Individual variability and persistence of competing species in resource rich environment: an individual-based model

Abstract

The results of the individual-based model are presented, which show that in resource rich environments we can expect a greater diversity of competing primary consumers species. The condition for this is individual variability in the population of each competitor. The number of competing species that forms a persistent community depends on how large the individual variability is and on the type of resources for which the species compete. When unexploited resources have exponential dynamics, a persistent community composed of less variable competitors can be created than when resources have logistic dynamics.
