Effects of five southern California macroalgal diets on consumption, growth, and gonad weight, in the purple sea urchin Strongylocentrotus purpuratus
Consumer growth and reproductive capacity are direct functions of diet. Strongylocentrotid sea urchins, the dominant herbivores in California kelp forests, strongly prefer giant kelp (Macrocystis pyrifera), but are highly catholic in their ability to consume other species. The biomass of Macrocystis fluctuates greatly in space and time, and the extent to which urchins can use alternate species ...
متن کاملWave disturbance overwhelms top-down and bottom-up control of primary production in California kelp forests.
We took advantage of regional differences in environmental forcing and consumer abundance to examine the relative importance of nutrient availability (bottom-up), grazing pressure (top-down), and storm waves (disturbance) in determining the standing biomass and net primary production (NPP) of the giant kelp Macrocystis pyrifera in central and southern California. Using a nine-year data set coll...
متن کاملEcological role of purple sea urchins.
Sea urchins are major components of marine communities. Their grazing limits algal biomass, and they are preyed upon by many predators. Purple sea urchins (Strongylocentrotus purpuratus) are among the best studied species. They live in environments that alternate between two stable states: luxuriant, species-rich kelp forests and sea urchin-dominated "barrens." The transition from one state to ...
متن کاملThe Effects of Predators and Habitat on Sea Urchin Density and Behavior in Southern California Kelp Forests
OF THE THESIS The Effects of Predators and Habitat on Sea Urchin Density and Behavior in Southern California Kelp Forests by Kathryn D. Nichols Master of Science in Biology San Diego State University, 2009 It is well documented that sea urchins can have vast impacts on kelp forest community structure as a result of kelp grazing. Despite the ecological importance of sea urchins, direct field stu...
متن کاملEcosystem effects of fishing in kelp forest communities
Kelp forests, highly diverse cold water communities organized around the primary productivity and physical structure provided by members of the Laminariales, support a variety of fisheries, and the kelp itself is harvested for alginates. Worldwide, these communities generally share susceptibility to destructive overgrazing by sea urchins. The impact of sea-urchin grazing is governed by the rati...
