We have just published our paper “Olesen, J.M., Bascompte, J., Dupont, Y., and Jordano, P. 2007. The modularity of pollination networks. Proceedings of the National Academy of Sciences USA, 104: 19891-19896”. These are great news since it represents a very nice work lead by Jens. Here we relate the concept of moodularity to our previous work on nestedness in mutualistic plant-animal assemblages.
