Molecular　analyses revealed that exotic genome, probably of domestic alien species origin, was detected in populations of the two species in the Ise Bay basin. In one of the populations, with exotic genome introgressed at high frequency, the ratio of hybrid between the two species was high. In this population, not only F1 but also BC were observed, together with individuals with mismatch between nuclear and mitochondrial genomes. Contrary to females, infertility was suggested in F1 males, likely warranting the persistence of both the species, irrespective of high hybridization. Although introgression of exotic genome was high in hybrids, direct relationship between the genome and hybridization was not detected, with the sigh of effects of man-made habitat change on hybridization.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2020年度～2022年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"20K06813","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","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":"河村, 功一","creatorNameLang":"ja"},{"creatorName":"Kawamura, Kouichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"古丸, 明","creatorNameLang":"ja"},{"creatorName":"Komaru, Akira","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-28"}],"filename":"2024RP0106.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","url":{"label":"2024RP0106.pdf","url":"https://mie-u.repo.nii.ac.jp/record/2001018/files/2024RP0106.pdf"},"version_id":"055e4bc3-7a13-4d66-b052-3e0546eb9c24"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"国内外来種","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝的攪乱","subitem_subject_scheme":"Other"},{"subitem_subject":"種間関係","subitem_subject_scheme":"Other"},{"subitem_subject":"生殖的隔離","subitem_subject_scheme":"Other"},{"subitem_subject":"系統地理","subitem_subject_scheme":"Other"},{"subitem_subject":"種間交雑","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝子浸透","subitem_subject_scheme":"Other"},{"subitem_subject":"棲み分け","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"国内外来種の侵入による在来種群の消滅のメカニズムの解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"国内外来種の侵入による在来種群の消滅のメカニズムの解明","subitem_title_language":"ja"},{"subitem_title":"Mechanism of extinction of indigenous species community by the invasion of domestic alien species","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1728958246114"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-28"},"publish_date":"2024-10-28","publish_status":"0","recid":"2001018","relation_version_is_last":true,"title":["国内外来種の侵入による在来種群の消滅のメカニズムの解明"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-10-28T02:44:50.405909+00:00"}
