Spatial patterns are ubiquitous across different scales of organization in ecological systems. Animal coat pattern, spatial organization of insect colonies and vegetation in arid areas are prominent examples from such diverse ecologies. Typically, pattern formation has been described by reaction-diffusion equations, which consider individuals dispersing between subpopulations of a global pool. This framework applied to public goods game nicely showed the endurance of populations via diffusion and generation of spatial patterns. However, how the spatial characteristics, such as diffusion, are related to the eco-evolutionary process as well as the nature of the feedback from evolution to ecology and vice versa, has been so far neglected. We present a thorough analysis of the ecologically driven evolutionary dynamics in a spatially extended version of ecological public goods games. Furthermore, we show how these evolutionary dynamics feed back into shaping the ecology, thus together determining the fate of the system.
空间格局在生态系统中不同组织尺度上普遍存在。动物皮毛图案、昆虫群落的空间组织以及干旱地区的植被,都是来自如此多样生态环境的突出例子。通常,图案形成是由反应扩散方程描述的,该方程考虑个体在全球种群库的亚种群之间扩散。这个应用于公共物品博弈的框架很好地展示了种群通过扩散和空间格局的产生而具有的持久性。然而,到目前为止,诸如扩散等空间特征如何与生态进化过程相关,以及从进化到生态以及反之亦然的反馈性质,一直被忽视。我们对生态公共物品博弈的空间扩展版本中的生态驱动进化动力学进行了全面分析。此外,我们展示了这些进化动力学如何反馈到塑造生态中,从而共同决定系统的命运。
