A total of 270 individuals of eight species (seven native and one exotic species) were captured in the study area. Japanese medaka was predominant fish in the irrigation-ditch. The density and population size of medaka were estimated at 4.9 individuals per ㎡ and ca. 9,000～12,000 individuals, respectively. Comparisons of the population data between successive years suggested that the medaka population around paddy fields had drastically decreased after abandonment of cultivation.","subitem_description_type":"Abstract"}]},"item_10_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_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学教育学部附属志賀自然教育研究施設研究業績 (40): 29-32(2003)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学教育学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-9128","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11520449","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"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":"北野,  聡","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山形,  哲也","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"市川,  寛","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林,  尚","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-24"}],"displaytype":"detail","filename":"Shiga40-04.pdf","filesize":[{"value":"396.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Shiga40-04.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/2224/files/Shiga40-04.pdf"},"version_id":"2f93948f-be23-4794-837b-ab28f285ef90"}]},"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":"長野県北部の水田用水路に生息する淡水魚類：耕作放棄1年後の状況","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長野県北部の水田用水路に生息する淡水魚類：耕作放棄1年後の状況","subitem_title_language":"ja"},{"subitem_title":"Population density of Japanese medaka Oryzias latipes in an irrigation-ditch around abandoned paddy fields in the northern Nagano prefecture, Japan.","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["238"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-27"},"publish_date":"2009-02-27","publish_status":"0","recid":"2224","relation_version_is_last":true,"title":["長野県北部の水田用水路に生息する淡水魚類：耕作放棄1年後の状況"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-02-08T01:59:00.356842+00:00"}
