To understand impacts of climate change and land or water use on ecosystems, we must understand the physiological and behavioral impacts of shifting climate on each key member of food webs. The Power lab has, for the past 24 years, been studying river food webs of coastal California. Their work has produced detailed knowledge of interactions among organisms that channel energy fixed by river algae (Cladophora glomerata, Epithemia sp.) up through insect grazers, and sometimes to predators. Native minnows (e.g., Lavinia hesperoleucas) prey upon unarmored mobile grazers like hepatageniid and baetid mayflies (Nixe sp. and Baetis sp.). In contrast, armored mobile grazers (e.g. caddisflies, Glossosoma penitum and Dicosmoecus gilvipes) are largely invulnerable to fish predation. The outcomes of interactions among these or similar species determine in large part how trophic level biomass in rivers becomes distributed among algae, insects, and fish. Food web outcomes depend in turn on the relative performances of species, which are affected by temperature and flow regimes in speciesspecific ways. Mechanistic understanding of how temperature, flow and other environmental parameters affects physiological energetics of key web members should improve our ability to forecast ecosystem shifts that will occur in California rivers under climate change and increasing human impact.
