Results of the Bootstrap method for various basins. Only points corresponding to zones falling outside the grey boxes reflect significant changes in relative abundance of species. Arrows highlight in which direction to look for the relative abundance calculations when going from the Tenuicostatum (post-Pli-Toa) to the Falciferum Zone (post-TOAE). An enlarged version can be found in the supplementary material (Fig. S9)
