説明
The process of coat color change of the snow-shoe hare, Lepus brachyurus angustidens HOLLISTER which inhabits in the north-eastern part of the mainland of Japan was studied from September of 1963 to April of 1966. It was found that illumination length per day has much to do with the color change. The results of experiments were as the following. The color change from brown to white from autumn to winter was inhibited by the exposure of animals to artificial illumination of longer than 12 hours per day with fluorescent lamps which started from the middle of September. The color change from white to brown from winter to spring was almost stopped by exposure to the artificial illumination of 10 hours per day in a dark room which started at the middle of February. Longer exposure accelerated the change of browning in white winter animals. Colored lights and temperatures exerted no influence to the color changes. From these results, the day-length in nature is considered to be most important among the environmental factors controlling the coat color change of the snow-shoe hare.
