“…The two species of lemmings cannot be distinguished from palaeontological data (Kowalski 1995). However, Pleistocene fossil records indicate that, during the glacial periods, Lemmus was continuously distributed in periglacial areas of continental West Europe (Bennike et al 1994;cf. Kowalski 1995) and presumably colonized Scandinavia from continental Europe during the Late Quaternary period (cf.…”

“…Consistent with this, there is no support for postglacial colonization of Scandinavia by the Norwegian lemming from the fossil records available to date. While fossils of Lemmus have been recorded from the periglacial area in Denmark before the last glacial maximum (Bennike et al 1994), lemmings are lacking in the Danish small mammal fauna (11.5 kyr BP) (Aaris-SÖrensen 1995) during the time of post-glacial colonization of Scandinavia by mammals from the south via a land bridge (cf. Jaarola et al 1999).…”

In order to evaluate the biogeographical hypothesis that the Norwegian lemming (Lemmus lemmus) survived the last glacial period in some Scandinavian refugia, we examined variation in the nucleotide sequence of the mitochondrial control region (402 base pairs (bp)) and the cytochrome b (cyt b) region (633 bp) in Norwegian and Siberian (Lemmus sibiricus) lemmings. The phylogenetic distinction and cyt b divergence estimate of 1.8% between the Norwegian and Siberian lemmings suggest that their separation pre-dated the last glaciation and imply that the Norwegian lemming is probably a relic of the Pleistocene populations from Western Europe. The star-like control region phylogeny and low mitochondrial DNA diversity in the Norwegian lemming indicate a reduction in its historical e¡ective size followed by population expansion. The average estimate of post-bottleneck time (19^21kyr) is close to the last glacial maximum (18^22 kyr BP). Taking these ¢ndings and the fossil records into consideration, it seems likely that, after colonization of Scandinavia in the Late Pleistocene, the Norwegian lemming su¡ered a reduction in its population e¡ective size and survived the last glacial maximum in some local Scandinavian refugia, as suggested by early biogeographical work.

“…The drop in the count of the P. filiformis and P. praelongus endocarps at a later stage shows that phytocenoses composed of these species declined. The presence, especially in the older profiles, of Potamogeton filiformis suggests that the lake was cool and mesotrophic (Velichkevich and Zastawniak 2006;Kolstrup 1979;Matuszkiewicz 2001) with clear water, abundant in CaCO 3 (Bennike et al 1994) and with a pH higher than 7 (Lang 1994).…”

The Late Vistulian and Holocene evolution of Jezioro Lake: a record of environmental change in southern Poland found in deposits and landforms

et al. 2012

Jezioro Lake is the only natural lake in southern Poland outside mountainous areas to have existed continuously since the Pleistocene. The record of environmental change in the Late Vistulian (Weichselian) and Holocene is preserved in the deposits and landforms around the lake. This paper presents the results of paleogeographical and paleoecological research that emabled us to reconstruct the history of the Jezioro Lake. At the end of the Vistulian period, the outlet of the lake was blocked by a parabolic dune moving in from the west. Limnic sedimentation was evident in the sediment core at all levels from the Holocene, with remains of Cladocera, Chironomidae larvae, and aquatic plants. The lake did not disappear at that time, although its area decreased by a factor of 12 by the end of the period. Paleobotanical research permitted the reconstruction of sequences of plant communities and changes in nutrient status and water level. An initial oligotrophic lake, as indicated by the presence of Isoe¨tes lacustris L., changed to a eutrophic lake, as indicated by the presence of Potamogeton natans L. and Nuphar sp., then the lake progressed to the present-day dystrophic lake that is surrounded by a swamp. The profile of organic deposits contains a record of environmental change at least since the Younger Dryas in southern Poland.
