Washington: Smithsonian Institute Press, 1991. Cloth & boards. xviii, 222 pp + plates, indexed. Fine in fine jacket. " [Shelford's] early work on the sand dunes, ponds, streams, and forests bordering Lake Michigan led to the acceptance of animal ecology as a distinct discipline within the biological sciences. Shelford developed the concept of ecological succession of animals, and he was among the first to consider food webs, the intricate interrelationships in feeding habits that ultimately determine species composition and community structure. During World War I Shelford examined the effects of industrial pollution on fish, natural resources, and public health; his work marked the beginnings of water polluction biology." - jacket; Octavo 087474315X
