Research Abstract

Mangroves are constituent plants of tropical and subtropical intertidal forest communities and they occupy about 200 million ha of areas in the world. In this study, we investigated the ecological systems of Vietnamese mangrove forests which were heavily damaged by the Vietnam War but are now regenerating and analyzed the regenerating process using population genetic approaches. The following results were obtained.
1.An investigation was conducted on Kandelia candel plantations in Namdinh Province, Northern Vietnam to elucidate the influences of stand-age and inundation on carbon accumulation in mangrove soil. We found that carbon accumulation in the soil of a plantation strongly depended upon both stand-age and inundation frequency.
2.We investigated amounts and patterns of genetic variation in mangroves of Vietnam using various markers. For K.candel and Avicennia marina, AFLP and microsatellite markers revealed that there were genetic differentiation between southern and northern populations of the two species. In fact, the extent of genetic differentiation between south and north in K.candel was so large that the two populations seemed to be from two separate species. We also used a chloroplast marker, matK, to investigate genetic differentiation adding one more common species, Lumnitzera racemosa, and obtained similar results as those based on nuclear makers except that little variation was found in L.racemosa.
Based on these results, we considered how to recover mangrove ecosystems utilizing mangrove's own regenerating capability.
