A plot of the fraction of species combinations showing significance of correlated breaks (Y-axis) against the threshold for number of breaks in the variable species (X-axis). This is based on the 6 species analysis. The same trend follows in other analyses as well. As we consider combinations with more breaks in the variable species, the fraction that show significance grows steadily. (a) FBP, (b) FBR. The numeric label on each bar indicates the number of combinations that are above the threshold.
