It is found that the vocal repertoire of Corsican Deer was very comparable with that of central European and Scottish Red Deer, with the exception of one call type, the harsh roar, absent in the Corsican deer repertoire.
The evolution of acoustic size exaggeration in terrestrial mammals

It is shown that male terrestrial mammals produce vocal signals with lower ΔF (but not F0) than expected for their size in mating systems with greater sexual size dimorphism and supports the notion of an evolutionary trade-off between pre-copulatory signalling displays and sperm production.

Cues to body size in the formant spacing of male koala (Phascolarctos cinereus) bellows: honesty in an exaggerated trait
- B. Charlton, W. Ellis, W. Fitch
- PhysicsJournal of Experimental Biology
- 15 October 2011
The findings show that the formant spacing of male koala bellows has the potential to provide receivers with reliable information on the caller's body size, and reveal that vocal adaptations allowing callers to exaggerate (or maximise) the acoustic impression of their size have evolved independently in marsupials and placental mammals.
Menstrual cycle phase alters women's sexual preferences for composers of more complex music

Results suggest that women may acquire genetic benefits for offspring by selecting musicians able to create more complex music as sexual partners, and provide compelling support for Darwin's assertion ‘that musical notes and rhythm were first acquired by the male or female progenitors of mankind for the sake of charming the opposite sex’.

Vocal cues indicate level of arousal in infant African elephant roars.

Findings indicate that infant African elephant roars primarily function to signal the caller's arousal state, which may allow mothers to respond differentially based on their infant's degree of need and may be crucial for the survival of infant African elephants in their natural environment.
Female red deer prefer the roars of larger males

It is suggested that sexual selection through female mating preferences may have provided an additional selection pressure along with male–male competition for broadcasting size-related information in red deer and other mammals.
Vocal cues to identity and relatedness in giant pandas (Ailuropoda melanoleuca).

It is revealed that giant panda bleats are highly individualized and indicate that source-related features, in particular, mean fundamental frequency, amplitude variation per second, and the mean extent of each amplitude modulation, contribute the most to vocal identity.
Perception of Male Caller Identity in Koalas (Phascolarctos cinereus): Acoustic Analysis and Playback Experiments

The findings indicate that male koala bellows are highly individually distinctive and that the identity of male callers is functionally relevant to male and female koalas during the breeding season.
