Research Contribution to Society:

Biodiversity is the variety of life-- from genes to species to ecosystems. My research examines the links between this diversity and the stability and productivity of coastal marine ecosystems. Human activities in the coastal zone are altering biodiversity in many ways, and natural processes cause variation in biodiversity from place to place and over time. Our work examining the consequences of diversity loss in kelp forests, estuaries, tidepools and seagrass beds allows for better conservation, management and restoration of these habitats. Our work on understanding the processes that maintain diversity also informs our ability to predict the consequences of invasion by exotic species for native ecosystems.

Research Interests:

Marine Community and Evolutionary Ecology
The unifying theme of my research is the ecological causes and consequences of biodiversity. I have found seaweeds and marine invertebrates to be particularly tractable experimental subjects and have conducted research involving a diverse suite of invertebrate taxa including corals, hydroids, crabs, echinoderms, polychaetes, ascidians, bryozoans, and gastropods. The main issues my research has focused on are the effects of species diversity on communities and ecosystems, the ecological consequences of genetic diversity, positive interactions and mutualisms, the ecology and evolution of decorator crabs, and biological invasions.
