The soil in the pots was perfused with either 15mm 0.015% or 0.03% H2SO4 solution or tap water once a week. After three or four months, macroinvertebrates in the soil were collected by hand sorting. Samples were divided into 14 taxa and others. The 14 taxa were Oniscidae, Armadillidiidae, Oligochaeta, Chilopoda, Diplopoda, Araneida, Carabidae, Elateridae, Scarabaeidae, Shilphidae, Staphylinidae, Dermaptera, Cynidae and Gryllotalpidae. Acidic water apparently had adverse effects on total individual numbers, total fresh weight and taxon diversity of soil macroinvertebrates. There was no significant difference in the total number of individuals found in the pots with two dosages (0.03% and 0.015%) of acidic water. Acidic water significantly decreased the individual numbers of Oniscidae (Isopoda) but increased those of Araneida. In soil covered with a litter of Quercus acutissima, both the total number of individuals and fresh weight of soil macroinvertebrates increased. The adverse effects of acidic water on macroinvertebrates were relieved by the presence of litter. With dried oil cakes and litter, both macroinvertebrate numbers and fresh weight increased further, but acidic water counteracted the effects. Macroinvertebrates belonging to the taxa which have been known to select similar environments or have similar life style selected similar environments even in this experiment.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54529","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FURUTA, Kimito"}]},{"nameIdentifiers":[{"nameIdentifier":"54530","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KUBOTA, Kohei"}]},{"nameIdentifiers":[{"nameIdentifier":"54531","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MUSYAFA"}]},{"nameIdentifiers":[{"nameIdentifier":"54532","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IWAMOTO, Norinaga"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森林科学専攻"},{"subitem_text_value":"東京大学農学部附属演習林　田無試験地"},{"subitem_text_value":"Department of Forest Science, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Experiment Station at Tanashi, The University Forests, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古田, 公人"}],"nameIdentifiers":[{"nameIdentifier":"54525","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"久保田, 耕平"}],"nameIdentifiers":[{"nameIdentifier":"54526","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ムシャファ"}],"nameIdentifiers":[{"nameIdentifier":"54527","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩本, 則長"}],"nameIdentifiers":[{"nameIdentifier":"54528","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh098002.pdf","filesize":[{"value":"928.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh098002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25405/files/esrh098002.pdf"},"version_id":"00f1780a-4ee6-48fb-9fda-8da42326f650"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"リター","subitem_subject_scheme":"Other"},{"subitem_subject":"ワラジムシ類","subitem_subject_scheme":"Other"},{"subitem_subject":"オサムシ類","subitem_subject_scheme":"Other"},{"subitem_subject":"クモ類","subitem_subject_scheme":"Other"},{"subitem_subject":"油かす","subitem_subject_scheme":"Other"},{"subitem_subject":"Litter","subitem_subject_scheme":"Other"},{"subitem_subject":"Oniscidae (Isopoda)","subitem_subject_scheme":"Other"},{"subitem_subject":"Carabidae","subitem_subject_scheme":"Other"},{"subitem_subject":"Araneida","subitem_subject_scheme":"Other"},{"subitem_subject":"Oilcake","subitem_subject_scheme":"Other"}]},"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":"人工酸性雨が大型土壌動物に与える影響とリターの有無","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"人工酸性雨が大型土壌動物に与える影響とリターの有無"}]},"item_type_id":"4","owner":"1","path":["2546","2545"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25405","relation_version_is_last":true,"title":["人工酸性雨が大型土壌動物に与える影響とリターの有無"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T04:59:50.550952+00:00"}
