AB: The physical template strongly influences ecosystem processes in streams. Among the physical properties exerting control on ecosystem processes are discharge regime, substratum characteristics, light levels, and water flow paths at both the channel and catchment scales. Ecosystem processes such as whole-system rates of metabolism and reach-scale nutrient cycling respond to variations in these physical properties at several temporal scales. This talk will explore these physical template-ecosystem process linkages via several examples from studies of small streams.
