Theses, Dissertations and Capstones

Studies were conducted on the natural history, ecology and potential stress of Ambystoma maculatum and Rana sylvatica at Dolly Sods, West Virginia. Temperature was found to be the primary stimulus influencing spring breeding migration of both species. Breeding period of R. sylvatica was found to be short in duration, resulting in deposition of eggs in large communal masses. Migration and breeding period of A. maculatum occurred from early-April to early-May. Egg deposition occurred from mid-April to mid-May. A second egg deposition of A. maculatum occurred mid-June. Temperature was found to have a significant influence on the rate of development in …


The Distribution, Ecology And Natural History Of Shrews (Insectivora: Soricidae) In Southern West Virginia, Jeffrey Jerome Hajenga Jan 1995

Theses, Dissertations and Capstones

A survey of the soricid (shrew) fauna of southern West Virginia was conducted between May 16, 1994 and May 27, 1995. Twenty-five sites were established in Mercer and Summers counties within seven habitat types. Pitfall traps were used and through a limitation of fluid depth within the trap the selectivity for soricids was increased to over 83% of the total capture. Overall, a total of 653 shrews comprising seven species (Sorex cinereus, S. /ongirostris, S. fumeus, S. dispar, S. hoyi, 8/arina brevicauda, and Cryptotis parva) was captured. Two of the species taken (S. hoyi and S. dispar) are new county …

Comparative Ecological, Morphological, And Behavioral Studies Of The Southern Blacknose Dace, Rhinichthys Atratulus Obtustjs Agassiz, And The Eastern Blacknose Dace, Bhinichtbis Atbatulus Atra'fulus (Hermann), In High And Low Altitude Streams In West Virginia And Virginia, Michael L. Little

Theses, Dissertations and Capstones

Comparative ecological, aorphological, and behavioral studies of the southern blaeknose dace, Rhiniohthys atratulus obtusus Agassiz, and the eastern blaokaose dace, B.hiniohtpys atratulus atratulus (Heraann), were made in high and low altitude streaas in West Virginia and Virginia. Statistical comparisons of the morphology of a. a.atratulus and R-.a.-obtusus showed no reliable body character that differentiated the two subspecies. Statistical tests indicated an intergrading population in Gandy Creek, a tributary of the Cheat River, in West Virginia. This was further substantiated by collecting males of the atratulus phenotype along with males of the native obtusus phenotype in adjacent sections of Gandy Creek. …
