Systematics, conservation and morphology of the spider genus Tayshaneta (Araneae, Leptonetidae) in Central Texas Caves
The spider genus Tayshaneta is revised based on results from a three gene phylogenetic analysis (Ledford et al. 2011) and a comprehensive morphological survey using scanning electron (SEM) and compound light microscopy. The morphology and relationships within Tayshaneta are discussed and five species-groups are supported by phylogenetic analyses: the anopica group, the coeca group, the myopica ...
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 کاملEntranceless and Fractal Caves Revisited
Cave geometric properties have been studied between 1958 and today as statistical or fractal objects. These studies have divulged some degree of order in such properties as the distribution of cave lengths in a region and the distribution of cave passage sizes, and exhibiting some degree of self-similarity, suggesting a fractal nature, or moderate departures from self-similarity, suggesting geo...
متن کاملSession title: CAVES IN CONTEXT: THE ECONOMICAL, SOCIAL, AND RITUAL IMPORTANCE OF CAVES AND ROCKSHELTERS
Caves and rockshelters are found all over the world, and they have been frequently occupied throughout prehistory and early history. In many areas of Europe, some of these natural places are still used as sites of worship and as shelter against the elements. There is great variability in their use. Some appear to only have traces of short occupations, while others have thick cultural deposits, ...
