Several frameworks have been applied to organization of communities under natural selection. Of these, the concept of Evolutionarily Stable Strategies (ESS) provides a powerful framework evaluating the consequences of density-dependent and frequency-dependent selection within and among species. Here, the ESS concept will be applied to the investigation of three evolutionary scenarios relevant to natural selection's influence on properties of communities: 1) predator-prey coevolution, 2) evolution of habitat and diet selection, and 3) evolution in spatially heterogeneous environments. The predator-prey model breaks the traditional dichotomy between the coevolution of competitors and the coevolution of predator-prey by permitting coevolution among species within and between trophic levels. Habitat selection as an evolutionary game considers the prevalent role of habitat and diet partitioning in promoting the evolution and coexistence of competitors. In all three scenarios, the emphasis is on determining evolutionary and ecological properties of communities that promote or inhibit species diversity.

一些框架已被应用于自然选择下的社区组织。其中，进化稳定策略(ESS)的概念提供了一个强大的框架来评估依赖密度和依赖频率的物种内和物种间选择的后果。在这里，ESS的概念将被应用于与自然选择对群落性质的影响相关的三个进化场景的研究：1)捕食者-被捕食者的共同进化，2)生境和食物选择的进化，以及3)空间异质环境的进化。捕食者-被捕食者模型打破了竞争者的共同进化和捕食者-被捕食者-猎物的共同进化之间的传统二分法，允许在营养水平内和之间的物种之间的共同进化。栖息地选择作为一种进化博弈，考虑了栖息地和食物划分在促进竞争对手进化和共存方面的普遍作用。在所有三种情况下，重点都是确定促进或抑制物种多样性的群落的进化和生态特性。
