Behaviorally Mediated Larval Transport in Upwelling Systems

Figure 6

Numerical model of larval dispersion and connectivity for larvae ( density color scale) regulating depth in four ways during the peak upwelling season (spring) in the California Current System: maintaining a depth of 5 m, maintaining a depth of 30 m, undertaking an ontogenetic vertical migration (OVM) from 5 to 30 m deep, and undertaking a diel vertical migration (DVM) from 5 to 30 m deep. Dispersion after 30 days for larvae released near Bodega Head, California (□) and connectivity after 30 to 60 days for larvae released and recruiting at sites from Palos Verdes, California, to Heceta Bank, Oregon. Diagonal line in connectivity matrices represents local recruitment with intensity above it representing poleward dispersal and intensity below it representing equatorward dispersal. Palos Verdes (PV), Point Conception (PC), Point Buchon (PB), Monterey Bay (MB), Point Reyes (PR), Point Arena (PA), Cape Mendocino (CM), Cape Blanco (CB), and Heceta Bank (HB).
