Fig. 5From: Tradeoff between robustness and elaboration in carotenoid networks produces cycles of avian color diversificationCharacteristics of the same subset of global carotenoid network (Additional file 4: Figure S1) as expressed in combined “bacterial”, “algae”, “plants”, “animals”, and “birds only” networks. For the similar number of nodes in the subset of global network (a), birds have less connected (b, c) and more modular (d) network (data in Additional file 1: Appendix S1)Back to article page
