Landscape genetics and CWD in white-tailed deer
… in infected areas can facilitate predictions of CWD spread via deer dispersal. We analyzed microsatellite genotypes of white-tailed deer populations in southern Wisconsin and Illinois to quantify population level movements, genetic admixture and gender-biased dispersal patterns using FST and …

An Analysis of the Ecology and Public Perception of Coarse Woody Debris in Virginia
Coarse woody debris (CWD) is an important habitat component for wildlife, fish, and plants and is important in nutrient cycling and soil formation. Knowledge of the volume, distribution, and use of CWD across Virginia would be useful to forest managers modeling nutrient budgets in southeastern …

Landscape Ecology of Chronic Wasting Disease in Virginia, USA
… across landscapes. Chronic wasting disease (CWD) is a neurodegenerative disease in the deer family Cervidae caused by a prion, a pathogenic and misfolded variant of a naturally occurring protein. Managing and controlling CWD is imperative for conservation of ecologically and economically …

Potential of above- and below-ground coarse woody debris as a carbon sink in managed and unmanaged forests
… an increase in the stock of coarse woody debris (CWD). CWD represents a short- to middle term C sink that is of particular importance in natural and old-growth forests. Its impact on the soil organic carbon (SOC) stock is largely unknown. To investigate the impact of management, a case study was …

Timing recombinant prion protein conversion as a measure of prion activity in chronic wasting disease
Chronic Wasting Disease (CWD) is a fatal neurological disease affecting cervids caused by prions. Infected cervids shed the CWD prion in bodily fluids and excrement, contaminating the environment and creating an agricultural and ecological calamity. Preclinical antemortem CWD testing method is …

Chronic wasting disease as a model for the development of risk communication using the mental models approach
<p>Using chronic wasting disease (CWD) as a model for risk communication development using the mental models approach, this dissertation examines: 1) how published CWD risk communications compare to expert recommendations; 2) whether the experts and members of relevant stakeholder groups agree upon …

Investigating genetic vulnerability to chronic wasting disease in endangered cervid taxa
Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE). TSEs are a group of progressive neurodegenerative diseases caused by prions. Prions are misfolded infectious proteins with a stable altered structure that allows them to induce conformational changes in normal …

Hunters' responses to chronic wasting disease: specialization, social trust, and perceived risk
Chronic wasting disease (CWD) is found in deer, elk, and moose in several states and provinces. CWD causes abnormal behavior, emaciation, and death in all infected animals. Although CWD has not caused human health problems, transmission to humans cannot be dismissed. Little is known about the …

Coarse Woody Debris in Industrially Managed Pinus taeda Plantations of the Southeastern United States
Coarse woody debris (CWD) plays an influential role in forested ecosystems by adding organic matter to soils, stabilizing the soil environment, providing wildlife habitat, preventing soil erosion, providing seedling establishment habitat, and involvement in the nutrient cycle. Most CWD research has …

DOUBLE SAMPLING FOR COARSE WOODY DEBRIS ESTIMATIONS FOLLOWING LINE INTERSECT SAMPLING
Coarse woody debris (CWD), an essential component of healthy forests, has typically been defined as dead and down, large woody material. Quantification of this resource provides a useful metric for assessing wildlife habitat, fuel loading, and more recently, carbon sequestration. Although many CWD …

Tree species effects on the release of dissolved organic carbon and nitrogen from decomposing logs
… to the mass loss of coarse woody debris (CWD comprising all dead woody material with at least >7 cm in diameter). Increased DOC and nitrogen (N) inputs into the forest floor can be expected from CWD. Since the fate of leached DOC depends on its biodegradability, the latter might play a …

Monitoring for Chronic Wasting Disease in Mule Deer and White-Tailed Deer at Wind Cave National Park: Investigating an Emerging Epizootic
Chronic wasting disease (CWD) has emerged as a disease of concern in cervid populations. Testing, transmission, and detection of CWD are areas of interest for managing populations of North American deer (Odocoileus). This dissertation addresses these areas with research from data collected on mule …

Effects of edge and coarse woody debris on small mammal communities in riparian and upland habitats in northern West Virginia
… communities to edge and coarse woody debris (CWD) volume in riparian and upland habitats of the central Appalachian Mountains has received little attention. The objectives of this study were to: (1) Perform a faunal survey of the Camp Dawson Collective Training Area in Preston County, West …

Principals' perceptions related to transition to kindergarten for children with disabilities: A mixed methods study
To ensure children with disabilities (CWD) have a successful transition to kindergarten, teachers have been encouraged to use high-intensity, or individualized, transition practices. Yet, while limited or lack of administrator support has been cited as a barrier to transition practice use, there …
