“…Similar changes of vegetation are dated back to 11,500 cal yr BP and coincide with the Younger Dryas/Preboreal boundary according to palynological data and correspond to the climate warming in the North Atlantic region (Björck et al 1996(Björck et al , 2002.…”

Pollen, plant macroscopic fossil and carbonate analyses supplemented with 14 C dating were applied for sediment sections of Lopaičiai Kettle and Pakastuva Lake. The new data obtained from two sediment cores were used to reconstruct vegetation cover and environmental changes during Lateglacial and Holocene in the Samogitian Upland (NW Lithuania). Different burial conditions of dead-ice blocks caused different times of lake sediment start in studied sites. The depositional and vegetation history is traced at the inception of preAllerød time in sediment section from the Lopaičiai core. However, sediment section from the Pakastuva core provides paleoenvironmental information starting only from the very beginning of Holocene. The study results shed more light on the environmental development during the Lateglacial and Holocene of the specific ice marginal area, which belongs to interlobate insular upland.

“…The southern Baltic salmon populations were geographically closest to Atlantic waters after the Närke Strait route was closed for migration at 11 000 years BP (Björck et al 2002) and the Danish Straits opened. However, this Atlantic colonization direction is unlikely because the mtDNA is similar to that of the eastern populations.…”

The genetic structure and phylogeography of Atlantic salmon (Salmo salar) across the Baltic Sea basin and neighbouring areas (eastern Atlantic Ocean, North Sea, Barents Sea, White Sea, and two Russian lakes, Onega and Ladoga) were studied to resolve the partly contradictory hypotheses of the species' postglacial colonization history. Thirty-eight populations (total of 2180 individuals) were studied for nine DNA microsatellite loci. Within the Baltic Sea, the anadromous populations formed three clear groups, corresponding to the northern (Gulf of Bothnia), eastern (Gulf of Finland and eastern Baltic Main Basin), and southern regions (western Baltic Main Basin). The genetic differences among these three groups were clearly greater (G GB 5.6%; G GB being the proportion of diversity components between regions within basins) than were those among population groups in the eastern Atlantic Ocean (G GB 2.2%) from Ireland to the White Sea. The isolation-by-distance model explained part of the differentiation within, but not between, the regions. The results strongly indicate colonization of the Baltic Sea by at least three glacial lineages. Potential refugium areas for each lineage are proposed.Résumé : Nous avons étudié la structure génétique et la phylogéographie du saumon atlantique (Salmo salar) de part en part du bassin de la Baltique et dans les régions avoisinantes (est de l'Atlantique, mer de Barents, mer Blanche et deux lacs russes, les lacs Onega et Ladoga) pour résoudre les hypothèses en partie contradictoires sur l'histoire de la colonisation postglaciaire de l'espèce. Nous avons analysé neuf locus ADN microsatellites chez 2180 individus appartenant à 38 populations. Au sein de la Baltique, les populations anadromes forment trois groupes distincts qui correspondent aux régions du nord (golfe de Bothnie), de l'est (golfe de Finlande et bassin principal de l'est de la Baltique) et du sud (bassin principal de l'ouest de la Baltique). Les différences génétiques entre ces trois groupes sont nettement plus importantes (G GB 5,6 %; G GB représente la proportion d'éléments de diversité entre les régions à l'intérieur des bassins) que celles qui existent entre les groupes de populations de l'est de l'Atlantique (G GB 2,2 %), de l'Irlande à la mer Blanche. Le modèle de l'isolement en fonction de la distance explique une partie de la différentiation au sein des régions, mais non entre elles. Nos résultats indiquent fortement une colonisation de la Baltique par au moins trois lignées glaciaires. Nous proposons des zones possibles de refuge pour chaque lignée.[Traduit par la Rédaction] Säisä et al. 1904
