伯格曼法则（Bergmann's rule）是一个被广泛接受的地理学法则，指出一个物种内的个体在温暖的环境中会变小。虽然有许多单物种的研究和综合评论记录了这种模式，但尚未使用数据密集型方法来确定这种模式的普遍性。我们评估了952种鸟类和哺乳动物物种的温度和个体质量之间的种内关系的强度和方向。对于87%的物种，温度解释了不到10%的质量变化，对于79%的物种，相关性在统计学上不显著。这些结果表明，伯格曼规则是不普遍的，温度不是一个主要的驱动程序的质量的地形变化。进一步了解尺寸变化将需要整合影响尺寸的多个过程。缺乏主导的温度强迫削弱了假设的理由，全球变暖可能会导致广泛的身体大小减少。
Bergmann’s rule is a widely-accepted biogeographic rule stating that individuals within a species are smaller in warmer environments. While there are many single-species studies and integrative reviews documenting this pattern, a data-intensive approach has not been used yet to determine the generality of this pattern. We assessed the strength and direction of the intraspecific relationship between temperature and individual mass for 952 bird and mammal species. For eighty-seven percent of species, temperature explained less than 10% of variation in mass, and for 79% of species the correlation was not statistically significant. These results suggest that Bergmann’s rule is not general and temperature is not a dominant driver of biogeographic variation in mass. Further understanding of size variation will require integrating multiple processes that influence size. The lack of dominant temperature forcing weakens the justification for the hypothesis that global warming could result in widespread decreases in body size.
