Sea Urchin Life History Strategies

摘要: Abstract Life history strategies are based on the characteristics of organisms that affect their fitness. Two environmental factors important in determining life strategy organisms, including sea urchins, stress, conditions reduce production and disturbance, partial or total destruction biomass. Disturbance includes predation. Different different associated with combinations levels stress disturbance. The hypothesis these particular habitats was tested by predicting where urchins would occur. considered (the deep sea, Antarctic waters, tropical reef flats, kelp forests seagrass beds) differ Species were found predicted habitats. Recognition species is basic to understanding biology ecology. Knowledge extant useful for paleobiological paleoecological studies. Strategies have implications fisheries management, conservation evaluation aquaculture. Habitats may be expected change ocean warming acidification. response urchin changes vary strategy.
