The mangroves (Rhizophora mucronata, R. apiculata and Bruguiera gymnorrhiza) assimilate light sulfur (^<32>S) (δ^<34>S=-14.4 to -6.2‰) from among sulfides in the substrate sediments (^<34>S=-20.3 to -11.9‰). The sulfides derive from the reduction of seawater sulfate by activity of sulfate-reducing bacteria under an ample supply of organic matter from mangrove trees. The gastropods (Terebralia palustris, T. sulcata and Telescopium sp.), which feed on the litter of the associated mangroves at low tide, have low δ^<34>S values ranging from -2.5 to +9.5‰ in their soft tissues. The present data indicates that of the sulfur assimilated by these species, 40-70‰ is derived from mangroves, with the remainder coming from sulfates in ambient seawater (δ^<34>S=+21‰), the absolute end-member of sulfur reservoir for marine organisms. The isotopic data provide an overall figure for sulfur nutrition that is difficult to estimate by conventional observation. The common bivalve (Anadara sp., δ^<34>S=+10.3‰) and a gastropod (Strombus (Euprotomus) aurisdianae, δ^<34>S=+14.4‰) obtained from areas of no vegetation in the peripheral regions of the mangrove forests also indicate assimilation of isotopically light sulfur. The isotopically light sulfur would be derived from mangrove leave litter as suspended detritus.","subitem_description_type":"Other"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The malacological society of Japan"}]},"item_16_relation_16":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110004773557/en","subitem_relation_type_select":"URI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The malacological society of Japan"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"},{"subitem_rights":"本著作物の著作権は日本貝類学会に帰属します。ご利用に当たっては著作権法ならびに日本貝類学会に従うことをお願いいたします。"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348-2955","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Research Fellow of the Japan Society for the Promotion of Science, Institute of Geoscience, University of Tsukuba"},{"subitem_text_value":"Faculty of Agriculture, Iwate University"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","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":"Yamanaka, Toshiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mizota, Chitoshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"vjmsj-v60n1-2p71-78.pdf","filesize":[{"value":"672.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"vjmsj-v60n1-2p71-78.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9173/files/vjmsj-v60n1-2p71-78.pdf"},"version_id":"38305419-d63f-417e-b158-5fd87a2627fe"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gastropod","subitem_subject_scheme":"Other"},{"subitem_subject":"bivalve","subitem_subject_scheme":"Other"},{"subitem_subject":"mangrove forest","subitem_subject_scheme":"Other"},{"subitem_subject":"sulfur nutrition","subitem_subject_scheme":"Other"},{"subitem_subject":"sulfur isotope","subitem_subject_scheme":"Other"},{"subitem_subject":"feeding habitat","subitem_subject_scheme":"Other"}]},"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":"Sulfur Nutrition of Gastropods and Bivalves Relevant to the Mangrove Forests : A Case Study from Central Sumatra, Indonesia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sulfur Nutrition of Gastropods and Bivalves Relevant to the Mangrove Forests : A Case Study from Central Sumatra, Indonesia"}]},"item_type_id":"16","owner":"3","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-18"},"publish_date":"2010-02-18","publish_status":"0","recid":"9173","relation_version_is_last":true,"title":["Sulfur Nutrition of Gastropods and Bivalves Relevant to the Mangrove Forests : A Case Study from Central Sumatra, Indonesia"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:12:26.318194+00:00"}
