Meta-analysis of ecosystem services associated with oyster restoration on the Eastern and Gulf coasts of the US

We conducted a meta-analysis to systematically quantify the success and uncertainty of oyster reef restoration for a suite of biological, biogeochemical, and physical ecosystem services relative to both degraded and natural reference habitats. We focused on the eastern oyster, Crassostrea virginica. To evaluate whether restored eastern oyster reefs enhance ecosystem services relative to unaltered, degraded habitats and whether restored reefs provide ecosystem services equivalent to reference reefs, we synthesized data and calculated log response ratios for 245 restored-degraded reef pairs and 136 restored-reference reef pairs from 106 publications collected along 3500 km of U.S. Gulf of Mexico and Atlantic coastlines.

本研究开展了一项元分析（meta-analysis），系统量化牡蛎礁修复在多类生物、生物地球化学及物理生态系统服务方面的成效与不确定性，并以退化栖息地与天然参照生境作为对照。研究聚焦于东部牡蛎（eastern oyster，*Crassostrea virginica*）。为评估修复后的东部牡蛎礁是否相较于未受干扰的退化生境提升了生态系统服务，以及修复礁能否提供与参照礁相当的生态系统服务，本研究整合了106篇已发表文献中的数据，针对美国墨西哥湾及大西洋沿岸3500公里海域采集的245对修复-退化礁体、136对修复-参照礁体，计算了对数响应比（log response ratios）。
