Comparative ecological and behavioral adaptations of Ovibos moschatus and Rangifer tarandus
Caribou/reindeer and muskoxen are the only two ungulate species that have successfully occupied arctic tundra habitats. Although confronted with similar environmental constraints, their morphological dissimilarities have enabled them to develop unique behavioral and ecological adaptations that under...
