Ursinae is a subfamily of Ursidae (bears) named by Swainson (1835) though probably named before Hunt 1998. It was assigned to Ursidae by Bjork (1970), Hunt (1998) and Jin et al. (2007). ==Classification== Ursidae (family) *Ursinae (subfamily) * * *''Melursus'' (genus) * * * *''Melursus ursinus'' (sloth bear) * * * * *''Melursus ursinus inornatus'' (Sri Lankan sloth bear) * * * * *''Melursus ursinus ursinus'' (Indian sloth bear) * * *''Helarctos'' (genus) * * * *''Helarctos malayanus'' (sun bear) * * * * *''Helarctos malayanus euryspilus'' (Borneo sun bear) * *Ursini (tribe) * * *''Ursus'' (genus) * * * *''Ursus abstrusus''† (primitive black bear) * * * *''Ursus americanus'' (American black bear) * * * * *''Ursus americanus cinnamomum'' (cinnamon bear) * * * * *''Ursus americanus floridanus'' (Florida black bear) * * * * *''Ursus americanus luteolus'' (Louisiana black bear) * * * * *''Ursus americanus kermodei'' (Kermode bear) * * * *''Ursus arctos'' (brown bear) * * * * *''Ursus arctos syriacus'' (Syrian brown bear) * * * * *''Ursus arctos horribilis'' (grizzly bear) * * * * *''Ursus arctos middendorffi'' (Kodiak bear) * * * * *''Ursus arctos isabellinus'' (Himalayan brown bear or Himalayan red bear) * * * * *''Ursus arctos piscator''†?

The Asiatic black bear and the polar bear used to be placed in their own genera, ''Selenarctos'' and ''Thalarctos''; these are now placed at subgenus rank. A number of hybrids have been bred between American black, brown, and polar bears (see Ursid hybrids). 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「Ursinae」の詳細全文を読む スポンサード リンク
