| Research Abstract |
Genetic diversity and population structure were analyzed in three tropical seagrass species in Nansei Islands, Japan, aiming to obtain basic information for the conservation of seagrass meadows. In two species, any conservation unit was not recognized at the populations in the islands because of the lower genetic differentiation.Instead, the low genetic diversity suggested the presence of vulnerability to global climatic change. The rest species was revealed to contain multiple distinct genetic units, which required taxonomical revision including the morphological analysis.
