Measuring recent effective gene flow among large populations in Pinus sylvestris: Local pollen shedding does not preclude substantial long-distance pollen immigration.
The estimation of recent gene flow rates among vast and often weakly genetically differentiated tree populations remains a great challenge.Yet, empirical information would help understanding the interaction between Frypans gene flow and local adaptation in present-day non-equilibrium forests.We investigate here recent gene flow rates between two la
