Final Report for the California State Coastal Conservancy, Association of Bay Area Governments/San Francisco Bay-Delta Science Consortium, National Geographic Society and Rose Foundation. San Francisco Estuary Institute, Oakland, CA. Introduction Exotic species constitute one of the main environmental stressors in the San Francisco Estuary. To further assess the extent of this problem, we conducted a Rapid Assessment (RA) survey of exotic species at shoreline stations in San Francisco Bay in the spring of 2004.

SLOA~ ABSTRACT: Observations are reported on the feeding biolog y of Py cnopodia helianthoides (Brandt) in Barkley Sound, British Columbia, in areas ofdiffering wave exposure. Three hundred asteroids were examined; 220 were feeding on prey representing II taxa , with heaviest predation on gastropods, bivalves, and crustaceans. P. helianthoides found on soft substrates were larger than those inhabiting hard substrates. Juvenile sea stars « 5 em diameter) were found primarily at protected sites often on kelp substrate. The observed size distri­ butions of P. helianthoides may be the result of the nature of food resources available in different habitats. Significant positive correlations were obtained between sea star size and prey size except in the case of the gastropod Tegula pulligo. The possible importance of sea star predation on this snail is discussed.
