I think that climate changes can promote at the first stage little changes in the forage plants used in the diet of the reindeer/caribou, and in the advantage stages the species must be forced to modified the space use, will need migrate to other areas never used... I don't know. I hope that field biologists in north hemisphere has thinking about that, and call atention for that, like you.
