A comprehensive palaeogeographic reconstruction of ice sheets and related proglacial lake systems for the older Saalian glaciation in northern central Europe is presented, which is based on the ...integration of palaeo-ice flow data, till provenance, facies analysis, geomorphology and new luminescence ages of ice-marginal deposits. Three major ice advances with different ice-advance directions and source areas are indicated by palaeo-ice flow directions and till provenance. The first ice advance was characterised by a southwards directed ice flow and a dominance of clasts derived from southern Sweden. The second ice advance was initially characterised by an ice flow towards the southwest. Clasts are mainly derived from southern and central Sweden. The latest stage in the study area (third ice advance) was characterised by ice streaming (Hondsrug ice stream) in the west and a re-advance in the east. Clasts of this stage are mainly derived from eastern Fennoscandia. Numerical ages for the first ice advance are sparse, but may indicate a correlation with MIS 8 or early MIS 6. New pIRIR290 luminescence ages of ice-marginal deposits attributed to the second ice advance range from 175 ± 10 to 156 ± 24 ka and correlate with MIS 6.
The ice sheets repeatedly blocked the main river-drainage pathways and led to the formation of extensive ice-dammed lakes. The formation of proglacial lakes was mainly controlled by ice-damming of river valleys and major bedrock spillways; therefore the lake levels and extends were very similar throughout the repeated ice advances. During deglaciation the lakes commonly increased in size and eventually drained successively towards the west and northwest into the Lower Rhine Embayment and the North Sea. Catastrophic lake-drainage events occurred when large overspill channels were suddenly opened. Ice-streaming at the end of the older Saalian glaciation was probably triggered by major lake-drainage events.

This article analyses the practice of Covid‐related bank regulatory forbearance measures of eight East‐Central European Union member states from the perspective of differentiated integration. In line ...with the integration‐deepening nature of the Single Supervisory Mechanism, our expectation was that countries within the Banking Union (BU) would impose harmonized forbearance measures, while non‐BU members would use more discretional measures. Indeed, the practice of forbearance measures is significantly more harmonized within the BU than outside; however, there were also notable differences in the practice of BU members. For non‐BU member states, our expectation was that countries with the intention of favouring their domestic financial system would ease regulatory requirements more, while those that wanted to place the burden of the pandemic on foreign banks would ease these requirements less. However, the analysis only partially confirmed this expectation.
The Moravian Sahara dune field located in southeastern Czechia represents a unique aeolian system preserving the Late Glacial environment. Until now, the main focus has been concentrated on defining ...its multigenerational development and examining the environmental factors controlling its formation. However, current studies have failed to bring robust chronologies, so environmental and temporal comparisons with the main aeolian phases in Europe could not be made. Here, we present a study combining chronological and environmental interpretations. To do so, four boreholes were drilled to obtain the samples for optically stimulated luminescence, quartz grain morphoscopy and sediment maturity estimation. The results show that the Moravian Sahara dune field developed episodically between the Last Glacial Maximum (LGM) and Younger Dryas, with the peak occurring during the Oldest Dryas. Quartz grain analysis revealed that the phases of wind-blown sand deposition were short and that the dune sediments had three different sources. Furthermore, it appears that the katabatic winds propagated to the study area during the LGM and Late Pleniglacial and were replaced by westerlies since the Oldest Dryas. Finally, the chronology of aeolian activity in the study area shows that Moravian Sahara dune field development was antecedent to the European Sand Belt and shares more similarities with the landforms in the Carpathian Basin located further south.

This volume critically investigates how art historians writing about Central and Eastern Europe in the late nineteenth and early twentieth centuries engaged with periodization. At the heart of much ...of their writing lay the ideological project of nation-building. Hence discourses around periodization – such as the mythicizing of certain periods, the invention of historical continuity and the assertion of national specificity – contributed strongly to identity construction. Central to the book’s approach is a transnational exploration of how the art histories of the region not only interacted with established Western periodizations but also resonated and ‘entangled’ with each other. In their efforts to develop more sympathetic frameworks that refined, ignored or hybridized Western models, they sought to overcome the centre–periphery paradigm which equated distance from the centre with temporal belatedness and artistic backwardness. The book thus demonstrates that the concept of periodization is far from neutral or strictly descriptive, and that its use in art history needs to be reconsidered. Bringing together a broad range of scholars from different European institutions, the volume offers a unique new perspective on Central and Eastern European art historiography. It will be of interest to scholars working in art history, historiography and European studies.
•Załęże Gully is the second known deposit of the chocolate flint in the Kraków-Częstochowa Upland.•New deposit of the chocolate flint is characterized and its past availability evaluated.•The ...petrographic characteristics of the Załęże chocolate flint is presented.
One of the valued chert raw materials used by prehistoric communities in Central and Eastern Europe was chocolate flint. Despite finding artefacts made of it over a wide area, for many years, it was thought to occur only in one location - in the Holy Cross Mountains in Poland. However, the discoveries of recent years have shown that deposits of this raw material also occur in another region of Poland, in the northern part of the Kraków-Częstochowa Upland (KCU). The result of intensive field surveys conducted in this area is the finding of a new outcrop of chocolate flint in Załęże gully (Lesser Poland voivodeship) described in this paper. Based on the results obtained from the radiocarbon and optically stimulated luminescence dating of sediments co-occurring with the flint deposit, a history of the paleogeographic development of this gully has been proposed. Access to the deposit in its present form is limited to modern times, but it was likely accessible elsewhere in this area. Macroscopic and microscopic (using optical and cathodoluminescence microscopy) examinations showed a high similarity with the material of other KCU provenance from the prehistoric mine in Poręba Dzierżna, site 24. In the vicinity of Załęże gully there are many archaeological sites where chocolate flint artefacts were found. Preliminary research suggests that they could have been made from the raw material from the newly discovered outcrop. The new location of chocolate flint occurrence in the KCU region described here is another premise to re-think the existing interpretations related to the extraction, use and distribution of this important chert raw material in prehistoric times in Central and Eastern Europe.
This paper presents data on the distribution of Ventanata dubia in Slovakia. I recorded the species in 145 quadrants of the Central European mapping grid. The majority of these records occurred in ...the Pannonian region, especially in the phytogeographical districts of Podunajská nížina, Burda and Ipeľsko-rimavská brázda Region of southern Slovakia. In the Carpathian region, the species has a scattered to rare distribution pattern and is only found in the area associated with the pre-Carpathian flora, especially in the Štiavnické vrchy Mountains. Ventenata dubia most often occupies dry grassland habitats, but also frequently occurs in human-modified habitats (quarries, unpaved roads through agricultural fields and grasslands, vineyards). It rarely occurs on forest edges or in open forests. The grass was recorded on loessal, saline, quartzite, and limestone soils, but most often on shallow soils with high basalt (volcanic) rock content. At present, it is among the less threatened plant species of the Slovak flora (NT). URL: https://www.upjs.sk/pracoviska/botanicka-zahrada/odborne-aktivity/contents-abstracts/
