About 50 years ago, D.W.Kaufman investigated the effects of a mouse’s coat color in a specific environment on the rate of nighttime predation by hungry owls. He also investigated the effects of the amount of moonlight on this predation as well. . LIFESTAGES . OF OYSTERS . Crassostrea virginica. : . implicationS for freshwater . management . Aswani K.
