Small Mammal Communities In Riparian And Upland Habitats On The Upper Coastal Plain Of Virginia, A. Scott Bellows, Joseph C. Mitchell
Small Mammal Communities In Riparian And Upland Habitats On The Upper Coastal Plain Of Virginia, A. Scott Bellows, Joseph C. Mitchell
Virginia Journal of Science
We compared small mammal communities between riparian (stream corridor) and nearby upland habitats in a hardwood forest ecosystem on Fort A.P. Hill, Caroline County, Virginia. We used a combination of small-scale drift fence/pitfall trap arrays and snap traps to capture small mammals during April – October 1998, with an additional winter sample in January 1999. We captured seven small mammal species at 14 sites (7 pairs). Numbers of species were not significantly different between habitat types. Bray-Curtis polar ordinations showed that plant and small mammal community compositions were similar in upland sites and that these communities were most varied in …
Observations On Amphibians And Reptiles In Burned And Unburned Forests On The Upper Coastal Plain Of Virginia, Joseph C. Mitchell
Observations On Amphibians And Reptiles In Burned And Unburned Forests On The Upper Coastal Plain Of Virginia, Joseph C. Mitchell
Virginia Journal of Science
I evaluate the results of a short-term study on the effects of prescribed burning on terrestrial amphibians and reptiles on Fort A.P. Hill, Caroline County, Virginia. Six species of amphibians and reptiles were observed in unburned sites and eight species were observed in burned sites. More individual amphibians (46) were observed in unburned stands than in burned stands (15). Adults of two species (Bufo americanus, Plethodon cinereus) were found dead under logs in the still smoldering prescribed burn. The results of this study suggest that prescribed burning may have some negative effects on amphibians and reptiles. Because …
Feeding Habits Of Young-Of-Year Striped Bass, Morone Saxatilis, And White Perch, Morone Americana, In Lower James River, Va, Paul J. Rudershausen, Joseph G. Loesch
Feeding Habits Of Young-Of-Year Striped Bass, Morone Saxatilis, And White Perch, Morone Americana, In Lower James River, Va, Paul J. Rudershausen, Joseph G. Loesch
Virginia Journal of Science
A total of 188 young-of-year (YOY) striped bass, Morone saxatilis, and 199 YOY white perch, Morone americana, were collected by pushnet, seine and trawl during 24-hour periods from June through August, 1992 in lower James River, Virginia. The purpose was to identify prey and temporal and spatial feeding habits. Copepods were the most numerous prey of both species. Fishes and mysids comprised the largest volumetric percentage of diets of striped bass and white perch, respectively. Using an index of relative importance, leptodorids and copepods were the most important prey of striped bass and white perch, respectively. Both species …
Conservation Status Of The Southern Appalachian Herpetofauna, Joseph C. Mitchell, Thomas K. Pauley, David I. Withers, Steven M. Roble, Brian T. Miller, Alvin L. Braswell, Paul V. Cupp Jr., Christopher S. Hobson
Conservation Status Of The Southern Appalachian Herpetofauna, Joseph C. Mitchell, Thomas K. Pauley, David I. Withers, Steven M. Roble, Brian T. Miller, Alvin L. Braswell, Paul V. Cupp Jr., Christopher S. Hobson
Virginia Journal of Science
Seventy one species of amphibians (55 salamanders, 16 anurans) and 46 species of reptiles (15 turtles, 8 lizards, 23 snakes) inhabit a five state area (Kentucky, North Carolina, Tennessee, Virginia, West Virginia) in the southern Appalachian region bordered by the Potomac River, the Blue Ridge Mountains, and the western margin of the Appalachian Plateau. Of these, 47.9 % of the amphibian fauna and 52.2 % of the reptilian fauna are listed as being of conservation concern by federal, state, and Natural Heritage programs in all or a portion of their ranges of this region. The Shenandoah salamander (Plethodon Shenandoah …
