Population models of mathematical ecogenetics
Demographic systems of genetically distinguished interacting populations are proposed and investigated.
These ecosystems can coexist at suitable stable equilibria or through persistent oscillations.
A suitably defined parameter, the ''invasion number'', can be identified, that when exceeding a threshold destabilizes these equilibria.
