Many invasions succeed because of initially favorable environmental conditions. This talk will describe simple models that explore the potential for successful establishment via evolutionary change in environments that are initially hostile to the invader. The theory suggests that the influence of population dynamics on adaptive evolution tends to severely restrict the scope for successful invasions in environments that are initially demographic sinks.
