A new Western Palaearctic species of the genus Platyspathius Viereck, 1911, P. picardi sp. nov. is described and illustrated. This species is the most similar to the Afrotropical P. clymene Nixon, 1941 and the Eastern Palaearctic P. hospitus Belokobylskij et Ku, 2001 with which it is compared. A key for determination of the Palaearctic species of Platyspathius is provided.

Dynamic Olfactometry

This paper presents the results of an interlaboratory comparison (ringtest) on olfactometry with 31 participants from four countries in Central Europe. The aim was to give evidence of the performance of dynamic olfactometry on the basis of the European Standard prEN 13725 (Draft) “Determination of odour concentration with dynamic olfactometry”. The test included the analysis of three individual substances (n-butanol, hydrogen sulphide, tetrahydrothiophen) as well as a natural odour mixture (coffee flavour) to compare mean values and the standard deviations of results for the investigated samples. It was confirmed that laboratories working in compliance with the requirements of the new standard achieve a significantly better repeatability and reproducibility than those that are not compliant.

A survey of morphological and phytochemical data characteristic for several taxa of the Achillea millefoliurn group (A. aspleniifolia VENT., A. roseoalba EHREND., A. collina J. BECKER ex REICHENB., A. ceretanica SENNEN, A. setacea W. ET K., A. pratensis SAUKEL & LANGER, A. styriaca SAUKEL ined., A. pannonica SC H E ELE, A. distans W. ET K., A. millefolium s. I., A. millefolium ssp. sudetica OPIZ) and A. crithmifolia W. ET K. is presented. For each taxon a short morphological description and a guide for microscopic analysis is given as well as its sesquiterpene composition including the TLC characteristics. Based on GLC analyses of 1523 single plants collected in Central Europe the sums of sabinene + β-pinene + β-caryophyllene (SUM I), a-pinene + 1,8-cineole (SUM 2), camphene + camphor + borneol (SUM 3), camphene + camphor (SUM 4) and 1,8-cineole + borneol (SUM 5) were found to be highly significant for distinct taxa or groups of taxa.

Abstract Eugeniusz Romer maintained that the notion of Central Europe, introduced at the end of the 19th century by German geographers was of a distinct geopolitical character. The thesis that Poland is situated in a transitional zone between the Western and the Eastern Europe denies Poland the right to an independent political existence. Romer’s opinion was that the location of Poland is characterised by its bridge-like situation between the Baltic and the Black Seas. This location determines the geopolitical identity of Poland as well as its rights to independence. Romer’s arguments, supported by cartographic, demographic and ethnographic research became the basis for the determination of the area and the borders of Poland at the peace conference in Paris (1919 – 1920).

AbstractCercariae of bird schistosomes are traditionally considered to be very similar in their morphological characteristics. In order to solve the problem, we tested some methods which might be suitable for cercarial differentiation. Fourteen isolates of three Trichobilharzia species (T. szidati, T. franki, T. regenti) occurring sympatrically in Central Europe were used. Dimensions of individual cercariae do not represent a useful criterion for identification, because the intraspecific variability exceeds the interspecific one. On the other hand, chaetotaxy appears a promising way for discrimination, although some sensory papillae do not stain sufficiently with silver nitrate. The papillary pattern (i.e. number and relative position of papillae) is specific for all Trichobilharzia species studied by us. Therefore, we compiled an identification key for the three Trichobilharzia species. In addition, we tried to find species-specific surface saccharide epitopes; none of the labeled lectin probes can be used as a speciesspecific marker.

Abstract The objective of the paper was the determination of the circulation conditions of occurrence of strong and very strong frost in Central Europe. A frost day was defined as a day with the minimum temperature lower than 0 °C and maximum temperature higher than 0 °C. Moreover, a division of frost was performed in terms of value of minimum temperature, resulting in the designation of mild frost (up to − 2.0 °C), moderate frost (from − 2.1 to − 4 °C), strong frost (from − 4.1 to − 6 °C) and very strong frost (< − 6 °C). The study was based on data from the years 1966–2015 from the Institute of Meteorology and Water Management—National Research Institute, Deutscher Wetterdienst and National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR). The analysis of baric conditions employed values of pressure at sea level, height of isobaric surface of 500 hPa and air temperature at a level of 850 hPa, as well as their anomalies. The spatial analysis showed that the number of frost days in spring and autumn increased from the west to the east of Central Europe. A decrease in the number of frost days, however, is observed over the prevailing area. Average conditions favouring the occurrence of strong and very strong frost both in spring and autumn were related to higher than average pressure at sea level over the prevailing area of the Euro-Atlantic sector. Such baric conditions caused advections of cool air masses from the northern sector.

Roadside Vegetation

AbstractRoad nets are man-made constructions in the open landscape with a specific vegetation accompaniment in a verge or band along the road or in a divider strip. A determination of six basic vegetation types of bands along roads is possible in Central Europe (tree lines, planting area, forest stand, early successful growth, bushes band, grassy-herbal associations). In the Czech Republic, grassy-herbal communities growing on road verges are mainly formed by perennials, hemicryptophyts, and species with tendency towards pollination by insects and to anemochory and exozoochory. 40% woody and 25% herbaceous species which are non-native for Central Europe form a part of them. Three halophyte species are growing in closed lines along asphalt: Puccinellia distans, Digitaria sanguinalis and Spergularia rubra.Roads and highways should be made and used with respect to the ecological potential of roadside vegetation. However, the road net functioned as a corridor for invasive (planting or spreading) plant species.
