动物正在改变体形,以应对气候变化
At a South African nature preserve where Miya Warrington, a conservation ecologist at the University of Manitoba in Canada, and her colleagues study Cape ground squirrels, the maximum daily temperature has increased by about 2.5℃ in just 18 years. The animals have evolved a quiver of tactics to tolerate the region's sweltering heat, says Warrington.
Sprawling flat on the ground in a pose called splooting helps the animals shed heat from their less furry undersides. The squirrels take shady respites under their bushy tails, which they curl above their heads like tiny parasols. When it's really hot, the fossorial mammals retreat to their burrows to cool off. But Warrington warns that, even with all these options for keeping cool, "still they could be at the limits of their tolerance" due to the climatic shift.
