals, the main factor resulting in the evolution of large body size in males …

Surprisingly little is known about the role of acoustic cues in mammal female mate choice.
Here, we examine the response of female red deer (Cervus elaphus) to male roars in which …

Human aggression is viewed from four explanatory perspectives, derived from the
ethological tradition. The first consists of its adaptive value, which can be seen throughout …

Background Models of honest advertisement predict that sexually selected calls should

In ungulates, males and females have contrasting life histories, as usually only the females
raise the young. How reproductive effort in males varies with individual level and population …

study, we use capture–mark–resighting and multi–state models to examine survival …

Mammals are able to distinguish conspecifics based on vocal cues, and the acoustic
structure of mammal vocalizations is directly affected by the anatomy and action of the vocal …

A range of acoustic characteristics typically carry information on individual identity in
mammalian calls. In addition, physical similarities in vocal production anatomy among …
