  bibo_abstract:
  - When divergent populations are connected by gene flow, the establishment of complete
    reproductive isolation usually requires the joint action of multiple barrier effects.
    One example where multiple barrier effects are coupled consists of a single trait
    that is under divergent natural selection and also mediates assortative mating.
    Such multiple‐effect traits can strongly reduce gene flow. However, there are
    few cases where patterns of assortative mating have been described quantitatively
    and their impact on gene flow has been determined. Two ecotypes of the coastal
    marine snail, Littorina saxatilis , occur in North Atlantic rocky‐shore habitats
    dominated by either crab predation or wave action. There is evidence for divergent
    natural selection acting on size, and size‐assortative mating has previously been
    documented. Here, we analyze the mating pattern in L. saxatilis with respect to
    size in intensively sampled transects across boundaries between the habitats.
    We show that the mating pattern is mostly conserved between ecotypes and that
    it generates both assortment and directional sexual selection for small male size.
    Using simulations, we show that the mating pattern can contribute to reproductive
    isolation between ecotypes but the barrier to gene flow is likely strengthened
    more by sexual selection than by assortment.@eng
