The sandbathing and grooming behaviour of ten kangaroo rats (Dipodomys merriami) were recorded on sand and woodchip substrates after periods of 0, 1, 5 and 10 days without sand. Sandbathing is restricted to the sandy substrate. Grooming occurs on both, but with a higher frequency on sand. Increases in both grooming and sandbathing occur with increasing sand deprivation, but the temporal patterning does not change. D. merriami tends to alternate sandbathing components in contrast to other Dipodomys species. Lipid on the pelage increases noticeably with sand deprivation and decreases during a sandbathing bout; sand appears to be removed from the pelage by shaking and grooming. These findings suggest a three-process system for care of the body surface.
在分别经历0天、1天、5天和10天无沙环境后，记录了10只更格卢鼠（Merriam袋鼠更格卢鼠）在沙地和木屑基质上的沙浴和梳理行为。沙浴仅限于沙地基质。梳理行为在两种基质上都有发生，但在沙地上的频率更高。随着缺沙时间的增加，梳理和沙浴行为都有所增加，但时间模式没有改变。与其他更格卢鼠物种相比，Merriam袋鼠更格卢鼠倾向于交替进行沙浴动作。随着缺沙，体表的脂质显著增加，而在一次沙浴过程中减少；沙子似乎通过抖动和梳理从体表去除。这些发现表明存在一个用于体表护理的三过程系统。
