物种间的局部生态位互补性（基于生态位分化的物种划分）预计会对局部生态系统功能产生积极影响。然而，最近的理论预测，更大的地方多样性可能会阻碍当地生态系统功能时，多样性是通过源-汇动态增强。我们建议社区大会作为一种方式，以纳入当地和区域的进程，决定生物多样性及其对生态系统功能的影响。由此，我们提出了一个驼峰形的多样性和生态系统功能之间的关系，在当地尺度上，但线性增加的功能与多样性在区域尺度上，由于区域的互补性。
Local niche complementarity among species (the partitioning of species based upon niche differentiation) is predicted to affect local ecosystem functioning positively. However, recent theory predicts that greater local diversity may hinder local ecosystem functioning when diversity is enhanced through source-sink dynamics. We suggest community assembly as a way to incorporate both the local and regional processes that determine biodiversity and its consequent effects on ecosystem functioning. From this, we propose a hump-shaped relationship between diversity and ecosystem functioning at local scales, but a linear increase of functioning with diversity at regional scales due to regional complementarity.
