| Outline of Final Research Achievements |
There are three extant horseshoe crabs in Asia, known as a living fossil. Genetic subdivisions were detected in Japanese populations using mtDNA-AT rich marker and eight microsatellite loci. Two genetically distinct groups, the western and the eastern group were detected and the geographic boundary between these two groups is the Itoshima Peninsula, Fukuoka. Especially, population from the Iki Is., which lies in the bordering region between two genetic groups, was significantly differ from neighboring populations. I also studied about phylogenetic relationships of parasitic planarian species on Asian horseshoe crabs. The topology was almost consistent with their geographic distribution patterns. While, some region showed complicated relationships between host and parasites indicating that level of host specificity of this parasitic planarian species was not so high.
