A spatially explicit model for competition among specialists and generalists in a heterogeneous environment [PDF]
, 2006 Competition is a major force in structuring ecological communities. The strength of competition can be measured using the concept of a niche. A niche comprises the set of requirements of an organism in terms of habitat, environment and functional role ...

Population Dynamics on Complex Food Webs [PDF]
, 2011 In this work we analyse 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
