H′2: network selectiveness; WNODF: weighted nestedness; Q: quantitative modularity. The significance of observed results was tested by constructing 1000 randomized networks with identical margin totals as the empirical networks and comparing the observed and random values using the null model ‘r2d’ (*P < 0.05; ***P < 0.001).
