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 aij
= -1 and aji = 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.
