Table 2. Global and local indicators used in the current food web analysis, represented by index name, formula, definition, and the reference from which index was obtained

Index Definition Reference
Global indicators
 Diameter Longest distance between nodes Csardi & Nepusz (2006)
 Average path length The average distance between any pair of nodes Travers & Milgram (1969)
 Density Ratio of the number of edges and the number of possible edges, which indicates the network complexity Wasserman & Faust (1994)
 Clustering Probability that nodes tend to group together in a networks Barrat et al. (2004)
Local indicators
 Degree Indicates the number of connections between pairs of nodes and is the sum of the connections between predators and prey. Estupiñán-Montaño (2022)
 Closeness Indicates the speed transmission of information through the food web. The lower Ci indicates quicker transmission through the network than those with higher values. Wasserman & Faust (1994)
 Betweenness This intermediation index represents the capacity of the network to control the exchange of information. Wasserman & Faust (1994)
 Eigenvector centrality Measures the influence of a node in a network, considering not only the total number of adjacent nodes but also considering their importance. Bihari & Pandia (2015)
