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 کاملPost-speleogenetic Biogenic Modification of Gomantong Caves, Sabah, Borneo
The Gomantong cave system of eastern Sabah, Malaysia, is well-known as an important site for the harvesting of edible bird’s-nests and, more recently, as a tourist attraction. Although the biology of the Gomantong system has been repeatedly studied, very little work has been done of the geomorphology. Here we report on the impact of geobiological modification in the development of the modern as...
متن کاملComment on ‘‘coastal Caves in Bahamian Eolian Calcarenites: Differentiating between Sea Caves and Flank Margin Caves Using Quantitative Morphology’’
Waterstrat et al. (JCKS (2010), 72 (2) 61–74) compared means of geometric measurements of sea and flank margin caves with the Student t-test and concluded that these different types of caves could be ‘‘statistically differentiated.’’ However, their use of the t-test is dependent on the data being normally distributed. The data that were analyzed, cave area to perimeter ratio, entrance-width to ...
متن کاملAge Constraints for Clastic Sediments from Two Caves in the Junee-florentine Karst, Tasmania
Uranium-thorium dating of speleothems from two caves in the Junee-Florentine karst, Tasmania, provides some age constraints for associated clastic sediments including coarse dolerite-rich fluvial gravels, which underlie the three oldest dated speleothems. The results suggest minimum ages of 15 ± 5 ka, ~325 ka and >350 ka (two dates) for the gravels, implying that they are considerably older tha...
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 ...
