在这里，我们使用现实的计算机模拟细菌来研究专业化的演变，这些细菌在动态的液体中分泌两种公共物品。通过这一第一原理方法，我们发现，物理因素，如扩散、流动模式和衰减率，在控制社区结构演变方面与健康经济学一样有影响，在某种程度上，当考虑到机械因素时，(A)尽管专门化的入侵适合性，多面手社区可以抵制成为专家；(B)多面手和专家都可以抵制作弊者，尽管顺风车的入侵；以及(C)尽管竞争排斥的相反力量，多种社区结构可以共存。我们的结果强调了空间分类和物理力量在生态位划分和多样化群落结构演变中的作用。
Here, we study the evolution of specialization using realistic computer simulations of bacteria that secrete two public goods in a dynamic fluid. Through this first‐principles approach, we find physical factors such as diffusion, flow patterns and decay rates are as influential as fitness economics in governing the evolution of community structure, to the extent that when mechanical factors are taken into account, (a) generalist communities can resist becoming specialists despite the invasion fitness of specialization; (b) generalist and specialists can both resist cheaters despite the invasion fitness of free‐riding; and (c) multiple community structures can coexist despite the opposing force of competitive exclusion. Our results emphasize the role of spatial assortment and physical forces on niche partitioning and the evolution of diverse community structures.
