text: 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.
