Sample plot of the co-inertia analysis performed on the PCA of the phytoplankton assemblage and the PCA performed on the zooplankton assemblage. The most dominant taxa are underlined for phytoplankton and in italic for zooplankton. Time periods (P1 to P4) are grouped by their barycenter, with periods seen from zooplankton (blue points) and from phytoplankton (gray squares). Detailed plots of co-inertia with all plankton taxa are shown in Fig. S4.
