Changes in the position of the 321 plots sampled both in 1976 and 2006 along the first two axes of the co-inertia analysis with bivariate SD-ellipses and their centroids grouping plots according to sampling year and forest (North and South separately). Full symbol North Forest, open symbol South Forest, triangle 1976, circle 2006. Embeded mean scores (and confidence interval) along the two axes of the North and South Forest; arrows indicate the trajectory from 1976 to 2006
