The objectives of this SSP project were to develop a Geographic Information System (GIS)-based habitat model for the state of Louisiana and to develop a tool for evaluating the potential effects of various land-use changes on Louisiana black bears. A habitat model previously developed to assess habitat impacts of Hurricanes Katrina and Rita on the coastal black bears in Louisiana (Murrow et al. 2012) was used as the starting point of the analysis for this study. That dataset was augmented with telemetry locations collected from 1993 to 2010 to extend and modify the original coastal model which was based on the Mahalanobis distance (D2) statistic. The goal was to then use that model to develop an estimator and user-friendly...
Human-bear conflicts are a common problem and management priority for many wildlife agencies in North America. Bears are adaptable to anthropogenic activity and food sources which creates opportunities for conflict including property damage, livestock depredation, and human injury. Acute climate events and long-term directional climate change can exacerbate human-wildlife conflict by changing resource availability, increasing overlap between humans and wildlife, and driving competition. Despite the pervasive threat that climate change poses, studies evaluating climate, human-wildlife conflict, and adaptive management strategies are limited. The goal of this work is to examine how climate variability and change have...
The Southern Appalachian Research Branch (SARB) provides research support for management of wildlife for federal lands within the Department of the Interior, including migratory species, inter-jurisdictional species, endangered species, invasive species, and species of cultural importance to Native Americans; maintaining an emphasis on upland ecosystems in the southern Appalachian Highlands. The SARB conducts research in landscape modeling to predict the ecological consequences of anthropogenic impacts to the southern Appalachians and provides expertise in wildlife habitat and population analysis with an emphasis on the management of large mammals with the goal of demonstrating concepts of sustainable wildlife population...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
