Regulation of Parasite Populations is composed of the proceedings of a symposium held at New Orleans, on November 10-14, 1975, and jointly sponsored by the American Microscopial Society and the American Society of Parasitologists. The symposium focuses on the literatures dealing with the regulation of parasite populations. It also introduces some concepts and notions regarding this field of interest. This book reports the five papers presented in the symposium, beginning with the concept of parasitism. It specifically explains the regulation of fish parasite populations and the role of arrested development in the regulation of nematode populations. Aside from the subject at hand, the complementary nature of laboratory work, field studies, and mathematical modeling are explained. This compilation corresponds to an effort to "bridge a gap between some of the ideas and thoughts in ecology and parasitology.
