This paper introduces a very interesting group of curculionid beetles – weevils of the tribe Cleonini. This tribe includes quite a remarkable large species associated with non-forest habitats, most of which are currently considered endangered. In spite of being very popular among coleopterists, this group of beetles has not been studied in detail within the Czech Republic. and Robert Stejskal, Filip Trnka.

The presented study is devoted to the phenomenon of the counterfeiting activity of Oldřich II of Rožmberk (Rosenberg, 1403-1462), particularly newly discovered forgeries and their interpretations. The motivation to create the forgeries was not ony legitimation of the holding of unjustly seized royal properties, but also the creation of the "image" of a fearless warrior against the Hussite opposition. The author combines diplomatic and historical methods to understand the background of creation of the three groups of forgeries related to the royal castle Zvíkov, the ecclesiastical goods of Svéráz and Zátoň and the trial with the nobleman Jan Smil of Křemže., Přemysl Bar., and Obsahue prameny a odkazy pod čarou
Článek přináší přehled druhů rodu chrpa (Centaurea) rostoucích v České republice. Uvedeny jsou všechny druhy a kříženci a jejich geografické rozšíření a stanovištní nároky, zvláštní důraz je kladen na taxonomické novinky (nově rozpoznané taxony) nebo taxony z území dosud neuváděné., This paper presents an overview of the genus Centaurea in the Czech Republic. All species and hybrids reported from the country are listed, their geographic distribution and habitat requirements are discussed. Taxonomic novelties (recently recognized taxa) and taxa not hitherto reported from the Czech Republic are discussed in detail., and Petr Koutecký.
A conference honored the late Prof. Zdeněk Švestka, one of the great defining personalities of twentieth-century solar physics. His main scientific interest focused on solar flares. During his year at Ondřejov, he became an expert in flare spectra. Later his interests extended into white-light flares, proton flares, and their radio signatures (type II and IV bursts), which were suggestive of shock-acceleration of particles. The conference, organized by the Astronomical Institute, took place on 23-27 June 2014 in Prague. Zdeněk Švestka, born on 30 September 1925 in Prague, passed away on 2 April 2013 in Bunschoten. and Petr Heinzel,Marian Karlický, František Fárník.
