Foraging response either included the direction of the response (part FORAGING) or just its (directionless) magnitude (PLASTICITY). Type of the correlation coefficient used is indicated columnwise, r – Pearson’s correlation coefficient, ρ – Spearman’s correlation coefficient (rho). n – number of cases (species), p – p-value.
