摘要
近年来,许多研究都致力于更好地理解生态学与物种进化成功之间错综复杂的关系。这些探索通常侧重于了解生态因素与物种在不同环境中的进化节奏之间复杂的相互作用。这些研究的核心是查尔斯-达尔文(Charles Darwin)提出的 "适者生存"(survival of the fittest)概念,即进化环境(通常被描述为社会困境)有利于自身利益而非他人利益。为了进一步推进这一研究方向,我们在此建立了一个理论框架,其特点是在进化环境中三个相互关联的特征,即:猎物、捕食者和寄生虫,它们各自采取不同的策略,类似于社会困境,也类似于 "石头-剪子-布 "的情景。我们将这些特征称为战略物种,它们遵循生态进化博弈动力学。我们利用索博尔指数对系统的报酬参数进行了敏感性评估,从而进一步扩展了我们的分析。
The eco-evolutionary dynamics of strategic species
Much research has in recent years been devoted to better our understanding of the intricate relationships between ecology and the evolutionary success of species. These explorations have often focused on understanding the complex interplay among ecological factors and evolutionary rhythms of the species in various environments. Central to these studies is the concept of the survival of the fittest, proposed by Charles Darwin, where evolutionary circumstances, often portrayed as social dilemmas, favour the welfare of self-interested over others. To further advance this line of research, we here develop a theoretical framework that features three interconnected traits in an evolutionary setting, namely: prey, predator and parasite, each adopting distinct strategies akin to a social dilemma and resembling a Rock-Paper-Scissors scenario. These traits, which we term strategic species, adhere to the eco-evolutionary game dynamics. We further extend our analysis by conducting a sensitivity assessment of the system’s payoff parameters using the Sobol indices.
