Scientists find universal rules for food-web stability

... developed a new method that allows them to efficiently analyze the impact of innumerable parameters on complex systems. "By using a method called generalized modeling, we examine whether a given food web can, in principle, be stable, i.e., whether its species can coexist in the long term," says Thilo Gross ...
