Fine-Scale Habitat Use Related To Crop Depredation By Female White-Tailed Deer In An Agricultural Landscape, Kent Allen Adams

Masters Theses

The white-tailed deer (Odocoileus virginianus) is the most popular game animal in the United States but is also responsible for a large amount of damage to agricultural crops. Understanding how deer use agricultural landscapes on a small scale will facilitate management. Global Positioning System (GPS) telemetry collars were attached to 16 female white-tailed deer at Chesapeake Farms, Kent County, Maryland, during 2 summer growing seasons (10 in 2001 and 6 in 2002). Twelve collars collected usable data and collar success averaged 90 and 86 percent in 2001 and 2002, respectively. Mean adaptive kernel home-range sizes (25.22 ha in …

The Effects Of Stocking Density, Amount Of Substrate, Frequency Of Feeding, And Waste Removal On Nursery Production And The Effects Of Substrate Height On Pond Production Of Freshwater Prawn Macrobrachium Rosenbergii, Alison Aria Ashby

Masters Theses

Production of freshwater prawn (Macrobrachium rosenbergii) in temperate regions has gradually increased over the past decade due to advances in research. However, production is limited to one seasonal crop in these regions, increasing the need to intensify production. A nursery phase has been implemented to produce larger juveniles to stock into production ponds.

Three nursery experiments (A, B, C) were performed to evaluate the effects of stocking density, amount of added substrate, feeding frequency, and waste removal on the survival and growth of juvenile prawn. Experiment A involved two concurrent studies. Prawn averaging 0.01 g were stocked at …

Inventory And Analysis Of Plankton In Green River Within Mammoth Cave National Park, Justin H. Laughlin

Masters Theses

National Park Service biological staff are charged with preserving and protecting all creatures within a park’s boundaries. It is only a matter of time before exotic zebra mussels (Dreissena polymorpha) invade all eastern waterways including Green River within Mammoth Cave National Park, Kentucky. The National Park Service, in cooperation with University of Tennessee, initiated this inventory of plankton within Mammoth Cave National Park to establish baseline data prior to zebra mussel invasion. During this two year study (2000-2002), 180 plankton samples were collected at three sampling sites which encompassed all major riverine habitat types within the three flow zones (free-flow, …

Soybean Hull Supplementation To Pasture-Based Beef Cattle Finishing Diets, Rebon Brent Pugh

Masters Theses

In the midsouthern United States, forages exist as the major nutrient source for grazing beef cattle. A large forage base allows this region to produce and market many feeder calves to backgrounding and feedlot operations. The utilization of forage resources stands as a high priority to cattle producers. Supplementation of highly digestible fiber feedstuffs can be used to enhance animal performance, to take advantage of forage resources, and to extend forages by increasing stocking rates or increasing hay production. The development of forage based beef cattle finishing systems may be supported by high-fiber energy supplementation strategies. The availability of feeder …
