In 1929,\nthe transparency showed 26.8m by a Secchi disk and the appearances of plankton were also very\nrare. In 1963-1966 obtervations, the transparency was between 11m and 5.5m and it was 7.5m in\naverage. On the other hand, plankton volume increased remarkably, showing vivid seasonal\nvariations every year. Some dominant species are as follows.\nMelosira italica, Melosira granurata, Suriella, Fragillaria, Staurastrum asterias, Staurastrum spp. Pediastrum duplex, Bosmina longirostris, Bosmina coregoni, Cyclops strennus, Thermocyclops hyalinus, Acanthodiaptomus pacificus, and many kinds of Rotatoria such as Asplanchna, Brachionus, Synchaeta.\nThis abundance of plankton in recent years may be used as an indicator showing that Lake\nIkeda is changing gradually from oligotrophic to eutrophic lake in these forty years.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"663","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"村山, 三郎","creatorNameLang":"ja"},{"creatorName":"MURAYAMA, Saburo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"税所, 俊郎","creatorNameLang":"ja"},{"creatorName":"SAISHO, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN00040498_v16_p29-33.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040498_v16_p29-33.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10885/files/AN00040498_v16_p29-33.pdf"},"version_id":"55194ef4-a2ad-4a02-a084-ecdef0180d24"}]},"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":"池田湖のプランクトンについて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"池田湖のプランクトンについて","subitem_title_language":"ja"},{"subitem_title":"Seasonal Variations of Planktons at Lake Ikeda","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["40","4857"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-22"},"publish_date":"2015-06-22","publish_status":"0","recid":"10885","relation_version_is_last":true,"title":["池田湖のプランクトンについて"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-30T01:11:24.569068+00:00"}
