气候是全球多样性的强大驱动力，随着人类影响以前所未有的速度推动气温变化，气候将变得越来越重要。在这里，我们调查了不同水生甲壳类动物的多样性和物种形成趋势。与之前的研究不同，我们使用系统发育框架来证明物种形成率与整棵树的全球降温相关。此外，我们发现，随着全球气温的降低，海洋分支继续显示出物种形成率上升的证据，而单一的淡水分支则显示出相反的趋势，物种形成率与全球变暖呈正相关。我们的发现表明，全球变冷和变暖都导致了物种的多样化，栖息地在物种对气候变化的反应中发挥了作用。这些结果对我们理解现存生物群如何应对持续的气候变化具有重要意义，对海洋生态系统的养护规划特别重要。在许多生物群体中，当全球气温变暖时，物种形成率更高。在这里，Davis等人。研究发现，Anomura支系中的海洋甲壳类动物在较冷的时期有较高的物种形成率，而它们的淡水近亲在较温暖的时期有较高的物种形成率。
Climate is a strong driver of global diversity and will become increasingly important as human influences drive temperature changes at unprecedented rates. Here we investigate diversification and speciation trends within a diverse group of aquatic crustaceans, the Anomura. We use a phylogenetic framework to demonstrate that speciation rate is correlated with global cooling across the entire tree, in contrast to previous studies. Additionally, we find that marine clades continue to show evidence of increased speciation rates with cooler global temperatures, while the single freshwater clade shows the opposite trend with speciation rates positively correlated to global warming. Our findings suggest that both global cooling and warming lead to diversification and that habitat plays a role in the responses of species to climate change. These results have important implications for our understanding of how extant biota respond to ongoing climate change and are of particular importance for conservation planning of marine ecosystems. In many groups of organisms, speciation rates are higher when global temperatures are warmer. Here, Davis et al. find that marine crustaceans in the Anomura clade have higher speciation rates during cooler periods, whereas their freshwater relatives have the more typical relationship of higher speciation rates in warmer periods.
