Zoogeography and Biodiversity of Missouri Caves and Karst
The Missouri Cave Life Database contains 927 species and about 12,500 observation and collection records. About 1,038 (17%) of Missouri’s 6,200 caves and cave springs are biocaves with at least one species record, but only 491 sites (8%) have five or more species recorded. Missouri has 82 troglobites (67 described, 15 undescribed), including 49 aquatic and 33 terrestrial species. The aquatics i...
متن کاملBIOCHEMICAL MECHANISMS OF RESISTANCE TO p-NITROCHLOROBENZENE OF KARST CAVES MICROORGANISMS.
The biochemical mechanisms of resistance to persistent organic xenobiotic p-nitrochlorobenzene (NCB) of bacterial strains isolated from two cave clays ecosystems-Mushkarova Yama (Podolia, Ukraine) and Kuybyshevskaya (Western Caucasus, Abkhazia) have been established It has been determined that chemoorganotrophic karst caves strains could interact with NCB and transform it reducing the nitro gro...
متن کاملThe Study of Recent Destructive Processes in the Moravian Karst Caves (czech Republic)
This work tried to decide whether an occasionally observed falling of straw stalactites in the Moravian Karst caves is caused by a hypothetical chemical corrosion. The straw stalactite wall was found to be formed by three calcite layers. The middle layer (a stalactite skeleton) was typically cracked in agreement with calcite cleavage. Some impact of chemical corrosion was positively identified ...
متن کاملCulturable mycobiota from Karst caves in China, with descriptions of 20 new species
Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014-2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 11...
متن کاملStudy of the Critical Collapse Cave Span for Fracture-cavity Oil Storage Karst Caves
As the major field in petroleum reserve growth, fractured-vuggy reservoir is the key research in the future. However, in the development of fracture-cavity reservoir, collapse may occur in karst cave which greatly affects the oil well output. In order to forecast the cave collapse before drilling, this work adopts the method of span dichotomy reduction to determine the critical karst collapse o...
