Topological properties of food webs: from real data to community assembly models
We explore patterns of trophic connections between species in the largest and highest-quality empirical food webs to date, introducing a new topological property called the link distribution frequency (i.e. degree distribution), defined as the frequency of species SL with L links. Non-trivial differences are shown in link distribution frequencies between species-rich and species-poor communitie...
متن کاملTopological structure and interaction strengths in model food webs
We report the results of carrying out a large number of simulations on a coevolutionary model of multispecies communities. A wide range of parameter values were investigated which allowed a rather complete picture of the change in behaviour of the model as these parameters were varied to be built up. Our main interest was in the nature of the community food webs constructed via the simulations....
متن کاملFood webs
Ecosystems, whether they are forests, lakes or coral reefs, consist of a diverse range of species that interact with each other in many ways. As ecologists we want to understand how these complex systems function as a whole and how they respond to human impacts such as harvesting and environmental change. A mechanistic understanding of the underlying biological processes will allow us to predic...
متن کاملEcology: Engineered food webs
An important new study shows that, in a food web, the strengths and arrangement of the interactions between species are determining factors of stability of the system.
