Some caged plots were also set to estimate the dear grazing damage on seedlings. Most of ash and wingnut seedlings germinated just after the flushing of the canopy trees had completed. The survival rate of ash seedlings in caged plots was higher than one in open plots in the first year, but became lower in the second year. The survival rate of wingnut seedlings was higher in open plots than in caged plots, but most of the seedlings died by the beginning of next spring. The dear grazing would make diminution of herbs as well as the number of ash seedlings decrease. So it is probable that moderate grazing by dear may contribute to the establishment of ash seedlings escaped from grazing. The removal of herb layer may be necessary for the establishment of wingnut seedlings as well as canopy gap.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54766","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KISANUKI, Hiromitsu"}]},{"nameIdentifiers":[{"nameIdentifier":"54767","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KAJI, Mikio"}]},{"nameIdentifiers":[{"nameIdentifier":"54768","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Kazuo"}]}]},"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北海道演習林"},{"subitem_text_value":"東京大学農学部附属秩父演習林"},{"subitem_text_value":"東京大学農学部林学科"},{"subitem_text_value":"University Forest in Hokkaido, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"University Forest at Chichibu, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Department of Forest Science, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木佐貫, 博光"}],"nameIdentifiers":[{"nameIdentifier":"54763","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶, 幹男"}],"nameIdentifiers":[{"nameIdentifier":"54764","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 和夫"}],"nameIdentifiers":[{"nameIdentifier":"54765","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":"esrh093006.pdf","filesize":[{"value":"688.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh093006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25446/files/esrh093006.pdf"},"version_id":"e639e7ec-0a69-4f64-b610-040c5234afe8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"シオジ","subitem_subject_scheme":"Other"},{"subitem_subject":"サワグルミ","subitem_subject_scheme":"Other"},{"subitem_subject":"実生","subitem_subject_scheme":"Other"},{"subitem_subject":"生残過程","subitem_subject_scheme":"Other"},{"subitem_subject":"食害","subitem_subject_scheme":"Other"},{"subitem_subject":"Ash","subitem_subject_scheme":"Other"},{"subitem_subject":"Wingnut","subitem_subject_scheme":"Other"},{"subitem_subject":"Seedling","subitem_subject_scheme":"Other"},{"subitem_subject":"Survival process","subitem_subject_scheme":"Other"},{"subitem_subject":"Grazing","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":"秩父地方の山地渓畔林におけるシオジおよびサワグルミ実生の消長","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"秩父地方の山地渓畔林におけるシオジおよびサワグルミ実生の消長"}]},"item_type_id":"4","owner":"1","path":["2556","2555"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25446","relation_version_is_last":true,"title":["秩父地方の山地渓畔林におけるシオジおよびサワグルミ実生の消長"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:41.072535+00:00"}
