Animal Ecology (1927)

English biologist and animal ecologist Charles Sutherland Elton published Animal Ecology in London at the press of Sidgwick & Jackson. It appeared as part of a series of textbooks in animal biology edited by Julian Huxley, who contributed a very informative introduction. In this book Elton integrated the concepts of food chains, pyramids of numbers, and the "niche" into a useful framework for ecology.
