Dispersal evolution modifies diverse spatial processes, such as range expansions or biological invasions of single species, but we are currently lacking a realistic vision for metacommunities. Focusing on antagonistic species interactions, we review existing theory of dispersal evolution between natural enemies, and explain how this might be relevant for classic themes in host-parasite evolutionary ecology, namely virulence evolution or local adaptation. Specifically, we highlight the importance of considering the simultaneous (co)evolution of dispersal and interaction traits. Linking such multi-trait evolution with reciprocal demographic and epidemiological feedbacks might change basic predictions about coevolutionary processes and spatial dynamics of interacting species. Future challenges concern the integration of system-specific disease ecology or spatial modifiers, such as spatial network structure or environmental heterogeneity.

扩散进化改变了不同的空间过程，例如单一物种的范围扩张或生物入侵，但我们目前缺乏对元群落的现实愿景。着眼于拮抗物种的相互作用，我们回顾了现有的天敌之间的扩散进化理论，并解释了这如何与宿主-寄生虫进化生态学的经典主题（即毒力进化或局部适应）相关。具体来说，我们强调考虑分散和相互作用特征的同时（共同）进化的重要性。将这种多性状进化与相互的人口统计和流行病学反馈联系起来可能会改变关于相互作用物种的共同进化过程和空间动态的基本预测。未来的挑战涉及系统特定疾病生态学或空间修饰因素的整合，例如空间网络结构或环境异质性。
