The management of harmful species, including invasive species, pests, parasites, and diseases, is a major, global challenge. Harmful species cause severe damage to ecosystems, biodiversity, agriculture, and human health. The control of harmful species is challenging and often requires cooperation among multiple agents, such as land‐owners, agencies, and countries. Agents may have incentives to contribute less, leaving more work for other agents, which can result in inefficient treatment. Here we present a dynamic game theory model and we show that slow treatment may promote a stable solution (Markovian Nash equilibrium) where all agents cooperate to remove the harmful species. The efficiency of this solution depends critically on the life history of the harmful species that determines the speed of optimal treatment. Furthermore, this cooperative equilibrium may coexist with other Nash equilibria, including one dictating no treatment of the harmful species, which implies that coordination among agents is critical for successful control.

慢速处理可促进多种药物对有害物种的控制

有害物种的管理,包括入侵物种,害虫,寄生虫和疾病,是一项重大的全球性挑战。有害物种严重破坏了生态系统,生物多样性,农业和人类健康。有害物种的控制具有挑战性,通常需要土地所有者,机构和国家等多个部门之间的合作。特工可能有动力减少捐款,而其他特工会更多工作,这可能会导致治疗效率低下。在这里,我们介绍了一个动态博弈论模型,我们证明了慢速处理可以促进稳定的溶液(Markovian Nash平衡),在该溶液中所有作用剂共同清除有害物质。该解决方案的效率主要取决于有害物种的生命历史,从而决定了最佳治疗的速度。此外,
