A rich body of knowledge links biodiversity to ecosystem functioning (BEF), but it is primarily focused on small scales. We review the current theory and identify six expectations for scale dependence in the BEF relationship: (1) a nonlinear change in the slope of the BEF relationship with spatial scale; (2) a scale-dependent relationship between ecosystem stability and spatial extent; (3) coexistence within and among sites will result in a positive BEF relationship at larger scales; (4) temporal autocorrelation in environmental variability affects species turnover and thus the change in BEF slope with scale; (5) connectivity in metacommunities generates nonlinear BEF and stability relationships by affecting population synchrony at local and regional scales; (6) spatial scaling in food web structure and diversity will generate scale dependence in ecosystem functioning. We suggest directions for synthesis that combine approaches in metaecosystem and metacommunity ecology and integrate cross-scale feedbacks. Tests of this theory may combine remote sensing with a generation of networked experiments that assess effects at multiple scales. We also show how anthropogenic land cover change may alter the scaling of the BEF relationship. New research on the role of scale in BEF will guide policy linking the goals of managing biodiversity and ecosystems.

扩大生物多样性-生态系统功能研究。

丰富的知识体系将生物多样性与生态系统功能(BEF)联系起来,但是它主要集中在小规模领域。我们回顾了当前的理论并确定了BEF关系中尺度依赖的六个期望:(1)BEF关系的斜率与空间尺度的非线性变化;(2)生态系统稳定性与空间范围之间的比例关系;(3)站点内部和站点之间的共存将导致更大范围内的正BEF关系;(4)环境变化的时间自相关影响物种更新,从而影响BEF斜率随尺度的变化;(5)元社区的连通性通过影响局部和区域尺度的人口同步而产生非线性的BEF和稳定性关系;(6)食物网结构和多样性的空间尺度将在生态系统功能中产生尺度依赖性。我们建议综合方向,将元生态系统和元社区生态学中的方法相结合,并整合跨规模的反馈。该理论的测试可能会将遥感与评估多个尺度效果的网络化实验相结合。我们还展示了人为的土地覆盖变化如何可能改变BEF关系的尺度。关于规模在BEF中的作用的新研究将指导将管理生物多样性和生态系统的目标联系起来的政策。该理论的测试可能会将遥感与评估多个尺度效果的网络化实验相结合。我们还展示了人为的土地覆盖变化如何可能改变BEF关系的尺度。关于规模在BEF中的作用的新研究将指导将管理生物多样性和生态系统的目标联系起来的政策。该理论的测试可能会将遥感与评估多个尺度效果的网络化实验相结合。我们还展示了人为的土地覆盖变化如何可能改变BEF关系的尺度。关于规模在BEF中的作用的新研究将指导将管理生物多样性和生态系统的目标联系起来的政策。
