title: Seed migration and the structure of plant populations : An experimental study on Thymus vulgaris L.
abstract: We use chemical typing to compare sub-populations of thyme (Thymus vulgaris L.) growing in the channels of several ravines where seed migration is expected from sub-populations on the plateu to associated basin subpopulations. The results indicate that seed migration does occur. However, there is little effective gene flow between sub-populations. We discuss the implications of restricted gene flow for population dynamics and structure.
