“…In the investigated area, altitude of this periglacial lake was around 140 m a.s.l., and it lowered to 130-128 m a.s.l. when the ice cover started to retreat (Baltrūnas et al, 2007).…”

“…The lowest altitudes are observed in the area of the former lake Dūbas and in the source area of the Ūla River valley. The highest altitudes are distributed in the northeast of the territory, where landforms of the Middle Pleistocene Medininkai (Warthe) glaciation are widespread (Baltrūnas et al, 2007). Prior to 1840, the whole area was drained via the River Katra westward (Linkevičienė, 2009), and the direction of the abovementioned Ūla inlet was opposite to that of the present day.…”

“…The continental ice sheet advanced and retreated several times during the last glacial period (Baltrūnas et al, 2007;Ehlers and Gibbard, 2004;Sibrava et al, 1986). Global behavior of the continental ice sheet caused dramatic changes in the hydrosphere of its surroundings, including the marginal area of the glaciation.…”

A reconstructed pattern of Lateglacial and Holocene hydrological changes in the area of the former lakes Dūbas, Pelesa and Matara is presented. The investigated basin is situated in southeastern Lithuania, beyond the marginal ridge of the Weichselian Glaciation, on the margin of the sandy plain that is the watershed between the Ūla and Katra rivers. Pollen analysis, radiocarbon dating, loss-on-ignition measurements and GIS-based simulation of water level fluctuations have been applied in order to obtain new information on the development of the Ūla–Katra watershed area. The results of multiproxy investigations revealed the history of the development and extinction of Dūbas, Pelesa and Matara lakes. A single basin, covering a large part of the study area, had formed after the retreat of the continental ice sheet from southeastern Lithuania. This basin was divided into three separate lakes during the Allerød Interstadial as a result of a drop in water level. Blocking of the drainage by aeolian sediments around the early Boreal caused another rise in the water-table and the successive merging of the separate lakes. Probably as a result of river capture, the single lake was drained abruptly after c. 2000 years. Another river-capture event in the 19th century caused abrupt drainage of the study area, which led to the final extinction of the three lakes.

“…Indeed, in wide areas of the North European Lowlands, late Pleistocene tills are overlain by several decimetres of sand-rich periglacial deposits (Schwan, 1986;Liedtke, 1993;Baltrunas et al, 2007). Because the cover sands (Decksande) are not homogenous but products of different processes including cyroturbation, solifluction and eolian inputs, their correlation with the Upper Head in the German highlands remains questionable (Bussemer, 1998).…”

Periglacial slope deposits (PSD) of Pleistocene age are one of the most widely distributed sediment types in nonglaciated mid-latitude regions. As diamictons of different genesis (geli-solifluction, cryoturbation, eolian transportation) they have a wide range of physical, chemical and mineralogical characteristics which are mainly controlled by bedrock geology, including saprolite. This paper reviews concepts used in Germany to study PSD stratigraphy and describes the different PSD units encountered (Upper Head, Middle Head, Lower Head). The paper is relevant to the understanding of PSDs in other midlatitude regions. Classical and new results concerning the age of PSDs show differences in the interpretation of Upper Head genesis. In terms of their ecological significance, case studies from eastern Bavaria illustrate the influence of PSDs on the character and intensity of slope hydrological processes as well as on the formation and distribution of soils. Presently important research questions include (1) the establishment of a genetically based classification of PSDs, (2) the intensification of dating studies on PSDs, and (3) the clarification of hydrological processes in PSDs.

“…In the middle and late Quaternary, successive glaciations in the Northern Hemisphere covered various and generally successively smaller areas of Eurasia (Różycki, 1972; Baltrūnas et al, 2007; Astakhov, 2013). The resulting landscape shows zonation, well marked in Germany, Poland, Belarus, Lithuania, Latvia, Estonia, and part of Russia (Lindner, 1987; Marks, 2011; Astakhov, 2013).…”

During the Pleistocene in the northern part of Europe and Asia, the presence of ice sheets not only limited the range of species but also influenced landscape and thus the contemporary habitat system that determines the pattern of biodiversity. The aim of the research was to find out whether and how a lowland landscape, which formed as a result of subsequent Pleistocene glaciations (five) that in Eurasia covered various and generally successively smaller areas, affected the genetic differentiation of a species. The research was carried out in eastern Poland on the root vole Microtus oeconomus (Arvicolinae, Rodentia), a model boreal and hygrophilous species. Samples were collected from 549 vole individuals at 33 locations. Based on the analysis of 12 microsatellite loci and the 908 bp of cytochrome b sequences (mitochondrial DNA), the genetic structure of M. oeconomus in the landscape zones of the Polish Lowlands was determined. The results show that the latitudinal variability of the relief in eastern Poland (resulting from different ranges of Pleistocene ice sheets) and the related specific configuration of hydrogenic habitats are reflected in the genetic differentiation of the root vole. Therefore, it may be concluded that the history of landscape development affects the genetic structure of hydrophilic species.
