The question of how wolves survived in North America during the Pleistocene with its large suite of predators, is of interest.
Returning from Eurasia, where they developed into the modern form (although Canis is likely a North American native genus), it might be that C lupus increased following the heavy late-Pleistocene extinction event here. Evidence seems to show they didn’t mix with the thicker, slower Dire Wolf, and are represented in lesser numbers in certain fossil beds.

Back to the present – from the article you can infer that wolves and tigers alternately occupy areas. Thus we can picture the ebb and flow of ecological succession, not only in burned forests, and in ungulate succession, but also in carnivore guild changes.

I do wish though, that we knew more of the real Pleistocene megaherbivore effect on habitats here and Northern Asia- we can only incompletely guess in the face of the fast disappearing African elephants, rhinos, hippos, impervious as adults to predation, what the real world was, is, and would be like, if no uncontrolled chimps toting guns were raving and paving about.
