A modeling preprint suggests that near-perfect correlations between species are not a universal sign of ecological instability; the signal depends on whether a slowly relaxing mode is visible above background fluctuations.

The analysis predicts shifted optima, asymmetric or potentially two-peaked effective fitness landscapes, and wider or displaced distributions of simulated trait outcomes.
