Table 1 Summary of the explanatory power (i.e. % of deviance explained) of the Generalized Additive Models (GAMs) fit to model the global gradients log-transformed Equivalent Spherical Diameter (ESD, µm) as a function of the ten environmental covariates selected, measured for the zooplankton groups and for the plankton nets that sampled enough stations (> 30) and enough individuals (> 20) per group.

The significant covariates (p < 0.05) were ranked based on their relative F statistic and are shown. The GAMs displaying a % of deviance explained > 40% were clustered into four groups based on the shape of the smoothing curves of each covariate (Fig. S10).
