This paper presents a stress-based speciation model implemented within LifeDrop, a virtual world with bioinspired agents. In this model, individuals are distributed among species separated by a “barrier” mechanism preventing the reproduction between individuals of different species. An analysis of species dynamics in relation to stress is presented. Results show diversity maintenance and a reactive capacity during crisis situations favoring the emergence of new species.
