abstract = {Multiple Quaternary glacial refugia in the Iberian Peninsula, commonly known as “refugia
within refugia”, allowed diverging populations to come into contact and admix, potentially
boosting substantial mito-nuclear discordances. In this study, we employ a comprehensive
set of mitochondrial and nuclear markers to shed light onto the drivers of geographical differentiation
in Iberian high mountain populations of the midwife toads Alytes obstetricans and
A. almogavarii from the Pyrenees, Picos de Europa and Guadarrama Mountains. In the
three analysed mountain regions, we detected evidence of extensive mito-nuclear discordances
and/or admixture between taxa. Clustering analyses identified three major divergent
lineages in the Pyrenees (corresponding to the eastern, central and central-western Pyrenees),
which possibly recurrently expanded and admixed during the succession of glacialinterglacial
periods that characterised the Late Pleistocene, and that currently follow a ringshaped
diversification pattern. On the other hand, populations from the Picos de Europa
mountains (NW Iberian Peninsula) showed a mitochondrial affinity to central-western Pyrenean
populations and a nuclear affinity to populations from the central Iberian Peninsula,
suggesting a likely admixed origin for Picos de Europa populations. Finally, populations
from the Guadarrama Mountain Range (central Iberian Peninsula) were depleted of genetic
diversity, possibly as a consequence of a recent epidemic of chytridiomycosis. This work
highlights the complex evolutionary history that shaped the current genetic composition of
high mountain populations, and underscores the importance of using a multilocus approach
to better infer the dynamics of population divergence.},
