Marine Resource Assessment Laboratory

Photo: LAura Rogers-BennettResearch in the Marine Resource Assessment Laboratory focuses on addressing processes that impact marine populations and communities then applying these findings to fishery management and marine conservation issues. We work primarily with benthic marine invertebrates inhabiting nearshore rocky-reef ecosystems. In this work, we integrate field, experimental and modeling approaches to understand and examine theory related to population and community-level dynamics. We are currently working on projects investigating (1) the potential role of climate change on fished intertidal populations, (2) modeling approaches to describe growth, survival and reproduction in red abalone, (3) quantifying baseline abundances of depleted abalone species, (4) indirect effects of fishing ecosystem engineers, (5) the role of marine reserves as control areas for fishing impacts and (6) sensitivity analyses of matrix population models for fished and endangered species.
