Global phylogeography of a pantropical mangrove genus Rhizophora

Abstract Rhizophora is a key genus for revealing the formation process of the pantropical distribution of mangroves. In this study, in order to fully understand the historical scenario of Rhizophora that achieved pantropical distribution, we conducted phylogeographic analyses based on nucleotide seq...
