The artificial substrata were submerged in the artificial stream which waterwas derived from the Chikuma River. The developmental pattern of periphyton expressed by chlorophyll amount was divided into two stages. A biomass change in an initial stage within two weeks was fitted with an exponential growth and then the biomass became almost constant like a batch culture except in winter. The doublingtime of biomass in the initial logarithmic stage was ranged from 1.17 days to 3.27 days. The biomass in the stationary stage was about 50 chl.a rng/m' in summer and fall. The developomental pattern of the biomass in winter was not seen the stationary phase. The biomass in winter reached 200 chl.a rng/ton 20 days after setting the substrata. It increase dlineary until the end of observation of 20 days. The biomass of periphyton was determined with the balance of the growth of periphyton and the grazing pressure by aquatic animals.","subitem_description_type":"Abstract"}]},"item_11_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_11_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"環境科学年報19:89-94(1997)","subitem_description_type":"Other"}]},"item_11_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学環境科学研究会"}]},"item_11_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-7492","subitem_source_identifier_type":"ISSN"}]},"item_11_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1054947X","subitem_source_identifier_type":"NCID"}]},"item_1627890728808":{"attribute_name":"出版タイプ","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":"中本,  信忠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桜井,  恭士"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本,  満寿夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部,  信一郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"19-13.pdf","filesize":[{"value":"420.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19-13.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/16825/files/19-13.pdf"},"version_id":"082333d2-f220-4373-83fd-741b3c4b66ef"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"付着藻類"},{"subitem_subject":"成長速度"},{"subitem_subject":"千曲川"},{"subitem_subject":"periphyton"},{"subitem_subject":"growth rate"},{"subitem_subject":"Chikuma river"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"千曲川中流部での人工付着板による付着藻類群集の発達過程","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"千曲川中流部での人工付着板による付着藻類群集の発達過程","subitem_title_language":"ja"},{"subitem_title":"DEVELOPMENTAL P ATTERN OF PERIPHYTON ON THE ARTIFICIAL SUBSTRATUM IN THE CHIKUMA RIVER","subitem_title_language":"en"}]},"item_type_id":"11","owner":"1","path":["1648"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-04-19"},"publish_date":"2011-04-19","publish_status":"0","recid":"16825","relation_version_is_last":true,"title":["千曲川中流部での人工付着板による付着藻類群集の発達過程"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-18T02:26:58.634046+00:00"}
