Cave ecologies are very diverse, and not sharply distinct from surface habitats. Generally however, the deeper the cave becomes, the more rarefied the ecology. Cave environments fall into three general categories: * Endogean: the parts of caves that are in communication with surface soils through cracks and rock seams, groundwater seepage, and root protrusion. * Parahypogean: the threshold regions near cave mouths that extend to the last penetration of sunlight. * Hypogean: or "true" cave environments. These can be in regular contact with the surface via wind and underground rivers, or the migration of animals, or can be almost entirely isolated. Deep hypogean environments can host autonomous ecologies whose primary source of energy is not sunlight, but chemical energy liberated from limestone and other minerals by chemoautotrophic bacteria. Cave organisms fall into three basic classes: * Troglobites ("cave dwellers") are obligatory cavernicoles, specialized for cave life. Some can leave caves for short periods, and may complete parts of their life cycles above ground, but cannot live their entire lives outside of a cave environment. Examples include chemotrophic bacteria, some species of flatworms, collembola, and Blindfish.

Extractions: The Cave Biology Research Group (CBRG) at New York University contains evolutionists, developmental biologists, conservationists and educators. Current projects include comparative genomic mapping to find the genes responsible for eye regression and depigmentation in different populations of cave fishes, phylogenetic studies, and educational projects. For information about the CBRG, e-mail to rb4@scires.nyu.edu Details of the research rationale for the laboratory of Richard Borowsky (Department of Biology, NYC, NY 10003) are as follows: Research Interests and Rationale: The Evolution of Troglomorphy Regressive Evolution The Genetics of Complex Traits The Importance of Replication in Evolutionary Studies My laboratory currently concentrates on the study of cave fishes, viewing them as powerful models for the investigation of interesting problems in evolutionary biology, including speciation, the genetics of trait evolution, and regressive evolution. About eighty species of cave fishes are presently known world-wide, and the rate of discovery of new ones is accelerating. While these species fall into a number of very distinct and different fish families, they share a set of characteristics typical of all cave animals. The most obvious of these traits are reduced eyes and pigment, but they also tend to share other heightened extraoptic senses ( e.g
