Distribution And Conservation Genetics Of The Cow Knob Salamander, Plethodon Punctatus Highton (Caudata: Plethodontidae), Matthew R. Graham
Distribution And Conservation Genetics Of The Cow Knob Salamander, Plethodon Punctatus Highton (Caudata: Plethodontidae), Matthew R. Graham
Theses, Dissertations and Capstones
Being lungless, plethodontid salamanders respire through their skin and are especially sensitive to environmental disturbances. Habitat fragmentation, low abundance, extreme habitat requirements, and a narrow distribution of less than 70 miles in length, makes one such salamander, Plethodon punctatus, a species of concern (S1) in West Virginia. To better understand this sensitive species, day and night survey hikes were conducted through ideal habitat and coordinate data as well as tail tips (10 to 20 mm in length) were collected. DNA was extracted from the tail tips and polymerase chain reaction (PCR) was used to amplify mitochondrial 16S rRNA gene fragments. …
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Theses, Dissertations and Capstones
Since 1971, documented Rough Greensnake (Opheodrys aestivus) occurrences in West Virginia have declined from approximately 100 to less than 20 occurrences in the last 10 years. In contrast to the decline of Rough Greensnakes in WV, Smooth Greensnake (O. vernalis) populations appear to be stable over the same period of time. Historic sites from the West Virginia Biological Survey were cross referenced with habitat descriptions in published literature to establish research locations. One hundred nineteen Rough and Smooth Greensnakes were measured for snout-vent length and total body length, and of these, 78 were measured in detail for external head morphology …
Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer
Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer
Theses, Dissertations and Capstones
The Eastern Hellbender, Cryptobranchus alleganiensis alleganiensis, is a species of concern in West Virginia and is in need of management. An important component of conservation efforts will involve identifying suitable habitat for protection. The goal of this research was to locate populations and examine hellbender habitat preferences to help managers identify habitat for protection. Populations were located using rock turning surveys from May through November, 2006. Hellbenders may be sensitive to water chemistry, so the dissolved oxygen, pH, turbidity, specific conductivity, and water temperature were measured. Substrate composition may influence populations, so substrate was characterized with Wolman pebble counts. …
Status, Distribution, And Density Of White-Tailed Jackrabbits And Black-Tailed Jackrabbits In South Dakota, Dustin J. Schaible
Status, Distribution, And Density Of White-Tailed Jackrabbits And Black-Tailed Jackrabbits In South Dakota, Dustin J. Schaible
Electronic Theses and Dissertations
The status of jackrabbit (Lepus spp.) populations throughout the Northern Great Plains has been a cause for concern by wildlife managers in recent years and there has been a paucity of information about the ecology of the white-tailed jackrabbit (Lepus townsendii) and the black-tailed jackrabbit (Lepus californicus) in South Dakota. Since there have been little monitoring efforts for hares, 21 permanent spotlight line transects were established across South Dakota for future surveying efforts. These transects were surveyed to obtain baseline information about jackrabbit density and distribution throughout the state. Jackrabbit density was highest in the northwestern portions of the state …
