Speciation typically involves a stage in which species can still exchange
genetic material. Interspecific gene flow is facilitated by the hybrid
zones that such species establish upon secondary contact. If one member of
a hybridizing species pair displaces the other, their hybrid zone would
move across the landscape. Although theory predicts that moving hybrid
zones quickly stagnate, hybrid zones tracked over one or a few decades do
not always follow such a limitation. This suggests that hybrid zones have
the potential to traverse considerable distances over extended periods of
time. When hybrid zones move, introgression is predicted to result in
biased gene flow of selectively neutral alleles, from the receding species
into the advancing species. We test for such a genomic footprint of hybrid
zone movement in a pair of crested newt species (genus Triturus) for which
we have a priori support for westward hybrid zone movement. We perform a
multilocus phylogeographical survey and conduct Bayesian clustering
analysis, estimation of ancestry and heterozygosity, and geographical
cline analysis. In a 600 km wide area east of the present day hybrid zone
a genomic footprint constitutes empirical evidence consistent with
westward hybrid zone movement. The crested newt case suggests that hybrid
zone movement can occur over an extensive span of time and space.
Inferring hybrid zone movement provides fundamental insight into
historical biogeography and the speciation process, and we anticipate that
hybrid zones will prove to be far more mobile than currently appreciated.
