Strange as it sounds, the absence of odor often serves as a powerful stimulis unfamiliar and still unmarked objects or areas prompt vigorous scent marking. This applies to many mammals, including ungulates, such as pronghorn, Antilocapra americana (Muller-Schwarze et al, 1972) rodents, such as house mice, Mus musculus (Hurst, 1987), and carnivores (Kleiman, 1966). For example, pine martens, Maries martes, mark most consistently unmarked objects and do not mark objects that already carry their own odor. It is concluded that marking primarily serves familiarization.

Antibody responses to ovalbumin were significantly lower in five male antelope (Antilocapra americana) fed a diet containing 15 ppm selenium (a mixture of alfalfa and hay naturally high in selenium) for 164 days than in controls fed a similar diet containing only 0.3 ppm selenium, but there was no difference in total globulin concentration between groups (Raisbeck et al. 1996). No clinical signs of selenosis or treatment-associated lesions were observed in these animals.
