岛链上的Biodiversity:中性模型模拟

Biodiversity on island chains: neutral model simulations

Patrick B Warren

摘要:

一个中立的生态模型是在一个岛链上模拟的,在这个岛链中,相邻的岛屿可以交换个体,但只有第一个岛屿能够接收来自一个元共生体的移民。通过几项措施发现,生物多样性沿链条下降,第一个岛屿最高。分类群丰度分布的微妙变化,可以检测到的岛屿链相比,多样性匹配的单一岛屿。这些结果可能适用于人类微生物多样性,但强调了使用静态单站点分类单元丰度分布来区分扩散限制机制的困难。

英文摘要:

A neutral ecology model is simulated on an island chain, in which neighbouring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity. It is found by several measures that biodiversity decreases along the chain, being highest for the first island. Subtle changes in taxon abundance distributions can be detected when islands in the chain are compared to diversity-matched single islands. The results potentially apply to human microbial diversity, but highlight the difficulty of using static single-site taxon abundance distributions to discriminate between dispersal limitation mechanisms.
