Summary

We propose using an existing, longterm data set of sea urchin production, sea otter performance, and ecosystem state metrics from the last 30 years tobuild a spatially explicit sea otter population viability analysis (PVA) model, incorporating climate change effects. We propose a 3-pronged approach in year 1 of this project to evaluate (obj. 1) variability in sea urchin demographics over space and time to identify scaledependent patterns of variation in production using existing datasets, (obj. 2) define the direct effects of climate change and ocean acidification on sea urchin productivity through indepth literature review and contributions from experiments by collaborators, and (obj. 3) determine how effects of environmental change [...]
