Biolog z Velké Británie Athol McLachlan testoval v roce 1999 hypotézu, že parazitický roztoč mlžovka ypsilonová (Unionicola ypsilophora) snižuje pářící schopnosti infikovaných pakomárů druhu Paratrichocladius rufiventris. Zdálo se to přirozené. Samci pakomára utvářejí pářící hejna, do kterých vlétají samičky a v nichž si samci konkurují. Velcí ektoparaziti jako mlžovka ypsilonová by tudíž měli snižovat letové a manévrovací schopnosti hostitelů a v důsledku toho jejich schopnost v konkurenci obstát. Experiment však ukázal pravý opak. Množství infikovaných samců v hejnech bylo výrazně nižší (okolo 4 %) než množství infikovaných samců v utvořených párech (okolo 15 %), a tak měli infikovaní samci mnohem větší šanci na spáření než samci neinfikovaní. Co se stalo? and Luděk Berec.
The Residence of Bukovinian and Dalmatian Metropolitans (Ukraine) has been recently added to UNESCO's World Heritage List. The residence represents a masterful synergy of architectural styles built by the renowned Czech architect and philanthrophist Josef Hlávka from 1864 to 1882. The property, an outstanding example of 19th century historicist architecture, also includes a seminary and monastery and is dominated by the domed, cruciform Seminary Church with a garden and park. The complex expresses architectural and cultural influences from the Byzantine period onward and embodies the powerful presence of the Orthodox Church during the reign of the Austro-Hungarian Empire, reflecting its policy of religious tolerance. The former residence is located in the city of Chernivtsi in southwestern Ukraine and is now in use as an University. and Karel Ksandr.
The tradition of International Congresses of Historical Sciences started in 1900. Except during the World War I and World War II, it has been held 21 times so far. Being the most influential academic activity of historical sciences, it enjoys a reputation of the “Olympics of Historical Sciences”. From 23 to 29 August, 2015, the 22nd ICHS was held in Jinan, China. It was the first time for the Congress to be held in Asia. The event, hosted by the International Committee of Historical Sciences, was organized by the Association of Chinese Historians and Shandong University. The Congress included four major themes: “China from Global Perspectives”, “Historicizing Emotions”, “Revolutions in World History: Comparisons and Connections” and “Digital Turn in History”. There were also a series of academic activities such as specialized theme discussions, joint sessions, round tables, evening discussions, and poster session for post- graduate and PhD students etc. Over 2000 historians from all over the world participated in those activities including 15 Czech historians from the Institute of History of the CAS, the Institute of Contemporary History of the CAS, Charles University, University of Pardubice and Palacký University Olomouc. and Jaroslav Pánek.
The 9th annual Science and Technology Week was organized for the public by the Academy of Sciences of the Czech Republic on November 2-8, 2009 and it took place in Brno, České Budějovice, Hradec Králové, Ostrava, Plzeň and Praha. The program included speeches by scientific professionals, presentations of noteworthy experiments, workshops, non-traditional exhibitions, science cafés, and visits to laboratories and academic workplaces. Science and Technology Week is one of the largest science communication efforts which presents the latest scientific achievements and results of current research. and Luděk Svoboda.
