Keep in mind though that in the lower 48, the area of overlap between wolves and cougars is pretty minuscule. And yeah, doesn't surprise me wolves are dominant. There are plenty of examples of larger predators bossing around smaller ones. Leopards and cheetahs deal with this all the time. Hell, I have heard of grizzlies driving off wolves from kills, so what comes around goes around. I suspect wolves have zero impact on mountain lions from a conservation standpoint, although they might very well change the behavior should wolf expansion continue.
