Genetic evidence of a northward range expansion in the eastern Bering Sea stock of Pacific cod
Abstract Poleward species range shifts have been predicted to result from climate change, and many observations have confirmed such movement. Poleward shifts may represent a homogeneous shift in distribution, seasonal northward movement of specific populations, or colonization processes at the polew...
