Research Interests:
My research has focused on factors affecting population and community dynamics of freshwater fish and invertebrates, especially the role of disturbance in community dynamics, impacts of introduced species in aquatic ecosystems, and aquatic ecosystem conservation. My recent research includes examining, 1) the effect of drought and episodic drying on stream fish and invertebrate population and community dynamics, 2) effects of stream drying on fish and invertebrate refuge use and species persistence at multiple spatial and temporal scales, 3) influence of drying on fish and crayfish consumers and how they in turn affect stream ecosystem structure and function, 4) the relationship between land use, flow regime, habitat complexity and fish assemblage structure, 5) the impact of introduced species on native species, and 6) the influence of abiotic and biotic factors on habitat selection by stream fish and crayfish. As part of this work, I attempt to bridge the gap between studies done at small spatial scales and the larger spatial scales necessary to understand how disturbance and movement affect population and community dynamics in stream ecosystems.
These projects and related work are carried out using a combination of observation, experimentation in the field and lab, and modeling approaches.
