  • NREM 5473: Stream Ecology


Research Interests
My research incorporates basic and applied research, often with a combination of field and modeling components that focus on improving the conservation and management of lotic ecosystems. My research focuses on identifying relations and mechanisms related to rare, declining, or economically-important aquatic species for which the causes and corresponding management responses are unclear. As a researcher, I am broadly interested in the conservation and management of lotic ecosystems, but primarily I conduct research related to aquatic landscape change. The ecology of stream systems is linked to principles derived from landscape ecology and the widely-held view that aquatic landscapes are nested hierarchies of interactions between terrestrial and aquatic elements. Landscape change incorporates a variety of different elements including land management, climate change, flow regulation, etc.
