Dr. Laura Rogers-Bennett completed her Ph.D. in Ecology at the University of California, Davis and two post-doctoral fellowships one at U.C. Santa Cruz’s, Institute of Marine Science and the other at the U. Washington’s, Friday Harbor Labs. Dr. Rogers-Bennett is a Research Associate with the Karen C. Drayer Wildlife Health Center at the University of California, Davis and a Senior Environmental Scientist with the California Department of Fish and Wildlife in the Marine Region. She is based at the UC Davis, Bodega Marine Lab where she leads a team investigating marine ecosystem health and invertebrate populations, fishery management and marine conservation. To do this work they use an interdisciplinary approach combining field, laboratory and quantitative modeling to examine questions related to wildlife health, ecosystem tipping points, marine conservation biology, fisheries sustainability and climate change. She has over 50 scientific publications and 10 book chapters on marine issues. She is also a co-PI working on the restoration of the critically endangered white abalone in California. She established a 20-year underwater marine ecosystem monitoring program and has documented the impacts of climate change and the massive marine heat wave of 2014-2015 on kelp forests and abalone resources in northern California.

Marine Invertebrate Fisheries and Conservation Laboratory

Research 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.

Laura Rogers-Bennett holds concurrent positions at the California Department of Fish and Wildlife and the UC Davis Wildlife Health Center and is based at the Bodega Marine Laboratory.
