Biological Sciences Theses & Dissertations
A study was conducted on the food habits of the black bear (Ursus americanus) in the Great Dismal Swamp of Virginia. A total of four stomachs and 42 scats were analyzed. Four samples were collected from September and October of 1975, and the remainder of the samples were collected from September 1976 to February 1977. The study was conducted to obtain information vital to the management of this species in the Great Dismal Swamp. Vitis spp. was the primary food item during the fall comprising 43% of the total diet, followed by fruits of Diospyros virginiana and Asimina triloba, each …
Herbaceous Production In Burned-Cut Burned-Uncut And Control Areas Of A Chamaecyparis Thyoides (L.) Bsp (Cupressaceae) Stand In The Great Dismal Swamp, Caroline Elisabeth Mckinley
Herbaceous Production In Burned-Cut Burned-Uncut And Control Areas Of A Chamaecyparis Thyoides (L.) Bsp (Cupressaceae) Stand In The Great Dismal Swamp, Caroline Elisabeth Mckinley
Biological Sciences Theses & Dissertations
The herbaceous layer of an Atlantic white cedar (Chamaecyparis thyoides) stand in the Great Dismal Swamp was sampled to estimate the productivity of two burned areas and a control area. The herbaceous vegetation was sampled along three transects utilizing the harvest method and productivity values were estimated using peak biomass values for each individual species. The burned-cut area had the highest productivity (3623 kg ha-l yr-1) and was characterized by species of the Asteraceae, Poaceae, and Cyperaceae. The burned-uncut area had a productivity value of 1636 kg ha-1 yr-1 with similar species of the Asteraceae …
