本文综述并综合了生态学、进化生物学和种群遗传学等领域的证据,探讨非生物胁迫的存在如何影响生态和进化动力学之间的反馈。为了更好地了解非生物胁迫如何以及在何种条件下影响生态进化动力学,我们用一种概念上的捕食者猎物模型,其中猎物可以迅速发展antipredator防御和压力抗性。我们展示了非生物压力如何通过改变速度和在某些情况下影响生态进化动态这是进化变化的可能性,也是进化与生态学的联系。非生物胁迫是否以及如何影响这一联系取决于对种群规模、突变率、基因流的存在以及相关性状的遗传结构的影响。我们报告了迄今为止在生态进化动力学研究中尚未考虑的生态和种群遗传机制,并提出了未来的研究方向和实验,以了解生态进化动力学的作用在更复杂的生态学和进化论中,这篇文章有一个简单的语言摘要。
We review and synthesize evidence from the fields of ecology, evolutionary biology and population genetics to investigate how the presence of abiotic stress can affect the feedback between ecological and evolutionary dynamics.To obtain a better insight of how, and under what conditions, an abiotic stressor can influence eco‐evolutionary dynamics, we use a conceptual predator–prey model where the prey can rapidly evolve antipredator defences and stress resistance.We show how abiotic stress influences eco‐evolutionary dynamics by changing the pace and in some case the potential for evolutionary change and thus the evolution‐to‐ecology link. Whether and how the abiotic stress influences this link depends on the effect on population sizes, mutation rates, the presence of gene flow and the genetic architecture underlying the traits involved.Overall, we report ecological and population genetic mechanisms that have so far not been considered in studies on eco‐evolutionary dynamics and suggest future research directions and experiments to develop an understanding of the role of eco‐evolutionary dynamics in more complex ecological and evolutionary scenarios.A plain language summary is available for this article.
