Purshia tridentata

It is well known that dogs track better in humid air. Rodents find buried seeds better in wet soil. This is important in arid climates. After rains, yellow pine chipmunks, Tamias amoenus, and deer mice, Peromyscus maniculatus found experimentally buried seeds of Jeffrey pine, Pinus jeffreyi, and antelope bitterbrush, Purshia tridentata, better than in diy soil. The recovered number of seeds increased 27- and 15-fold, respectively. In wet soil, seeds take up water rapidly and emanate volatile organic compounds that the rodents exploit. By extension, variations in humidity in arid environments may have profound effects on olfaction-dependent behaviors such as finding food, social interactions, preying, and predator avoidance (Vander Wall 1998).
