TY - JOUR JF - Advances in Complex Systems UR - http://dx.doi.org/10.1142/S0219525911003116 IS - 04 N2 - In this work we analyze the topological and dynamical properties of a simple model of complex food webs, namely the niche model. In order to underline competition among species, we introduce "prey" and "predators" weighted overlap graphs derived from the niche model and compare synthetic food webs with real data. Doing so, we find new tests for the goodness of synthetic food web models and indicate a possible direction of improvement for existing ones. We then exploit the weighted overlap graphs to define a competition kernel for Lotka?Volterra population dynamics and find that for such a model the stability of food webs decreases with its ecological complexity.
