Geographic analysis of thermal equilibria: a bioenergetic model for predicting thermal response of aquatic insect communities. Progress report, July 1, 1979-June 30, 1980
This report summarizes the first 9 months of field and laboratory work to test our central hypothesis. Five river systems were selected for intensive studies on insect growth, metabolism, and fecundity as well as determination of community structure for distinct assemblages of insect species exploiting various trophic and habitat resources. Laboratory studies were initiated to test the relative importance of temperature and food quality on growth, size, and fecundity of insects. Our project is intended to test the hypothesis that population stability, within the geographic range of many stream species, reflects largely a dynamic equilibrium between temperature and individual growth, metabolism, reproductive potential, and generation time. We propose to delineate the significance of natural thermal variation by quantifying the bioenergetics, developmental dynamics, and spatial distribution of major representative groups of stream insects throughout their geographic range.
