Dispersal similarly shapes both population genetics and community patterns in the marine realm

摘要: Dispersal plays a key role to connect populations and, if limited, is one of the main processes maintain and generate regional biodiversity. According neutral theories molecular evolution biodiversity, dispersal limitation propagules population stochasticity are integral shaping both genetic community structure. We conducted parallel analysis biological connectivity at levels in marine groups with different traits. compiled large data sets structure (98 benthic macroinvertebrate 35 planktonic species) biogeographic (2193 734 species). estimated distances from (i.e., FST vs. geographic distance) β-diversity level. ranked same order levels, as predicted by organism ability seascape connectivity: macrozoobenthic species without dispersing larvae, followed larvae plankton (phyto- zooplankton). This ranking associated constraints movement macrozoobenthos within seabed compared pelagic habitat. showed that similarly determines degree communities populations, supporting predictions biodiversity patterns.
