John is currently a postdoctoral researcher working with Colden Baxter in the ISU Stream Ecology Center and Emma Rosi-Marshall at the Cary Institute of Ecosystem Studies. He received his B.Sc. from the University of Florida and Ph.D. from the University of Georgia. His doctoral research studied the effects of long-term nutrient enrichment on macroinvertebrate food webs in a detritus-based headwater stream. As a postdoctoral researcher, John has continued his interest in studying the effects of land-use and global change on macroinvertebrate food web structure and function. In collaboration with researchers from ISU and various other research institutions, he is currently addressing the effects of global climate change on food webs and ecosystem processes within the Salmon River Basin, Idaho. Because climate change within this ecoregion is predicted to alter forest communities via changes in fire and precipitation regimes, these stream ecosystems may experience a substantial alteration of their abiotic and biotic template. By resampling study sites along the Salmon River that were originally a part of the River Continuum Project, this large-scale comparative approach will help assess whether recent shifts in climatic, hydrologic and fire regimes have altered the Salmon River’s functional state. As the Salmon River is relatively unimpacted and unregulated, this research will allow us to better understand how large unregulated rivers may respond to future global climate change.
