Formation of clusters at colonization of the area by the two-aged population

We study the model of spatial-temporal dynamics of populations with age structure on a one-dimensional area. We show that the type of dynamics is determined by demographic and migration parameters, as well as by the initial numbers of individuals in different parts of the area. It is shown that during colonization of the initially empty area, the main type dynamics is cluster synchronization including chimeras. Under certain parameters it demonstrates stability and can exist for a long time. Or, there is a rapid desynchronization, and incoherent modes arise.
