The stations were characterized by distinctive sediment characteristics (Station A, sandy sediment with low sulfide content; Station B, muddy and sulfide-rich sediment). Soft tissues of the consumers exhibited much more depleted δ^<34>S values (+3.2 to +12.1‰) than those of dissolved sulfate in the water column (+20.6 to +20.8‰). The value for each species was 1.6 to 5.3‰ lower at Station B than at Station A. These results suggest the assimilation of sulfides in the sediment (δ^<34>S; -23.2 to -22.7‰) via microbial trophic pathways. In this lagoon, benthic microalgae and/or other microbes in the sediment are the most probable ^<34>S-depleted food source for the consumers. Interspecies variations in δ^<34>S values are explained by the different dietary contribution of the ^<34>S-depleted diets versus ^<34>S-enriched phytoplankton and are closely related to different feeding habits (i.e., surface-deposit feeding, facultative suspension feeding, and obligatory suspension feeding).","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類","subitem_description_type":"Other"}]},"item_4_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"},{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"760503 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大学東北アジア研究センター"},{"subitem_publisher":"publisher"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1343-9332","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11158374","subitem_source_identifier_type":"NCID"}]},"item_4_text_72":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Center for Northeast Asian Studies, Tohoku University / Biological Institute, Graduate School of Science, Tohoku University / Faculty of Humanities and Social Sciences, Iwate University / Center for Northeast Asian Studies, Tohoku University / Faculty of Agriculture, Iwate University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KANAYA, Gen"}],"nameIdentifiers":[{"nameIdentifier":"126277","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NOBATA, Ei"}],"nameIdentifiers":[{"nameIdentifier":"126278","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MAKI, Yonosuke"}],"nameIdentifiers":[{"nameIdentifier":"126279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KIKUCHI, Eisuke"}],"nameIdentifiers":[{"nameIdentifier":"126280","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MIZOTA, Chitoshi"}],"nameIdentifiers":[{"nameIdentifier":"126281","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":"2017-02-20"}],"displaytype":"detail","filename":"KJ00005127337.pdf","filesize":[{"value":"760.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005127337.pdf","url":"https://tohoku.repo.nii.ac.jp/record/51157/files/KJ00005127337.pdf"},"version_id":"42147341-3718-4c15-ba36-d5743a644309"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Stable isotope ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"Sulfur","subitem_subject_scheme":"Other"},{"subitem_subject":"Infaunal animals","subitem_subject_scheme":"Other"},{"subitem_subject":"Sulfate-reducing bacteria (SRB)","subitem_subject_scheme":"Other"},{"subitem_subject":"Food source","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Low sulfur isotopic signatures (δ^<34>S) of macrozoobenthos from a brackish lagoon: contribution of microbially reduced sulfides","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Low sulfur isotopic signatures (δ^<34>S) of macrozoobenthos from a brackish lagoon: contribution of microbially reduced sulfides"}]},"item_type_id":"4","owner":"3","path":["307"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"51157","relation_version_is_last":true,"title":["Low sulfur isotopic signatures (δ^<34>S) of macrozoobenthos from a brackish lagoon: contribution of microbially reduced sulfides"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T23:28:28.368895+00:00"}
