Deer mice living at altitude must deal with low P_{O2} and low temperatures. Which of the following strategies (which the mice actually use) makes the most sense, given our lecture?
a) The mice might preferentially consume foods high in lipids over foods high in carbohydrates.
b) The mice might shift their diet more towards lipids when the temperature drops.
c) The mice might have a lower resting alveolar ventilation rate than lowland mice.
d) The mice might use lipid fuels for baseline metabolic activities like shivering, sparing carbohydrate fuels for more intense exercise such as fleeing from predators.
