There have been conflicting reports in the last decade on the extent to which coexisting heteromyid rodent species select different sizes or species of seeds. Here I report results of laboratory choice experiments that show heteromyids of different size and genus to have similar preferences for wheat particles of various sizes, and for commercially available seed species that differ considerably in nutritional and morphological characteristics. I also discuss the significance of this finding for mechanisms of coexistence in natural communities.
在过去十年里，关于共存的更格卢鼠科啮齿动物物种选择不同大小或种类种子的程度，一直存在相互矛盾的报道。在此，我报告实验室选择实验的结果，这些结果表明，不同大小和属的更格卢鼠科动物对各种大小的小麦颗粒，以及对营养和形态特征差异很大的市售种子种类，具有相似的偏好。我还讨论了这一发现对于自然群落中共存机制的意义。
