Hardbound. The last 50 years of research on the subterranean biome has revealed considerable taxonomic and ecological diversity as well as unique lineages of organisms - even a new animal class - dependent on a variety of energy sources. During this time biospeleology has developed from a descriptive discipline to encompass the whole field of biological science. The marked change of living conditions in the subterranean realm relative to the surface environment, due to the complete lack of light, provides unique opportunities to test various hypotheses. This book shows for the first time 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 clim
