Biogeography and temporal progression during the evolution of striped dolphin population structure in European waters
Abstract Aim We investigated the population genetic structure of a highly mobile marine species, the striped dolphin, Stenella coeruleoalba (Meyen, 1833), along a geographical range with habitat transitions and historical dynamics to identify the causes of genetic divergence, and to assess the effec...
