Geographic variation of whistles of the striped dolphin (Stenella coeruleoalba) within the Mediterranean Sea
The striped dolphin is a cosmopolitan species distributed worldwide. Morphological and genetic studies strongly suggest that the Mediterranean and eastern North Atlantic populations are isolated from each other. The Mediterranean population is considered a distinct conservation unit by International...
