Abstract Recent and future coastal habitat degradation climate change can result in the loss of genetic diversity, especially Southeast Asia. Despite its economic importance for agar industry, phylogeography intertidal red alga Gracilaria salicornia from Vietnam remains unexplored. Here we used 399 mitochondrial COI sequences, including 55 newly generated Vietnam, to decipher phylogeographic pattern G. . The phylogeny haplotype network revealed presence three haplogroups Haplogroup I, comprising 18 haplotypes, predominantly inhabited west South China Sea, while haplogroup II, consisting eight haplotypes Japan Philippines, likely reflecting influence Kuroshio Current. A single Philippines was placed III. exhibited high with neutrality test, mismatch distribution, Bayesian skyline plot suggesting a sudden demographic or range expansion during mid-Pleistocene. divergence I occupying eastern western sides resulted sea currents glacial sea-level changes. Our study on historical offers valuable insights that will encourage further research into population history tropical algae Asia, region remarkable marine biodiversity.

Understanding population genetic connectivity is crucial for the sustainability and persistence of marine biodiversity. As a fundamental reef-building macroalga coastal ecosystem, Halimeda macroloba Decaisne one dominant intertidal seaweeds in Indo-Pacific region. However, its structure have been poorly recognized. Here, we explored H. using chloroplast tufA, rps3-rpl14, rbcL. Our results indicated low diversity shallow at intraspecific level, uncovering five groups with six subdivided lineages tufA two clusters rps3-rpl14. We detected demographic expansion last glacial period Pleistocene significantly asymmetric gene flow among different geographical units. suggest that southwestward ocean currents under influence northeast monsoon region are main factor shaping present structure, asexual reproduction also plays an important role pattern; addition, divergence between might be related to historical isolation led by paleoclimate oscillation Pleistocene. The Xisha Islands northern South China Sea serve as potential refugium macroloba, which needs extra attention conservation management. Given limitation sample size, need conduct more field work carry out further research larger scale future. study provided new insights into theory scientific basis tropical costal seaweed conservation.
