Gray Wolves as Climate Change Buffers in Yellowstone
Understanding the mechanisms by which climate and predation patterns by top predators co-vary to affect community structure accrues added importance as humans exert growing influence over both climate and regional predator assemblages. In Yellowstone National Park, winter conditions and reintroduced gray wolves (Canis lupus) together determine the availability of winter carrion on which numerou...
متن کاملGray Wolves Help Scavengers Ride Out Climate Change
Average earth temperatures rose 0.6 oC over the last century, according to the latest Intergovernmental Panel on Climate Change.

We hypothesized competition between elk and grizzly bears whereby, in the absence of wolves, increases in elk numbers would increase browsing on berry-producing shrubs and decrease fruit availability to grizzly bears. After wo...
