 Remarkably, our results indicate that, from 2003 on, the abundances of a recently-defined class of bipartite motifs assume values progressively closer to the ones predicted by a null model which preserves only basic features of the observed structure, completely randomizing the rest.

 Remarkably, our results point out the presence of early structural changes in the WTW topology: from 2003 on, the abundances of a recently-defined class of bipartite motifs assume values progressively closer to the ones predicted by a null model which preserves only basic features of the observed structure, completely randomizing the rest.
