(Graduate students register for 272H.) This course incorporates the approaches of experimental ecology, biomechanics (ecomechanics), and physiology to develop an integrated perspective on the factors that govern the structures of marine ecosystems and how environment change, including anthropogenic influences, affects ecosystems' species composition and health. Focus is on rocky intertidal, kelp forest, estuarine, and midwater ecosystems of Monterey Bay. Experimental projects done in the field offer experience in a variety of ecological techniques and in analysis of ecological data. Students will engage in presentation and debates of current topics in marine ecology and conservation. Satisfies Central Menu Area 4 for Bio majors.
