Marine cytheroidean ostrcaodes, which are probably most diversified taxa in ostracodes, are known for its increasing of diversity in Paleogene. The super family is proved to have paedomorphic characters against the other primitive superfamilies such as Bairdoidea and Cythpridoidea. This is seen in the number of pores in carapaces and the number of setae in brachial plates. The results are obtained from the detail observation and description of representatives from each superfamilies through ontogeny. On the other hand, four genera belonging to the superfamily cytheroidea and bairdioidea were especially studied well on the process and timing of the speciation and evolution. They were the genera Loxoconcha, Xestoleberis, Paradoxostoma of cytheroidea and the genus Neonesidea of bairdoidea, and their taxonomiy and geographical distribution were studied in Japan, Philippines and the west coast of North America. The common pattern found in the evolution of these genera lead to the conclusion that the biodiversity of related species are extgremely high around Japan compared with other areas in the world. These related species are living separately in Pacific, Sea of Japan, Okhotsk Sea and cold Oyashio areas, which corresponds to the currents and/or marine climatic divisions. The reason of this fact may be because the glacial eustatic sea level changes in the Quaternary caused the isolation of the marginal seas, and eventually a natural selection for the mutation which was able to adapt to the cold climate during glacial ages. As mentioned above, through this study, the evolutionary model which can be applicable to the isolated marginal sea area was first acquired.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:14340155, 研究期間(年度):2002-2005","subitem_description_type":"Other"},{"subitem_description":"出典：「進化パターンの普遍性と階層性-海の昆虫「貝形虫」からのアプローチ」研究成果報告書　課題番号14340155\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052602","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理工研究域地球社会基盤学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=80194976"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=80194976","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-14340155/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-14340155/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-14340155/143401552005kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-14340155/143401552005kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神谷, 隆宏"}],"nameIdentifiers":[{"nameIdentifier":"80175","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80194976","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80194976"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-01"}],"displaytype":"detail","filename":"SC-PR-KAMIYA-T-kaken 2006-11p.pdf","filesize":[{"value":"244.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-KAMIYA-T-kaken 2006-11p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46269/files/SC-PR-KAMIYA-T-kaken 2006-11p.pdf"},"version_id":"fe4ad99b-202a-4a29-8343-fd240771a8bf"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"進化パターンの普遍性と階層性: 海の昆虫「貝形虫」からのアプローチ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"進化パターンの普遍性と階層性: 海の昆虫「貝形虫」からのアプローチ"},{"subitem_title":"Universality and hierarchy in evolutionary pattern-approach from \"marine insect\" Ostracoda","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2828"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-01"},"publish_date":"2018-11-01","publish_status":"0","recid":"46269","relation_version_is_last":true,"title":["進化パターンの普遍性と階層性: 海の昆虫「貝形虫」からのアプローチ"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:31:19.185277+00:00"}
