Combining genetic data with current and predicted climate scenarios, we are modeling the predicted future distributions of wildlife populations in the Arctic and identifying key environmental variables that determine important animal habitat.
Three themes of ongoing research: forecasting polar bear and walrus population response to changing marine ecosystems; measuring wildlife population changes in the Arctic coastal plain, and wildlife communities in the boreal-Arctic transition zone.
A chapter of the publication: Land Use History of North America on general patterns of plant species diversity in North America that shows how these patterns have changed over time.
Identification of epiphytes (plants obtaining moisture and nutrients from the air and rain and usually living on another plant) on seaweed in Tampa Bay, Florida. Abstract of symposium presentation with photos.
Information on USGS studies of Chesapeake Bay, the nation's largest estuary, concerned with water quality, ecosystem history and change, vital habitat and biological resources, and land use studies.

Detailed publication on the classification system for an inventory of wetlands and deepwater habitats of the United States used to describe ecological taxa and arrange them in a system useful to resource managers.
Addresses geographic range and distribution of wildlife diseases, plant and animal phenology, wildlife host-pathogen interactions, and disease patterns in wildlife.
