Integrating evolution into ecological modelling: accommodating phenotypic changes in agent based models.

Evolutionary change is a characteristic of living organisms and forms one of the ways in which species adapt to changed conditions. However, most ecological models do not incorporate this ubiquitous phenomenon. We have developed a model that takes a 'phenotypic gambit' approach and focuses...

description	Evolutionary change is a characteristic of living organisms and forms one of the ways in which species adapt to changed conditions.
