Fig. 1. Absolute values of nestedness from null models constructed based on fully nested (A, B) and uniformly distributed matrices (C, D) (mean ± SD). Backtrack, fixed row-fixed column; c0, equiprobable row-fixed column; IM, initial matrix; r0, fixed row- equiprobable column; r00, equiprobable row-equiprobable column. ***, significant at 0.001 level.
