Large animals were counted from a helicopter in Tokyo University forest in Chichibu, in the winters of 1987, 1988 and 1989. The survey area of 2,200 (1987) and 2,400 ha (1988, 1989) showed low levels of human disturbance. The densities of Japanese serow and Sika deer were 0.66-1.50/km2 and 0.33-0.88/km2 respectively, which were rather lower than the results in other areas in Japan (e. g. 2.5-5.8/km2). 2. Japanese serow was observed significantly more often on north to southeastern slopes, steeper lopes, and near valley-like terrain. Japanese serow generally prefers steep slopes. Near valley-like terrain ever-green conifers were less abundant probably making the animals easier to observe. Slope direction preference was left unexplained. 3. Sika deer was observed significantly more often at higher altitudes, on southeastern slopes, and near valley-like terrain. Annual changes in altitude and slope preference were found, valley like terrain preference was explained in the same way as with Japanese serow.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54893","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ISHIDA, Ken"}]},{"nameIdentifiers":[{"nameIdentifier":"54894","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMANE, Akiomi"}]},{"nameIdentifiers":[{"nameIdentifier":"54895","nameIdentifierScheme":"WEKO"}],"names":[{"name":"AKAIWA, Tomotoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"54896","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IGARASHI, Yuji"}]}]},"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":"東京大学農学部附属秩父演習林"},{"subitem_text_value":"筑波大学農林学系"},{"subitem_text_value":"University Forest in Chichibu, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Institute of Agriculture and Forestry, University of Tsukuba"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石田, 健"}],"nameIdentifiers":[{"nameIdentifier":"54889","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山根, 明臣"}],"nameIdentifiers":[{"nameIdentifier":"54890","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"赤岩, 朋敏"}],"nameIdentifiers":[{"nameIdentifier":"54891","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"五十嵐, 勇治"}],"nameIdentifiers":[{"nameIdentifier":"54892","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":"esrh089003.pdf","filesize":[{"value":"847.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh089003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25471/files/esrh089003.pdf"},"version_id":"78d0ee21-2248-482a-8eb0-c68f442be6b9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"大型哺乳類","subitem_subject_scheme":"Other"},{"subitem_subject":"生息密度","subitem_subject_scheme":"Other"},{"subitem_subject":"分布","subitem_subject_scheme":"Other"},{"subitem_subject":"生息環境","subitem_subject_scheme":"Other"},{"subitem_subject":"ヘリコプター","subitem_subject_scheme":"Other"},{"subitem_subject":"Large mammals","subitem_subject_scheme":"Other"},{"subitem_subject":"Density","subitem_subject_scheme":"Other"},{"subitem_subject":"Distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"Habitat","subitem_subject_scheme":"Other"},{"subitem_subject":"Helicopter survey","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"東京大学秩父演習林における冬期のカモシカ Capricornis crispus およびシカ Cervus nippon の分布","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東京大学秩父演習林における冬期のカモシカ Capricornis crispus およびシカ Cervus nippon の分布"}]},"item_type_id":"4","owner":"1","path":["2564","2563"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25471","relation_version_is_last":true,"title":["東京大学秩父演習林における冬期のカモシカ Capricornis crispus およびシカ Cervus nippon の分布"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:41.763926+00:00"}
