Internal structure of the Balkan refugium using Erinaceus roumanicus as a model organism
Eliášová, Kristýna ; Černá Bolfíková, Barbora (advisor) ; Zemanová, Barbora (referee)
The aim of this work was to describe the spatial distribution of genetic variability of the northern white-breasted hedgehog (E. roumanicus), mainly within the Balkan Peninsula and Central Europe, as these areas are crucial for understanding the effects of Pleistocene climate oscillations on the genetic architecture of the species. Based on this spatial distribution, hypotheses about the possible structuring of the Balkan refugia were formulated. A total of 260 individuals and 9 microsatellite loci were used for the analysis. Using the approach of landscape and population genetics several possible isolated subpopulations within the area surveyed were identified. Unique status was proved for a population originating from Crete, probably influenced by mechanisms of island evolution. Differences from the rest of the range were ascertained also in population from the Czech Republic, located in a secondary contact zone with the E. europeaus. The role of interspecific interactions and possible introgression should be considered in this case. In the area of Romania and the area south of the Balkan Peninsula the highest genetic distances between individuals were identified, probably associated with the occurrence of geographical barriers and the possible presence of glacial subrefugia.

Hedgehogs as the hosts of arthropod-transmitted zoonotic pathogens in Europe
Klimešová, Běla ; Majerová, Karolina (advisor) ; Hönig, Václav (referee)
In Europe, mainly two hedgehog species are distributed - Erinaceus europaeus and E. roumanicus. Both species are suitable reservoir hosts for zoonotic vector-borne pathogens. Hedgehogs have different ectoparasites - ticks, fleas and mosquitoes. Among them, ticks Ixodes ricinus and I. hexagonus are the most important vectors for human pathogens, less importance has the flea species Archaeopsylla erinacei. Variety of viruses and bacteria were detected in hedgehogs: Ťahyňa virus, Tick-borne Encephalitis virus (TBEV), Anaplasma phagocytophilum, Bartonella spp., Borrelia spp. and Neoehrlichia mikurensis. In case of TBEV, hedgehogs are considered to be reservoir hosts. For the rest of detected pathogens, the role of hedgehogs in their life cycle is not clear yet. On the base of published information we can conclude, that the hedgehogs can be source of vector-borne pathogens that cause serious human diseases, especially in urban area where their populations are relatively large. According to the literature review, there are only small differences between the two European hedgehog's species pathogens spectrum and these differences are probably caused by unequal research of the host species. Key words: Erinaceus roumanicus, Erinaceus europaeus, zoonotic diseases, vector - borne diseases, reservoir hosts
