Larger species of seed-eating desert rodents were excluded from experimental plots while smaller, potentially competing species were allowed to enter. Density of small granivores on these plots increased to nearly 3.5 times that on control plots but only after 8 months. These results indicate that interspecific competition affects the abundance of desert rodents; they also support indirect evidence that competition for seeds influences the organization of desert rodent communities.
在实验区域中排除了较大的食籽沙漠啮齿动物，而允许较小的、可能具有竞争关系的物种进入。这些区域中小食籽动物的密度增加到对照区域的近 3.5 倍，但这一情况仅在 8 个月后才出现。这些结果表明种间竞争会影响沙漠啮齿动物的丰度；它们还支持了关于种间竞争影响沙漠啮齿动物群落结构的间接证据。
