Answer to Question 1

Pronghorn would have a competitive advantage over domestic sheep on cold desert ranges in winter. When grasses and forbs are covered with snow, pronghorn can readily use shrubs such as big sagebrush, high in volatile oils. These plants tend to be toxic to sheep if consumed in high amounts. Pronghorn can apparently cope with volatile oils in big sagebrush through selectivity, fine chewing of food, and possibly by detoxification in the digestive tract or liver.
