四十多年来，寄生虫及其宿主进化的理论模型塑造了我们对传染病动态的理解。许多理论模型都假设潜在的生态动态处于平衡或恒定状态，但我们知道，在许多系统中，由于各种内在或外在因素，生态动态会出现波动。在这里，我们讨论了在生态动力学波动的系统中建模进化时所面临的挑战，并总结了为研究此类系统中的宿主-寄生虫进化而开发的主要方法。我们通过将其中一种方法应用于之前在文献中未研究过的宿主进化的两个工作示例，为其中一种方法提供了深入的指南：当由于竞争中的季节性强迫而发生循环时，以及当自由生活的寄生虫的存在导致循环时，并提供了随附的交互式 Python 代码。我们回顾了探索生态动态波动时宿主-寄生虫进化的研究结果，并指出了未来的研究领域。我们始终强调生态和进化动态之间的反馈在推动传染病系统结果方面的重要性。本文是主题“变化世界中的传染病生态学和进化”的一部分。
Theoretical models of the evolution of parasites and their hosts have shaped our understanding of infectious disease dynamics for over 40 years. Many theoretical models assume that the underlying ecological dynamics are at equilibrium or constant, yet we know that in a great many systems there are fluctuations in the ecological dynamics owing to a variety of intrinsic or extrinsic factors. Here, we discuss the challenges presented when modelling evolution in systems with fluctuating ecological dynamics and summarize the main approaches that have been developed to study host–parasite evolution in such systems. We provide an in-depth guide to one of the methods by applying it to two worked examples of host evolution that have not previously been studied in the literature: when cycles occur owing to seasonal forcing in competition, and when the presence of a free-living parasite causes cycles, with accompanying interactive Python code provided. We review the findings of studies that have explored host–parasite evolution when ecological dynamics fluctuate, and point to areas of future research. Throughout we stress the importance of feedbacks between the ecological and evolutionary dynamics in driving the outcomes of infectious disease systems. This article is part of the theme issue ‘Infectious disease ecology and evolution in a changing world’.
