Comparative phylogeographic patterns and processes of the incipient brown seaweeds <i>Sargassum polycystum</i> and <i>S. plagiophyllum</i> around the Thai-Malay Peninsula.

ABSTRACT: Incipient (recently-evolved) species are morphologically distinct and have a relatively short evolutionary history from a common ancestor, yet comparative phylogeographic patterns of incipient seaweed species have seldom been explored. Here, we created 339 mitochondrial cox1, 339 cox3, 339 cox1+cox3 and 286 nuclear ITS2 sequences for Sargassum plagiophyllum (10 populations) and 326 cox1, 336 cox3, 310 cox1+cox3 and 341 ITS2 sequences for S. polycystum (14 populations) around the Thai-Malay Peninsula (TMP), with the aim to explore potential drivers in shaping population genetic structuring and diversity over space, including a phylogeographic signature of incipient speciation. Comparative analysis showed that the two S
