  1. Output from linear mixed models with predator-prey mass ratio (PPMR), predator body mass and abundance-weighted average prey body mass in predator stomachs as response variables (all log10). SST represents sea-surface temperature. R2m and R2c represent the Nakagawa’s marginal and conditional model R2 values, respectively.
