图4. 环南海区域夏季(A)和冬季(B)的红树植物扩散路线。浅灰色部分是末次盛冰期(约600万年前)海平面下降120 m后的出露陆地(Voris, 2000)。A图中的虚线表示物种迁移发生几率较低。洋流模式修改自Fang等(2012)。

Fig. 4. Main dispersal routes of mangrove plants around the South China Sea in summer (A) and winter (B). The light gray areas indicate the emerged lands in the Last Glacial Maximum (about 6 million years ago) when the sea level decreased 120 m (Voris, 2000). The dash line in A indicates limited species dispersal in the history. Ocean current patterns modified from Fang et al. (2012).
