The lapse rate of mean temperature based on the regression from upper three meteorological stations (521m, 747m, 916 m) was 0.47 ℃/100m, while the lapse rate estimated from the data of lower three stations (Om, 368m, 521m) was 0.90℃/. The duration of time when the relative humidity was over 95～100% was high above 521m (cloud zone), while it was relatively short at lower elevations under 368m. Floristic composition and relative basal area (RBA) for tree layer (trees height≧1.3m) at five study plots (P1:911m, P2:769m, P3:521m, P4:375m, and P5:59m) were alalyzed to demarcate several similar groups by using the cluster analysis (group averaging method). Five study plots were grouped into three community types, (1)Machilus kobu/Cyathea tuyamae type (521-911m a.s.l.), (2) Elaeocarpus syrvestris/Boninia grisea type (375m a.s.l.) and (3) Planchonella obovata/Melia azedarach type (59m). At the summit basal area (60.7m^2/ha) was high with a stunted tree shape (6.0m in tree height), probably due to strong wind and frequent cloud conditions. Species richness and diversity (Shannon's H') of vascular epiphyte at elevations over 521 m a.s.l. was high (14 species and 1.982, respectively) compared with lower elevations. The wet conditions of the cloud zone of the island should support the cloud forest co-dominated by evergreen trees of Machilus kobu and endemic tree-fern of Cyathea tuyamae with numerous vascular epiphytes.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"首都大学東京小笠原研究委員会"}]},"item_3_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110007145062"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110007145062","subitem_relation_type_select":"URI"}}]},"item_3_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"朱宮, 丈晴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高山, 浩二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤田, 卓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加藤, 英寿"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-03"}],"displaytype":"detail","filename":"20001-33-005.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20001-33-005.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2318/files/20001-33-005.pdf"},"version_id":"5716a560-0342-4917-a07a-65e84dfe9cc2"}]},"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":"南硫黄島における垂直分布にそった雲霧の形成と植生パターン(<特集>南硫黄2007)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南硫黄島における垂直分布にそった雲霧の形成と植生パターン(<特集>南硫黄2007)"}]},"item_type_id":"3","owner":"3","path":["482"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2318","relation_version_is_last":true,"title":["南硫黄島における垂直分布にそった雲霧の形成と植生パターン(<特集>南硫黄2007)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:39:19.159570+00:00"}
