Japanese sand lances are distributed widely in Japanese coastal waters and possess vivid spots on the both sides of their head, which reflect environmental light and can be visually observed. However, the population in Otsuchi Bay, Iwate completely lacks these spots, which is mutual in the sympatric species A. japonicus and A. heian. This difference in the local population in the Otsuchi Bay relative to those in other localities has been likely overlooked because the spots quickly disappear after the fish dies; therefore, they are not recognizable in preserved specimens. Furthermore, the population in Sendai Bay, Miyagi consists of individuals with these spots present (75%) and absent (25%), suggesting an immigration of the latter from the northern Sanriku Coast. Microscopic observation revealed that the spots are iridophore-like cells because of their oval shape and the absence of pigments and are probably connected to the nervous system. The present study should encourage future research to clarify the taxonomy and population structure of Japanese sand lances, whose stock has been decreasing and for which a management plan is urgently needed.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Short Note","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00079482","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_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"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_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":"School of Marine Biosciences, Kitasato University"},{"subitem_text_value":"International Coastal Research Center, Atmosphere and Ocean Research Institute, the University of Tokyo"},{"subitem_text_value":"National Research Institute of Fisheries and Environment of Inland Sea, Japan Fisheries Research and Education Agency"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Amiya, Noriko"}],"nameIdentifiers":[{"nameIdentifier":"161640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Tatsuki"}],"nameIdentifiers":[{"nameIdentifier":"161641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ida, Hitoshi"}],"nameIdentifiers":[{"nameIdentifier":"161642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoyama, Jun"}],"nameIdentifiers":[{"nameIdentifier":"161643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoneda, Michio"}],"nameIdentifiers":[{"nameIdentifier":"161644","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":"2020-08-31"}],"displaytype":"detail","filename":"CMS430103.pdf","filesize":[{"value":"4.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS430103.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54366/files/CMS430103.pdf"},"version_id":"13ed3b78-126a-4926-bb27-111a80129865"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ammodytes","subitem_subject_scheme":"Other"},{"subitem_subject":"iridophore","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese sand lance","subitem_subject_scheme":"Other"},{"subitem_subject":"morphology","subitem_subject_scheme":"Other"},{"subitem_subject":"Otsuchi Bay","subitem_subject_scheme":"Other"},{"subitem_subject":"Sanriku Coast","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":"Unique morphological characteristics of Japanese sand lances, genus Ammodytes, possibly endemic along the northern Sanriku Coast","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Unique morphological characteristics of Japanese sand lances, genus Ammodytes, possibly endemic along the northern Sanriku Coast"}]},"item_type_id":"4","owner":"1","path":["8452","8450"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-31"},"publish_date":"2020-08-31","publish_status":"0","recid":"54366","relation_version_is_last":true,"title":["Unique morphological characteristics of Japanese sand lances, genus Ammodytes, possibly endemic along the northern Sanriku Coast"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:31:58.167181+00:00"}
