Abstract The population of the Peregrine Falcon (Falco peregrinus) in the Czech Republic recovered from a nearly total extinction during the 1960s and 1980s (0­3 breeding pairs) and the first successful breeding after this interval was confirmed in 1995. The increase of the population size accelerated after 2000 and it is still growing despite the limited amount of suitable natural breeding opportunities. There were 89 known pairs in 2016, 70 of them were proven to breed with altogether at least 121 reared young. Several breeding attempts on historical buildings in city­centres were recorded up to 2002 (in Prague and Pilsen), but this breeding habitat was abandoned later. More and more pairs are nowadays breeding on industrial buildings. The first breeding on a power plant chimney, 300m above the ground was discovered in 2010. Moreover, 16 breeding pairs were found on industrial buildings in 2016 (mainly tall chimneys or cooling towers and power­plant buildings), all of them breeding in nest boxes. The colonization of industrial buildings started in western part of the Czech Republic and continues eastwards every year. Currently, the easternmost colonized building is in Mladá Boleslav. We have no recent tree­breeding pairs and all eight published historical cases are at least doubtful. Most of the observed Peregrines ringed abroad came from Germany, indicating a strong influence of German population on restoration of the population in the Czech Republic. Within these recoveries, some of Peregrines were released in the tree­breeding population restoration project in Germany and Poland, but all these birds bred on rocks.

A preliminary revision of the palynological collection of Professor Blanka Pacltová was carried out considering samples from the middle Cenomanian of the Peruc-Korycany Formation, the basal most member of the Bohemian Cretaceous Basin (the Czech Republic). This collection is mainly composed of slides with palynological residues for light microscope study, which were mounted in the 1960s and 1970s. This work presents an evaluation of the state of preservation of this collection, taking into account the presence of ancient angiosperm pollen types. High percentage of preparations is affected by degradation of glycerine jelly and their remounting is necessary. The present study additionally suggests a methodology for curation of this collection with the objective of long-term preservation.

Abstract. The article describes the development of geodetic surveying and production of geodetic instruments in what is now Czech Republic. The beginnings of development can be found in the 12th–13th centuries during the colonization of the territory and the consolidation of state administration. Significant development peaks occurred in the 14th century during the reign of the Holy Roman Emperor and King of Bohemia Charles IV and then at the turn of the 16th and 17th centuries during the reign of the Holy Roman Emperor Rudolf II. The new direction is related to the development of industry at the end of the 19th century. At that time, several dozen companies in fine mechanics and optics were operating in Prague. The company J. & J. Frič was a world leader in the use of a glass divided circle in 1864. The production of astronomical and geodetic instruments in Czechoslovakia was successful until the end of the 1960s.

A survey on Mycobacterium bovis and M.&nbsp;tuberculosis in humans has been performed in four Central European countries (Croatia, the Czech Republic, Slovak Republic and Slovenia) during the years 1990 to 1999. These countries cover an area of 204 688 km<sup>2</sup> with 22 135 million population. During the period, new cases of tuberculosis were bacteriologically diagnosed in 47 516 patients. M.&nbsp;tuberculosis was detected in 47 461 (99.88%) cases, whereas M.&nbsp;bovis was found only in 55 (0.12%) patients. The rate of infection due to M.&nbsp;bovis in humans did not exceed 0.29% in the study countries. The annual incidence of bacteriological confirmed M.&nbsp;bovis cases did not exceed 0.1 per 100&nbsp;000 inhabitants. In the Czech Republic out of 44 tuberculosis patients due to M.&nbsp;bovis, 32 (72.7%) were older than 61&nbsp;years and originated from rural areas, where they lived during childhood and worked in agricultural occupations. These patients may have suffered a reactivation of persistent (long-standing) M.&nbsp;bovis infection as they got older. Bovine tuberculosis in cattle was eliminated from these countries during the second half of the 1960s (Croatia in 1966, Czech Republic and Slovak Republic &ndash; former Czechoslovakia in 1968, Slovenia in 1973) and the incidence of outbreaks of bovine tuberculosis in cattle were very low, thus the disease in humans was unexpected.

Soil processes over forty years of woodland succession were studied in the abandoned coppices of the Děvín Nature Reserve, in the south-east of the Czech Republic. A total of 113 horizon samples from 34 profiles were taken in the 1960s and 2000s, following identical field and laboratory approaches, to characterize soil texture, contents of carbonates and organic matter, and soil reaction (pH/H 2 O, pH/KCl). Changes in the soil properties were discussed in relation to the gradual development of the mature woodland that replaced the former intensively managed ancient coppice. Four soil types (Luvisols, Regosols, Leptosols and Chernozems) and their horizons were statistically treated to identify distributions/shifts in the measured values from the past to the present. The following results were obtained: (1) The horizontal transport and sedimentation of sandy calcareous particles into the Leptosols topsoil led to increased acidity. (2) In Luvisols, the same was detected for fine clayey particles. This can be explained by the topographical occurrence of the two types — on the upper parts of slopes and under limestone cliffs for the former, and in the flat foothills for the latter soil type. (3) No acidification appeared except for Luvisols, whose luvic horizons E and Bt are, in contrast to the others, poor in calcium carbonate and relatively acidic. A decrease in acidity was recorded in KCl solution, but not in H 2 O. This is interpreted as the consequence of the buffering ability of the soil sorption complex. (4) Slightly improved humification was only detected in the surface horizons of Luvisols and Leptosols. (5) Contrary to expectations no illimerization, i.e. the migration of clay particles from topsoil to subsoil, was revealed.As forty years is apparently too short a time for significant vertical clay migration, it was concluded that i) horizontal migration and the accumulation of substrate particles was of at least the same importance as in situ pedogenetic processes, and ii) soil property dynamics that could be linked with the changed woodland management were proved to act relatively slowly.

The aim of this research was to examine the role of creative and civil initiatives in the transformation of former industrial sites in the Czech Republic, to indicate positive effects of this approach, as well as to identify limitations and offer recommendations. Research is based on two hypotheses. Based on the evidence of monuments left to decay, being demolished or inadequately used by dominantly commercial interests, the first hypothesis is that the complexity of the re-use of heritage requires new, innovative approaches. Second hypothesis is that, since the creative use of former industrial sites can contribute to the city and its residents trough several significant aspects, it should play a more important role in urban planning and heritage management. This paper is a result of the qualitative research based on observation of the phenomenon of the activation of former industrial buildings and establishing the relationship with theoretical concepts.

This article deals with the development of an anti-flood board to protect the interior and exterior of various infrastructures, such a houses, cottages or industrial buildings. It was designed prototypes and assembled numerical simulations. In Central Europe and in particular in the Czech Republic, floods are an integral part of the natural water cycle and cause great loss of life and great property damage. The development of new types of mobile anti-flood boards is very important as the design solution is developed for flood protection with regard to minimizing weight, cost of production, easy manipulation, simplicity and speed of installation.

AbstractThe hypothesis of associating pseudoscorpions with bird nest types was tested on the basis of an analysis of 480 specimens. Eleven pseudoscorpion species were found in 171 nests of 28 different bird species collected in Slovakia, Austria and the Czech Republic. The frequent appearance of Cheiridium museorum, Dactylochelifer latreillii, Chernes hahnii, Dendrochernes cyrneus and Allochernes wideri was confirmed. High proportion and association of Pselaphochernes scorpioides in hoopoe hollow nests with decomposed substrate, D. cyrneus in the Eurasian tree sparrow nest boxes and A. wideri in the nests of the tawny owls, the European scops owls and the European roller was proved. In contrast, C. hahnii and D. latreillii were related to the nest fauna of blackbirds and song thrushes, C. museorum to the nests of white wagtails situated on the ground and on buildings and C. cancroides to the nests in synanthropic habitats. Until present, the occurrence of 22 pseudoscorpion species has been confirmed in the bird nests of Central Europe based on the obtained results and published resources. According to the association to bird nests these pseudoscorpions were classified as (1) nidixenous species — Chthonius fuscimanus, C. tetrachelatus, Mundochthonius styriacus, Neobisium carcinoides, N. crassifemoratum, N. inaequale, N. sylvaticum, Chernes cimicoides, C. similis, C. vicinus, Allochernes powelli, Lamprochernes chyzeri, L. nodosus and Larca lata; and (2) nidiphilous species — C. museorum, C. cancroides, A. wideri, D. cyrneus, D. latreillii, C. hahnii, D. panzeri and P. scorpioides.

Abstract This study offers an overview of the current state in the field of informatics education in the Czech Republic. The new publication of a monograph focusing on field didactics showed that a complex analysis of the current state and future perspectives of developments in informatics education that has not yet been addressed is needed. This paper presents an overview of development in the discipline from the 1960s, defines the main goals of informatics education in the Czech Republic, namely the contents and methods of ICT and computer science education, the need to revise the content areas in official pedagogical documents, teacher education including training of primary teachers and methodology of research in the field of informatics education. The authors of the paper analyse current trends that have impact on informatics education and also refer to the dynamics of computer science education, gradual shift of computer science to lower school levels and introduction of new computer science topics into the area of information and communication technologies. In the conclusion the authors formulate the current problems that informatics education will have to tackle and indicate the possible dangers and perspectives of its future developments. In this article, we distinguish between informatics education as a school subject education and computer science education and ICT education which we understand as parts of this school subject in this context.

Abstract Denmark being a country with only a few suitable steep nesting cliffs has only harboured a small population of Peregrine Falcons (Falco peregrinus) in historic time. In the previous century, the population gradually declined due to persecution, egg and young collection, and pollution. The last breeding attempt in the 20th century occurred in 1972 in southeastern Denmark. No new breeding attempts were recorded in Denmark until 2001 but since then the population has gradually increased – most rapidly since 2012 – to a peak of 24 territorial pairs in 2018; some of them breeding on man-made structures (nest boxes at bridges and power plants). Here we update the information on the reestablishment of the Peregrine Falcon in Den-mark, including origin and dispersal, reproduction, and eggshell thinning.

This paper is devoted to highlighting the stages through which the Czech Republic went on its way to full membership in the European Union. At the beginning of the work, attention is paid to the works of Ukrainian, Russian and Czech scientists analyzed in this context, on which the work is based. Further, an introduction to the historical discourse of events in the political and social spheres in the Czechoslovak Republic after the Second World War is carried out. Attention is drawn to the process of division of the Czech and Slovak Republics in the first half of the 90s. The article tells about the choice by the Czech Republic of the political and social vector for «returning to Europe». Other problems of the Czech Republic on the path of European integration are analyzed, among which one can note the conflict with the Federal Republic of Germany over the forced eviction of the German population from the country in the post-war period, based on the decrees of the President of the Czech Republic Edward Benesh, as well as the solution of this problem through diplomatic means. Attention is also drawn to another problem, which was expressed in the conflict with the government of the Austrian Republic regarding the construction of the Temelin nuclear power plant in the South Bohemian region, in the immediate vicinity of the Austrian borders. The Melk Protocol was analyzed, on the basis of which this conflict was resolved. The general conclusions on this work are summarized, in which the success of the Czech strategy for European and Euro-Atlantic integration is stated. Problems that may arise for Ukraine on the same path are predicted, taking into account the consolidation of the European and Euro-Atlantic vectors of development in the preamble of the Constitution of Ukraine.
