Analyses of fossil mammal faunas from 2945 localities in the United States demonstrate that the geographic ranges of individual species shifted at different times, in different directions, and at different rates in response to late Quaternary environmental fluctuations. The geographic pattern of faunal provinces was similar for the late Pleistocene and late Holocene, but differing environmental gradients resulted in dissimilar species composition for these biogeographic regions. Modern community patterns emerged only in the last few thousand years, and many late Pleistocene communities do not have modern analogs. Faunal heterogeneity was greater in the late Pleistocene.
对来自美国2945个地点的化石哺乳动物群的分析表明，单个物种的地理分布范围在不同时间、不同方向和不同速率上发生了变化，以响应晚第四纪的环境波动。晚更新世和晚全新世动物区系省份的地理格局相似，但不同的环境梯度导致这些生物地理区域的物种组成不同。现代群落格局仅在过去几千年才出现，许多晚更新世群落没有现代的类似物。晚更新世的动物群异质性更大。
