What were the predator populations like during these periods?
Wolf, Lynx, wolverines, etc.
I can tell you about wolves in the upper Noatak River, but it is not believable. I have learned my lesson about telling the truth reference one unbelievable observation. My ass is still burning from the endless flaming on a different forum. And I was on the ground, those who have harvested wolves from an aircraft, claim to have observed equal or higher numbers.
