VOCAL BEHAVIOUR IN THE ENDANGERED CORSICAN DEER: DESCRIPTION AND PHYLOGENETIC IMPLICATIONS
ABSTRACT Here we present the first description of the vocal behaviour of the Tyrrhenian subspecies of Red Deer, the Corsican Deer. Vocalisations from calves, hinds and stags were recorded. TheirExpand

The information content of giant panda, Ailuropoda melanoleuca, bleats: acoustic cues to sex, age and size
The acoustic structure of mammal vocalizations often encodes information on different phenotypic traits of the caller that is potentially available to receivers. Here we used a source–filter theoryExpand

Female red deer prefer the roars of larger 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 an acoustic cue toExpand

The cry embedded within the purr
Summary Despite widespread interest in inter-specific communication, few studies have examined the abilities of companion animals to communicate with humans in what has become their naturalExpand

Vocal cues indicate level of arousal in infant African elephant roars.
Arousal-based physiological changes influence acoustic features of vocalizations in mammals. In particular, nonlinear phenomena are thought to convey information about the caller's arousal state.Expand

Perception of Male Caller Identity in Koalas (Phascolarctos cinereus): Acoustic Analysis and Playback Experiments
The ability to signal individual identity using vocal signals and distinguish between conspecifics based on vocal cues is important in several mammal species. Furthermore, it can be important forExpand

Cues to body size in the formant spacing of male koala (Phascolarctos cinereus) bellows: honesty in an exaggerated trait
SUMMARY Determining the information content of vocal signals and understanding morphological modifications of vocal anatomy are key steps towards revealing the selection pressures acting on a givenExpand

The evolution of acoustic size exaggeration in terrestrial mammals
Recent studies have revealed that some mammals possess adaptations that enable them to produce vocal signals with much lower fundamental frequency (F0) and formant frequency spacing (ΔF) thanExpand

Oestrous red deer hinds prefer male roars with higher fundamental frequencies
Across vertebrates, the observation that lower-pitched vocalizations are typically associated with larger and/or higher quality males has lead to the widespread belief that inter- and intra-sexualExpand

Vocal cues to identity and relatedness in giant pandas (Ailuropoda melanoleuca).
A range of acoustic characteristics typically carry information on individual identity in mammalian calls. In addition, physical similarities in vocal production anatomy among closely relatedExpand
