Scientists find universal rules for food-web stability

The findings, published in this week's issue of Science , conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. The computations also reveal that small ecosystems follow other rules than large ecosystems: differences in th...
