Abstract

Species frequently engage in both competitive and cooperative interactions, delicately balancing these dynamics to optimize their chances of survival and reproduction. While competition drives individuals to compete for limited resources, cooperation can emerge as a strategic response, mitigating risk and enhancing collective payoff. To bridge theoretical game approaches such as payoff, cooperation, and defections in ecological systems, we propose a two-species predator–prey model inspired by the principles and variations of the prisoner’s dilemma game. We comprehensively address and analytically verify all stable strategic states, exploring the role of payoff parameters both individually and collectively. Additionally, we investigate the effect of free space. Beyond ecological contexts, we present a model of rumor propagation within a social system to establish connections with the prisoner’s dilemma game. In both systems, our primary focus is to discuss strategies and enhance the cooperative factor within the system, given its crucial importance across diverse environments.

两个战略物种的生态进化动态：从捕食者-猎物到无辜传播者的谣言模式。

物种经常同时参与竞争与合作的互动，微妙地平衡这些动态，以优化其生存和繁殖的机会。竞争促使个体争夺有限的资源，而合作则可以作为一种战略对策出现，从而降低风险并提高集体回报。为了连接生态系统中的报酬、合作和叛逃等理论博弈方法，我们受囚徒困境博弈原理和变体的启发，提出了一个双物种捕食者-猎物模型。我们全面探讨并分析验证了所有稳定的战略状态，探讨了报酬参数在个体和集体中的作用。此外，我们还研究了自由空间的影响。除了生态环境，我们还提出了一个社会系统中谣言传播的模型，以建立与囚徒困境博弈的联系。在这两个系统中，我们的主要重点都是讨论策略和增强系统内的合作因素，因为合作因素在不同环境中都至关重要。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
