The Bracken lab group, now based in the Department of Ecology and Evolutionary Biology at the University of California, Irvine, uses an interdisciplinary approach to evaluate the linkages between marine communities and ecosystems. We draw from a variety of ecological sub-disciplines, including community ecology, physiological ecology, and ecosystem ecology. Current projects in the lab address two related concepts in marine ecology that merge community and ecosystem perspectives: (1) evaluating the causes and consequences of biodiversity change and (2) quantifying the relative importance of consumers’ top-down and bottom-up effects on the growth and diversity of primary producers.
