A System for Monitoring Acoustics to Supplement an Animal Welfare Plan for Bottlenose Dolphins

Animal sounds are commonly used by humans to infer information about their motivations and their health, yet, acoustic data is an underutilized welfare biomarker especially for aquatic animals. Here, we describe an acoustic monitoring system that is being implemented at the U.S. Navy Marine Mammal Program where dolphins live in groups in ocean enclosures in […]

Vocalisation of domestic pigs () as an indicator for their adaptation towards ambient temperatures

It was tested whether the vocalisation of pigs can be used to assess their adaptability to ambient temperatures. It was hypothesised that the proportion of high-frequency vocalisation, indicating discomfort, would increase with behavioural reactions to both low and high ambient temperatures and that this relationship is modified by the weight of pigs. In addition, the […]

Vocal activity of lesser galagos (Galago spp.) at zoos

Almost nothing is known about the natural vocal behavior of lesser galagos living in zoos. This is perhaps because they are usually kept in nocturnal exhibits separated from the visitors by a transparent and acoustically insulating glass barrier. The aim of the present study was therefore to fill this gap in knowledge of the vocal […]
