Evolution of Vicia cracca L. - distribution of cytotypes, their genetic variation and growth traits
Eliášová, Anežka ; Münzbergová, Zuzana (advisor) ; Vallejo-Marin, Mario (referee) ; Vašut, Radim Jan (referee)
A lot of the research has been made in the field of plant polyploidy since the discovery of this phenomenon. However, the more we know, the more questions arise. Overall, the most insistent questions remain: How did the polyploids arise and become established? Is it advantageous to be polyploid? We chose a perennial herb Vicia cracca L. to study the causes and consequences of polyploidisation on microevolution of a diploid-tetraploid complex in central European conditions. First, evidence from both flow cytometry and molecular markers (allozymes, DNA sequences, microsatellites) confirmed a hypothesised autopolyploid origin of tetraploids. Based on allozymes, we proved that tetraploids are genetically richer than diploid ancestors. However, we showed that the conclusions depend on statistics used for genetic variation measurements. Nevertheless, tetraploids of V. cracca suffered lesser reduction in seed production after artificial selfing than diploids. We thus infer that they profit from multiple allele dosage, which can mask deleterious alleles. We also corroborated an existence of a central European contact zone of diploids and tetraploids and discovered two other contact zones in south-western and south- eastern Europe. The central European contact zone with several mixed-ploidy populations served us as...

Medial Portrayl of Anezka Hodinova Spurna
Eliášová, Anežka ; Suk, Pavel (advisor) ; Knapík, Jiří (referee)
The presented diploma thesis deals with Anežka Hodinová - Spurná 's media image (1895 - 1963) in the period during WWII and after WWII. The final reference is dated after the year 1989. The aim of this thesis is found how the politician, the MP of the National Assembly and the long-time member of the Communistic Party was presented to the public in representative periodicals. The data for the analysis were gained by studying her personal fund in the National Archive in Prague which contains twenty-eight cardboards and it has not been arranged so far. Then it was used materials from the Archive of the Law-Enforcement Agencies and also materials of Ministry of Interior of the Czech Republic which were made accessible to the public. The gained relevant data were examined by the help of the content-qualitative analysis. The basic research quastion is how Hodinová - Spurná was presented to the public until 1963 and after 1989. The content of this thesis is to introduce briefly Hodinová - Spurná 's life and work and deal with her media image to the general public in time-restricted periods.

Eliášová, Anežka ; Mravcová, Marie (advisor) ; Merhaut, Luboš (referee)
The thesis contains the attempt of analysis and interpretation of chosen stories by Božena Benešová from the thematic, narrative and psychological point of view. It is the contribution to "identification" and evaluation of original poetics of meanwhile a little investigated representative of realistic considered literary psychologism of the first half of the twentieth century. Chosen stories are: Surface, Little Mice and Questions without the Answer.
