The survey area was 24.5km2, and total flight time was 9 hours and 36 minutes. It was covered by eleven flights. Four crew in a helicopter watched and counted the animals during each flight. Twenty-five sika deer, six Japanese serows and one Asiatic black bear were observed. Comparing the results of previous aerial surveys conducted here in 1987, 1988 and 1989, there was no apparent difference in the density of each species. The density of the sika deer was almost the same as that estimated by ground surveys conducted by Saitama Prefecture in 2000 and 2001. The density of the Japanese serow was lower, but we could find no reason.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54097","nameIdentifierScheme":"WEKO"}],"names":[{"name":"石田, 健"}]},{"nameIdentifiers":[{"nameIdentifier":"54098","nameIdentifierScheme":"WEKO"}],"names":[{"name":"五十嵐, 勇治"}]},{"nameIdentifiers":[{"nameIdentifier":"54099","nameIdentifierScheme":"WEKO"}],"names":[{"name":"澤田, 晴雄"}]},{"nameIdentifiers":[{"nameIdentifier":"54100","nameIdentifierScheme":"WEKO"}],"names":[{"name":"酒井, 秀夫"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森圏管理学研究室"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属秩父演習林"},{"subitem_text_value":"Laboratory of Forest Ecosystem Studies, Department of Ecosystem Studies, the University of Tokyo"},{"subitem_text_value":"University Forest in Chichibu, the University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"ISHIDA, Ken"}],"nameIdentifiers":[{"nameIdentifier":"54093","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IGARASHI, Yuji"}],"nameIdentifiers":[{"nameIdentifier":"54094","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAWADA, Haruo"}],"nameIdentifiers":[{"nameIdentifier":"54095","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAKAI, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"54096","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh109005.pdf","filesize":[{"value":"867.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh109005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25332/files/esrh109005.pdf"},"version_id":"11711ad7-fcfd-496c-be2d-d3bd15058d63"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"helicopter survey","subitem_subject_scheme":"Other"},{"subitem_subject":"Chichibu mountain","subitem_subject_scheme":"Other"},{"subitem_subject":"sika deer","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese serow","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"An Aerial Survey of Large Mammals in Chichibu Mountains, Central Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Aerial Survey of Large Mammals in Chichibu Mountains, Central Japan"}]},"item_type_id":"4","owner":"1","path":["2524","2523"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25332","relation_version_is_last":true,"title":["An Aerial Survey of Large Mammals in Chichibu Mountains, Central Japan"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:38.741857+00:00"}
