Description:
Lake Śniardwy is the largest among more than 7000 Polish lakes. So far, it has not been a subject of detailed investigations concerning long-term changes in water temperature or ice regime. A considerable change in thermal and ice conditions has been observed in the period 1972–2019. Mean annual water temperature increased by 0.44°C dec–1 on average, and was higher than an increase in air temperature (0.33°C dec–1). In the monthly cycle, the most dynamic changes occurred in April (0.77°C dec–1). In the case of ice cover, it appeared increasingly later (5.3 days dec–1), and disappeared earlier (3.0 days dec–1). The thickness of ice cover also decreased (2.4 cm dec–1). Statistical analysis by means of a Pettitt test showed that the critical moment for the transformations of the thermal and ice regime was the end of the 1980’s. In addition to the obvious relations with air temperature for both characteristics, it was evidenced that the occurrence of ice cover depended on wind speed and snow cover. The recorded changes in the case of Lake Śniardwy are considered unfavourable, and their consequences will affect the course of physical, chemical, and biological processes in the largest lake in Poland.

Description:
To determine the causes of the variation in the seasonal dynamics of Harmonia axyridis (Pallas) in Central Europe, numbers of adults and larvae of this invasive species were recorded on trees (Acer, Betula, Tilia) throughout the growing seasons from 2011 to 2016. Each year beetles were collected every two weeks, using a standardized sweeping method. The seasonal dynamics was expressed as plots of abundance (number of individuals per 100 sweeps) against time (Julian day) and these plots (seasonal profi les) were compared in terms of their size (area under the seasonal profi le curve), range, timing and height of the mode (maximum abundance). Timing and size of seasonal profi les varied among hostplants, years and sites. Abundance of larvae paralleled aphid occurrence and peak abundance of adults followed that of larvae 10 to 20 days later. Population dynamics before and after the peak were determined by dispersal. Adults arrived at sites before the start of aphid population growth and persisted there long after aphid populations collapsed. The abundance of H. axyridis decreased from 2011 to 2013 and then increased, achieving the previous levels recorded in 2015 and 2016. The variation in seasonal profi les revealed that H. axyridis, in terms of its response to environmental conditions, is a plastic species and this fl exibility is an important factor in its invasive success.

František Schmoranz Jr., Islamic architecture, and Central Europe
Language:

Description:
Islámská minulost a současnost se podstatnou topologickou součástí západního obrazu Egypta staly až hluboko ve druhé polovině 19. století. Podíl na tom měl rozvoj vědecké orientalistiky, široká nabídka cestování i sociální a kulturní transformace blízkovýchodního regionu hledajícího svou moderní identitu. Dříve podceňované islámské formy se začaly prosazovat jako prostředky architektonické reprezentace na světových výstavách, kde konkurovaly replikám starověkých památek. Jedním z aktérů tohoto procesu byl rakouský architekt českého původu František (Franz) Schmoranz ml. (1845-1892), podle jehož projektu byl uskutečněn Egyptský pavilon na výstavě ve Vídni v roce 1873. Schmoranz se s islámskou architekturou důkladně seznámil při svých opakovaných mnohaměsíčních pobytech v Káhiře a po návratu působil ve Vídni jako její uznávaný znalec a propagátor. Pro Rakouské muzeum pro umění a průmysl připravil několik expozic islámské architektury a pro světovou výstavu v Paříži 1878 vytvořil kolekci skleněných nádob zdobených orientálními arabeskami. Ačkoliv sám nepublikoval vědecké studie, jako architekt i designér patřil k průkopníkům archeologicky fundovaného orientalismu. Na rozdíl od většiny Evropanů se při studiu islámského umění neomezoval jen na plošnou dekoraci. Schmoranz podstatně rozšiřoval rádius možné recepce Orientu, neboť západní publikum seznamoval s obytnými kvalitami arabského domu a tak uspokojoval potřebu „interiority“, sílící v industriální společnosti 19. století. Příspěvek prohlubuje a zpřesňuje poznatky o životní dráze, tvorbě a záměrech tohoto umělce, a to primárně se zaměřením na problematiku kulturního transferu v souvislosti se světovou výstavou ve Vídni roku 1873. Hledá odpověď na otázku, jak Schmoranzem navržená stavba naplnila očekávání, jež kontakty s Orientem ve střední Evropě probouzely. Současně bylo autorovým přáním touto sondou do recepce islámské hmotné kultury přispět do diskuse o alternativních formách orientalistického myšlení, která zatím byla převážně doménou jazykovědného a literárního bádání. and The Islamic past and present only became a fundamental topological part of the Western image of Egypt in the latter half of the 19th century. This was in part due to the development of Oriental studies as a research discipline, the wide range of travel possibilities, and the social and cultural transformation of the Middle East as it sought its modern identity. Islamic forms that had previously been overlooked began to assert their presence as means of architectural representation at world exhibitions, where they competed with replicas of ancient monuments. One of the actors in this process was the Austrian architect of Czech origin František (Franz) Schmoranz Jr. (1845–1892), who designed the Egyptian pavilion at the 1873 Vienna World’s Fair. Schmoranz became thoroughly acquainted with Islamic architecture during repeated stays lasting several months in Cairo, and upon his return worked in Vienna as a respected expert and promoter. He organised several exhibitions of Islamic architecture for the Austrian Museum of Arts and Industry, and created a collection of glass vessels decorated with oriental arabesques for the Exposition Universelle in Paris in 1878. Though he did not publish any research outcomes, as an architect and designer he was one of the pioneers of archeologically based Orientalism. Unlike most Europeans, his appreciation of Islamic art was not restricted to two-dimensional decoration. Schmoranz significantly expanded the radius of the possible reception of the Orient by introducing the Western public to the residential qualities of the Arab home, thus satisfying the growing need for ‘interiority’ in the industrial society of the 19th century. This article deepens and clarifies our knowledge of the life, work and ambitions of this artist, primarily by focusing on the issue of cultural transfer in connection with the 1873 Vienna World’s Fair. It seeks to answer the question of how the building designed by Schmoranz met the expectations aroused in Central Europe by contact with the Orient. In addition, by means of an investigation into the reception of Islamic material culture, the author wishes to contribute to the discussion of alternative forms of Orientalist thinking, which has up till now been predominantly the domain of linguistic and literary research.

Description:
Based on previously published data, the Czech Republic is regarded an endemic country of the onchocercid nematodes Dirofilaria immitis (Leidy, 1856) and Dirofilaria repens Railliet et Henry, 1911. Nevertheless, while cases of D. repens are commonly reported from dogs in South Moravia, no recent records of D. immitis are available. Therefore, the present study was performed to clarify the occurrence of both species of Dirofilaria Railliet et Henry, 1910. Blood samples of 551 dogs sampled during 2015 and 2016 were analysed microscopically for presence of microfilariae and blood sera were examined by IDEXX SNAP® 4Dx® test (IDEXX, USA). DNA from blood of microscopically positive dogs was extracted and PCR protocol amplifying fragment of cytochrome c oxidase I (COI) gene was performed; PCR products were then sequenced. All dogs from the Bohemian part of the Czech Republic were negative. The prevalence of D. repens in the Moravian region was 5.7 % (27/476). BLAST analyses of obtained sequences confirmed the presence of D. repens (99-100% identical to KX265049). All sampled animals showed a negative result for D. immitis antigen in IDEXX SNAP® 4Dx® test. Our study confirmed the previously reported occurrence of D. repens in South Moravia and revealed its spreading from the epicentre to the north and west. PCR with subsequent sequencing together with negative results for D. immitis antigen in IDEXX SNAP® 4Dx® test revealed only D. repens infection. A previously published autochthonous infection of dogs with D. immitis in South Moravia was not confirmed.
