 wrote Animal Communities in Temperate America in 1913, where he outlines three main principles of ecology, (a) emphasizing the importance of studying the physiology of the organism, rather than the physiology of a specific organ; (b) evaluating the “phenomena of behavior and physiology” in relation to the natural environments; and (c) relating the ecology of plant life to that of animal life. From Gordon Hewitt's 1921 book The Conservation of the Wildlife of Canada, Elton noticed the Canadian Lynx and Snowshoe Hare
Snowshoe Hare
The Snowshoe Hare , also called the Varying Hare, or Snowshoe Rabbit, is a species of hare found in North America. It has the name "snowshoe" because of the large size of its hind feet and the marks its tail leaves. The animal's feet prevent it from sinking into the snow when it hops and walks...
