Genetic structure of cetacean populations in sympatry, parapatry, and mixed assemblages: implications for conservation policy
Many cetaceans have a wide distribution in one or more oceans, and in some species, individuals migrate over an extensive range. When breeding sites are geographically distant from foraging grounds, as for a number of baleen whales, genetic stocks may be geographically isolated during a breeding sea...

Many cetaceans have a wide distribution in one or more oceans, and in some species, individuals migrate over an extensive range.
