Researchers have adapted Google’s web-ranking system to help in food webs. This new system could predict which groups of species would crash their food web if they became extinct. SFI Professor Jennifer Dunne calls this a “novel, exciting contribution.” Dunne goes on to say, “The problem of how ecosystems are likely to respond to the loss of species is quite important, particularly in light of how many different ways human activities are resulting in the local extinctions of populations.”
