人类已经改变了世界上大多数自然生态系统的物种分布。对物种分布的分析往往会忽略这些变化，从而可能掩盖自然过程的特征。我们使用当代和估计的自然分布来研究生态学中的经典模式（体重与纬度关系，又名伯格曼规则）的强度，适用于全世界所有哺乳动物物种。我们表明，人类对哺乳动物物种分布的改变导致大大低估了伯格曼规则的强度。我们推测其他大范围的生态模式可能也会受到类似的影响。
Humans have modified species distributions in most of the world's natural ecosystems. Analyses of species distributions tend to ignore these modifications, potentially masking the signatures of natural processes on them. We examine the strength of a classic pattern in ecology-the body mass-latitudinal relationship, aka Bergmann's rule-for all mammal species worldwide using both contemporary and estimated natural distributions. We show that human modifications of mammal species distributions lead to substantially underestimating the strength of the Bergmann's rule. We speculate that other broad-scale ecological patterns might be similarly affected.
