Abstract
Knowledge of the amount and patterns of genetic variation within and among populations of mangrove trees is essential for devising optimum genetic management strategies for their conservation and sustainable utilization. Ceriops tagal is a widespread viviparous mangrove. Genetic diversity in the species was examined with inter-simple sequence repeat (ISSR). Nine natural populations were collected from Thailand and China. The estimates of genetic variation were extremely low (HT = 0.0179 ± 0.005, HS = 0.0084 ± 0.001), and only 47% of the total gene diversity was maintained within populations (GST = 0.529). The eastern coastal populations of Thailand were more similar to populations from China than to populations from the western coastline of Thailand. A high level of Nei's genetic identity exists between populations of C. tagal (I = 0.989), suggesting their common ancestry. The low levels of genetic diversity in the species may result from a series of genetic bottlenecks during several glacial epochs.
