The mess in this chart is caused by "bad simulations". The burnin period should be long enough to allow age-structure equilibrium for the specific vital rates. Furthermore a big number of replicates is needed to smooth this chart.
In optimal situation, this chart should show parallel lines (age-structure equlibrium. Culling would produce interferences in this equilibrium.
PS. I will provide a standard config that would have the age-struct eq. at the beginning of the simulation.
