Only little had been known about the land molluscan fauna on Minami-Iwo-To, and this is the first survey that intends to explore details of the land molluscan fauna of Minami-Iwo-To. Nine species were newly recorded, and in total 13 species were distributed on Minami-Iwo-To. Among these species, four were possible new species that were endemic to Minamji-Iwo-To. High species diversity of land mollusca was found at the summit of the island, whereas no speices was found at the coastal area, A species Ptychalaea dedecora tamagonari formerly distributed on Chichijima but became extinct before WWII was discovered by the present survey. The species found on Minami-Iwo-To included species that were not distributed on the Ogasawara Islands but the same or closely related species were distributed on the Izu Islands. Accordingly, land molluscan fauna on Minami-Iwo-To includes elements that are not found in the Ogasawara Islands, and is biogeographically unique and important fauna.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"首都大学東京小笠原研究委員会"}]},"item_3_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110007145060"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110007145060","subitem_relation_type_select":"URI"}}]},"item_3_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"千葉, 聡"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-03"}],"displaytype":"detail","filename":"20001-33-011.pdf","filesize":[{"value":"812.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20001-33-011.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2324/files/20001-33-011.pdf"},"version_id":"cc3275e7-f7fa-4868-89c1-46a0474342e2"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"南硫黄島の陸産貝類相(<特集>南硫黄2007)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南硫黄島の陸産貝類相(<特集>南硫黄2007)"}]},"item_type_id":"3","owner":"3","path":["482"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2324","relation_version_is_last":true,"title":["南硫黄島の陸産貝類相(<特集>南硫黄2007)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:39:10.369972+00:00"}
