Developing population models to examine mortality impacts and spatial components of sea otter demographics (Hosted by NCEAS)

Principal Investigators:

Leah R. Gerber

The Southern sea otter population has recovered from near extinction over the last 100 years. The slow recovery rate in California (5% annually) compared to Alaskan populations (17-20%), suggests that the southern population is highly vulnerable to emerging mortality problems (e.g., disease) and ecological disasters (e.g., oil spills). Over the last 3-5 years, recovery of the southern sea otter population has ceased and abundance has declined. By 1999, the population declined approximately 12% from its peak in 1995. This decline has been accompanied... more
