The geography of metacommunities - Code and Data

In this study, we used simulation models to demonstrate that a conceptual framework centered on the dependency of species pool characteristics on landscape attributes is valuable for understanding the geography of metacommunity assembly, i.e., understanding variation in the relative importance of mechanisms that assemble different metacommunities distributed along broad-scale ecological gradients or across biogeographic regions. We used empirical data on moth metacommunities in a tropical (data from Maicher et al. 2019) and temperate mountain (Miller and Jones 2005) to provide empirical validation of some of the predictions derived from our simulation models.<br>

本研究通过模拟模型证实，以“物种库（species pool）特征随景观属性（landscape attributes）变化的依赖关系”为核心的概念框架，对解析集合群落（metacommunity）组装的地理格局具有重要意义；具体而言，该框架可阐明沿大尺度生态梯度分布或跨生物地理区域分布的不同集合群落，其组装机制的相对重要性的变化规律。本研究采用热带地区蛾类集合群落（数据源自Maicher等2019年研究）与温带山地蛾类集合群落（数据源自Miller与Jones 2005年研究）的实证数据，对本研究模拟模型推导得到的部分预测结果开展实证验证。
