微生物群落的生态进化动力学的预测，影响组成物种的进化克里思和轨迹。虽然社区组成决定了可用的生态位空间，物种排序动态地改变组成，随着时间的推移改变了物种适应的空缺生态位的分布，改变了进化轨迹。竞争相同的生态位可以限制进化潜力，如果人口规模和突变供应减少，但也可以刺激进化分歧，利用空置的生态位，如果字符位移的竞争对手的共同进化的结果。在更复杂的生态情景下，物种可以通过开发复杂的资源来创造新的生态位，使其他物种能够适应这些新形成的生态位。解开这些社区内的自然选择的驱动因素是非常具有挑战性的，因此还不清楚生态进化动力学如何驱动组成类群的进化。我们跟踪了一个焦点物种的代谢进化过程中适应麦草作为一种资源，无论是在单作和混养，其中正在进行的生态进化的社区动态是允许或阻止。物种间的相互作用加速了新陈代谢的进化。生态进化动力学驱动的重点物种的柠檬酸盐底物的使用增加，而更大的开发容易消化的底物生态位创建的其他物种进化，如果正在进行的生态进化动力学被阻止。柠檬酸底物的使用增加与tctE的平行进化有关，tctE编码碳代谢调节剂。物种相互作用和物种排序分别设定了群落间进化分化的克里思和轨迹，在其他等同的生态系统中选择不同的生态功能。生活在一个多物种的社区加速细菌代谢进化物种排序改变了社区之间的代谢进化的轨迹生态进化动力学驱动增加使用难以消化的底物生态位这与tctE的突变有关，tctE编码碳代谢的调节因子Evans et al.表明生活在多物种群落中加速了适应木质纤维素作为资源的焦点细菌的代谢进化。生态进化群落动态阻止焦点物种进化利用其竞争对手的代谢活动，而不是驱动其适应使用难以消化的底物生态位。
The eco-evolutionary dynamics of microbial communities are predicted to affect both the tempo and trajectory of evolution in constituent species. While community composition determines available niche space, species sorting dynamically alters composition, changing over time the distribution of vacant niches to which species adapt, altering evolutionary trajectories. Competition for the same niche can limit evolutionary potential if population size and mutation supply are reduced but, alternatively, could stimulate evolutionary divergence to exploit vacant niches if character displacement results from the coevolution of competitors. Under more complex ecological scenarios, species can create new niches through their exploitation of complex resources, enabling others to adapt to occupy these newly formed niches. Disentangling the drivers of natural selection within such communities is extremely challenging, and it is thus unclear how eco-evolutionary dynamics drive the evolution of constituent taxa. We tracked the metabolic evolution of a focal species during adaptation to wheat straw as a resource both in monoculture and in polycultures wherein on-going eco-evolutionary community dynamics were either permitted or prevented. Species interactions accelerated metabolic evolution. Eco-evolutionary dynamics drove increased use of recalcitrant substrates by the focal species, whereas greater exploitation of readily digested substrate niches created by other species evolved if on-going eco-evolutionary dynamics were prevented. Increased use of recalcitrant substrates was associated with parallel evolution of tctE, encoding a carbon metabolism regulator. Species interactions and species sorting set, respectively, the tempo and trajectory of evolutionary divergence among communities, selecting distinct ecological functions in otherwise equivalent ecosystems. Living in a multispecies community accelerated bacterial metabolic evolution Species sorting altered the trajectory of metabolic evolution between communities Eco-evolutionary dynamics drove increased use of hard-to-digest substrate niches This was linked to mutation of tctE, encoding a regulator of carbon metabolism Evans et al. show that living in a multispecies community accelerates metabolic evolution of a focal bacterium adapting to lignocellulose as a resource. Eco-evolutionary community dynamics prevent the focal species evolving to exploit the metabolic activity of its competitors, instead driving its adaptation to use hard-to-digest substrate niches.
