Dynamics of range expansion

Selective pressures at range margins of expanding populations may differ from those in the core of the range, particularly on traits like reproductive rate and dispersal. These are the same traits that drive the ecological dynamics of expansion. Thus, the stage is set for feedbacks between evolution of life history traits and ecology of population spatial spread. Most studies do not account these feedbacks. Are we missing an important piece of the puzzle? I review theory and data on eco-evolutionary feedbacks during range expansion and consider their potential importance in studies of biological invasions and responses to climate change.
