The Cave Fauna of California
By W.R. Elliott, J.R. Reddell, D.C. Rudolph, G.O. Graening, T.S. Briggs, D. Ubick, R.L. Aalbu, J. Krejca, S.J. Taylor
Proceedings of the California Academy of Sciences (Series 4) Volume 64, Supplement 1, 2017
Abstract:
Hidden biodiversity is revealed in this study of California's subterranean fauna, which contains distinctive elements that differentiate it from other North American regions. Since 1975, the rate of discovery of new species has accelerated with funded projects in most of the important cave areas of the state, including our own studies. Here we compile all available biological records for subterranean sites in California dating back to 1840.
California's karst is primarily comprised of small outcrops of marble or limestone with thousands of caves. Additionally, lava and ash flows, tens of thousands of mines, hundreds of sea caves on the mainland coast and islands, and extensive groundwater systems provide habitat for subterranean life.
