Observing southern sea otter foraging behavior from San Nicolas Island, California.
Julie Yee
Dr. Julie Yee is a Research Statistician with the Western Ecological Research Center (WERC).
Since 1997, she has used statistics and biometry for WERC to quantitatively analyze and interpret a variety of aspects of wildlife and plant population dynamics, such as recruitment, growth, survival, and wildlife movement. Her research has been applied to study the effects of renewable energy, contaminants, fire, and other influences on wildlife populations and ecosystems. She is currently a PI at the Santa Cruz field station where she supervises continued work on sea otter and nearshore research.

Observing southern sea otter foraging behavior from San Nicolas Island, California.
Equipment used during a shore-counted portion of the annual range-wide sea otter census. On the clipboard is a paper map, with sea otter locations, numbers, behavior and habitat recorded, as well as some other environmental variables. The spotting scope is used to view sea otters that are far away, and binoculars are used to scan areas for otters.
