Abstract
The reproduction and postnatal development of the bushveld gerbil Gerbilliscus (formerly Tatera) leucogaster was studied in the laboratory. Nineteen pairs produced 23 litters. Mean litter size was 3.5 and gestation was 21–22 days. Neonates weighed 3.7 g on average and were altricial. Development was slow, with eyes usually opening 16–18 days after birth, and weaning occurring by about 24 days of age. The earliest age of sexual maturity was 6.6 weeks in females and 9.9 weeks in males. A comparison with other studies of G. leucogaster, and with closely and distantly related similar-sized murid rodents, indicates that reproduction generally varies with geographic location, and that the slow postnatal development of G. leucogaster appears to be phylogenetically constrained.
