“…Geological evidence suggests that two permafrost‐free areas offered possible refugia in southwestern and in southeastern France during the LGM (Van Vliet‐Lanoë & Hallegouët ). Even if several plants and invertebrates were able to survive in ice‐covered regions using well‐exposed rocky emergences during the LGM (nunataks; Stehlik et al .…”

“…), which is limited to France, western and central Switzerland, Belgium, westernmost Austria and southwestern Germany. During the LGM (26–200 kya), however, the current distribution of this clade was covered by ice sheets (the Alps, the Jura Mountains and the top of the Massif Central; Van Vliet‐Lanoë & Hallegouët ) or with permafrost (Van Vliet‐Lanoë & Hallegouët ; Clark et al . ).…”

Postglacial recolonization in a cold climate specialist in western Europe: patterns of genetic diversity in the adder (Vipera berus) support the central–marginal hypothesis

Understanding the impact of postglacial recolonization on genetic diversity is essential in explaining current patterns of genetic variation. The central-marginal hypothesis (CMH) predicts a reduction in genetic diversity from the core of the distribution to peripheral populations, as well as reduced connectivity between peripheral populations. While the CMH has received considerable empirical support, its broad applicability is still debated and alternative hypotheses predict different spatial patterns of genetic diversity. Using microsatellite markers, we analysed the genetic diversity of the adder (Vipera berus) in western Europe to reconstruct postglacial recolonization. Approximate Bayesian Computation (ABC) analyses suggested a postglacial recolonization from two routes: a western route from the Atlantic Coast up to Belgium and a central route from the Massif Central to the Alps. This cold-adapted species likely used two isolated glacial refugia in southern France, in permafrost-free areas during the last glacial maximum. Adder populations further from putative glacial refugia had lower genetic diversity and reduced connectivity; therefore, our results support the predictions of the CMH. Our study also illustrates the utility of highly variable nuclear markers, such as microsatellites, and ABC to test competing recolonization hypotheses.

“…European landscape and especially the Paris basin was located in a zone of continuous permafrost extent (Dylik & Maarleveld, 1976;Van Vliet-Lanoë & Hallégouët, 2001) during the last glaciation, which probably extended further south during the coldest part of the Middle Pleistocene -Marine Isotopic Stages (MIS) 12 and 10. MIS 8 (Saalian II) is brief but very cold and arid, whereas the MIS 6 (Saalian III) is much less arid and colder toward its end (Seidenkrantz et al, 1996).…”

“…Usually thermal contraction proceeds in ice-rich sediment due to abrupt temperature drop (Lachenbruch, 1962;Allard & Kasper, 1998). During glacial times, European permafrost is generally ice-poor (Van Vliet-Lanoë & Hallégouët, 2001) and thermal cracking only proceeds on depressions fed by lateral slope seepage, for example from a sandy reservoir and by snowmelt supply. Moreover, patterned grounds such as stone circles (Washburn, 1979) are common on limestone affected by ice-rich permafrost, promoting frost shattering in the active layer.…”

GIS analysis of the French database of Pleistocene periglacial features allows an improved evaluation of the maximum extent of past permafrost. The distribution of typical ice-wedge pseudomorphs does not extend south of 47°N and therefore suggests that widespread discontinuous permafrost did not affect the regions south of the Paris Basin. The exclusive presence of sand wedges with primary infill between 45 and 47°N, mainly in the periphery of coversand areas, suggests that thermal contraction cracking of the ground occurred together with sand drifting in a context of deep seasonal frost or sporadic discontinuous permafrost, unfavourable for the growth of significant ground-ice bodies. The latitudinal variation of the wedge dimensions clearly shows that the sand wedges were located in the southern margin of the area affected by thermal contraction. The proposed map of Pleistocene permafrost in France partially reconciles field data with palaeoclimatic simulations. The remaining discrepancies may arise primarily from the time lag between the Last Permafrost Maximum (c. 31-24 ka) and the Last Glacial Maximum (21 ka).
