尽管自20世纪80年代以来，尺度和生物多样性的概念在科学文献中得到了越来越多的关注，但对这两个概念进行联合研究的速度要慢得多。我们发现尺度因素已被明确纳入与生物多样性相关的六大调查领域：(1)生态系统内部和生态系统之间的异质性；(2)干扰生态学；(3)保护和恢复；(4)入侵生物学；(5)时间尺度对理解过程的重要性；(6)物种对环境异质性的响应。除了将本专题的论文置于对这六个主题的扩展文献的简要总结的背景下外，我们还概述了将尺度考虑纳入生物多样性研究的有用工具。这些工具包括层次和结构方程建模、克里格法、变宽缓冲、k折交叉验证和级联图等。最后，我们讨论了一些仍然存在的主要挑战和研究前沿，并对未来进行了展望。
Although the concepts of scale and biological diversity independently have received rapidly increasing attention in the scientific literature since the 1980s, the rate at which the two concepts have been investigated jointly has grown much more slowly. We find that scale considerations have been incorporated explicitly into six broad areas of investigation related to biological diversity: (1) heterogeneity within and among ecosystems, (2) disturbance ecology, (3) conservation and restoration, (4) invasion biology, (5) importance of temporal scale for understanding processes, and (6) species responses to environmental heterogeneity. In addition to placing the papers of this Special Feature within the context of brief summaries of the expanding literature on these six topics, we provide an overview of tools useful for integrating scale considerations into studies of biological diversity. Such tools include hierarchical and structural-equation modelling, kriging, variable-width buffers, k-fold cross-validation, and cascading graph diagrams, among others. Finally, we address some of the major challenges and research frontiers that remain, and conclude with a look to the future.
