The study forest was at the Tokyo Uiversity Forest in Chiba, in the southern part of Chiba prefecture, 140°8′E, 35°9′N, ca. 300m a. s. l, 13.9℃ in annual mean temperature, and 2,230mm in annual mean precipitation, and belongs to the upper warm temperate zone. Dominant species of the upper tree-layer ranged from 13m to 21m in height were Castanopsis cuspidata var. sieboldii and Quercus acuta. Changes of the upper tree-layer during years 1976 to 1986 were slight, while those of the lower teree-layer and the forest floor vegetation were remarkable. Trees of Aucuba japonica, Dendropanax trifidus and llex rotunda less than 2m in height were abundant in 1971 and 1976, but disappeared in 1986. The coverages of Trachelospermum asiaticum, Aucuba japonica, Quercus acuta and Ardisia japonica of the forest floor vegetation in 1986 were 1/7, 1/11, 1/8 and 1/4 of those in 1971, respectively. Changes of the dominance degree were little in unpalatable species to sika deer, such as Maesa japonica, Rumohra aristata, Gleichenia japonica, Cinnamomum japonicum and Pieris japonica. The causes of decrease of palatable species were considered to be due to the population increase of sika deer (Cervus nippon) population since around 1980.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55406","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KABAYA, Hajime"}]}]},"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演習林本部"},{"subitem_text_value":"Administration Office of the University Forests, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蒲谷, 肇"}],"nameIdentifiers":[{"nameIdentifier":"55405","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":"esrh078005.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh078005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25559/files/esrh078005.pdf"},"version_id":"f609c0e8-85cf-4d9e-880b-accc5c22d37e"}]},"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":"東京大学千葉演習林荒樫沢における常緑広葉樹林の下層植生の変化とニホンジカの食害による影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東京大学千葉演習林荒樫沢における常緑広葉樹林の下層植生の変化とニホンジカの食害による影響"}]},"item_type_id":"4","owner":"1","path":["2586","2585"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25559","relation_version_is_last":true,"title":["東京大学千葉演習林荒樫沢における常緑広葉樹林の下層植生の変化とニホンジカの食害による影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:47.556696+00:00"}
