Fig. 1From: Historical isolation and contemporary gene flow drive population diversity of the brown alga Sargassum thunbergii along the coast of ChinaTwo biogeographic patterns for intertidal species in Yellow-Bohai Sea and East China Sea. Lineage distribution and neighbor-joining tree were redrawn from (a) Sargassum horneri [4] and (b) Sargassum fusiforme [16]. Shaded sea areas are continental shelves that would have been exposed to the air during periods of low sea level. CDW: Changjiang diluted water.
