Quantifying the signals produced by a species is a fundamental step in the investigation of their functionality, geographical differences and social and cultural transmission.
BOTTLENOSE DOLPHIN ACOUSTIC
The project aims to increase the knowledge on the communication system of the bottlenose dolphin in the Mediterranean Sea, focusing on whistles. In particular, the first objective is to identify and characterize the signature whistles of different Mediterranean bottlenose dolphin "populations". Further, we investigate the effects of behavioral, anthropic and social variables on the acoustic structure of dolphin whistles. At the end, by collecting sounds of dolphins in different parts of the Mediterranean Sea, we study the factors (geographic position and isolation, behavioural and social context, noise levels, presence of boats) that can lead acoustic divergence between populations.
