The paper analyses and summarizes the results of a national survey of the Northern Lapwing (Vanellus vanellus) in the Czech Republic conducted during the breeding season 2008. Thirty seven observers collected the data within 300 field visits on 151 breeding grounds particularly in southern and eastern Bohemia. A detailed questionnaire was readily filled in by the observers but most of them did not perform all four visits required for each site's survey during the season, as the work effort declined in the period of the third and fourth visits. We suggest simplifying of the questionnaire as well as reduction of the number of visits in future surveys. Arable land (particularly ploughed fields, winter wheat and spring cereal) dominated as nesting habitat of Northern Lapwings at 78% of localities while meadows and pastures were occupied less frequently. Breeding grounds were usually inhabited by one to four pairs while larger colonies, present mostly in ploughed fields, occurred rarely. Presence of marsh patches and/or meadows on the breeding grounds was positively correlated with lapwing abundance. In addition, the results indicate higher hatching success in ploughed fields and at sites with a presence of marsh patches. Agricultural activities were evaluated as the main threatening factor for breeding Northern Lapwings. Regularly occupied breeding grounds were considered as particularly important for lapwing population; these sites are easily detectable early in the breeding season which enables introduction of suitable long-term conservation actions, for example the discussed agri-environmental schemes for Northern Lapwings on arable land.


Introduction: Nutrition greatly affects health, and therefore it is important to identify the factors that determine the choice and composition of the diet. These include food preferences. The aim of the study was to determine whether food preferences differ between both sexes, and how much they are reflected in the consumption. Methods: Both food preferences and consumption frequency for 56 foods and beverages were investigated by use of a questionnaire in a sample of 1665 adolescents aged 15 years in Brno. The differences between the sexes were subsequently analysed. Results: Food preferences differ significantly between the sexes and the preferences of the girls can be described as being significantly healthier. From the top-ten list of the most preferred foods, 6 items are consistent with healthy diet in girls, while only 2 items in boys. Girls significantly more positively perceive raw vegetables, cereal products and fresh fruit, and, conversely, they perceive more negatively lard, hamburgers, processed meats, red meat, offal and carbonated soft drinks. Gender differences in the preferences were statistically significant in 48 % of the items. As for consumption, the gender differences are much smaller than with the preferences. The top-ten of the most consumed items is completely identical for both sexes; it only differs in the order. Also among the least consumed items there is a good concordance between sexes, 8 items from 10 are the same. From the top-ten of the most preferred items, only 1 item (fresh fruit) is among the top-ten of the most consumed foods in boys, and 3 items (fruit, raw vegetables, cheese) in girls. Conclusion: In adolescents, we found significant gender differences in food preferences, where the preferences of girls were much closer to healthy diet. However, the preferences are not readily reflected in consumption. Consumption differs significantly from preferences in so much as that consumption is much closer to a healthy diet. Unlike the preferences, the gender differences in consumption are only very small. The results show that the food choice in both sexes is very modifiable by external factors, which can suppress even the gender differences in food preferences.

The transformational changes after 1989 were reflected in many aspects of the life of our society; they also had a major impact on agricultural production and affected land use. These changes were caused primarily by major social changes including transformation of the economy and agriculture. Slovakia was also affected by globalization. The aim of this article was to characterize the changes in land use and their spatial distribution in relation to the transformation of society after 1989 using the examples of the Dunajská Streda, Levice, Prievidza and Stará L'ubovňa districts. The districts represent the productive agricultural regions of Slovakia. The prevailing processes in land use in the districts as a result of dominant factors will be documented.


Solar energy plays an increasingly important role in the diversified mix of energy sources in Slovakia. By the end of June 2011, almost six hundred photovoltaic power plants had been completed with a total installed capacity of 467 MWp. In this paper, the solar resource potential in Slovakia and economic factors leading to a development of photovoltaic power plant projects at concrete sites are analysed. The conclusion is that the major factors influencing the localization of photovoltaic power plants are the development costs, feed-in tariffs and interest rates valid in the time of starting the project. The installed capacity of the photovoltaic power plants has shown a very weak correlation with the actual solar resource potential. The proposed change in the state support scheme preferring feed-in tariffs set via auctions should press investors to a thorough evaluation of the solar resource potential for all considered power plant sites.

The article deals with the hand, foot and mouth disease. In addition to the issues of common symptoms and management of this disease, it focuses on possible severe neurological complications. Also discussed is the occurrence of large epidemics abroad during which there was involvement of the CNS. In the vast majority of cases, the condition is benign; however, given the risk of associated complications, the goal of current research is to develop a vaccine.


After 1989, a deep transformation of society that influenced all aspects of social life has been taking place in most of the Central and Eastern European countries. Even after two decades, its impacts are still evident in all spheres of society. The aim of this article is to evaluate selected aspects of the post socialist transformation and the influence of these changes on the social and economic marginality of population in old industrial regions in two case studies of the selected districts of Revuca and Roiflava. The partial aim is to compare the processes taking place in these Slovak regions with the same processes that were observed abroad in the 1970's.

The meander of DomaSin represents a noticeable landmark of the River Van valley in the StreCno Gorge through, the Maid Fatra Mountains. A string of remnants of river terraces indicates that the meander was created by the Pleistocene river erosion in a granitic rock mass. Remnants of river terraces were indicated on the basis of geomorphology, fluvial deposits, and geophysical survey. Geophysics also determined the depth of the substratum surface and a thickness of alluvial deposits. The stratigraphic position of 11 Pleistocene river terraces was classified on the basis of their relative elevation.


During a detailed survey of swift nest sites in buildings carried out in the town of Havlíčkův Brod, Czech Republic in the breeding season of 2010, altogether 88 occupied buildings were recorded. In total 334 breeding pairs were found, of which one pair nested outside buildings - in a tree cavity. Concerning protection of the species, one important factor was identifiedamp;:82 percent of the nests were found in rather old buildings, which can be expected to go through extensive repairs, renovations or insulation in the foreseeable future. In the sample, two thirds of the buildings were high-rise buildings with three or more floors. Breeding pair density in the whole study area reached 3.79 pairs per 10 ha. The density in urban parts reached 7.31 pairs per 10 ha. Furthermore, the study revealed preference of swifts for north- and east-oriented nest sites.

We provide an overview of the risks of tick-borne disease transmission between the pregnant or nursing mother and the fetus/child. We focus on Lyme disease, human granulocytic anaplasmosis and tick-borne encephalitis. In Lyme disease, transplacental transmission in humans can not be excluded; there is a lack of information regarding transmission through breast milk. Risks of human granulocytic anaplasmosis in pregnancy are likely, but there is not enough information about them. The latter is valid for risks of transmission during breast feeding. As for tick-borne encephalitis, we do not find evidence in scientific literature for transmission through human breast milk, however there is general awareness of the transmission through production animal milk. Information about the risk of infection in pregnancy has not been reported.


The study evaluates diet composition of the Common Kestrel (Falco tinnunculus) in the town of Bardejov (northeastern Slovakia). In 2009 and 2010, 427 pellets were collected in eight breeding territories of Kestrels. The pellets were collected from below the nests during the summer season. Prey items were analysed using a stereomicroscope. Small rodents, insects and small birds were a major component of the Kestrel's diet. Among interesting prey items, the remnants of bats (Chiroptera) and Common Swifts (Apus apus) were quite common. In total seven mammal species, five bird species, one reptile species, and several insect taxa were identified in the Kestrel's diet.
