Abstract

Summary: Extensive research shows that more species‐rich assemblages are generally more productive and efficient in resource use than comparable assemblages with fewer species. But the question of how diversity simultaneously affects the wide variety of ecological functions that ecosystems perform remains relatively understudied. It presents several analytical and empirical challenges that remain unresolved. In particular, researchers have developed several disparate metrics to quantify multifunctionality, each characterizing different aspects of the concept and each with pros and cons. We compare four approaches to characterizing multifunctionality and its dependence on biodiversity, quantifying (i) magnitudes of multiple individual functions separately, (ii) the extent to which different species promote different functions, (iii) the average level of a suite of functions and (iv) the number of functions that simultaneously exceeds a critical threshold. We illustrate each approach using data from the pan‐European BIODEPTH experiment and the R multifunc package developed for this purpose, evaluate the strengths and weaknesses of each approach and implement several methodological improvements. We conclude that an extension of the fourth approach that systematically explores all possible threshold values provides the most comprehensive description of multifunctionality to date. We outline this method and recommend its use in future research.

  • Similar complementarity has been observed in diverse assemblages where species can interact.

    “similar complementarity has been observed in diverse assemblages where species can interact”
  • The results support species richness as an important driver of ecosystem functioning and reveal an overlooked effect of total abundance on supporting and provisioning services.

    “Overall, our results support the important role of species richness 1-2,14- 17, 22, 25 as a driver of ecosystem functioning, while also highlighting the overlooked effect of total abundance on supporting and provisioning services.”
  • These results provide evidence that biodiversity is an important driver of ecosystem functioning relative to environmental factors, for multiple services in realistic landscapes and not only individual functions in small-scale experiments.

    “These results provide evidence that biodiversity is an important driver of ecosystem functioning in comparison with environmental factors, not only for individual functions in small-scale experiments 7,8 , but also for multiple ecosystem services in realistic landscapes (see also refs.15, 22).”
  • The EMF index, calculated from functions that are often correlated with one another, does not provide a single best metric of EMF.

    “We acknowledge that the EMF index, calculated from functions that are often correlated with one other (Supplementary Figs 13 and 14), does not provide a single best metric of EMF21.”
  • There are several ways to estimate the relationship between biodiversity and EMF: the single functions approach, turnover approach, averaging approach and threshold approach.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
