The main component of microfossils in the bottom sediments of Reindeer Lake from Spitsbergen, documenting the almost 8,000-year history of this water body, are algae representing colonies of a very rare species Pediastrum orientale (Skuja) Jankovská et Komárek 1995 with only a very small (lower than 1%) admixture of other green algae species. It ha...

The Lublin chalkland, located in eastern Poland, is one of only a few compact areas in the world where, on the basement of soft carbonate rocks of the Upper Cretaceous age, the so-called chalk karst has developed. This rare type of karst relief is characterized by specific underground drainage, lacking caves but with a rich assemblage of surface fo...

Multi-proxy analyses of two twin sediment cores from Reindeer Lake were performed to reconstruct Holocene environmental conditions in this eastern branch of Bellsund region (Western Spitsbergen). The basal sediment was AMS-dated to 8.4-8.2 ka cal BP. The low thickness of the sediments in the profile, with a good correlation of dates with their dept...

The results of previous researches conducted across the upland territories of Central Europe reflect a considerably close correlation between the settlement by prehistoric agricultural societies and the ranges of the local loess covers. This correspondence – caused mainly by the high utility value of the territories in question, especially the pres...

Ground temperature measurements are crucial for a better understanding of changes in the natural environment, especially in the Arctic. Previous measurement systems provided accurate measurements; however, their most significant disadvantage was the relatively low spatial resolution, including in the vertical profile. The aim of this work was to de...

Purpose. To investigate the genesis and key historical aspects that have led to the popularization of the concept of “definlandization” in scientific literature, as well as the strategic priorities of the formation of the Marshall Plan within the framework of a possible military and economic union between Great Britain, Ukraine, Poland and the Balt...

Spring-fed fen deposits (peat-tufa sequences) from northern Poland were investigated for Holocene environmental reconstruction (climate and hydrology) using multi-proxy analysis (lithofacies, molluscs, pollen, plant macrofossils, geochemistry, and stable oxygen-and carbon-isotopes). The main aims of these studies were: (1) comparison of several sim...

Alkaline spring-fed fens are a rare type of soligeneous wetlands, characterised by an alternating arrangement of layers of peat and calcareous tufa, defined as the peat-tufa rhythmite. They are known, for example, from the strongly undulating young glacial landscapes of Central Europe, where many of them are protected by law. These include sites lo...

The article raises the issue of the nature, intensity and environmental conditions of the settlement processes occurring on the borderline of the loessic Sandomierz Upland and the sandy-clay areas of the Iłża Foothills, between the end of 6th and the beginning of the 4th millennia BC. The results of previously conducted research confirm the high se...

A continuous record of sedimentation in spring-fed fens makes them suitable for detailed palaeoenvironmental studies.

The programme of identification, cataloguing and evaluation of Polish landscapes, part of the implementation of the European Landscape Convention, has caused an increase in interest in physico-geographical regionalisation over recent years. The commonly accepted regionalisation of Poland developed by J. Kondracki (Kondracki & Richling 1994) is suff...

Plant cover is an important element in the management of earthen structures and slopes improving their aesthetic values and limiting their vulnerability to denudation processes. With regard to landslide hazards, an important aspect in the presence of plants is the effect of their root systems on the shear strength of the substrate and, consequently...
