Abstract: 

We continue our analysis of evolutionary models aimed at explaining partial migration, the phenomenon where some individuals in a population migrate between breeding seasons, but others do not. Whereas we showed before that partial migration can be caused by negative density dependence alone, we will now consider the effects on partial migration of how density dependence acts: within-types, between-types, or a mixed form. In some, but not all of these cases, we show that partial migration can still evolve, and we derive precise conditions taking the form of sharp inequalities with natural biological interpretation, to distinguish between them.
