translate English to French: As these differences were deemed at least as great as those between black-tailed deer (Odocoileus hemionus columbianus) and mule deer (Odocoileus hemionus hemionus), and greater than those between Rocky Mountain bighorn (Ovis canadensis canadensis) and desert bighorn (Ovis canadensis nelsoni), they felt that a subspecific differentiation between wood and plains bison was justified. A subsequent study suggested that the difference in cape colour and tail lengths were not as noticeable as described herein (van Zyll de Jong 1986).
Ces différences morphologiques étant considérées comme au moins aussi importantes que celles qui distinguent le cerf à queue noire (Odocoileus hemionus columbianus) du cerf mulet (Odocoileus hemionus hemionus) et plus grandes que celles qui distinguent le mouflon des montagnes Rocheuses (Ovis canadensis canadensis) du mouflon du désert (Ovis canadensis nelsoni), Geist et Karsten sont d’avis qu’une différenciation subspécifique entre le bison des bois et le bison des prairies est justifiée.
