Emergence of multi-generational migration behavior by adaptiogenesis to environmental changes

The target of our study is the Monarch Butterfly, which is known for its multi-generational migration behavior: it migrates between southern Canada and Mexico over the course of one year within three to four generations. In spite of many reported studies, little is known about what influences their migration. We approach this subject by using an ecosystem model consisting of artificial agents and five areas. We simulate under the environmental condition that the average annual temperature rises every year, which is modeled on the current global temperature rise. Our agents emerge the migration behavior similar to the multi-generational migration of the actual Monarch. The migration process of the agents is discussed.
