Temperature is regarded as an important driver of broad-scale biodiversity patterns. However, less is known of the role of dispersal in shaping broad-scale species and trait distributions, particularly given that species had to disperse out of glacial refugia after the Last Glacial Maximum (LGM). Here, we used a unique dataset describing the distributions of freshwater fauna combined with trait information to evaluate biodiversity relationships to distance to glacial refugia and temperature.

扩散、冰川保护区和温度塑造了欧洲淡水生物多样性的生物地理模式


温度被认为是大范围生物多样性模式的重要驱动因素。然而，人们对扩散在形成大范围物种和性状分布中的作用知之甚少，特别是考虑到在末次盛冰期（LGM）之后物种必须从冰川保护区扩散出来。在这里，我们使用了一个描述淡水动物群分布的独特数据集，并结合特征信息来评估生物多样性与冰川保护区距离和温度的关系。
