One of the main factors that determines habitat suitability for sessile and territorial organisms is the presence or absence of another competing individual in that habitat. This type of competition arises in populations occupying patches in a metacommunity. Previous studies have looked at this process using a continuous-time modeling framework, where colonizations and extinctions occur simultaneously. However, different colonization processes may be performed by different species, which may affect the metacommunity dynamics. We address this issue by developing a discrete-time framework that describes these kinds of metacommunity interactions, and we consider different colonization dynamics. To understand potential dynamics, we consider specific functional forms that characterize the colonization and extinction processes of metapopulations competing for space as their limiting factor. We then provide a mathematical analysis of the models generated by this framework, and we compare these results to what is seen in nature and in previous models.

决定栖息地是否适合无柄和领土生物的主要因素之一是该栖息地中是否存在其他竞争性个体。这种竞争发生在占据一个超社区中的斑块的人群中。以前的研究使用连续时间建模框架研究了这个过程，在该过程中，定植和灭绝同时发生。但是，不同的物种可能执行不同的殖民化过程，这可能会影响元社区的动态。我们通过开发一个描述这些元社区相互作用的离散时间框架来解决这个问题，并且我们考虑了不同的殖民动态。要了解潜在的动态，我们将表征争夺空间的超群体的定居和灭绝过程的特定功能形式作为其限制因素。然后，我们对该框架生成的模型进行数学分析，并将这些结果与自然界和先前模型中看到的结果进行比较。
