城市和农田侵占了最肥沃、最适宜居住的陆地景观，从根本上改变了全球生态系统。今天，75%的陆地生态系统被人类活动显著改变，景观转换继续加速。人类影响是当前生物多样性危机的主要驱动因素之一，几千年来，人类影响对生态系统功能和物种灭绝速度产生了前所未有的后果。在这里，我们使用化石记录来调查人类影响可能导致的地理范围的变化是否改变了毗邻的美国境内覆盖六个哺乳动物目的46个物种的气候生态位。与工业革命开始之前相比，67%的被研究哺乳动物今天的气候生态位明显不同。在与人类影响的景观重叠的范围内，生态位变化最大。无论是通过强制淘汰/引入，还是通过更间接的手段，大型饮食专家都被从以人类影响地区为特征的气候包络中除名，而较小的、多面手的哺乳动物则得到了便利，在气候空间的这些相同地区定居。重要的是，我们今天发现哺乳动物的气候并不一定代表它们过去的栖息地。在没有缓解的情况下，随着我们进一步进入人类世，我们可以预见到由小型、多面手哺乳动物主导的低地位生物多样性。
Cities and agricultural fields encroach on the most fertile, habitable terrestrial landscapes, fundamentally altering global ecosystems. Today, 75% of terrestrial ecosystems are considerably altered by human activities, and landscape transformation continues to accelerate. Human impacts are one of the major drivers of the current biodiversity crisis, and they have had unprecedented consequences on ecosystem function and rates of species extinctions for thousands of years. Here we use the fossil record to investigate whether changes in geographic range that could result from human impacts have altered the climatic niches of 46 species covering six mammal orders within the contiguous United States. Sixty-seven percent of the studied mammals have significantly different climatic niches today than they did before the onset of the Industrial Revolution. Niches changed the most in the portions of the range that overlap with human-impacted landscapes. Whether by forcible elimination/introduction or more indirect means, large-bodied dietary specialists have been extirpated from climatic envelopes that characterize human-impacted areas, whereas smaller, generalist mammals have been facilitated, colonizing these same areas of the climatic space. Importantly, the climates where we find mammals today do not necessarily represent their past habitats. Without mitigation, as we move further into the Anthropocene, we can anticipate a low standing biodiversity dominated by small, generalist mammals.
