The Bracken lab group 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.
