Short Biography

 

   


Dr. Nathaniel (Than) P. Hitt is a Research Fish Biologist in the Aquatic Ecology Branch of the U.S. Geological Survey’s (USGS) Leetown Science Center in Kearneysville, West Virginia.  He holds a B.A. in Biology from the College of Wooster, an M.S. in Organismal Biology and Ecology from the University of Montana, and a Ph.D. in Fisheries and Wildlife Sciences from Virginia Tech.  Dr. Hitt’s research investigates freshwater fish ecology and community ecotoxicology from a landscape perspective, focusing on stream ecosystems in the Appalachian highlands.  His research includes:


  • Stream network modeling of fish habitat and population/community responses to environmental change

  • Forecasting effects of climate change for fish habitat in headwater streams

  • Ecological indicators for human epidemiology

  • Environmental controls of selenium bioaccumulation in stream communities

  • Effects of stream flow and temperature on fish communities and native brook trout population dynamics
