Jonathan Horton, PhD

306 Zeis Hall
Office hours are open door and by appointment.

Dr. Horton's research focuses on plant physiological ecology, especially the response of plants to abiotic and biotic stressors. His research has taken him from the southern Appalachian Mountains to the Sonoran Desert and back again. Most recently, Dr. Horton has been collaborating with scientists from Virginia Tech and the U.S. Forest Service investigating the mechanisms by which evergreen understory shrubs inhibit tree regeneration, including both above- and belowground resource limitation. This research has included molecular identification of mycorrhizal colonists on oak seedlings. Future research plans include investigations of characteristics that make invasive species successful and the interplay between mycorrhizae and their plant symbionts.
