The structure of the ecological network can be described by the S \(\times\) S matrix A = [a ij], where each element a ij describes the link between species i and species j, i.e., the effect that species j has on species i.In the most particular case of unweighted and undirected network, matrix A is symmetric (i.e., a ij = a ji) and its elements are either 0 or 1 (Newman 2010; Estrada 2012).
