I have extended this theory, which originally concentrated on kinship between two individuals, to incorporate interactions of more than two individuals. For that purpose, I have generalized genetic relatedness for two individuals to a higher order one which represents genetic similarity of three individuals or more. As an application, I have studied quorum sensing, a form of microbial communication by chemical signals. I have shown that quorum sensing evolves under the existence of high genetic relatedness between individuals.","subitem_description_type":"Abstract"}]},"item_2_description_18":{"attribute_name":"科研費研究者番号","attribute_value_mlt":[{"subitem_description":"50517802 | https://kaken.nii.ac.jp/ja/search/?qm=50517802","subitem_description_type":"Other"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"科学研究費補助金研究成果報告書\n研究代表者：大槻 久［総合研究大学院大学先導科学研究科助教］ ","subitem_description_type":"Other"}]},"item_2_relation_11":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN（科学研究費補助金データーベース）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-23870009/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"生物学、生態・環境"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"研究活動スタート支援"}]},"item_2_text_21":{"attribute_name":"科研費の分科・細目","attribute_value_mlt":[{"subitem_text_value":"基礎生物学、生態・環境"}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2013"}]},"item_2_version_type_12":{"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":"大槻, 久"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-08"}],"displaytype":"simple","filename":"23870009seika_ohtsuki.pdf","filesize":[{"value":"233.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"研究成果報告書","url":"https://ir.soken.ac.jp/record/5643/files/23870009seika_ohtsuki.pdf"},"version_id":"93b9368e-4bd8-4b52-b26c-857847849458"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"協力の進化","subitem_subject_scheme":"Other"},{"subitem_subject":"血縁度","subitem_subject_scheme":"Other"},{"subitem_subject":"血縁淘汰","subitem_subject_scheme":"Other"},{"subitem_subject":"進化ゲーム","subitem_subject_scheme":"Other"},{"subitem_subject":"クオラムセンシング","subitem_subject_scheme":"Other"},{"subitem_subject":"coalescence","subitem_subject_scheme":"Other"},{"subitem_subject":"集団遺伝学","subitem_subject_scheme":"Other"}]},"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":"高次血縁度から理解する社会性進化理論","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高次血縁度から理解する社会性進化理論"},{"subitem_title":"Social evolution theory via higher order relatedness","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-08"},"publish_date":"2017-12-08","publish_status":"0","recid":"5643","relation_version_is_last":true,"title":["高次血縁度から理解する社会性進化理論"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:56:12.363862+00:00"}
