    "abstract": "We investigate the relationship between the nested organization of\nmutualistic systems and their robustness against the extinction of species. We\nestablish that a nested pattern of contacts is the best possible one as far as\nrobustness is concerned, but only when the least linked species have the\ngreater probability of becoming extinct. We introduce a coefficient that\nprovides a quantitative measure of the robustness of a mutualistic system.",
