Research Interests

The purpose of our research program is to better understand the dynamics and structure of populations and communities of nearshore coastal marine ecosystems. The underlying themes of this research are two-fold; firstly, to further our conceptual understanding of “open” populations and communities by conducting empirical studies motivated by the evolving theory for these systems, and secondly, to apply these concepts to fisheries and conservation problems in innovative ways. Our approach is to integrate empirical studies conducted in the field and laboratory with the development of ecological theory, including models.

In coastal marine ecosystems we are exploring the relative roles of, and relationships between, nearshore oceanographic and habitat features, larval supply, settlement and post-settlement processes (e.g., competition and predation) that influence the structure and dynamics of marine populations and communities. We are also interested in how structural features of reef habitats influence such biotic interactions. To date, most of this work has focused on populations and assemblages of temperate and tropical reef fishes. We are also exploring ways to apply such basic ecological information to the conservation and harvest of marine species, including marine reserves, artificial reefs and environmental impact assessment.

In coastal freshwater ecosystems we are exploring the biotic and abiotic processes that influence the structure and dynamics of salmonid populations. Graduate students are co-funded and co-advised with ecologists at the NOAA Fisheries – Santa Cruz Laboratory here at the Long Marine Lab campus.
