Temperature is thought to be a key factor influencing global species richness patterns. We investigate the link between temperature and diversification in the butterfly family Pieridae by combining next generation DNA sequences and published molecular data with fine-grained distribution data. We sampled nearly 600 pierid butterfly species to infer the most comprehensive molecular phylogeny of the family and curated a distribution dataset of more than 800,000 occurrences. We found strong evidence that species in environments with more stable daily temperatures or cooler maximum temperatures in the warm seasons have higher speciation rates. Furthermore, speciation and extinction rates decreased in tandem with global temperatures through geological time, resulting in a constant net diversification.
温度被认为是影响全球物种丰富度格局的关键因素。我们通过将下一代DNA序列和已发表的分子数据与精细的分布数据相结合，研究了粉蝶科蝴蝶温度与物种多样化之间的联系。我们对近600种粉蝶进行了采样，以推断该科最全面的分子系统发育，并整理了一个包含超过80万次出现记录的分布数据集。我们发现有力证据表明，在日温度更稳定或温暖季节最高温度较低的环境中的物种具有更高的物种形成率。此外，通过地质时间，物种形成率和灭绝率与全球温度同步下降，导致净多样化保持恒定。
