Food Web Database

The food webs are based on published studies of various types of habitat. The original food web matrix is not a square matrix.  It contains m columns of predators and n rows of preys with a 1 at the intersection to indicate a direct feeding relation. We converted the original food web matrix into a community matrix and set a_ij = -1 and a_ji = 1 if species i feeds on species j. You can decide if a self-loop is added to each species or to the primary producer.
