Properties of phytoplankton dynamics in such environment differed in several respects from deep eutrophic lakes. Water bloom appeard twice a year, summer and winter. Dominant species were blue-green algae such as Microcystis, Oscillatoria, Anabaena during the summer, and Chlamydomonas, Euglena in Winter. Chlorophyll a content was in a range of 140-680mg/m^2. Light saturated photosynthetic rates were almost above 10mg O_2/mg chl. a/hr (with maximum value of 24.5mg O_2/mg chl. a/hr) throughout the year. Average rate of daily gross photosynthetic production of 34.8g O_2 (13.1g C)/m^2/day recorded in the present study. This value was an upper limit of values reported in natural waters, and it was quite cloes to a value of 36.4g O_2/m^2/day which has been observed in outdoor mass cultures of Chorella. Mean annual gross production over 3 years was estimated as 4,190g O_2 (1,571g C)/m^2/year and this value was to be the highest so far encounterd in natural waters. Photosynthetic efficiency of radiation energy by phytoplankton was 3.28% for PHAR and this value may also be the highest in natural waters.","subitem_description_type":"Abstract"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1006527X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-7644","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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":[{}],"nameIdentifiers":[{"nameIdentifier":"25","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":"2013-06-26"}],"displaytype":"detail","filename":"KJ00005162141.pdf","filesize":[{"value":"968.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005162141.pdf","url":"https://honan.repo.nii.ac.jp/record/117/files/KJ00005162141.pdf"},"version_id":"4abd65d7-e0e0-479b-a2c7-d64dad28608e"}]},"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":"Some properties of phytoplankton dynamics in a shallow hypereutrophic lake, Lake Teganuma, in central Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Some properties of phytoplankton dynamics in a shallow hypereutrophic lake, Lake Teganuma, in central Japan","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["58"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-26"},"publish_date":"2013-06-26","publish_status":"0","recid":"117","relation_version_is_last":true,"title":["Some properties of phytoplankton dynamics in a shallow hypereutrophic lake, Lake Teganuma, in central Japan"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T13:18:58.245334+00:00"}
