The second edition of The Biology of Caves and Other Subterranean Habitats, part of the Biology of Habitats Series, offers a concise yet comprehensive introduction to the unique world of cave and subterranean biology. Authored by David C. Culver, this edition continues to explore the fascinating habitat and its biodiversity through a range of biological processes such as ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation. Utilizing examples from both caves and non-cave subterranean habitats globally, the authors provide clarity on specialized terms used by researchers while minimizing their usage. The book retains its 10-chapter structure but has been thoroughly revised and updated to reflect the significant increase in publications on subterranean biology over the past decade.
