Arsenic Affects Muscle Development And Structure In Fundulus Heteroclitus, Angela D'Amico
All Theses
Arsenic is a naturally occurring metalloid that can enter rivers and ground water. Epidemiological studies have correlated arsenic exposure with adverse developmental outcomes such as low birth weight, delays in the use of musculature, and altered locomotor activity. Previously in our lab, embryonically exposed killifish (Fundulus heteroclitus) were found to have changes in muscle development. Microarray analysis showed several genes involved in muscle development and formation altered and histological analysis showed an increase in small muscle fiber size. In this study, killifish were used to help understand if changes in muscle formation and fiber density after embryonic exposure persist, are …

Landscape Scale Correlates Of Fox Squirrel (Sciurus Niger) Presence , Kristin Meehan
All Theses
Although declining throughout the southeast, fox squirrel (Sciurus niger) populations are found on some golf courses in rapidly developing coastal South Carolina. This study used 2001 National Landcover Database data to investigate the relationship between fox squirrel presence on golf courses and landscape-scale habitat features. Results indicated that the best predictor of fox squirrel presence on a course was the presence of a fox squirrel population on the nearest neighbor course, regardless of distance. Course age and the total area of undeveloped features on the course were the best predictors of fox squirrel presence on golf courses without …
