During the colder period (November to March), BA and BP were not significantly correlated through the water column, indicating that top-down effects controlled bacterial abundance. In contrast, BA was significantly positively correlated with BP during the warmer period (April to October). The ratio of the estimated potential grazing rate of nanoflagellates to BP during the colder period tended to be greater than that during the warmer period. The change of BA/HNFA suggested that HNF populations did not immediately reduce BA as much as might have been expected during the warmer period. The low values of BA/HNFA during the warmer period also suggested that predation effects were more important in regulating the population dynamics of HNF relative to bottom-up control by the bacterial food supply.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040701","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Environment and Information Science, Yokohama National University, Japan"},{"subitem_text_value":"Ecological Research Center, Kyoto University, Japan"},{"subitem_text_value":"Ocean Research Institute, University of Tokyo, Japan"},{"subitem_text_value":"International Coastal Research Center, Ocean Research Institute, University of Tokyo, Japan"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"BAKI, Mohammad Abdul"}],"nameIdentifiers":[{"nameIdentifier":"139258","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MOTEGI, Chiaki"}],"nameIdentifiers":[{"nameIdentifier":"139259","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SHIBATA, Akira"}],"nameIdentifiers":[{"nameIdentifier":"139260","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"FUKUDA, Hideki"}],"nameIdentifiers":[{"nameIdentifier":"139261","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SHIMODE, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"139262","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KIKUCHI1, Tomohiko"}],"nameIdentifiers":[{"nameIdentifier":"139263","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":"2017-06-27"}],"displaytype":"detail","filename":"CMS330104.pdf","filesize":[{"value":"875.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS330104.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40710/files/CMS330104.pdf"},"version_id":"44847b02-7f1f-4dfc-82b6-f1b1cdd22131"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bacteria","subitem_subject_scheme":"Other"},{"subitem_subject":"bottom-up","subitem_subject_scheme":"Other"},{"subitem_subject":"chlorophyll a","subitem_subject_scheme":"Other"},{"subitem_subject":"HNF","subitem_subject_scheme":"Other"},{"subitem_subject":"top-down","subitem_subject_scheme":"Other"},{"subitem_subject":"virus","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":"Temporal changes in chlorophyll a concentrations and bacterial, viral, and heterotrophic nanoflagellate abundances in the coastal zone of Sagami Bay, Japan: implications of top-down and bottom-up effects","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal changes in chlorophyll a concentrations and bacterial, viral, and heterotrophic nanoflagellate abundances in the coastal zone of Sagami Bay, Japan: implications of top-down and bottom-up effects"}]},"item_type_id":"4","owner":"1","path":["7191","7189"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-05-28"},"publish_date":"2010-05-28","publish_status":"0","recid":"40710","relation_version_is_last":true,"title":["Temporal changes in chlorophyll a concentrations and bacterial, viral, and heterotrophic nanoflagellate abundances in the coastal zone of Sagami Bay, Japan: implications of top-down and bottom-up effects"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:18.345871+00:00"}
