  • 1) Movement ecology, migration, philopatry, and transmitter effects of overwintering duck populations –collaboration with Ducks Unlimited, Delta Waterfowl, US Fish and Wildlife Service, Sitka Foundation, Tennessee Tech University, Louisiana Department of Wildlife and Fisheries, Arkansas Game & Fish Commission, Missouri Department of Conservation, Osage Basin Foundation, Bass Pro Shops, and private industry.
  • 2) Bottomland hardwood stand structure and composition influencing mallard habitat use. – collaboration with Five Oaks Ag Research & Education Center, Sturgis Foundation, US Fish and Wildlife Service.
  • 3) Lipid reserves and body condition of overwintering waterfowl in the Mississippi Alluvial Valley – collaboration with US Fish and Wildlife Service, Forbes Biological Station, Christian Brothers University, and Ducks Unlimited.
  • 4) Overwintering waterfowl use of climate-smart commodities from hardwood restoration for small and underserved landowners.
  • 5) Emergent marsh wetland: secretive marsh bird occupancy, remote sensing to assess vegetation change to drawdowns, and emergent marsh benefits to waterfowl. – collaboration with Lower Mississippi Alluvial Valley Joint Venture, Arkansas Audubon, U.S. Fish and Wildlife Service.
