There are disagreements on the taxonomy among researchers; for example, Corbet and Hill (1992) recognized 11 species of Eothenomys, Whereas Musser and Carleton (1993) categorized only nine species of Eothenomys along with two species of Phaulomys. Because a diagnostic characteristic distinguishing Clethrionomys from Eothenomys -- whether molar roots present in aged specimens -- changes with age, the difference appears to be gradual rather than clear-cut. Morphological differences in the upper molar patterns appear on a continuum from species to species. Furthemore, the simple form of the third upper molar pattern appears in aged specimens of E. andersoni and E. shanseius as well as C. glareolus and C. rufocanus -- of which the latter two species have roots -- whereas the pattern does not change thoughout growth in E. regulus, E. inez, E. eva, E. chinensis, E. wardi, E. custos and E. proditor as well as Microtus pennsylvanicus, which has no root. E. smithii shows and intermediate condition, in which a few simple form exist in aged specimens. Considering the variation in these species, study of redefinition of the genus Eothenomys is needed.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"特集「哺乳類の類縁をさぐる」","subitem_heading_language":"ja"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本哺乳類学会","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":"10017519708","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/10.11238/mammalianscience.38.129","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":"AN00231656","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-437X","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"1696"}]},"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":"AN00231656_38_1_129.pdf","filesize":[{"value":"723.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00231656_38_1_129","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/500/files/AN00231656_38_1_129.pdf"},"version_id":"36bd21b9-7b45-46e6-84cc-afdf18b73e75"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"分類と形態からみたビロードネズミ属とヤチネズミ属","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"分類と形態からみたビロードネズミ属とヤチネズミ属","subitem_title_language":"ja"},{"subitem_title":"The taxonomic history of the genus Eothenomys based on morphological characteristics","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":"500","relation_version_is_last":true,"title":["分類と形態からみたビロードネズミ属とヤチネズミ属"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-10-17T08:06:56.003270+00:00"}
