Each specimen was classified into one of five age groups (I-V) determined by the wear of the three upper molars. The spiny rat of Okinawa has on average within age groups III and IV a statistically longer and wider skull and a longer molar row than that of Amami Oshima. However, neither the posterior nor the central parts of the skull length and width differ between the two islands. Against the same size of head and body length (H&BL) or incisor - the third upper molar length (I-M3), the spiny rat of Okinawa has longer I-M3 or narrower zygomatic arches than the spiny rat of Amami Oshima. The Okinawan spiny rat has a wider first upper molar (wM1≥1.9 mm), whereas that of Amami Oshima is wM1≤1.8 mm. The Okinawan spiny rat has the palatine foramen of the skull situated more posteriorly than that of Amami Oshima. These findings indicate conclusively that the spiny rat populations on the two islands of Amami Oshima and Okinawa have distinctly different morphological characteristics, in addition to having different karyotypes, and as such they should be regarded as distinct species. The spiny rat of Amami Oshima should be named as Tokudaia osimensis (Abe, 1933) while that of Okinawa should be known as Tokudaia muenninki (Johnson, 1946).","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Mammalogical Society of Japan","subitem_publisher_language":"en"},{"subitem_publisher":"日本哺乳動物学会","subitem_publisher_language":"ja"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10013013579","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3106/mammalstudy.26.17","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2001 The Mammalogical Society of Japan","subitem_rights_language":"en"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11185060","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1343-4152","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"1662"}]},"item_10001_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"金子, 之史","creatorNameLang":"ja"},{"creatorName":"カネコ, ユキブミ","creatorNameLang":"ja-Kana"},{"creatorName":"Kaneko, Yukibumi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-25"}],"displaytype":"detail","filename":"AA11185060_26_1_17.pdf","filesize":[{"value":"673.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11185060_26_1_17","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/491/files/AA11185060_26_1_17.pdf"},"version_id":"4be4db1d-b69b-4ec9-857e-5c1902e20264"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tokudaia osimensis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tokudaia muenninki","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Okinawa","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Amami Oshima","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":"Morphological discrimination of the Ryukyu spiny rat (genus Tokudaia) between the islands of Okinawa and Amami Oshima, in the Ryukyu Islands, southern Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Morphological discrimination of the Ryukyu spiny rat (genus Tokudaia) between the islands of Okinawa and Amami Oshima, in the Ryukyu Islands, southern Japan","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"11","path":["2"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-27"},"publish_date":"2012-03-27","publish_status":"0","recid":"491","relation_version_is_last":true,"title":["Morphological discrimination of the Ryukyu spiny rat (genus Tokudaia) between the islands of Okinawa and Amami Oshima, in the Ryukyu Islands, southern Japan"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-10-17T08:06:25.328442+00:00"}
