Concordance between genetic diversity and marine biogeography in a highly mobile marine mammal, the Risso's dolphin
Abstract Aim The heterogeneity of the marine environment is thought to be the origin of marine biodiversity, often delineated in marine biogeographical provinces. Cetaceans are highly mobile aquatic mammals, but even those species inhabiting seemingly boundary‐free open waters are found to exhibit d...
