     "text": "Our ability to forecast the fate of ecosystems and species hinges on an understanding of how biological systems respond to their environment.  In this project, natural indicators of diet (stable isotopes) and production (otolith growth increment width) in two common fishes were used to investigate energy pathways and biophysical relationships in nearshore kelp forests spanning two large marine ecosystems with contrasting oceanography, the upwelling system of the California Current and the downwelling system of the Alaska Coastal Current. This study is an integral component of the USGS Pacific Nearshore Project and the data and results from this project are being used to understand differences in nearshore production from California to Alaska and the resulting population trajectories of sea otters, a keystone predator in kelp forest ecosystems and an important subsistence resource in Alaska."
