A migrant bird, the barn swallow, is reported to be\nresident sometimes, and our own survey showed this can be happen in Japanese barn swallows. We are\ncurrently writing a manuscript to report the effect of migration on phenotype in the barn swallows.\nAlso, we focused on the Pacific swallows, which are resident species, and found natural selection\non several phenotypic traits during once-in-a-century severe winter. This study clarified strong\nselection on non-migratory species.","subitem_description_type":"Abstract"}]},"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/grant/KAKENHI-PROJECT-17K15193/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"行動生態学"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"若手研究（B）"}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2018"}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷川, 克"}],"nameIdentifiers":[{"nameIdentifier":"11250","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-07"}],"displaytype":"simple","filename":"17K15193seika.pdf","filesize":[{"value":"96.1 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/6125/files/17K15193seika.pdf"},"version_id":"8633d34f-5241-4003-bd26-3c6c94dc03fe"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"性選択","subitem_subject_scheme":"Other"},{"subitem_subject":"渡り","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":"都市の温暖化が招く渡りの消失と集団多様化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"都市の温暖化が招く渡りの消失と集団多様化"},{"subitem_title":"Loss of migration habit and population divergence via urban warming","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-07"},"publish_date":"2020-07-07","publish_status":"0","recid":"6125","relation_version_is_last":true,"title":["都市の温暖化が招く渡りの消失と集団多様化"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:14:26.212466+00:00"}
