| Outline of Final Research Achievements |
The influence that Arian specie of land snail in Islands gives in endemic ecosystem. The influence that Arian specie of land snail in Islands gives in endemic ecosystem was investigated. In a habitation investigation into Achatina fulica, In Amami Oshima Island, the habitat of A.fulica was limited to a house and field neighborhood or a nature strip irregularity. It was elucidated quantitatively that A. fulica did not invade the natural forest. There is A.d.osumiensis, A.d.kikaiensis, A.d.despecta and A.d.herklotsi in Acsta despecta as subspecis. These four spp understood what they could not distinguish at the DNA level. Acsta despecta is strong in an artificial dispersing tendency. However, the course of the act of man dispersion understood that elucidation was difficult even if I examined it at a DNA level.
