Through a meta-analysis, Mupepele et al. (BMC Ecol Evol 21:1-193, 2021) assessed the effects of European agroforestry systems on biodiversity, estimated by species richness or species diversity. They showed that the effects of silvoarable and silvopastoral systems depend on the systems they are compared to and the taxa studied. Further, they found that only silvoarable systems increased species richness or diversity, compared to cropland. The authors conclude that agroforestry systems have weak effects on biodiversity and that landscape context or land-use history are probably more important than the practice of agroforestry in itself. However, we draw attention to important shortcomings in this meta-analysis, which downplay the potential of agroforestry for biodiversity conservation in agricultural landscapes. We hope that the meta-analysis by Mupepele et al. (BMC Ecol Evol 21:1-193, 2021), and our comments, will contribute to improving the quality of research on agroforestry systems and biodiversity conservation.
通过一项荟萃分析，穆佩佩勒等人（《BMC生态与进化》21:1 - 193，2021年）评估了欧洲农林业系统对生物多样性的影响，该影响通过物种丰富度或物种多样性来估算。他们表明，混农作业和林牧系统的影响取决于与之比较的系统以及所研究的分类群。此外，他们发现，与农田相比，只有混农作业系统增加了物种丰富度或多样性。作者得出结论，农林业系统对生物多样性的影响较弱，并且景观背景或土地利用历史可能比农林业本身的实践更为重要。然而，我们提请注意这项荟萃分析中的重要缺陷，这些缺陷淡化了农林业在农业景观中保护生物多样性的潜力。我们希望穆佩佩勒等人（《BMC生态与进化》21:1 - 193，2021年）的荟萃分析以及我们的评论将有助于提高关于农林业系统和生物多样性保护的研究质量。
