Cummins, K W

The research continued to focus on three general areas: validation of the macroinvertebrate functional feeding group (shredders, collectors, scrapers and predators) method of stream ecosystem analysis; preparation of major reviews of the functional group system of analysis and a field key for the use of the procedure by a wide variety of groups having different levels of expertise; and, demonstration of the interactive importance of food quality (defined in terms of macroinvertebrate growth) and temperature on stream invertebrate growth and survival. The validation procedure involves light and scanning electron microscope analysis of the food acquisition morphology, biochemical analysis, and food resource-specific responses of selected representative species.
