骡鹿

在动物世界，类似的疾病在水貂、骡鹿和麋鹿中也发生过。

In the animal world , similar diseases occur in mink , mule deer , and elk .

科罗拉多西部的山顶平地，过去这里曾经一片空旷，只有骡鹿和艾草鸡在上面自由徜徉，现在布满钻井，条条土路联接其间，从高处望过去，就像是一幅密密麻麻的神经网络图。

Once-empty mesas in western Colorado , where mule deer and sage grouse ranged freely , now look like a neural network from a bird 's-eye view , with well-pads connected by dirt roads scattered across the landscape .
