Links Between Ecosystem Multifunctionality and Above- and Belowground Biodiversity Mediated by Climate

Plant biodiversity is often correlated with ecosystem functioning in terrestrial ecosystems. However, little is known about the relative and combined effects of above- and belowground biodiversity on multiple ecosystem functions [e.g., ecosystem multifunctionality (EMF)] or how climate might mediate those relationships. A recent study teases apart the effects of biotic and abiotic factors, both above- and belowground, on EMF on the Tibetan Plateau in China. The researchers found that a suite of biotic and abiotic variables account for up to 86% of the EMF variation, with the combined effects of above- and belowground biodiversity accounting for 45% of the EMF variation. These results have two important implications: (1) including belowground biodiversity in models can improve the ability to explain and predict EMF, and (2) regional-scale variation in climate, and perhaps climate change, can determine, or at least modify, the effects of biodiversity on EMF in natural ecosystems.
