| Abstract | The Indonesian Archipelago accommodates the largest mangrove area in Southeast Asia and possesses the world's richest composition of mangrove species. The archipelago comprises areas of the biogeographic regions Sunda and Wallacea, separated by Wallace's line. We used the true mangrove species Lumnitzera littorea and L. racemosa as a study case for understanding the effects of phylogeographic history, sea surface currents and geographical distance on genetic diversity and genetic structure. We sampled 14 populations of L. littorea (N = 106) and 21 populations of L. racemosa (N = 152) from Indonesia. We utilized 3,442 biallelic SNP loci genotyped with the ddRADseq approach. We assessed genetic diversity, genetic structure, and effective dispersal of the populations, and related them to geographical distance and sea surface currents. Our study revealed low levels of genetic variation at population level in Lumnitzera. Pronounced genetic differentiation between populations indicated two phylogroups in both species. While in L. littorea the two phylogroups were largely separated by Wallace's line, L. racemosa showed a northwest vs. southeast pattern with strong mixture in Wallacea. Our findings provide novel insights into the phylogeography of the mangrove genus Lumnitzera and the role of sea surface currents in the Indonesian Archipelago. |
