Abstract As biodiversity is declining at an unprecedented rate, an important current scientific challenge is to understand
and predict the consequences of biodiversity loss. Here, we develop a theory that predicts the temporal
variability of community biomass from the properties of individual component species in monoculture.
Our theory shows that biodiversity stabilises ecosystems through three main mechanisms: (1) asynchrony in
species’ responses to environmental fluctuations, (2) reduced demographic stochasticity due to overyielding
in species mixtures and (3) reduced observation error (including spatial and sampling variability). Parameterised
with empirical data from four long-term grassland biodiversity experiments, our prediction explained
22–75% of the observed variability, and captured much of the effect of species richness. Richness stabilised
communities mainly by increasing community biomass and reducing the strength of demographic stochasticity.
Our approach calls for a re-evaluation of the mechanisms explaining the effects of biodiversity on
ecosystem stability.
