Average biomasses of small rodents in two representative savanna types, Burkea and Acacia savanna, were 912 g ha -1 and 816 g ha -1 respectively. These biomasses were similar to or even exceeded biomasses of other important consumers (birds, cattle, impala, and grasshoppers) in the savanna. Due to allometric relationships 1 kg of small savanna rodents is equivalent in energy consumption to 8 kg of impala (Aepyceros melampus) or 12.7 kg of cattle. The potential effect of small rodents on the savanna is therefore much larger than previously thought and needs further investigation.

Individual home range sizes in males increased and in females decreased with increasing body weight. Relating these changes to changed energetic requirements failed. In these species behavioral aspects seem to be a more important determinant of home range size than body weight.
