At all sites, the snail populations survived the mega-tsunami in 2011 despite decreases in snail density. Changes among the genetic characteristics of each local population were verified based on nucleotide sequences of the mitochondrial DNA and microsatellites analyses. Analysis of the mitochondrial DNA revealed a decrease in genetic diversity among local populations at the mouth of the Origasa River and Ogatsu Bay, as well as a shift in the dominant sequence type found in Hitsugaura Lagoon. In contrast, microsatellite analysis revealed no genetic changes among local populations. This difference is thought to be attributable to differences in inheritance and evolutionary rates between mitochondrial DNA and microsatellites.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"東日本大震災特集論文集","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0002000332","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大気海洋研究所国際沿岸海洋研究センター","subitem_publisher_language":"ja"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12498946","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21855234","subitem_source_identifier_type":"ISSN"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"東京大学大学院新領域創成科学研究科"},{"subitem_text_language":"ja","subitem_text_value":"東京大学大気海洋研究所"},{"subitem_text_language":"ja","subitem_text_value":"岩手医科大学全学教育推進機構・教養教育センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小島, 茂明","creatorNameLang":"ja"},{"creatorName":"Kojima, Shigeaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"伊藤, 萌","creatorNameLang":"ja"},{"creatorName":"Itoh, Hajime","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"松政, 正俊","creatorNameLang":"ja"},{"creatorName":"Matsumasa, Masatoshi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-11"}],"displaytype":"detail","filename":"36_138.pdf","filesize":[{"value":"1.2MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/2000332/files/36_138.pdf"},"version_id":"abbf011d-f219-47c5-b0ca-29a502cafd49"}]},"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":"三陸海岸における巨大津波に伴うホソウミニナ個体群の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"三陸海岸における巨大津波に伴うホソウミニナ個体群の変化","subitem_title_language":"ja"},{"subitem_title":"Changes in local populations of Batillaria attramentaria after a mega-tsunami on the Sanriku Coast, Japan","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["1623392813102","1623392683554"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-06-11"},"publish_date":"2021-06-11","publish_status":"0","recid":"2000332","relation_version_is_last":true,"title":["三陸海岸における巨大津波に伴うホソウミニナ個体群の変化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T05:29:20.213716+00:00"}
