Examining Habitat Selection And Home Range Behavior At Multiple Scales In A Population Of Eastern Box Turtles, (Terrapene C. Carolina), With Notes On Demographic Changes After 17 Years, Brian Anthony Williamson
Theses, Dissertations and Capstones
The Eastern Box Turtle, Terrapene c. carolina, is a terrestrial species native to the eastern United States. Once considered common, it is currently declining in much of its range due to habitat destruction and disease. To conserve the species, knowledge of Eastern Box Turtle habitat selection and the factors influencing their movement is necessary. Although the home range behavior of the Eastern Box Turtle has been well studied, few studies have quantified habitat selection at the home-range scale. Therefore, I examined home-range selection and within home range habitat selection in a population of Eastern Box Turtles at Hungry Beech Nature …
The Natural History And Distribution Of The Mountain Earthsnake (Virginia Valeriae Pulchra) In West Virginia, Daniel Ware
The Natural History And Distribution Of The Mountain Earthsnake (Virginia Valeriae Pulchra) In West Virginia, Daniel Ware
Theses, Dissertations and Capstones
The Mountain Earthsnake, Virginia valeriae pulchra, has received little attention in the literature to date. It is imperiled in West Virginia with only 6 to 20 populations known throughout the Allegheny Mountain and Ridge and Valley Physiographic provinces. Eighty snakes were collected during the 2006 and 2007 summers. Typical habitat is open fields with short grass, flat to moderate slopes that have scattered fine sandstone rocks near a source of water and forest edge. Fine sandstone rocks were the primary cover objects used. Snakes were sexually dimorphic with males having longer tails expressed as a percent of total body lengths …
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 …
