“…The Baltic sea coastline is a novel environment that, after melting of the continental ice sheet, underwent dramatic changes driven by a dynamic equilibrium between rising global ocean levels and gradual uplift of the deglaciated land mass (Bj€ orck 1995). In its current place, it began to develop only ca 5700 years ago (Janke et al 1993;Wohlfarth et al 2008). It is thus plausible that the admixture event took part in the areas where both putative parents still co-occur and hybridize (i.e.…”

Northern glacial refugia and altitudinal niche divergence shape genome‐wide differentiation in the emerging plant model Arabidopsis arenosa

Quaternary climatic oscillations profoundly impacted temperate biodiversity. For many diverse yet undersampled areas, however, the consequences of this impact are still poorly known. In Europe, particular uncertainty surrounds the role of Balkans, a major hotspot of European diversity, in postglacial recolonization of more northerly areas, and the Carpathians, a debatable candidate for a northern 'cryptic' glacial refugium. Using genome-wide SNPs and microsatellites, we examined how the interplay of historical processes and niche shifts structured genetic diversity of diploid Arabidopsis arenosa, a little-known member of the plant model genus that occupies a wide niche range from sea level to alpine peaks across eastern temperate Europe. While the northern Balkans hosted one isolated endemic lineage, most of the genetic diversity was concentrated further north in the Pannonian Basin and the Carpathians, where it likely survived the last glaciation in northern refugia. Finally, a distinct postglacial environment in northern Europe was colonized by populations of admixed origin from the two Carpathian lineages. Niche differentiation along altitude-related bioclimatic gradients was the main trend in the phylogeny of A. arenosa. The most prominent niche shifts, however, characterized genetically only slightly divergent populations that expanded into narrowly defined alpine and northern coastal postglacial environments. Our study highlights the role of eastern central European mountains not only as refugia for unique temperate diversity but also sources for postglacial expansion into novel high-altitude and high-latitude niches. Knowledge of distinct genetic substructure of diploid A. arenosa also opens new opportunities for follow-up studies of this emerging model of evolutionary biology.

“…The sea-level change has affected the coastal lakes in the southern Baltic Sea region. Today, these lakes are separated from the Baltic Sea by Holocene barrier islands (Janke et al, 1993), which connect isolated Pleistocene islands (Kliewe and Janke, 1991). One of the coastal lakes is the Oder River estuary, a shallow lagoon with a surface area of approximately 1000 km 2 (Fig.…”

“…A continual build up of barrier islands in the Oder lagoon has been noted in the mineralogical composition of the sediments (Gingele and Leipe, 1997) and in the abundance of microfossils (Müller et al, 1996). Sedimentological studies have shown that, parallel to the decreasing inflow of water from the Baltic Sea, the salinity decreased, more organic-rich fine sediment was deposited, the shore vegetation spread over a larger area, and nutrient input increased (Kliewe and Janke, 1991;Janke et al, 1993).…”

Knowledge of sea-level change in the southern Baltic Sea region is important for understanding the variations in late Pleistocene and Holocene sea-level change across northern Europe. These variations are a consequence of the response of the Earth's crust to the deglaciation of Fennoscandia and of the water added to the oceans from the melting of all Pleistocene ice sheets. The sedimentological and geochemical composition of five sediment cores from the lagoonal Oder Estuary offers new observational evidence for sea-level change and coastal development in the southern Baltic Sea region. The combined use of several geochemical proxies (organic carbon, nitrogen, calcium carbonate and biogenic opal contents, Corg/S and Corg/N ratios, δ13C values of organic matter, and δ15N values) is a new approach for the study area. The chemical evidence of this multiproxy approach allows clear identification of several stages in the development of the lagoonal environment: postglacial lake stages with sandy sedimentation during the Older Dryas and the Allerød stades, lacustrine phases with high autochthonous productivity during the Atlantic stade, terrestrial stages with peat formation at the beginning of the Subboreal stade, sedimentation as a result of marine transgression, and brackish sedimentation after the formation of sand spits and barrier islands during the Subatlantic stade. The stages are the result of regional sea-level change owing to complex shoreline development. They support the tentative sea-level curve proposed nearly 20 years ago for the region. In addition, changes in Oder River input in response to climate conditions is monitored. Whereas high terrigenous input of organic matter from the Oder River occurred during periods of humid climate during the Allerød, Atlantic, and Subatlantic stades, Oder River discharge decreased with drier and cooler climate conditions during the Subboreal stade. Furthermore, the geochemical evidence points to local anomalies such as the significance of river input and additional sulfate supply into the Oder lagoon for the composition of the sediments. Overall, the results provide a framework for future studies, which would allow for a more detailed comparison with other, similar environments.
