（单词翻译）

Why? Because unlike lions, tigers, and other large predators1, the average wolf doesn’t have the bulk or attributes to take down large prey2 with a single blow. Wolves rely more on athleticism3 and endurance to bag elk4. And like most athletes, wolves’ physical abilities decline with age. Once their skills erode5, wolves aren’t much good as hunters. Wolves v Elk So older wolves are good for elk. The study found that the older the average wolf population in an area, the more elk there are still around. When the wolf population skews younger, more elk bite the dust.
