| Research Abstract |
Fauna of aquatic organisms in marine lakes of Palau islands was investigated to study the process of speciation and maintenance of biodiversity in marine organisms. Species assemblages of copepods, bivalves and fish were different between holomictic and meromictic lakes according to the level of isolation and local environment of the lakes. Unique morphological differentiation among the lakes was observed in bivalves. Genetic analysis revealed the past bottlenecking in populations of two fish species.
