| Outline of Final Research Achievements |
This study proposes a research model for cultural ecology of mangrove with emphasis on bio-physical uniqueness as estuarine ecosystem. Mangrove Lucinids Pegophysema philippiana and Anodontia corrugate were studied for the bio-physical condition of the habitat and collector’s technique, especially their ecological knowledge. It was found that the lucinids inhabit wide range of sediments and chemical conditions, however, the P. philippiana was more abundant in sulfate-rich mud. The collectors consider the two species as two sexes of same species. Two technique were recognized; digging by hand in dry condition, and searching in water. The collectors’ organization were distinctive to respective method. Further studies of habitat structure, including water chemistries, hydrology, sediment structure, are needed to understand adaptive aspects of lucinid collecting activiries.
