摘要：
Melanism in gray squirrel is found primarily in urban populations and near the northern limit of the species' range. Selected behaviors were examined in Syracuse, New York. Results suggest that the distribution of color morphs is not due to pleiotropic behavioral trait differences, that neither morph is likely to have a mating advantage, and the variation among demes suggests random factors (drift). -from Authors
