Abstract


GENETIC CONNECTIVITY IN SCLERACTINIAN CORALS IN THE GULF OF THAILAND

Coral recovery from natural and anthropogenic disturbances is highly influenced by the pattern and strength of connectivity among populations through dispersal of planulae which are much variable. The population genetic studies provide important information that can be applied for managing marine protected areas and their networks. Knowledge of genetic connectivity is useful for understanding of the recovery potential of coral populations after various disturbances, especially mass coral bleaching. The aim of this study was to examine population genetic patterns in the coral Pocillopora damicornis at certain locations in the Gulf of Thailand by using microsatellite markers. The results clearly showed that high genetic similarity among populations over 300 kilometers was detected. It may be the consequences of long competency periods of brooded zooxanthellate larvae and multiple larval release events each year. Therefore, some level of connectivity appears to be maintained between reef sites in the Gulf of Thailand. Life history traits may influence the genetic structure of coral populations. Further studies should investigate genetic connectivity in certain scleractinian corals in the Gulf of Thailand.
