''Rucervus'' is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. They are threatened by habitat loss and hunting, and one species has already gone extinct. They were previously thought to be members of the genus ''Cervus'', but were moved to ''Rucervus'' based mainly on morphological differences. Based on genetic evidence, the Eld's deer should be moved back to ''Cervus'', while the two last species remain in ''Rucervus'' or –less likely– could be moved to ''Axis''.〔Pitraa, Fickela, Meijaard, Groves (2004). ''Evolution and phylogeny of old world deer.'' Molecular Phylogenetics and Evolution 33: 880–895.〕〔Groves (2006). ''The genus Cervus in eastern Eurasia.'' European Journal of Wildlife Research 52: 14–22〕 ==Species== Following the third edition of ''Mammal Species of the World'' from 2005, three species are placed in ''Rucervus'', but the Eld's deer should be split into two species.〔Groves (2006). ''The genus Cervus in eastern Eurasia.'' European Journal of Wildlife Research 52: 14-22.〕 * ''Rucervus duvaucelii'' - barasinga or swamp deer * ''Rucervus eldii'' - Eld's deer or brow-antlered deer * ''Rucervus schomburgki'' - Schomburgk's deer (extinct, 1938) Furthermore, it has also been suggested that the Eld's deer should have its own genus, ''Panolia'', and is closer to Père David's deer.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rucervus」の詳細全文を読む スポンサード リンク
