Because CWD is a new and emerging disease with a spatial distribution that had yet to be assessed in the Northeast, we examined demographic, environmental, and spatial effects to determine how each related to this spatial distribution. The objectives of our study were to identify environmental and spatial effects that best described the spatial distribution of CWD in free-ranging white-tailed deer and identify areas that support deer that are at risk for CWD infection in the Northeast. We used Bayesian hierarchical modeling that incorporated demographic covariates, such as sex and age, along with environmental covariates, which included elevation, slope, riparian corridor, percent clay, and 3 landscapes (i.e., developed, forested, open).

Global positioning system (GPS) technology for monitoring home range and movements of wildlife has resulted in prohibitively large sample sizes of locations for traditional estimators of home range. We used area-under-the-curve to explore the fit of 8 estimators of home range to data collected with both GPS and concurrent very high frequency (VHF) technology on a terrestrial mammal, the Florida panther Puma concolor coryi, to evaluate recently developed and traditional estimators.

We recently had a summary article published online. The article reviews the efforts made by regional agencies in sampling white-tailed deer for chronic wasting disease since it was first discovered in the east in 2005.

We contributed to a Special Issue "Applications of Stable Isotope Analysis in Mammalian Ecology" in Isotopes in Environmental and Health Studies. In the special issue, the first three articles report correction and discrimination factors that can be used to more accurately estimate the diets of extinct and extant mammals using stable isotope analysis. The remaining seven applied research articles use stable isotope analysis to address a variety of wildlife conservation and management questions from the oceans to the mountains.

Our lab made an online Manual of Applied Spatial Ecology to assist in research in several areas. This manual will assist researchers, biologists, students, or any interested individuals on a variety of tasks with GIS layers or data generated from research. Although we do not have datasets available that are in the manual, we hope to get this accomplished in the near future.
