Particularly, we investigated a structure and function of pair dance. Our\nobservation in Kushiro region, Hokkaido, suggested that red-crowned cranes use various signals in\nsocial and reproductive contexts. We found that characteristics of the pair dances were related to\nreproductive success, but the results were not always consistent with the predictions. Dance\nduration increased as the breeding season approached. However, the past reproductive success of an\nindividual was negatively related to dance coordination (i.e., mutual information) of a pair. These\nresults partially support the pair bond hypothesis, but more importantly, also suggest the need to\ndefine the vague concept of a “pair bond” in a biologically reasonable, measurable way.","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-16K14806/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"動物行動学"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"挑戦的萌芽研究"}]},"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":"沓掛, 展之"}],"nameIdentifiers":[{},{},{}]}]},"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":"16K14806seika.pdf","filesize":[{"value":"136.4 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/6124/files/16K14806seika.pdf"},"version_id":"beaa33bd-348d-47e8-b46a-f95cb72ef98c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"タンチョウ","subitem_subject_scheme":"Other"},{"subitem_subject":"ダンス","subitem_subject_scheme":"Other"},{"subitem_subject":"行動生態","subitem_subject_scheme":"Other"},{"subitem_subject":"コミュニケーション","subitem_subject_scheme":"Other"},{"subitem_subject":"信号","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":"タンチョウの求愛ダンス：計算統計学による構造理解と内分泌同調仮説の検証","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"タンチョウの求愛ダンス：計算統計学による構造理解と内分泌同調仮説の検証"},{"subitem_title":"Pair dance in red-crowned cranes: structure and function","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":"6124","relation_version_is_last":true,"title":["タンチョウの求愛ダンス：計算統計学による構造理解と内分泌同調仮説の検証"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:14:24.860049+00:00"}
