Julie Thayer, Ph.D.

Julie has worked in the California Current marine ecosystem for the past 18 years. She did undergraduate work in marine biology at the University of California at Santa Cruz and Long Marine Lab, and obtained a Ph.D. in Marine Ecology from the University of California at Davis. Julie has conducted research on a variety of top marine predators and their prey in relation to ocean climate. She organized a group of researchers around the North Pacific Rim (Japan, Canada, U.S.) for a comparative study of forage fishes eaten by the seabird rhinoceros auklet, focusing on spatio-temporal synchronicity in connection with local to basin-scale marine variability (Thayer et al. 2008). Julie also led a Collaborative Fisheries Research project in which scientific data on the diet of salmon is collected in partnership with local recreational and commercial fishers, providing data to help understand the recent salmon population crash (Thayer et al. 2014). She is currently focusing on forage fish management strategies and incorporation of predator needs.
