The Importance Of Lithologic Variability And Stratigraphic Architecture In The Development Of Eogenetic Karst Systems, Nicholas J. Soto-Kerans
The Importance Of Lithologic Variability And Stratigraphic Architecture In The Development Of Eogenetic Karst Systems, Nicholas J. Soto-Kerans
USF Tampa Graduate Theses and Dissertations
Integrative characterizations of karst systems on low-lying eogenetic carbonate platforms are rare and often limited to areas of direct observation where caves can be entered and explored. Because hydraulic properties of eogenetic limestones have been implicitly assumed to be homogeneous, classical models of carbonate island karst development stressed the importance of geochemical interfaces in controlling cave and vug development. These studies have explained the largest cavern systems as results of either 1) mixing dissolution at platform margins or 2) microbially-mediated dissolution processes at water tables.

Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, Ivan Marin, Ilya Turbanov
Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, Ivan Marin, Ilya Turbanov
International Journal of Speleology
Based on the morpho-genetic study of stygobiotic shrimps from the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae), a hydrogeological connection of a number of distant caves in Central Abkhazia of the southwestern Caucasus is satisfied, which indicates the possibility of using biospeleological studies in some cases to identify karst hydrosystems together with traditional hydrogeological methods. Moreover, a new stygobiotic atyid shrimp from the genus Xiphocaridinella, X. kelasuri sp. n., is described based on morphology and analysis of mitochondrial cytochrome oxidase I DNA sequences from three distant caves. The new species is genetically divergent from relatives and phylogenetically related to …
