Although there is little information available specifically on the biology of the lesser short-tailed gerbil, it is likely to be similar to closely related species. Gerbillus species live in simple burrows, where the air is generally more humid than outside, which helps gerbils conserve moisture in arid habitats (4). Other adaptations that allow these gerbils to live in areas where water is scarce include producing very concentrated urine and dry faeces, in order to conserve water, and being active only at night (3). This not only allows gerbils to avoid the hot sun, but also means they feed at night when dew accumulates on the food, thereby increasing their water intake (4).
Gerbils typically have a diet of grass seeds, stems and roots, fallen fruits and nuts, and some insects (3) (4). There have been reports of some gerbils being attracted to grass fires, probably to feed on insects fleeing the area (4). Small carnivores, owls and snakes are all possible predators of gerbils (4).
Gerbils are born blind and hairless after a gestation period of around three weeks (4). The mother creates a nest in the burrow, lining it with fur from her belly (4). The young begin to grow fur a week after birth, and after two or three weeks the eyes open and teeth break through (4).
