Dr. Fisher studies the control of ecosystem structure and function using the stream-riparian system of deserts as a model. He is especially interested in the influence of long-term regimes of flood and drought in shaping streams at several levels of organization, including adaptations of organisms to disturbance, seasonal and disturbance effects on community structure, and ecosystem stability measured in terms of energy flow and nutrient cycling. Recently, Dr. Fisher and his students have been exploring the relationship between ecosystem spatial configuration and ecosystem functioning (e.g., nutrient cycling patterns, productivity, response to disturbance). Dr. Fisher teaches a graduate course in ecosystem ecology and several seminars in ecology.
