Subterranean ecosystems

de David C. Culver, William F. Humphreys

"This book shows the importance for the biosphere of a previously neglected biota. The types of animals and habitats found in subterranean ecosystems are described together with the geological formations in which they occur and their distribution on earth. The ecology of some subterranean terrestrial and aquatic systems are described together with subterranean ecosystems in different climatic zones. The nature of the adaptations to life in complete darkness, and to the often sparse and patchily distributed foods or various trophic origins, are described. A central part of the volume deals with the characteristics and process involved in the adaptation, speciation and evolution of subterranean animals. The volume concludes with a consideration of the conservation issues arising." "For ecologists, biologists, speleologists, conservation planners and land managers."--Jacket.
