| Outline of Final Research Achievements |
In this study, we conducted a survey on the distribution of Unionoida mussels in the northern part of Kyushu, clarified the physical conditions necessary for maintaining their habitat, and investigated the purpose of contributing to conservation of biodiversity in the floodplain environment.
As a result, we clarified the present situation of the distribution of Unionoida mussels in the northern part of Kyushu. It has revealed that Unionoida mussels are extremely rare and urgent. Relationship between distribution of mussels and the physical environment of habitat shows that concrete revetment of agricultural canals is the largest limiting factor. In order to maintain habitat of the mussels, it showed that it is necessary to regenerate the point where redeposition can be expected due to preservation of supply point and diffusion from supply source.
