Habitat Utilization And Impact Of Flooding On James Spinymussel (Parvaspina Collina) Populations In Virginia Streams, Christine A. Verdream
Habitat Utilization And Impact Of Flooding On James Spinymussel (Parvaspina Collina) Populations In Virginia Streams, Christine A. Verdream
Masters Theses, 2020-current
The James spinymussel (Parvaspina collina) is Critically Endangered and endemic to Virginia’s James River basin. P. collina was listed as Endangered in 1988 and more than 90% of the species has been lost over the last 30 years (USFWS 1990). Despite the development of a recovery plan in 1990, there has not been a comprehensive reassessment of P. collina in over 30 years. This study explored the relationship between flooding and P. collina population dynamics in a flood prone stream and further explained habitat occupancy. Study sites included Swift Run and Little Oregon Creek, both of which still …

Modeling Species Distribution And Habitat Suitability Of American Ginseng (Panax Quinquefolius) In Virginia, Jacob D. J. Peters
Masters Theses, 2020-current
American ginseng (Panax quinquefolius) is a well-known and sought-after medicinal plant native to North America that is facing increased threat of extinction due to overharvesting, herbivory, and habitat loss. Species distribution and habitat suitability models may be valuable to landowners interested in sustainable harvest or to institutions interested in the conservation and restoration of the species. With unequal sampling efforts across a region of interest, it is likely that some locations with appropriate habitat may be misrepresented in model predictions. This study refined a state-derived species distribution model for ginseng through increased sampling effort across the Cumberland Plateau …
