预测地球表面生物多样性的变化是生态学中的一个基本问题,在本文中,我们将重点讨论研究最广泛的空间生物多样性模式之一:物种-面积关系(SAR)。特区是保育的中央工具,被用来预测全球气候变化后物种的减少,其普遍性在不同的地理区域和生命之树上都是惊人的。在这篇文章中,我们利用量子场论的方法和中性群落生态学的基础,推导出第一个空间上明确的对SAR的中性预测。我们发现,特区有三个阶段,在中等尺度上呈幂函数增长,与数十年有据可查的经验模式一致。我们的模型还为纳入非中性生物变异提供了一个构建块,有可能弥合中性和基于利基的社区组装方法之间的差距。生态通讯(2010)13:87-95
Predicting the variation of biodiversity across the surface of the Earth is a fundamental issue in ecology, and in this article we focus on one of the most widely studied spatial biodiversity patterns: the species–area relationship (SAR). The SAR is a central tool in conservation, being used to predict species loss following global climate change, and is striking in its universality throughout different geographical regions and across the tree of life. In this article we draw upon the methods of quantum field theory and the foundation of neutral community ecology to derive the first spatially explicit neutral prediction for the SAR. We find that the SAR has three phases, with a power law increase at intermediate scales, consistent with decades of documented empirical patterns. Our model also provides a building block for incorporating non-neutral biological variation, with the potential to bridge the gap between neutral and niche-based approaches to community assembly.
