在岛链上模拟中性生态模型，其中相邻岛屿可以交换个体，但只有第一个岛屿能够接收来自元社区的移民。通过多种措施发现α多样性沿着链条减少。当将链中的岛屿与多样性匹配的单个岛屿进行比较时，可以检测到分类单元丰度分布的细微变化。人们发现该岛链具有意想不到的丰富动态。在链中的岛屿之间发现了显着的β多样性相关性，而多样性匹配的单个岛屿之间则不存在这种相关性。这些结果可能适用于人类微生物多样性和生物地理学，并表明个体间和个体内β多样性的测量可以深入了解微生物群落组装机制。
A neutral ecology model is simulated on an island chain, in which neighboring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity. It is found by several measures that alpha-diversity decreases along the chain. Subtle changes in taxon abundance distributions can be detected when islands in the chain are compared to diversity-matched single islands. The island chain is found to have unexpectedly rich dynamics. Significant beta-diversity correlations are found between islands in the chain, which are absent between diversity-matched single islands. The results potentially apply to human microbial biodiversity and biogeography and suggest that measurements of interindividual and intraindividual beta-diversity may give insights into microbial community assembly mechanisms.
