  bibo_abstract:
  - Hybrid zones represent evolutionary laboratories, where recombination brings together
    alleles in combinations which have not previously been tested by selection. This
    provides an excellent opportunity to test the effect of molecular variation on
    fitness, and how this variation is able to spread through populations in a natural
    context. The snapdragon Antirrhinum majus is polymorphic in the wild for two loci
    controlling the distribution of yellow and magenta floral pigments. Where the
    yellow A. m. striatum and the magenta A. m. pseudomajus meet along a valley in
    the Spanish Pyrenees they form a stable hybrid zone Alleles at these loci recombine
    to give striking transgressive variation for flower colour. The sharp transition
    in phenotype over ~1km implies strong selection maintaining the hybrid zone. An
    indirect assay of pollinator visitation in the field found that pollinators forage
    in a positive-frequency dependent manner on Antirrhinum, matching previous data
    on fruit set. Experimental arrays and paternity analysis of wild-pollinated seeds
    demonstrated assortative mating for pigmentation alleles, and that pollinator
    behaviour alone is sufficient to explain this pattern. Selection by pollinators
    should be sufficiently strong to maintain the hybrid zone, although other mechanisms
    may be at work. At a broader scale I examined evolutionary transitions between
    yellow and anthocyanin pigmentation in the tribe Antirrhinae, and found that selection
    has acted strate that pollinators are a major determinant of reproductive success
    and mating patterns in wild Antirrhinum.@eng
