Pollen- and Non Pollen Palynomorphs- Analyses from Svalbard

We analysed fifteen samples of a shallow profile “Sverrefjellet Volcano “, located in the NW part of Svalbard – Bockfjord region (see Fig.1). Frequency of pollen grains, spores and NPP (Non Pollen Palynomorphs) was quite low. Only the local taxa (e.g. Salix and Cyperaceae) produced pollen in greater abundance. The pollen spectrum was considerably varied, although pollen grains and spores of most taxa were present in low abundances. This was due to low pollen and spores productivity of the Arctic flora, which propagates mostly in a vegetative way. To obtain as much information from the profile under study as possible, we analysed the non- pollen palynomorphs as well. We succeeded above all in determination of eggs, buccal tubes and claws of the Tardigrada phylum (Jankovská 1991). The determination has been recently verified by specialists in the field, prof. L. Kaczmarek and dr. M. Roszkowska (in Jankovská et al. 2016). The results of the pollen- and NPP analysis are presented in pollen- and NPP diagram, which represents a picture of the species-poor Arctic flora

THE MIDDLE AGES IN POLLEN-ANALYTICAL RESEARCH ON THE TERRITORY OF THE CZECH REPUBLIC

 An orientation survey of mostly the author’s own results of pollen analyses of medieval sediments from archaeological sites in the Czech Republic is presented. The aim of the several-year-long cooperation with archaeologists was to find out whether, and to what extent, the results of pollen analysis are able to specify more exactly the outcomes of archaeological research. Existing pollen-analytical results confirmed their potential to contribute to interdisciplinary archaeological-archaeobotanical research. From a pollen-analytical perspective it was possible to distinguish early medieval material from high medieval material, particularly in the area of larger medieval towns. Selected finds of palynomorphs (pollen grains, spores and Non-Pollen-Palynomorphs) are mentioned in more detail in the chapters “Botany and pharmacy”, “Hygiene and social situation”, “Problems of the age, function and/or disappearance of some archaeological features and situations” and “Pollen analysis and history”

NOVÉ ODKRYVY KVARTÉRNÍCH SEDIMENTŮ NA STARÉM BRNĚ

During the construction and salvage works in the area of the Staré Brno, two interesting localities were exposed. In the case of the Hybešova locality sediments of the Svratka flood plain were exposed. The presence of these sediments evidences the reach of the innundation of the Svratka River to the area of the Staré Brno. The second locality is called Jircháře. Sedimentation in a small reservoir near the Svratka River can be presumed based on palynology and study of the heavy transparent mineral fraction. Hillsides above this locality were covered by plant and wood vegetation. A marked anthropogenic influence during sedimentation can be observed. The composition of pollen spectra evidences the Late Medieval Age to modern age of the studied sediments. This environment was not directly related to fluvial activity of the Svratka River and was not supplied by its sediments

The European Modern Pollen Database (EMPD) project

Modern pollen samples provide an invaluable research tool for helping to interpret the quaternary fossil pollen record, allowing investigation of the relationship between pollen as the proxy and the environmental parameters such as vegetation, land-use, and climate that the pollen proxy represents. The European Modern Pollen Database (EMPD) is a new initiative within the European Pollen Database (EPD) to establish a publicly accessible repository of modern (surface sample) pollen data. This new database will complement the EPD, which at present holds only fossil sedimentary pollen data. The EMPD is freely available online to the scientific community and currently has information on almost 5,000 pollen samples from throughout the Euro-Siberian and Mediterranean regions, contributed by over 40 individuals and research groups. Here we describe how the EMPD was constructed, the various tables and their fields, problems and errors, quality controls, and continuing efforts to improve the available dat
