Taxonomy and biogeography on deep-sea mussels inhabited in deep-sea chemosynthetic ecosystem

1. 3.参加2004年在Lau盆地执行的Shinkai 6500号潜水巡航，并对深海贻贝Bathymodiolus breviator Cosel、Metivier和Hashimoto进行取样，1994.4.从Kaikata海山热液喷口采集的深海贻贝的形态分析。该结果在<th>日本海洋科学技术厅组织的第20届新海研讨会上公布如下：（2004）穴居深海贻贝的形态分析。5. 2005年，发表了关于Kaikata海山深海贝类的穴居描述论文如下：6.巴布亚新几内亚马努斯海盆深海贝类的形态分析。该结果在<th>日本海洋科学技术厅组织的第22届新海研讨会上公布如下：（2006年）对马努斯盆地喷口深海贻贝的形态分析。7.南延世穹丘喷流口和菊海岛渗漏口深海贝类的形态分析。经鉴定，这两种贻贝分别属于巨贻贝属（Gigantidas）和Bathymodiolus aduloides Hashimoto and Okutani，1994，均为未描述的贻贝，今后将继续进行同样的研究。

1.The compilation and organization of the literature on deep-sea mussels.2.The acquisition of image processing system and deep freezer for morphologic and genetic studies on deep-sea mussels.3.Participation of the Shinkai 6500 dive cruise executed at the Lau Basin in 2004 and sampling deep-sea mussel, Bathymodiolus brevior Cosel, Metivier and Hashimoto, 1994.4.Morphologic analysis on deep-sea mussels collected from a hydrothermal vent site of the Kaikata Seamount. The result was posted at the 20^<th> Shinkai Symposium organized by Japan Agency of Marine Science and Technology as follows ;Hashimoto, J.(2004) Morphologic analysis on burrowing deep-sea mussels. The abstract papers of the Shinkai Symposium, 20 : 69.5.In 2005, the description paper of burrowing deep-sea mussels from the Kaikata Seamount was published as follows ;6.Morphologic analysis on deep-sea mussels collected from the Manus Basin, Papua New Guinea. The result was posted at the 22^<th> Shinkai Symposium organized by Japan Agency of Marine Science and Technology as follows ;Hashimoto, J.(2006) Morphologic analysis on deep-sea mussels from a vent site on the Manus Basin. The abstract papers of the Shinkai Symposium, 22: 80-81.The result is under submitted to a scientific journal.7.Morphologic analysis on deep-sea mussels from a vent site on the Minami-Ensei Knoll and a seep site off Kikaijima Island. The mussels were identified as undescribed mussels belonging to the genus Gigantidas and Bathymodiolus aduloides Hashimoto and Okutani, 1994, respectively.Same studies will be continued from now on.
