Modelling eco-systems with Google search tool
August 7, 2008
The Google PageRank formula can be used to model changes to the structure of food webs in an eco-system.
Eco-systems often contain many different species which depend on each other in complex ways. Working out how population changes and extinctions affect the food web is difficult. But finding out which species are key predators and prey in these webs is vital if species or eco-systems are to be protected.
