The larger specimen, with six to seven whorls, had visible ribs on its most outer whorl. The shell thickness of L. helicina antarctica forma antarctica was very thin, approximately 5–7 μm, on an individual with a shell diameter of 1.4 mm. Shell microstructure, as examined by SEM, was composed mostly of a crossed-lamellar structure. Shell thickness of the dominant benthic bivalve Laternula elliptica, was approximately 99–132 μm on an individual of shell length 19 mm. It was composed of two calcareous layers, including a thick outer homogeneous or granular layer and a thin nacreous inner layer. The characteristics of shell structure are discussed with reference to previous results, and in terms of adaptation to Antarctic waters.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"南極海に生息する浮遊性巻貝 Limacina helicina antarctica forma antarctica の貝殻外表面は滑らかであるが、螺層が6-7巻きの大型個体では、もっとも外側の巻きに明瞭な肋がみられた。本種の殻の厚さは非常に薄く、殻径が1.4 mm の個体で約5-7 μm だった。走査型電子顕微鏡で観察した結果、貝殻の大部分は交差板構造で構成されていた。優占する底生性のオキナガイ科の二枚貝 Laternula elliptica の殻も薄く、殻長19 mm の個体で約99-132 μm だった。本種の石灰化層は２層あり、外側は厚く、均一構造（粒状構造）で内側は薄く真珠構造であった。このような貝殻構造の特徴について、これまでの結果や南極海への適応という観点から考察した。\n","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110007702220","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2010.05.006"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.05.006","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"W., Sato-Okoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"K., Okoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"H., Sasaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"F., Akiha"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"W., Sato-Okoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"K., Okoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"H., Sasaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"F., Akiha","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Shell structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Pteropoda","subitem_subject_scheme":"Other"},{"subitem_subject":"Limacina helicina antarctica forma antarctica","subitem_subject_scheme":"Other"},{"subitem_subject":"Laternula elliptica","subitem_subject_scheme":"Other"},{"subitem_subject":"Shell structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pteropoda","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Limacina helicina antarctica forma antarctica","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Laternula elliptica","subitem_subject_language":"en","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":"Shell structure characteristics of pelagic and benthic molluscs from Antarctic waters","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shell structure characteristics of pelagic and benthic molluscs from Antarctic waters"},{"subitem_title":"Shell structure characteristics of pelagic and benthic molluscs from Antarctic waters","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1355"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10171","relation_version_is_last":true,"title":["Shell structure characteristics of pelagic and benthic molluscs from Antarctic waters"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:21.480486+00:00"}
