Diversity in Coastal Systems

Our work in coastal systems focuses on how species interactions interact with abiotic factors to shape community diversity and ecosystem functioning. Beginning with a focus on non-consumptive effects, the lab's interest has grown to consider how predators, prey, competitors, and mutualists all interact with their environment to influence community composition, contributions to important ecosystem services, and outcomes of management actions. Current work includes how predators impact biogeochemical cycles in salt marshes and oyster reefs and how mutualisms in salt marshes impact marsh restoration practices.
