In 1995, ecologists started to reintroduce the wolf into Yellowstone Park, where the wolf had been eliminated intentionally half a century earlier. Rangers expected a rise in the number of wolf would place limits on the elk population and on the populations of many mid-size mammals. One unexpected consequence was a dramatic rise in the population of foxes, which in turn helped to control many rodent populations.
Question List: 1
Which of the following, if true, most helps explain the dramatic rise in the fox population?
- A Foxes are too small to hunt elk
- B Foxes choose very different breeding area than do wolves
- C The main predators of the fox were coyotes, on which the wolf preys.
- D Elk hunting is more popular, and more widely marketable, than is fox hunting
- E In the agricultural counties surrounding Yellowstone, there are significantly lower wolf and fox populations.
