Historical development of zooplankton of the Starolesnianske lake (the High Tatra Mountains, Slovakia) in the context of global changes
Blechová, Magdalena ; Hořická, Zuzana (advisor) ; Sacherová, Veronika (referee)
The aims of the thesis were to document the history of the Cladocera (Crustacea) community structure in the Starolesnianske Lake (the High Tatra Mountains, Slovakia) with regards to environmental changes (e. g., Medieval Warm Period, Little Ice Age, anthropogenic acidification, recovery from acidification), and to analyze in detail the development of zooplankton (Cladocera, Copepoda, Rotifera) during the peaking acidification and recovery from acidification (1978 - 2015). Based on results of both the approaches, the appropriateness of using historical data on zooplankton in Tatra lakes between 1909 - 1913 (Minkiewicz, 1914) as a reference condition for the evaluating biological recovery from acidification should have been assessed. The methods used were paleolimnological analyses of lake sediment (namely subfossil Cladocera), analysis of recent zooplankton, and analyses of lake water chemistry. It was found that in the historical record, relative abundances of Cladocera species significantly changed cca 150 years ago (at the end of the Little Ice Age and, in the main, in the period of anthropogenic acidification). The lake, though, has had a very stable species composition of Cladocera during the last cca 2,000 years, represented by four species: Alona quadrangularis, Alonella excisa, Ceriodaphnia...

Palaeoecological research of mountain lakes in the Carpathian Region: a review
Blechová, Magdalena ; Vondrák, Daniel (advisor) ; Hořická, Zuzana (referee)
The bachelor thesis is a review based on paleoecological research of mountain lakes in the Carpathian mountain region. The aim is to describe lake sediment archives and evaluate current studies and discuss possibilities of future research. This review of the current state of research suggests that there are many challenges and opportunities for future research in the Carpathians. The final part of this thesis is a list of lakes (potential objects of future analysis) with their parameters, including information about paleoecological analysis that have been done. Keywords: Carpathians, Paleoecology, Paleolimnological records, Multi-proxy approach, Mountain lakes.

Motivation of children to participate in sport activities in leisure time
BLECHOVÁ, Markéta
The work deals with general motivation at the beginning. These findings are used in chapter Sport leisure, as well as in sport is necessary to motivate the children during training to achieve maximum results. This chapter also looks at what motivates children to sports activities, and what motives or motives affect them to sports and how the external motives may affect positively (and negatively) the position of an individual sport. The following is an analysis of methods to develop incentives that each lead used in his practice. Finally, the objectives of sport training outline of the basic rules for building sports training hours.

Specific binding of prolactin-releasing peptide analogues in pituitary cells
Maixnerová, Jana ; Špolcová, Andrea ; Matyšková, Resha ; Blechová, Miroslava ; Veselá, Iva ; Železná, Blanka ; Maletínská, Lenka
We report specific binding of 125I-PrRP31 to the following cell lines: GH3 cells (rat – somatotrophs), AtT20 cells (mouse – adenocorticotrophs) and RC-4B/C cells (rat- somatotrophs, lactrophs, adenocortitrophs and gonadotrophs). These results will serve as a basic knowledge for future structure-activity studie sof PrRP.
