Complex systems of intracellular biochemical reactions have a central role in regulating cell identities and functions. Biochemical reaction systems are typically studied using the language and tools of graph theory. However, graph representations only describe pairwise interactions between molecular species and so are not well suited to modelling complex sets of reactions that may involve numerous reactants and/or products.

A total of 255 longnosed skate Dipturus oxyrinchus caught in Sardinian waters (central‐western Mediterranean Sea), was analysed with respect to fish total length ( L T ), season and depth, in order to provide information on diet and feeding behaviour. Specimens ranging from 93 to 1153 mm L T , were collected at depths between 121 and 671 m, during experimental trawl surveys carried out from 2005 to 2010. The diet comprised cru...
