Greene (Rosaceae), along an altitudinal gradient in the Tateyama Range, Toyama Prefecture, central Japan. We also observed the change in leaf traits under simulated environmental amelioration using an open-top chamber (OTC). Three study sites were established at different altitudes (1900-2800m a. s. l.) and the OTC was installed at the highest elevation site. Snow-free duration and foliage period decreased with altitude. The number of compound leaves per shoot and individual leaf size (compound leaf area) significantly decreased, resulting in reduction of leaf mass per shoot with altitude. LMA decreased, while leaf N increased significantly with altitude. Under simulated environmental amelioration (increased temperature), number of leaves, individual leaf size, and leaf mass per shoot increased significantly. LMA showed significantly higher values and leaf N lower values in the OTC manipulated shoots compared with controls. In other words, leaf mass and LMA decrease and leaf N increases under harsh conditions. These variations and changes in leaf traits seemed to be adaptive responses to severe growth conditions to maintain positive carbon balance.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006168","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11327019","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Biosphere Science, Faculty of Science, Toyama University/Department of Biosphere Science, Faculty of Science, Toyama University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-02-01"}],"displaytype":"detail","filename":"KJ00000045412.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000045412","url":"https://nipr.repo.nii.ac.jp/record/6168/files/KJ00000045412.pdf"},"version_id":"8e53f750-0772-48d2-9e5b-9a9c44da4be8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"altitudinal gradient","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"deciduous leaf","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"leaf nitrogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LMA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"OTC","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Variations of leaf traits of an alpine shrub Sieversia pentapetala along an altitudinal gradient and under a simulated environmental change","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Variations of leaf traits of an alpine shrub Sieversia pentapetala along an altitudinal gradient and under a simulated environmental change"}]},"item_type_id":"1","owner":"4","path":["795"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-02-01"},"publish_date":"2001-02-01","publish_status":"0","recid":"6168","relation_version_is_last":true,"title":["Variations of leaf traits of an alpine shrub Sieversia pentapetala along an altitudinal gradient and under a simulated environmental change"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:05:42.309065+00:00"}
