Urbanization profoundly changes environments, ecosystems and biodiversity. The urban heat island (UHI) effect represents one of the most consistent human‐induced environmental change in urbanized areas. Recently, it was observed that the UHI causes community‐wide shifts towards species with smaller body sizes in urban communities of ectotherms due to increased metabolic costs. We here assembled a large dataset of published data of geographically distant carabid communities collected along urbanization gradients to examine whether we could confirm this consistent change in body size distribution.

随着城市化的推进，只有栖息地专家变得越来越小

城市化深刻改变了环境，生态系统和生物多样性。城市热岛效应（UHI）代表了城市化地区人类最一致的环境变化之一。最近，有人观察到，由于代谢成本增加，UHI导致全市范围内向等温线城市社区中体型较小的物种转移。我们在这里组装了一个大型的已发布数据集，这些数据是沿着城市化梯度收集的地理上遥远的甲族社区的数据，以检查我们是否可以确认体重分布的这种一致变化。
