Their autumnal color becomes yellow though that of the trees in the sun become red. Winged maple aphids emerging on shaded A. palmatum fly to late budding A. palmatum and lay larvae at the same time as the stem mothers. Thus intra-spcific variation of the phenology of maples caused by site conditions is great enough to allow addition of another generation for the maple aphid. In the autumn most winged aphids lay larvae mostly on trees of yellow leaves, i.e. on shaded trees. Thus, stem mothers overwinter on shaded trees every year.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55180","nameIdentifierScheme":"WEKO"}],"names":[{"name":"古田, 公人"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"FURUTA, Kimito"}],"nameIdentifiers":[{"nameIdentifier":"55179","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":"esrh082006.pdf","filesize":[{"value":"743.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh082006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25520/files/esrh082006.pdf"},"version_id":"cce11289-d577-40b5-b37b-8a6322eb9677"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"カエデ","subitem_subject_scheme":"Other"},{"subitem_subject":"生物季節","subitem_subject_scheme":"Other"},{"subitem_subject":"アブラムシ","subitem_subject_scheme":"Other"},{"subitem_subject":"日陰","subitem_subject_scheme":"Other"},{"subitem_subject":"生息場所","subitem_subject_scheme":"Other"},{"subitem_subject":"phenology","subitem_subject_scheme":"Other"},{"subitem_subject":"maple","subitem_subject_scheme":"Other"},{"subitem_subject":"budding","subitem_subject_scheme":"Other"},{"subitem_subject":"aphid","subitem_subject_scheme":"Other"},{"subitem_subject":"shade","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":"Early Budding of Acer palmatum Caused by the Shade : Intra-specific Heterogeneity of the Host for the Maple Aphid","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Early Budding of Acer palmatum Caused by the Shade : Intra-specific Heterogeneity of the Host for the Maple Aphid"}]},"item_type_id":"4","owner":"1","path":["2578","2577"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25520","relation_version_is_last":true,"title":["Early Budding of Acer palmatum Caused by the Shade : Intra-specific Heterogeneity of the Host for the Maple Aphid"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:43.798979+00:00"}
