In response to warming, species are shifting their ranges towards higher elevations. These elevational range shifts have been documented in a variety of taxonomic groups across latitude. However, the rate and direction of species range shifts in response to warming vary, potentially as a consequence of variation in species traits across elevation. Specifically, diurnal and seasonal climates are often more variable at higher elevations, which results in high‐elevation species that have broader thermal physiologies relative to low‐elevation species. High‐elevation species that are thermal generalists might not need to move as far to track their thermal niche as low‐elevation thermal specialists. We investigated whether rates of range shifts varied systematically with increasing elevation across taxa and regions.

山地物种的气候驱动范围变化随海拔变化

为了应对变暖，物种正在将其范围移向更高的高度。这些海拔范围的变化已记录在整个纬度的各种分类组中。但是，物种变迁的速率和方向随变暖而变化，这可能是整个海拔范围内物种特征变化的结果。具体而言，在高海拔地区，昼夜和季节气候通常变化更大，这导致高海拔物种相对于低海拔物种具有更宽的热生理特性。作为热能专家的高海拔物种可能不需要像低海拔热能专家那样走得太远，以追踪其热生态位。我们调查了范围变化率是否随着整个分类单元和地区海拔的升高而系统地变化。
