Results from analysis of molecular variance (AMOVA) in four intertidal and subtidal species. For each species, locations were divided into two groups (Yellow Sea group and East plus South China Seas group) according to the Yangtze River Estuary. Reference: Cellana toreuma, Dong et al. [20]; Sargassum horneri, Hu et al. [36]; Atrina pectinata, Liu et al. [37]. **P < 0.01, ***P < 0.001
