| Notes | Major professor was Marcus Horning. This doctoral dissertation examines the movements and feeding behavior of Pacific harbor seals. 24 seals were captured in Netarts and Alsea Bays, tagged and tracked via satellite from Sept. 2014-Sept. 2015. A whisker from each animal was scanned to provide dietary information. “Overall, this dissertation demonstrates associations between stable isotope-derived diet and patterns in spatial habitat use, suggesting that stable isotope analysis of δ13C and δ15N can inform two-dimensional satellite telemetry, but also may provide post-hoc information regarding drivers of spatial movement of harbor seals.” This work is the “the first in-depth description of spatial habitat use for Pacific harbor seals” and represents a valuable addition to the field.
