  • Purple sea urchins (Strongylocentrotus purpuratus(Stimpson, 1857)) are abundant grazing invertebrates that can have a major impact on the rocky intertidal community. Predators can control the urchin population and indirectly reduce grazing activity. We determined the effects of western gull (Larus occidentalis Audubon, 1839) predation on purple sea ur- chins in the rocky intertidal using the framework of optimal foraging theory and taking into account different prey-handling techniques. We… CONTINUE READING
