Relationship between species asynchrony and yield stability at Wexford (A) and Zürich (B) under rainfed control and drought conditions. The stability index S = μ/σ was computed with μ and σ being the mean and the standard deviation across all harvests. rho: spearman rank correlation. At Wexford under drought, four of the two-species mixtures had missing data for individual species (no asynchrony value computed).
