Avian ecology, wildlife biology, conservation biology
My research strives to improve species conservation and monitoring programs, and the management of protected areas, through a better understanding of wildlife habitat relationships and sampling methods. Central to that research has been the application of ecological principles to the conservation of rare, endangered, or declining species and their habitats. Research is focused in three broad areas: (1) understanding the ecological factors that constrain species diversity and abundance, (2) modeling wildlife habitat relationships at the population and landscape level, and (3) improving wildlife population sampling methods. Studies have contributed to the restoration of endangered Bald Eagles and Hawaiian and Black-capped Petrels, and the conservation of American Oystercatchers on the Outer Banks of North Carolina. Models of wildlife habitat relationships inform the conservation and management of Neotropical migratory landbirds on their breeding grounds in southern Appalachian forests, and at migratory stopover habitats along the Gulf Coast. Recent experimental studies of the factors affecting detection probability on auditory point count surveys for birds and frogs help practitioners account for previously unknown sources of uncertainty in nationwide population monitoring programs such as the Breeding Bird Survey and the North American Amphibian Monitoring Program.
