In adaptating to perpetual darkness, cave species gradually lose eyes and body pigmentation and evolve alternatives for exploring their environments. Although troglodyte features evolved independently many times in cavefish, we do not yet know whether independent evolution of these characters involves common genetic mechanisms. Surface-dwelling and many cave-dwelling species make the freshwater...

Kapova Cave (Shulgan-Tash) is located in Bashkortostan, the Southern Urals, in the Shulgan Tash Reserve on the Belaya River. Its coordinates are 53°02’ N; 57°03’ W. It is a large karst three-level system of chambers, galleries and wells having the total length of 3323 m with vertical amplitude of 165 m. The karst system is characterized by large chambers and galleries, great dynamics of microcl...

The evolution of surface subsidence is an important focus of study above Molycorp, Inc.’s newest block cave at the Questa molybdenum mine near Taos, New Mexico. The case study compares mature glory hole subsidence over the Goathill Orebody and subsidence emerging in its earliest stage over the new D Orebody block cave. Subsidence above the D Orebody was first detected in April 2003, 30 months a...

Vrelo Cave is the deepest cave in Macedonia, located in the canyon Matka which is home to many endemic species not found anywhere else in Europe. Until now, Vrelo Cave has not been investigated in terms of its composition and biodiversity. The purpose of this study was to offer some preliminary data for physical and chemical parameters of water and sediments from Vrelo Cave, as well as its micr...

Previous metaphor studies have paid much attention to nominal and predicative metaphors and little attention has been given to adjective metaphors. Although some studies have focused on adjective metaphors, they have only examined how the acceptability of adjective metaphors can be explained by the pairing of adjective modifier’s and head noun’s modalities and little attention has been given to...

The evolutionary forces driving the reduction of eyes and pigmentation in cave-adapted animals are unknown; Darwin famously questioned the role of natural selection in eye loss in cave fishes: "As it is difficult to imagine that eyes, although useless, could be in any way injurious to animals living in darkness, I attribute their loss wholly to disuse"[1]. We studied the genetics of eye and pig...

Obligatory cave species exhibit dramatic trait modifications such as eye reduction, loss of pigmentation and an increase in touch receptors. As molecular studies of cave adaptation have largely concentrated on vertebrate models, it is not yet possible to probe for genetic universalities underlying cave adaptation. We have therefore begun to study the strongly cave-adapted small carrion beetle P...
