The aim of our study was to determine whether the level of pollution in seagrass areas influences seagrass morphology and abundances of associated epifauna. The following hypotheses were tested: 1, the concentration of heavy metals would be significantly higher in seagrass from the polluted location than in seagrass from relatively clean locations; 2, seagrass morphology (shoot density, leaf density, leaf length, and biomass) would be different between polluted and control locations; 3, abundance and diversity of epifauna associated with seagrass would be different between polluted and non-polluted locations. We measured shoot density, leaf density, leaf length and biomass of seagrass, Zostera capricorni, as well as abundance and diversity of associated epifauna. Concentrations of metals (Cd, Cu, Pb, Se, and Zn) in roots and leaves of Z. capricorni were significantly higher in samples from polluted compared to control locations. There were no significant difference in shoot and leaf density, leaf length, and biomass of the seagrass between polluted and control locations. Abundance of gastropods was significantly lower in polluted location than in controls, whereas other epifaunal groups displayed no difference. The results are discussed in view of selecting non-costly bioindicators of heavy metal contamination.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Proceedings of 4th JSPS-VAST Joint Seminar on 'Coastal Marine Science', Hai Phong, Viet Nam, 26-28 October 2009","subitem_description_type":"Other"},{"subitem_description":"Ocean Pollution","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040692","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Atmosphere and Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学大気海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Marine Science Department, Faculty of Marine Science and Fisheries, Hasanuddin University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rappe, Rohani Ambo"}],"nameIdentifiers":[{"nameIdentifier":"93607","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":"2017-06-14"}],"displaytype":"detail","filename":"CMS340130.pdf","filesize":[{"value":"415.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS340130.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40701/files/CMS340130.pdf"},"version_id":"38acdf05-fa51-4b2f-a5c3-0d9147764e7b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"seagrass","subitem_subject_scheme":"Other"},{"subitem_subject":"Zostera capricorni","subitem_subject_scheme":"Other"},{"subitem_subject":"epifauna","subitem_subject_scheme":"Other"},{"subitem_subject":"heavy metal","subitem_subject_scheme":"Other"},{"subitem_subject":"bioindicator","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":"Population and community level indicator in assessment of heavy metal contamination in seagrass ecosystem","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Population and community level indicator in assessment of heavy metal contamination in seagrass ecosystem"}]},"item_type_id":"4","owner":"1","path":["7187","7185"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-25"},"publish_date":"2012-05-25","publish_status":"0","recid":"40701","relation_version_is_last":true,"title":["Population and community level indicator in assessment of heavy metal contamination in seagrass ecosystem"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:19.617256+00:00"}
