Journal of Biogeography | Year: 2017

Aim: The regional co-occurrence of contrasting bioclimatic elements (warm-temperate, continental, boreal, arctic-alpine) may be shaped by the distribution of their glacial or post-glacial refugia. We tested this hypothesis using pollen proxies in a region where such refugia are expected, but not unequivocally demonstrated. Location: East-Central Europe (Western Carpathians and adjacent regions). Methods: We compiled pollen spectra from 112 sites distributed across various landscapes for six time-periods from the Late Glacial to the present. Compositional patterns were assessed by principal coordinates analyses (PCoA) with a sensitivity analysis based on a bootstrap technique. Site PCoA scores were interpolated geographically and correlated with palaeoclimatic models. Results: Consistently over the last 15,000 years, the first ordination axis sorted samples according to the proportion of deciduous temperate trees, while the second axis consistently followed an altitudinal gradient that coincided with temperature. The principal gradient was more important than the altitudinal gradient except for the Late Glacial and Bronze & Iron Ages, when both gradients were of similar importance. The fine-grained pattern in the present mountain landscape was formed as late as during early modern colonization. Main conclusions: Since the Late Glacial, the landscape has been differentiated into temperate, continental and cold regions. This finding supports the hypothesis that refugia are a key factor for understanding current biogeography in Central Europe. The Late Glacial occurrence of temperate trees is unlikely to be explained only by gradual migrations from southern Europe. Humid but relatively warm mountains hence might have acted as glacial refugia of temperate forest species, while lowlands and leeward basins might have acted as post-glacial refugia of steppe grasslands. The strong contrast between forested (temperate) and more open continental landscapes during the Early Holocene seems to correspond with recent diversity patterns. Our results highlight the relevance of integrating past landscape trajectories into modern biogeographical models. © 2017 John Wiley & Sons Ltd.

Projection systems in display technologies are based on MEMS with moveable elements. Realization of the mechanical interaction is the limiting factor for such complex systems. Application of nanocomposite materials solves the problem of moveable elements production of high accuracy and reliability. Implementation of such materials with enhanced physical-mechanical properties is the only way for industrial development of MEMS containing mechanical moveable elements.

A unique artefact - the fragment of a bow made of yew wood, indicating the hunting activity of prehistoric man - was found within the sediments of the landslide peat bog (at the depth of 330 cm) formed on the Mt. Kamiennik (Polish Flysch Carpathians). The datings of this artefact using 14C method at ca 3790-3380 cal BC indicate its connection with the activity of the Neolithic man, related to the Funnel Beaker Culture. In the sequence of the peat bog deposits formed since the Atlantic Phase, the palaeoclimatic changes of the Middle- and Late Holocene, as well as traces of human impact in these and subsequent periods were recorded and analysed using palynological, macrofossils, lithological methods, and dated with radiocarbon. Palaeoenvironmental changes identified in the peat horizon bearing the artefact were marked by the delivery of minerogenic, "high energy" deposits (with charcoal) to the peat bog, as well as distinct changes of plant communities. These phenomena confirm a significant human impact caused by the Prehistoric man on landslide areas. On the other hand, the study confirms significant importance of climatic condition for human activity and proves that landslide peat bog deposits are very sensitive records of palaeoenvironmental changes. The archaeological artefact essentially supplements the results of our interdisciplinary palaeoenvironmental study. It is one of the rare Neolithic bows found in the area of Europe, till now. © 2009 Elsevier B.V. All rights reserved.

The Hamernia peat bog in the Roztocze region started to develop in the Allerød within the deflation basin divided into two sub-basins by a parabolic dune formed in the Older or the Oldest Dryas. Lithological and palynological analyses as well as radiocarbon dating of samples from three logs cored in different parts of the peat-bog indicate that up to the Subatlantic, when the top of the dune bar was inundated, the evolution of both sub-basins was different in hydrological and sedimentological aspects. Aeolian processes were active in the Younger Dryas, generating delivery of mineral material to both sub-basins. However, the intensiveness of this process was much lower than in earlier cold phases, as indicated by the limited spatial and temporal delivery of this material (restricted mainly to the wind-ward sub-basin). The nature of the next short episode of mineral material delivery to one sub-basin, recorded during the climate cooling at the turn of the Boreal and the Atlantic Phases, is not clear. Local aeolian or slope processes (water erosion accompanied by mass movements) are suspected to be responsible for this episode. The youngest stage of slight but continuous mineral material delivery, caused by aeolian processes, started in the climate cooling at the beginning of the Subatlantic, and was contemporary with the intensification of human activity in this area. The geological history in the Late Vistulian and the Holocene suggests that the last dune-forming stage in this area occurred during the Older Dryas. © 2015 Elsevier Ltd and INQUA.

Northern wetlands ecosystems play an important role in the hydrological balance of neighboring areas, where they act as chemical barriers against anthropogenic and technogenic contaminations. Studied region is well known for quantity of peat deposits and the volume of peat resources. Peat can be considered as a highly informative marker for assessing change in environmental conditions. The study presents the results of the first investigation of peat samples, collected from representative ecosystems of northern wetland territories with low anthropogenic impact.Component and element composition of various peat types were studied in a relation to hydrologic, climate and sampling conditions. It was found out that organic and ash contents are more dependent on the type of the bog, than geographic location. Climatic factors are more important for the formation of bitumen. The degradation degree in peat increases proportionally to content of humates. High content of biogenic and lithogenic elements was observed in transition- and low-moor peat. The content of trace elements in peat samples do not depend on the type of the peat.The structural properties of peat were studied by the light microscopy, AFM and dynamic light scattering. It was determined that the conformation of studied peat samples is characterized by elements of asymmetry. The observed particles in the solutions exist in dynamic equilibrium with separated globular macromolecules. The size of these nanoparticles is comparable with the size of the particles of other biopolymers of similar nature.Swelling of peat in liquid water was studied. The relationship between structural specificities, origin of peat and its maximum degree of swelling was found. The degree of swelling can be used as structural-sensitive parameter in further research. © 2016 Elsevier B.V.

An analysis is made of the magnitudes of the linear trends of daily mean temperature in the city of Minsk for the period from 1966 to 2008. It is found that the largest magnitudes of trends in the annual variation correspond to mid-January as well as to the end of July-August, whereas in May and in November they are poorly pronounced (positive or even negative). The maximum magnitudes of the air temperature trends are in good agreement with maximum warm advection by currents of the Gulf Stream system, while modest warm advection by currents corresponds to weak positive and even negative magnitudes of the temperature trends. Consequently, the magnitude of the temperature trends in the annual variation is modulated by warm advection by currents of the Gulf Stream system which contains a half-yearly component and is determined by natural factors. Therefore, the driving forces of current climate warming cannot be attributed solely to the increase of greenhouse gases in the atmosphere. © 2010.

The paper presents the analysis of organic and mineral sediments filling the depression, which developed over the landslide located at the slope (767–773 m a.s.l.) of Lubań ridge decscending to the Ochotnica river valley in the Polish Flysch Carpathians. The landslide formed in an early stage of the Subatlantic Phase (2490 ± 35 BP). The top of peat is dated at 1360 ± 50 years BP and is covered by 72 cm of clayey silts with some sandy intercalations, which indicate slopewash after deforestation. The pollen of ruderal plants and Cerealia (undiff.) reflect agricultural activity in the surroundings. The fragments of charcoal indicate the age of the forest clearance to the first half of the 17th century. The late forest clearance at the elevated north exposed slopes followed 200–300 years later in relation to the foundation of the village at the valley floor. © 2013, Versita Warsaw and Springer-Verlag Wien.
