Accurately measuring productive capacity in streams is challenging, and field methods have generally focused on the limiting role of physical habitat attributes (e.g. channel gradient, depth, velocity, substrate). Because drift-foraging models uniquely integrate the effects of both physical habitat (velocity and depth) and prey abundance (invertebrate(More)
Identifying causes of structural ecosystem shifts often requires understanding trophic structure, an important determinant of energy flow in ecological communities. In coastal pelagic ecosystems worldwide, increasing jellyfish (Cnidaria and Ctenophora) at the expense of small fish has been linked to anthropogenic alteration of basal trophic pathways.(More)
ii ACKNOWLEDGEMENTS We dedicate this report to the memory of Steve Foley. He was instrumental in supporting this project and without his assistance the project would not have been successful. We thank the many folks who assisted with the field work which included USFWS employees: Trout scales were analyzed at the WDFW aging lab under the direction of Lee(More)
