Abstract
We have developed an individual-based evolving predator-prey ecosystem
simulation that integrates, for the first time, a complex individual
behaviour model, an evolutionary mechanism and a speciation process, at
an acceptable computational cost. In this article, we analyse the
species abundance patterns observed in the communities generated by our
simulation, based on Fisher's logseries. We propose a rigorous
methodology for testing abundance data against the logseries. We show
that our simulation produces coherent results, in terms of relative
species abundance, when compared to classical ecological patterns. Some
preliminary results are also provided about how our simulation is
supporting ecological field results. (C) 2009 Elsevier B.V. All rights
