Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems

Creator:: Batchelder, Harold P., Daly, Kendra L., Davis, Cabell S., Ji, Rubao, Ohman, Mark D., Peterson, William T., and Runge, Jeffrey A.
Abstract:: The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental controls on zooplankton vital rates, especially the timing and magnitude of reproduction, growth, life-cycle progression, and mortality, determine species population dynamics, seasonal and spatial distributions,...
