The fundamental frequency (F0) is a key parameter for characterising structures in vertebrate vocalisations, for instance defining vocal repertoires and their variations at different biological scales ( e.g population dialects, individual s...
Individual variation in two types of advertisement calls of Pacific tree frogs, Hyliola (=Pseudacris) regilla, and the implications for sexual selection and species recognition [0.03%]

Anuran advertisement calls play a fundamental role in social interactions related to reproduction, like territory defense and mate attraction. As such, advertisement calls are often shaped by natural and sexual selection. Therefore, to unde...

Croaking gouramis (genus Trichopsis, Anabantoidei) generate series of two-pulsed bursts (croaks) during agonistic interactions. Sex-specific differences are minor in T. vittata which raises the question whether sexes differ in the other two...

The human-elephant conflict is one of the most serious conservation problems in Asia and Africa today. The involuntary confrontation of humans and elephants claims the lives of many animals and humans every year. A promising approach to all...

Animal vocal signals are increasingly used to monitor wildlife populations and to obtain estimates of species occurrence and abundance. In the future, acoustic monitoring should function not only to detect animals, but also to extract detai...
Acoustic profiling in a complexly social species, the American crow: caws encode information on caller sex, identity, and behavioural context [0.03%]

Previous research on inter-individual variation in the calls of corvids has largely been restricted to single call types, such as alarm or contact calls, and has rarely considered the effects of age on call structure. This study explores st...
