Analysis of the temporal dynamics of the principal spatial patterns (EOM 1, 3, 4, 5) and of the abundance for the cold season. Diagonal panels: auto-correlograms; Lower triangle panels: cross-correlograms. For all panels, the x-axis represents time lags in years (from 0 to 30 years) and the y-axis represents correlations. The horizontal black dashed line is at 1. For off diagonal panels, the horizontal dotted lines represent the correlations. The panels of the last line concerns the cross-correlograms of EOM weights with abundance and the auto correlogram for abundance (last panel). The horizontal red dashed lines represents the correlation between EOM weights and abundance. The linear model of coregionalisation is represented as a continuous line (nugget effect + slope). The isolated panel represents the correlation between abundance and EOM weights as a function of the nugget effect in the model.
