The food web shows how matter and energy flow among different kinds of organism in the ecosystem. I have developed an individual-based community model called Uqbar to investigate how the topology of the food web is determined and how it evolves over time.

- A simplified, non-evolving version of Uqbar with one or two species at each of three trophic levels can be run as either a single community or a metacommunity.
