Larry CrowderB.A., Biology and Mathematics, California State University, Fresno; M.S., Ph.D., Zoology, Michigan State University

Dr. Crowder's research centers on predation and food web interactions, mechanisms underlying recruitment variation in fishes, and on population modeling in conservation biology. He has studied food web processes in estuaries and lakes, and has used observational, experimental and modeling approaches to understand these interactions in an effort to improve fisheries management. He co-directed the South Atlantic Bight Recruitment Experiment (SABRE) and continues to conduct research on the life histories of estuarine-dependent fishes. He continues to conduct model and statistical analysis to assist in endangered species management for both aquatic (sea turtles) and terrestrial species (red-cockaded woodpeckers). Recently he has begun developing more extensive programs in marine conservation, including research on bycatch, nutrients and low oxygen, marine invasive species and integrated ecosystem management.

Crowder currently serves on the Ocean Studies Board, National Research Council, National Academy of Sciences and on the scientific steering committees for the Global Ocean Observing System (GOOS), the Global Oceanic Ecosystem Dynamics (GLOBEC) Program. He is a member of the IUCN/SSC Marine Turtle Specialists Group and head of bycatch subgroup. He is also a member of the editorial board for Ecological Applications and serves as a science advisor for the Earth & Sky Radio Series.
