Swimming in the deep end of the gene pool: global population structure of an oceanic giant
Abstract Despite the impression held by some that few biological mysteries remain, even evocative species such as humpback whales ( Megaptera novaeangliae ), white sharks ( Carcharodon carcharias ) and green turtles ( Chelonia mydas ) have poorly documented movement patterns, reproductive strategies...
