We found that  plant communities of biodiversity experiments cover almost all of the  multivariate variation of the real-world communities, while also  containing community types that are not currently observed in the real  world. Moreover, they have greater variance in their compositional  features than their real-world counterparts. We then re-analysed a  subset of experimental data that included only ecologically realistic  communities (that is, those comparable to real-world communities). For  10 out of 12 biodiversity\u2013ecosystem functioning relationships,  biodiversity effects did not differ significantly between the full  dataset of biodiversity experiments and the ecologically realistic  subset of experimental communities. Although we do not provide direct  evidence for strong or consistent biodiversity\u2013ecosystem functioning  relationships in real-world communities, our results demonstrate that  the results of biodiversity experiments are largely insensitive to the  exclusion of unrealistic communities and that the conclusions drawn from  biodiversity experiments are generally robust. <\/p>\n\n\n\n<p>A<strong><em> <\/em>behind-the-paper blog<\/strong> <strong>post<\/strong> has been published in the Nature Research Ecology &amp; Evolution Community here: <a href=\"https:\/\/natureecoevocommunity.nature.com\/posts\/bridging-the-gap-linking-biodiversity-ecosystem-functioning-experiments-to-real-world-ecosystems\">https:\/\/natureecoevocommunity.nature.com\/posts\/bridging-the-gap-linking-biodiversity-ecosystem-functioning-experiments-to-real-world-ecosystems<\/a><\/p>\n\n\n\n<h4>Reference:<\/h4>\n\n\n\n<p>Jochum, M., Fischer, M., Isbell, F. <em>et al.<\/em> The results of biodiversity\u2013ecosystem functioning experiments are realistic. <em>Nat Ecol Evol<\/em>  (2020). <a href=\"https:\/\/doi.org\/10.1038\/s41559-020-1280-9\">https:\/\/doi.org\/10.1038\/s41559-020-1280-9<\/a> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>A large body of research shows that biodiversity loss can reduce ecosystem functioning.
