研究了红袋鼠(Macropus Rufus)和黑腹袋鼠(Macropus Robust Us)两种大型食草动物的运动和空间利用模式，以验证袋鼠的运动方式导致栖息地利用与真兽类草食动物不同的假设。通过密集的无线电跟踪和直接观测收集的数据表明，袋鼠在进食时的进展速度比共域绵羊和山羊慢得多。与生活在其他大陆类似环境中的真兽类食草动物的比率相比，情况也是如此。袋鼠的栖息地更小，更离散，它们使用这些栖息地的方式比类似的真兽类食草动物更零散。间接证据支持这样一种假设，即空间使用的这种差异影响了这两个群体的社会行为的演变。
Patterns of movement and space use of two macropodid herbivores, red kangaroos (Macropus rufus) and euros (Macropus robustus), were investigated to test the hypothesis that mode of locomotion of kangaroos leads to differences in habitat use compared with eutherian herbivores. Data gathered from intensive radiotracking and from direct observations indicate that rate of progression while feeding is much slower among kangaroos than that of sympatric sheep and goats. This also is the case when compared with those rates measured for eutherian herbivores living in similar environments on other continents. Kangaroos have smaller, more discrete home ranges, and they use these ranges in a more patchy fashion than analogous eutherian herbivores. Circumstantial evidence supports the hypothesis that such differences in space use affected the evolution of social behavior in the two groups.
