Dry season densities of small non-fossorial rodents in five different savanna habitats ranged from 11 to 41 animals ha with corresponding live weights ranging from 310 g to 1557 g ha. Average biomasses of small frodents in two representative savanna types, Burkea and Acacia savanna, were 912 g ha and 816 g ha 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.
在五个不同稀树草原栖息地中，小型非穴居啮齿动物的旱季密度为每公顷11至41只，相应的活体重为每公顷310克至1557克。两种代表性稀树草原类型（伯克亚稀树草原和金合欢稀树草原）中小型啮齿动物的平均生物量分别为每公顷912克和816克。这些生物量与稀树草原中其他重要消费者（鸟类、牛、黑斑羚和蝗虫）的生物量相似，甚至超过了它们。由于异速生长关系，1千克小型稀树草原啮齿动物的能量消耗相当于8千克黑斑羚（Aepyceros melampus）或12.7千克牛。因此，小型啮齿动物对稀树草原的潜在影响比之前认为的要大得多，需要进一步研究。
