The study found 38 alleles on five loci in 15 populations. The observed (H o) and expected (H e) heterozygosity values are 0.338 and 0.378, respectively. Inbreeding effect from self-pollination might explain its heterozygote deficiency. Population genetic differentiation (F ST = 0.381) was similar to other mangrove species. The genetic diversity of R. apiculata populations along the coastline inside the archipelago (e.g., Buleleng, Donggala, Mamuju, and Takalar) was higher than those of population along the coastline outside the archipelago, especially northern Sumatra populations (i.e., Langkat, Tapanuli Tengah, Dumai, and Padang). The isolation by distances and sea currents directions as well as their connectivity might affect the gene flow and genetic exchange. The more isolated with fewer connections by sea currents, the smaller gene flow and genetic exchange observed between populations. The higher genetic exchange, on the contrary, occurred when population location was closer to the meeting point of the sea currents. The study also showed that the patterns of sea current movement seemed to have influence genetic clustering of populations which fell into three main groups (Sunda Shelf Mangroves) and one isolated population (New Guinea Mangroves).1 aYahya, Andi, Fadly1 aHyun, Jung, Oh1 aLee, Jae, Ho1 aKim, Yong, Yul1 aLee, Kyung, Mi1 aHong, Kyung, Nak1 aKim, Seung-Chul  uhttps://ffa.myspecies.info/content/genetic-variation-and-population-genetic-structure-rhizophora-apiculata-rhizophoraceae
