Using environmental DNA methods to survey for rare groundwater fauna: Detection of an endangered endemic cave crayfish in northern Alabama.

The conservation and management of subterranean biodiversity is hindered by a lack of knowledge on the true distributions for many species, e.g., the Wallacean shortfall.

A new species of stygobitic snail in the genus Hershler & Thompson, 1990 (Gastropoda, Cochliopidae) from the Appalachian Valley and Ridge of eastern Tennessee, USA.

A new species of cave snail (Littorinimorpha: Cochliopidae) in the genus is described from the dark zone of two caves in the Appalachian Valley and Ridge province in eastern Tennessee, United States. The Tennessee Cavesnail, Perez, Shoobs, Gladstone, & Niemiller, is distinguished from its only known congener, , by the absence of raised tubercles on its finely spirally striate protoconch, and its unique radular formula. Moreover, is genetically distinct from based on substantial divergence at the mitochondrial CO1 locus.
