使一些血统在全球范围内迅速多样化的过程仍然鲜为人知。尽管早先的研究强调了扩散的重要性，但全球扩张使种群暴露在新的环境中，可能还需要在新的生态位上进行适应和多样化。在这项研究中，我们研究了这些过程对乌鸦和乌鸦(乌鸦属)全球辐射的贡献。结合新的系统发育和全面的表型和气候数据，我们发现乌鸦经历了气候生态位的大规模扩张，同时物种和表型多样化的比率也大幅增加。这些过程的启动与促进扩散和生态位扩张的特征的进化相吻合。我们的发现表明，快速的全球辐射可能被更好地理解为高分散能力与认知等特征协同作用的过程，这些特征有助于在新环境中坚持下去。促进对新环境的适应性反应的特征可能会促进全球辐射。在这里，作者描述了乌鸦的多样化动态，发现它们的全球辐射与表型和气候生态位进化的高速率相吻合。
The processes that allow some lineages to diversify rapidly at a global scale remain poorly understood. Although earlier studies emphasized the importance of dispersal, global expansions expose populations to novel environments and may also require adaptation and diversification across new niches. In this study, we investigated the contributions of these processes to the global radiation of crows and ravens (genus Corvus). Combining a new phylogeny with comprehensive phenotypic and climatic data, we show that Corvus experienced a massive expansion of the climatic niche that was coupled with a substantial increase in the rates of species and phenotypic diversification. The initiation of these processes coincided with the evolution of traits that promoted dispersal and niche expansion. Our findings suggest that rapid global radiations may be better understood as processes in which high dispersal abilities synergise with traits that, like cognition, facilitate persistence in new environments. Traits that facilitate adaptive responses to novel environments may facilitate global radiations. Here, the authors describe diversification dynamics of crows, finding that their global radiation coincides with high rates of phenotypic and climatic niche evolution.
