On the Evolution of Structure in Ecological Networks
Author(s): Matt Labrum ,Terry Soule ,Aaron Blue ,Stephen Krone

Subject(s): CX.18



Previous research on simulated ecological networks has focused on things like the distribution of links between species, without generally categorizing the types of inter-species relationships that develop, unless those relationships are of some predesigned form (e.g., food webs). In this work we use a model system to examine the specific types and numbers of interactions between species and how these affect network stability and evolution. For example, we report on the numbers of predator-prey, competitive, symbiotic, and more complex cyclic relationships that develop in randomly initialized communities, with and without the introduction of novel species over the course of the simulation.
