Home Range And Behavior Of The Timber Rattlesnake (Crotalus Horridus), Jennifer P. Adams
Home Range And Behavior Of The Timber Rattlesnake (Crotalus Horridus), Jennifer P. Adams
Theses, Dissertations and Capstones
Seventeen timber rattlesnakes were surgically implanted with radio transmitters and subsequently radio-tracked to determine the home range and behavior, as well as cause-specific mortality, of timber rattlesnakes on production forests in Randolph County, West Virginia. Mean home range sizes were 94.3 ha, males; 31.2 ha, nongravid females; 8.5 ha, gravid females; and 44.7 ha, among sex classes. Among sex classes, the mean daily movement rate was 20.2 mper day; the mean maximum known distances from den sites was 1110.2 m; the mean distance from den sites was 514.2 m; and the mean total distance moved was 2852.9 m. Mean active …
Habitat Analysis By Hierarchical Scheme And Stream Geomorphology, James B. Spence
Habitat Analysis By Hierarchical Scheme And Stream Geomorphology, James B. Spence
Theses, Dissertations and Capstones
A study was undertaken to classify eight stream reaches in the North Branch of the Potomac River watershed and determine if geomorphologic differences influenced the availability of fish habitat structure and fish density. Stream reaches were classified using Rosgen Level II (1996) methods, and fish habitat was determined using Hydraulic Channel Unit (HCU) classification based on a method modified from Bisson et al. (1982). Other habitat variables were also studied such as stream shading and physical habitat based on the Rapid Bioassessment Protocol (Barbour et al. 1999). Despite the differences in HCU density between sites, HCU density did not influence …
Natural History And Conservation Biology Of A Southern West Virginia Contour Surface Mine Reptile And Amphibian Community, Zachary James Loughman
Natural History And Conservation Biology Of A Southern West Virginia Contour Surface Mine Reptile And Amphibian Community, Zachary James Loughman
Theses, Dissertations and Capstones
During the 2004-2005 field seasons, natural history of a herpetofaunal community was studied on an abandoned contour surface mine in Eccles, Raleigh County, West Virginia. This study is the first natural history investigation of amphibian and reptile populations present on an abandoned mine site. Specific natural history parameters for each order on the mine were investigated to determine what effect the post mining landscape had on herpetofaunal communities. Pond breeding caudates population success was dependent on life history parameters. Anurans were efficient at re-colonization, with 12 of a possible 14 species collected on the mine site. Anuran diversity was linked …
Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Theses, Dissertations and Capstones
Plethodon glutinosus populations in West Virginia were looked at in three different elevations. Objectives were to determine if there is enough difference in elevation to cause different populations to vary in morphology and reproduction. Nine morphological measurements were taken to represent both size and proportional shape. Sexual dimorphism was found in all measurements only in low elevations, males being larger (p<0.001-p=0.041). Mean measurements between the three elevations showed significant differences (p<0.005) in all measurements excluding head width, tail length, and 3rd digit length. Salamanders were dissected; testes and vasa deferentia were removed from males and ovaries with follicles were removed from females. Results showed males in lower and middle elevations deposit spermatophores May-July. Low sample sizes in higher elevations provided inconclusive results. Females of lower elevations lay eggs early-mid summer. Middle and higher elevations results revealed a likely spring oviposition, or possibly a fall oviposition.
The Natural History, Distribution, And Phenotypic Variation Of Cave-Dwelling Spring Salamanders, Gyrinophilus Spp. Cope (Plethodontidae), In West Virginia, Michael Steven Osbourn
The Natural History, Distribution, And Phenotypic Variation Of Cave-Dwelling Spring Salamanders, Gyrinophilus Spp. Cope (Plethodontidae), In West Virginia, Michael Steven Osbourn
Theses, Dissertations and Capstones
There are over 4000 documented caves in West Virginia, potentially providing refuge and habitat for a diversity of amphibians and reptiles. Spring Salamanders, Gyrinophilus porphyriticus, are among the most frequently encountered amphibians in caves. Surveys of 25 caves provided expanded distribution records and insight into ecology and diet of G. porphyriticus. Over 500 species locality records were compiled in a nearly comprehensive list. The Gyrinophilus population from General Davis Cave is of particular interest. In 1977, Besharse and Holsinger first described the West Virginia Spring Salamander, G. subterraneus; however, its taxonomic status is unclear. In order to …
