Scientists Find Universal Rules For Food-web Stability
New findings, published in the journal Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels.... Natural ecosystems consist of interwoven food chains, in which individual animal or plant species function as predator or prey. Potential food webs not only differ by their species composition, but also vary in their stability. Observable food webs are stable food webs, with the relationships between their species remaining constant over relatively long periods of time.... Applying this innovative modeling approach ... the scientists have succeeded in discovering not just one, but several universal rules in the dynamics of ecosystems. "Food-web stability is enhanced when species at high trophic levels feed on multiple prey species and species at intermediate trophic levels are fed upon by multiple predator species," says Ulf Dieckmann of IIASA.

OK: biodiversity, interdependence, and varied predator-prey relationships yield ecosystem stability. Good work! Now: what happens when we screw it up?
