“…It has become clear that the recolonization events have sometimes been complex, having major effects on the phylogenetic structuring of European biota (reviewed in Hewitt, 1996;Comes and Kadereit, 1998). In Scandinavia, the prevalent determinant of the timing and patterning of phylogeographic case histories appears to have been the retreat of the ice sheet situated in Northern Sweden (Lundqvist and Mejdahl, 1995). It prevented movement between the western and eastern parts of Fennoscandia, and hence, when the ice melted, divergent genetic lineages were able to come into secondary contact.…”

“…In Europe, Fennoscandia was the last area to be recolonized (Lundqvist and Mejdahl, 1995). Consequently, because of their young age and the possible influence of founder events along the recolonization route, the genetic diversity of various organisms is commonly much lower in northern than in central European populations (Hewitt, 1996(Hewitt, , 2004Merilä et al, 1996;Palo et al, 2004).…”

“…The inner parts of Troms were deglaciated before 9 14 C kyr BP (e.g. Corner, 1980;Lundqvist and Mejdahl, 1995); thus, unit tB time includes the downwasting. An analogous situation is recorded offshore Baffin Island.…”

Late Weichselian and Holocene sediment flux and sedimentation rates in a continental-shelf trough, Andfjord, and its inshore continuation, Vågsfjord, North Norway, have been analysed. The study is based on sediment cores and high-resolution acoustic data. Andfjord was deglaciated between 14.6 and 13 14 C kyr BP (17.5 and 15.6 calibrated (cal.) kyr BP), the Vågsfjord basin before 12.5 14 C kyr BP (14.7 cal. kyr BP), and the heads of the inner tributary fjords about 9.7 14 C kyr BP (11.2 cal. kyr BP). In Andfjord, five seismostratigraphical units are correlated to a radiocarbon dated lithostratigraphy. Three seismostratigraphical units are recognised in Vågsfjord. A total volume of 23 km 3 post-glacial glacimarine and marine sediments was mapped in the study area, of which 80% are of Late Weichselian origin. Sedimentation rates in outer Andfjord indicate reduced sediment accumulation with increasing distance from the ice margin. The Late Weichselian sediment flux and sedimentation rates are significantly higher in Vågsfjord than Andfjord. Basin morphology, the position of the ice front and the timing of deglaciation are assumed to be the reasons for this. Late Weichselian sedimentation rates in Andfjord and Vågsfjord are comparable to modern subpolar glacimarine environments of Greenland, Baffin Island and Spitsbergen. Downwasting of the Fennoscandian Ice Sheet, and winnowing of the banks owing to the full introduction of the Norwegian Current, caused very high sedimentation rates in parts of the Andfjord trough at the Late Weichselian-Holocene boundary. Holocene sediment flux and sedimentation rates in Andfjord are about half the amount found in Vågsfjord, and about one-tenth the amount of Late Weichselian values. A strong bottom current system, established at the Late Weichselian-Holocene boundary, caused erosion of the Late Weichselian sediments and an asymmetric Holocene sediment distribution.

“…By contrast, the post-glacial colonization routes from these refugia, which have been proposed over the last decade, are not unanimously accepted (Taberlet et al, 1998;Hewitt, 1999). Northern Europe was the last region to become free of ice (Lundqvist and Mejdahl, 1995) and, consequently, was colonized more recently than southern regions. In northern populations, different phylogeographical patterns have been observed in terrestrial and aquatic organisms, presumably reflecting their different ecological requirements.…”
