In generalized Lotka–Volterra communities, stable coexistence almost always requires overyielding; in four long-term biodiversity experiments, underyielding raised species-loss odds within two observations (pooled odds ratio 2.61).

The paper derives an analytical distribution of distances to the edge of species coexistence in Lotka-Volterra models, using interaction matrices and applies it to experimental plant community data.
