Dispersal distance distributions as simulated by the high-resolution biophysical model of the north-western Mediterranean. Relative frequencies of binned (30 km bin-width) larval dispersal distances for (a) white seabream (Diplodus sargus, magenta), (b) red mullet (Mullus surmuletus, orange), and (c) comber (Serranus cabrilla, turquoise) reveal that dispersal is occurring most frequently at short distances around 15 km, but long-distance dispersal events with secondary peaks between 300 and 400 km related to the advection of larvae with ocean currents in the order of 0.1 m s⁻¹ are also captured. These results are consistent with the combination of restricted and long-distance dispersal suggested by the empirical and simulated genetic data. (Online version in colour.)
