The paper describes a new profile of lake-bog sediments at the Srebrna site in central Poland. Palynological analysis of deposits confirmed their Eemian Interglacial to Early Vistulian age. Based on palynological data the authors made a reconstruction of climate and vegetation changes from the middle Eemian Interglacial to the beginning of the Early Vistulian.

This paper presents the results of fossil Cladocera analysis using material obtained from seven palaeolakes of the Eemian interglacial located in Poland. The main aim of this study was to investigate the state of preservation and diversity of species in the Eemian Cladocera. The studied Eemian lakes were formed at the end of the Wartanian Glaciation in tunnel and kettle holes. They had preserved a continuous record of environmental changes throughout the Eemian interglacial, until the Vistulian Glaciation. Cladocera fossils found in Eemian sediments were thinner and had a more damaged structure than fossils from the Holocene. Low degree of fossil preservation forced to develop an alternative method for preparation of the fossils for the microscopic analysis. Cladocera species found in the examined palaeolakes corresponded to the present-day species inhabiting Poland and Central and Northern Europe. The changes in species composition resulting from climate changes corresponded to the current geographic distribution of Cladocera. Despite the poor condition of the obtained fossil remains, the results showed that cladoceran fossils in sedtments of palaeolakes may be used in the reconstruction of environmental conditions from the period preceding the last glaciation.

The Białowice site is situated in the north-west of the Nowa Sól Depression which is part of the Central Poland Lowlands. Palynological analysis shows that lake and swamp accumulations took place in the Early Vistulian. Two warm interstadial-rank oscillations (Brörup and Odderade) and a stadial (Rederstall) have been distinguished during the Early Vistulian. The sequence of changes at Białowice is similar to the sequences in profiles from other parts of Poland and Western Europe. Until now, in that region of Poland the vegetation succession of the Brörup and Odderade had remained unknown. The lithology of the profile at Białowice shows rapid changes of sedimentation which have been observed in the younger part of the Brörup and at the Brörup/Rederstall transition. Geological and palynological data suggests that the maximum limit of the Vistulian Glaciation to the south of the Żary Hills.

Pollen assemblages in peat and silt deposits from a core drilled at Gutów, Wielkopolska Lowland, have been analysed, enabling characterization of the development of vegetation and of palaeoenviromental change. The pollen analysis shows phases with forest and open vegetation communities alternating in response to climate changes. The age of the succession can be related to the stadials and interstadials of the Early Vistulian.

The stratigraphy and palaeogeography of Quaternary deposits under lying the Oleoenica Plain were investigated during mapping of the Syców sheet of the De tailed Geo logical Map of Poland on the scale of 1:50 000. The Oleoenica Plain is part of the southern foreland of the Trzebnica Ridge, the latter representing a frontal moraine of the South and Middle Polish Glaciations. Neopleistocene deposits found at the Dziadowa Kłoda site were analyzed for their pollen content. These lacus trine to swamp deposits represent a continuous and undisturbed sequence spanning the Eemian Interglacial to Brörup Interstadial interval. The Early Vistulian deposits have been the subject of detailed palynological investigations. The reconstructed pattern of vegetation changes has allowed a precise determination of the upper boundary of the last interglacial as well as the recognition of stadial-interstadial horizons. Three climatic oscillations have been noted, corresponding to the Herning and Rederstallstadials and the Brörup Interstadial. In the climatic optimum of the interstadial, dense boreal pine-birch forests accompanied by a minor admixture of alder and spruce were predominant. Cold stadials were dominated by open vegetation with tundra and steppe elements.The pollen sequence from Dziadowa Kłoda is the first site on the Silesian Lowland that shows the first fully developed Early Vistulian warm oscillation that correlates with the Brörup Interstadial. A distinctive feature of this site is a long, continuous pollen sequence of the Eemian passing into deposits of the Vistulian Glaciation in the same profile.

The Łanięta site with fossil lake deposits is situated just in front of the maximum extent of Vistulian Glaciation ice. Palynological analysis shows that lake accumulation lasted through the Eemian Interglacial and almost the whole Early Vistulian, the longest record of this time interval in this part of Poland. Two warm interstadial-rank oscillations (Brörup and Odderade) and two stadials have been distinguished during the Early Vistulian. The older of these is correlated with the Herning Stadial while younger one equates with the Rederstal Stadial of the German succession.

Alluvial and oxbow deposits preserved 18 m above the Skawa River valley floor are related to the Early Vistulian. Pollen analysis of the two mainly terrestrial profiles revealed a boreal forest succession. The age of the deposits is discussed.
