The number of annual rings on a stump showed a broad, continuous distribution from 50 to 250. The mosaic structure, composed of even-aged patches of various phases, was not recog-nized in the spatial dispersion pattern. The diameter at breast height showed a monomodal distribution. The structure described above is presumed to be formed by two processes, 1) hiba seedlings, not only in gaps but all over the forest floor, had been given chances to survive until the next disturbance because of their abilities to tolerate closed canopies for long periods, and successors of various ages had been accumulating under such canopies, 2) these successors of small size simultaneously began rapid growths after the intensive disturbance.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72362","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUGITA, Hisashi"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本森林学会"}]},"item_16_relation_16":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002830495","subitem_relation_type_select":"URI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本森林学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-485X","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部附属演習林, (現)独立行政法人森林総合研究所"}]},"item_16_version_type_27":{"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":"杉田, 久志"}],"nameIdentifiers":[{"nameIdentifier":"72361","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":"2016-11-14"}],"displaytype":"detail","filename":"jjfs-v75n3p201-207.pdf","filesize":[{"value":"585.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jjfs-v75n3p201-207.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9230/files/jjfs-v75n3p201-207.pdf"},"version_id":"8c3a409e-7551-4eac-9a58-ca22c9505f2c"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ヒバ林の成立過程(II) : 更新パターン","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヒバ林の成立過程(II) : 更新パターン"}]},"item_type_id":"16","owner":"3","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-05"},"publish_date":"2010-11-05","publish_status":"0","recid":"9230","relation_version_is_last":true,"title":["ヒバ林の成立過程(II) : 更新パターン"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:10:01.491180+00:00"}
