摘要

虽然物种丰富度和生态系统稳定性都随着面积的增加而增加，但这些尺度模式之间的联系尚不清楚。对植物和鱼类群落的理论和实证分析表明，生态系统稳定性的空间尺度主要由物种不同步的尺度决定，而物种不同步的尺度又由物种丰富度的尺度驱动。在较湿润的地区，植物物种丰富度和生态系统稳定性随面积的增加速度更快，这意味着随着栖息地的丧失，生物多样性和稳定性的下降可能更大。栖息地丧失后生态系统稳定性的下降可以被推迟，从而产生一种反映物种灭绝债务的稳定债务。通过统一生态学中的两个基本尺度规律，我们的工作强调了持续的生物多样性丧失可能会在空间尺度上破坏生态系统的稳定。

Unifying spatial scaling laws of biodiversity and ecosystem stability

While both species richness and ecosystem stability increase with area, how these scaling patterns are linked remains unclear. Our theoretical and empirical analyses of plant and fish communities show that the spatial scaling of ecosystem stability is determined primarily by the scaling of species asynchrony, which is in turn driven by the scaling of species richness. In wetter regions, plant species richness and ecosystem stability both exhibit faster accumulation with area, implying potentially greater declines in biodiversity and stability following habitat loss. The decline in ecosystem stability after habitat loss can be delayed, creating a stability debt mirroring the extinction debt of species. By unifying two foundational scaling laws in ecology, our work underscores that ongoing biodiversity loss may destabilize ecosystems across spatial scales.

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
