Macroinvertebrate samples were collected at a treatment site, created by excavation of the riverbed, over a 98 d period. We compared the density and diversity of caddisfly larvae collected at the treatment site to a control site, located upriver. Three of 10 species found at the control site were not found at the treatment site. Furthermore, the Shannon-Wiener species diversity index (H') was lower at treatment site, although the total caddisfly density was similar to the control site by Day 98. The three most abundant species at control site were Psychomyia acutipennis, Potamyia chinensis, and Hydropsyche orientalis. The density of all three species was initially low at the treatment site following the excavation (Day 1). Beginning at Day 69, the density of Ps. acutipennis began to increase at the treatment site and was more than twice as high as at the control site by Day 98. Similarly, the density of Po. chinensis increased between Day 59 and 98 but did not exceed the density at the control site. In contrast, H. orientalis was rarely observed at the treatment site. Our results suggest that large-scale removal of the riverbed affected several key physical parameters and changed the density and species diversity of the trichopteran community.","subitem_description_type":"Abstract"}]},"item_6_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_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"環動昆.20(1):17-26(2009)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Hirabayashi, Kimio","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.WpTCjekV.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本環境動物昆虫学会"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.11257/jjeez.20.17"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.11257/jjeez.20.17","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2009 by the Japanese Society of Environmental Entomology and Zoology"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-4698","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10186037","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kimura, Goro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Eiso"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirabayashi, Kimio"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-22"}],"displaytype":"detail","filename":"26460796_x07.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensefree":"© 2009 by the Japanese Society of Environmental Entomology and Zoology","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"26460796_x07.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/20475/files/26460796_x07.pdf"},"version_id":"67158fdc-32a5-4890-8513-ee8bfefeeb5b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Caddisfly","subitem_subject_scheme":"Other"},{"subitem_subject":"Diversity","subitem_subject_scheme":"Other"},{"subitem_subject":"Large-scale substrate removal","subitem_subject_scheme":"Other"},{"subitem_subject":"Recovery","subitem_subject_scheme":"Other"},{"subitem_subject":"Shinano River","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Changes in the species composition and density of caddisflies (Trichoptera) after an excavation work in the middle reaches of the Shinano River, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Changes in the species composition and density of caddisflies (Trichoptera) after an excavation work in the middle reaches of the Shinano River, Japan","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1310"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-02-22"},"publish_date":"2019-02-22","publish_status":"0","recid":"20475","relation_version_is_last":true,"title":["Changes in the species composition and density of caddisflies (Trichoptera) after an excavation work in the middle reaches of the Shinano River, Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:24:45.657789+00:00"}
