许多陆地生物的分布目前正在随着气候变化而改变纬度或海拔。使用荟萃分析，我们估计物种分布最近以每十年11.0米的中位速率向高海拔地区转移，并以每十年16.9公里的中位速率向高纬度地区转移。这些速度比以前报告的快大约两到三倍。在显示最高变暖水平的研究中，物种移动的距离最大，平均纬度变化通常足以跟踪温度变化。然而，个别物种的变化率差异很大，这表明每个物种的范围转移取决于多种内部物种特征和外部变化驱动因素。快速的平均变化来自于各个物种的广泛多样的反应。
The distributions of many terrestrial organisms are currently shifting in latitude or elevation in response to changing climate. Using a meta-analysis, we estimated that the distributions of species have recently shifted to higher elevations at a median rate of 11.0 meters per decade, and to higher latitudes at a median rate of 16.9 kilometers per decade. These rates are approximately two and three times faster than previously reported. The distances moved by species are greatest in studies showing the highest levels of warming, with average latitudinal shifts being generally sufficient to track temperature changes. However, individual species vary greatly in their rates of change, suggesting that the range shift of each species depends on multiple internal species traits and external drivers of change. Rapid average shifts derive from a wide diversity of responses by individual species.
