Metrics used to compare the structure of ant-plant mutualist networks in Continuous Forest (CF) and Forest Fragments (FF) and results of statistical analyses.

1See (10) for a complete description. s = number of species in the web and b•k and bk• represent column sum and row sums, respectively, of the plant/ant matrix, i.e., the total number of individuals associated with taxon k. 2Nestedness ranges from 0 to 100, with 0 being most nested and 100 indicating complete randomness. 3Weighted nestedness ranges from 0 to 1, where 1 is the most nested.
