Evolution of Retortamonadida (Eukaryota: Excavata: Fornicata)
Smejkalová, Pavla ; Kostka, Martin (referee) ; Čepička, Ivan (advisor)
Retortamonads (Retortamonadida; genera Chilomastix and Retortamonas) are a small group of protists comprising intestinal commensals of both vertebrates and invertebrates and one free-living species of the genus Chilomastix. Molecular phylogenetic studies showed that retortamonads are closely related to diplomonads, Carpediemonas, Dysnectes, Hicanonectes, Kipferlia and two undescribed lineages of free-living Carpediemonas-like organisms, together forming the monophyletic excavate group Fornicata. For a long time Retortamonadida have been assumed to be a monophyletic group. However, first molecular phylogenetic study including sequence data from both Retortamonas and Chilomastix suggested that Retortamonadida are paraphyletic and that diplomonads branch within Retortamonadida. Retortamonads still remain poorly studied protist group and their phylogeny is unclear. We sequenced and analysed SSU rDNA of ten Retortamonas and four Chilomastix SSU rDNA sequences. In addition, we sequenced SSU rDNA of an undescribed enteromonad lineage. The phylogenetic tree of Fornicata was largely unresolved and the phylogenetic position of the genus Chilomastix remained unclear. On the other hand, the genus Retortamonas and diplomonads formed a robust clade. Retortamonas sequences split into three host-specific lineages. The...

Analysis of labor migration in the Czech Republic after admission to EU
Smejkalová, Pavla ; Čabanová, Bohumila (advisor) ; Kotrusová, Miriam (referee)
Diploma thesis "Analysis of labour migration in the Czech Republic after admission to the European union." deals with europe labour migration in the Czech Republic in connection with impacts of Czech Republic admission to the Europe union and simultaneosly the paper deals with labour migration of Czech citizens to the European countries. This research discovers the main processes connected with the integration of the Czech labour market into the structure of the European Union, and to analyse the impacts that this integration has had in the field of work migration. Particular attention is given to the migration of workers from the Czech Republic to the other member states of the EU (specifically Ireland), the target of which is to give evidence that the transition period which is applied to the Czech Republic is not legitimate. There is also a focus on the developments in the employment of Czech people in the Irish labour market and the opinions that Irish people have of the migration of foreign workers to their country (with particular focus on their attitudes towards Czech people). The potential of the migration of Czech workers is analyse in other part of the research. In the last chapter the focus is on the developments in the Czech labour market in its employment of workers from the European Union. The...
