摘要: To investigate the biological and physical mechanisms affecting larval dispersal, we embedded a model of Balanus glandula development behavior into circulation fields waters along central California coast. Physical were generated by three-dimensional ocean with horizontal resolution 1.5 km 20 topography-following layers in vertical. The was forced air–sea fluxes derived from mesoscale atmospheric assimilated temperature salinity data Autonomous Ocean Sampling Network II experiment. An ecosystem that calculated chlorophyll (a proxy for food concentration) also coupled to model. development, behavior, concentration, used run simulations dispersal. Simulation results predicted greater return larvae nearshore relaxation patterns than upwelling. More supplied coast north Monterey Bay south, successfully returned generally had limited dispersal distances. These modeling agree previous observations B. population dynamics California.
