Particularly I focused on individual heterogeneity caused by a within-individual process of social trajectory (i.e., transition among life history stages including age, natal dispersal, reproduction, dominance rank,　and so on). I employed multiple methods including fieldwork, behavioral observation, physiological measurements, phylogenetic comparative analyses on multiple species of mammals, and found results that fit predictions from adaptive theories.\n", "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（科学研究費助成金データベース）"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://kaken.nii.ac.jp/search/?kw=%E5%93%BA%E4%B9%B3%E9%A1%9E%E3%81%AB%E3%81%8A%E3%81%91%E3%82%8B%E5%80%8B%E4%BD%93%E3%81%AE%E7%A4%BE%E4%BC%9A%E7%9A%84%E5%A4%89%E9%81%B7%EF%BC%9A%E8%A1%8C%E5%8B%95%E6%88%A6%E7%95%A5%E3%83%BB%E9%81%A9%E5%BF%9C%E5%BA%A6%E3%83%BB%E5%80%8B%E4%BD%93%E7%BE%A4%E5%8B%95%E6%85%8B%E3%82%92%E8%A7%A3%E6%98%8E%E3%81%99%E3%82%8B%E7%B5%B1%E5%90%88%E7%94%9F%E6%85%8B%E5%AD%A6", "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（A）"}]}, "item_2_text_5": {"attribute_name": "報告年度", "attribute_value_mlt": [{"subitem_text_value": "2017"}]}, "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": "沓掛, 展之"}], "nameIdentifiers": [{"nameIdentifier": "10753", "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": "2019-04-10"}], "displaytype": "simple", "download_preview_message": "", "file_order": 0, "filename": "25711025seika.pdf", "filesize": [{"value": "161.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 161000.0, "url": {"label": "研究成果報告書", "url": "https://ir.soken.ac.jp/record/5927/files/25711025seika.pdf"}, "version_id": "f54f087e-8d0e-4fe9-8a34-7d54ce2d958c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "哺乳類", "subitem_subject_scheme": "Other"}, {"subitem_subject": "社会", "subitem_subject_scheme": "Other"}, {"subitem_subject": "生活史", "subitem_subject_scheme": "Other"}, {"subitem_subject": "行動生態学", "subitem_subject_scheme": "Other"}, {"subitem_subject": "血縁淘汰", "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": "哺乳類における個体の社会的変遷：行動戦略・適応度・個体群動態を解明する統合生態学", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "哺乳類における個体の社会的変遷：行動戦略・適応度・個体群動態を解明する統合生態学"}, {"subitem_title": "Individual social trajectory in mammals: integration of behavioral strategies, fitness, and population dynamics", "subitem_title_language": "en"}]}, "item_type_id": "2", "owner": "24", "path": ["34", "115"], "permalink_uri": "https://ir.soken.ac.jp/records/5927", "pubdate": {"attribute_name": "公開日", "attribute_value": "2019-04-10"}, "publish_date": "2019-04-10", "publish_status": "0", "recid": "5927", "relation": {}, "relation_version_is_last": true, "title": ["哺乳類における個体の社会的変遷：行動戦略・適応度・個体群動態を解明する統合生態学"], "weko_shared_id": -1}
