Alexander Huryn received a Ph.D. in Entomology from the University of Georgia in 1986 and completed his postdoctoral research at the University of Alabama in 1991. He was appointed Associate Professor at the University of Alabama in 2003. He has been a Professor at the University of Alabama since 2008.
I am a freshwater ecologist with a strong interest in how local, landscape, and regional factors affect the structure and productivity of stream communities. These factors may be physical, such as stream channel form, water temperature or periods of wetting, drying and freezing, or biological, such as differences in food sources or food-web structure. I have found that stream productivity is usually controlled by several factors that operate simultaneously, often in complex and surprising ways. A predictive understanding of such factors and their interactions is critical for making sound decisions concerning the management and restoration of stream communities. In addition to my academic interests, I am also a committed field naturalist who has been lucky enough to have worked extensively in some truly spectacular streams in the Smoky Mountains, southern New Zealand, Panama and Arctic Alaska. My most recent research has focused on Arctic streams in the vicinity of the Toolik Field Station in Alaska. This region supports a remarkable diversity of stream types. Here my students and I have been using habitat-template theory to gain understanding of how landscape attributes control stream food-web complexity and productivity at both the catchment and regional scales.
