Studovali jsme výskyt pavouků v půdě, v puklinách v hornině, v kamenitých sutích a v jeskyních České republiky, to jest v podzemních biotopech na hloubkovém gradientu od 10 cm do 100 m. Třináct druhů vykazovalo nějaká morfologická přizpůsobení k životu v podzemí. Druhy s výrazně redukovanýma očima jsme našli jak v hlubokých jeskyních, tak i v povrchových biotopech daleko od krasu. Údaje o morfologii a rozšíření ukazují na to, že troglomorfní druhy musely v průběhu zalednění opakovaně migrovat z jeskyní do povrchových biotopů., Using data from the Czech Republic, we studied the distribution of spiders in soils, crevice systems, scree and caves, i.e. subterranean habitats at depths spanning from 10 cm to 100 m. Thirteen species exhibit morphological adaptations to life in subterranean habitats. Advanced troglomorphic characters occur in deep caves as well as in surface habitats far from karst regions. We hypothesize that troglomorphic populations of spiders in Central Europe repeatedly migrated from caves to subsurface and surface habitats during glaciations., and Vlastimil Růžička.
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
