An experiment was conducted to determine the microhabitat preferences of two heteromyid rodents, Dipodomys ordi and Perognathus flavus. This experiment used marked seeds and the atomic absorption spectrophotometer in order to study the environment as a mosiac of microhabitats. The results of our analysis indicate that these two heteromyids are microhabitat selectors. The preferences of the rodents are D. ordi: grass habitat 0.0%, near grass habitat 22.5%, open habitat 77.4% and P. flavus: grass habitat 46.2%, near grass habitat 32.2%, open habitat 21.4%. The overlap between the two species is only 0.43.
进行了一项实验，以确定两种异鼠科啮齿动物（奥氏更格卢鼠和金黄更格卢鼠）对微生境的偏好。该实验使用了有标记的种子和原子吸收分光光度计，以便将环境作为微生境的镶嵌体来研究。我们的分析结果表明，这两种异鼠科动物是微生境选择者。啮齿动物的偏好为：奥氏更格卢鼠：草地生境0.0%，近草地生境22.5%，开阔生境77.4%；金黄更格卢鼠：草地生境46.2%，近草地生境32.2%，开阔生境21.4%。这两个物种之间的重叠率仅为0.43。
