Kenneth S. Norris Rancho Marino Reserve

16 Feb, 02 AM - 17 Feb, 02 AM

Black abalone are a proposed Endangered Species. Withering disease has been responsible for major population declines in their Southern range. However, predation by another endangered species, the Southern sea otter, is also a cause of mortality. I am looking at possible relationships among the quality of available microhabitat refuges (sufficiently deep crevices), local otter density, and abalone size classes and abundance. Specifically, I am interested in whether the abalone are restricted to deep refuges in areas with high otter density. Also, are the abalone able to utilize more habitat in areas with less threat of predation and does this affect population structure?
