title: Comparative phylogeography of the incipient species <em>Sargassum polycystum</em> and <em>S. plagiophyllum</em> around the Thai-Malay Peninsula

description: There are 20 files uploaded. Eight files correspondingly contain four
 datasets of Sargassum plagiophyllum populations (mtDNA cox1, mtDNA cox3,
 mtDNA cox1+cox3, nrDNA ITS2) and the identified mtDNA haplotypes or nrDNA
 ribotypes for each dataset. The other four files contain four datasets of
 Sargassum polycystum populations (mtDNA cox1, mtDNA cox3, mtDNA cox1+cox3,
 nrDNA ITS2) and the identified mtDNA haplotypes or nrDNA ribotypes for
 each dataset. The remaining three files contain the combined
 haplotype/ribotype datasets of S. plagiophyllum and S. polycystum,
 together with the haplotypes/ribotypes dataset of S. polycystum from
 Hainan-Guangxi, China. There is an Excel file that describes how the
 sampling localities of several S. plagiophyllum populations correspond to
 their abbreviations used for molecular analysis in the manuscript.
