Natural treeless areas in the Krkonoše mountains
Understanding past landscapes through sedimentary pollen records relies on precise knowledge of modern pollen–vegetation relationships. In mountain environments, however, altitudinal gradients, geomorphological complexity and prevailing air currents affect pollen deposition and make reconstructions of vegetation dynamics harder. This study investigates whether pollen assemblages can effectively differentiate between open habitats above and below …
Dental Care and Education Facing Highly Transmissible Sars-CoV-2 Variants
With the arrival of the highly transmissible Omicron variants (BA.4 and BA.5), dentistry faces another seasonal challenge to preserve the biosafety of dental care and education. With the aim of protecting patients, students, teachers and healthcare professionals, this paper introduces a prospective sustainable biosafety setting for everyday dental care and education. The setting developed by dental clinicians, epidemiologists, and teachers of den…

The prehistory and early history of the Šumava Mountains (Czech Republic) as seen through anthropogenic pollen indicators and charcoal data
In the lower forested mountain ranges of Europe, human impact on nature is usually confined to the written history of the Middle Ages. Our research in the Šumava mountains aims to specify the nature and intensity of human impact on vegetation, especially during agricultural prehistory. We use results from a multidisciplinary study of the unique La Tène archaeological site in the Sklářské Valley (elevation 802 m a.s.l.) and from a pollen and charc…
Wood and Its Impact on Humans and Environment Quality in Health Care Facilities
The paper presents the application of natural materials, especially wood, which are relevant for human well-being in built environments of health, social, and day care facilities. These properties were tested by a complex methodology in a case study in the wooden waiting room at National Oncology Institute in Bratislava. In this space, experimental tests of physiological responses were further executed on 50 volunteers moving in the waiting room …
Population and forest dynamics during the Central European Eneolithic (4500–2000 BC)
Human-induced changes in fire regime and subsequent alteration of the sandstone landscape of Northern Bohemia (Czech Republic)
Multiproxy palaeoecological evidence from a sandstone region in northern Czech Republic was collected to explore the impact of fire disturbances on the decline of the broadleaved forests during the Late Bronze Age (3250–3050 cal. BP). It has been hypothesized that human-accelerated soil leaching affected the nutrient availability in the sandstone area, thus promoting the expansion of oligotrophic-adapted plant communities in the late-Holocene. Li…
Unusual vegetation stability in a lowland pine forest area (Doksy region, Czech Republic)
Although the Holocene is characterized by prominent vegetation changes, some vegetation types can reveal surprising stability. We studied Holocene woodland history in a sandstone pseudokarst area (Doksy region, Northern Bohemia, Czech Republic). Twelve soil profiles collected under native or semi-cultural pine forests were analyzed using anthracological methods. In seven of them, the age of profile bases was established using radiocarbon dating. …
Variation in annual pollen accumulation rates of Fagus along a N–S transect in Europe based on pollen traps
Annual pollen-accumulation rates (PAR) of Fagus (beech) obtained within the framework of the Pollen Monitoring Programme (PMP) were analyzed in pollen traps along a N–S transect from the Baltic Sea to the Black Sea in different European vegetation units. The study regions are situated in the lowlands of northern Poland, the uplands of SE Poland, the Czech Krkonoše Mts, the Czech Šumava Mts, the Swiss Jura Mts, the Swiss Alps, the Bulgarian Rila M…
Annual pollen traps reveal the complexity of climatic control on pollen productivity in Europe and the Caucasus
Annual PAR (pollen accumulation rates; grains cm−2 year−1) were studied with modified Tauber traps situated in ten regions, in Poland (Roztocze), the Czech Republic (two regions in Krkonoše, two in Šumava), Switzerland (4 regions in the Alps), and Georgia (Lagodekhi). The time-series are 10–16 years long, all ending in 2007. We calculated correlations between pollen data and climate. Pollen data are PAR summarized per region (4–7 traps selected p…
Comparing pollen spectra from modified Tauber traps and moss samples
This paper compares pollen spectra derived from modified Tauber traps and moss samples from a selection of woodland types from Bulgaria, the Czech Republic, Georgia, Greece, Poland, Switzerland and Wales. The study examines the representation of individual taxa in the two sampling media and aims to ascertain the duration of pollen deposition captured by a moss. The latter aim was pursued through the calculation of dissimilarity indexes to assess …
Morava River floodplain development during the last millennium, Strážnické Pomoraví, Czech Republic
Floodplain sediments deposited along the lower course of the Morava River (eastern Czech Republic), were studied in the Strážnické Pomoraví region to describe the alluvial history of the river over the last millennium. The sediments exposed in up to 5 m high erosional river banks were analysed using mineral magnetic, geochemical and chemical approaches. The age model of the sedimentary sequences was constructed from radiocarbon dates in associati…
Tentative Correlation of Pollen Records of the Last Interglacial at Grande Pile and Ribains with Marine Isotope Stages
Eemian lake deposits in Grande Pile and Ribains, France, correlate with marine isotope substages (MIS) 5e and 5d as delimited in two pollen-bearing deep-sea cores off Portugal. The Eemian forests in France lasted for approximately 20 millennia, from at least 126,000 to ca. 107,000 yr B.P. Oscillatory climate deteriorations began about 115,000 yr ago. An intense cold spell affected the region approximately 110,000 yr ago.

Předmostí after 110 Years
The Middle and Upper Paleolithic site of Předmosí (Czech Republic) is located at the southern entrance of the Moravian Gate, which is an important communication route in Central Europe. During 110 years of investigation, this site has yielded an immense number of artifacts, paleontological materials, human fossils, and art. Important parts of the archaeological and anthropological material were destroyed in 1945, but the illustrations are publish…
Chronostratigraphie et paléoécologie du Paléolithique supérieur morave d'après les fouilles récentes
L'évolution du Paléolithique supérieur morave commence à la fin du premier Pléniglaciaire würmien (avant 40 000 ans, industnes anciennes du type Bohunice). Dans I ' Interpléniglaciaire suivant, on peut distinguer deux périodes de réchauffement, celle autour de 38 000 ans (industries récentes du type Bohunice, Szélétien) et celle entre 32-25 000 ans (Aurignacien, Pavlovien). On observe un hiatus dans l'occupation pendant le maximum du second Pléni…
