Whistles as potential indicators of stress in bottlenose dolphins (Tursiops truncatus)
We examined the possibility that parameters of bottlenose dolphin signature whistles may serve as indicators of stress. Bottlenose dolphins (Tursiops truncatus) in Sarasota Bay, Florida, were recorded during brief capture–release events, which are potentially a source of short-term stress to these dolphins, although no effects of chronic or long-term stress have been observed over the […]
Modulation of whistle production related to training sessions in bottlenose dolphins (Tursiops truncatus) under human care
Bottlenose dolphins are highly social cetaceans with an extensive sound production including clicks, burst-pulsed sounds, and whistles. Some whistles, known as signature whistles, are individually specific. These acoustic signatures are commonly described as being emitted in contexts of stress during forced isolation and as group cohesion calls. Interactions between humans and captive dolphins is largely […]
