A meta-analysis of species richness and restoration outcomes globally.

Species richness is a fundamental component of ecological research including restoration. Managing for enhanced native species richness in restoration is a powerful goal and outcome; nonetheless, local species richness can also be used as a mechanism to decide on the lands to acquire, protect, and restore. Here, a meta-analysis was used to test the hypothesis that local species richness is a viable consideration in predicting varied restoration outcomes as identified by primary researchers in drylands.

物种丰富度（Species richness）是包括生态修复在内的生态学研究的核心构成要素。在生态修复实践中，以提升本土物种丰富度为管理目标，既是极具价值的研究愿景，也是理想的实践成果；尽管如此，本地物种丰富度亦可作为土地收购、保护与生态修复决策的重要依据。本研究采用元分析（meta-analysis）检验了下述假说：在旱地（drylands）生态修复领域中，本地物种丰富度可作为有效考量因素，用于预测原始研究人员所界定的各类修复成效。
