Gene flow experiment

Preliminary analyses for the gene flow experiment have been completed. This experiment, conducted by postdoc Anne-Marie Labouche, considers the effects of pollen limitation and pollen competition on offspring number and quality as a function of plant density. Apart from demonstrating pollen limitation in Mercurialis, the experiment showed larger pollen flow distances than expected and several other interesting features related to M. annua mating system.
