Selected schools' students' awareness of selected types of nutraceuticals
Homolková, Zuzana ; Váchová, Alena (advisor) ; Hanušová, Jaroslava (referee)
The main topic of this work is food supplements, their legislation and other theory connected with them, the main focus is on plant nutraceuticals, of which are chosen food supplements marketed to support immunity system - echinacea, sea buckthorn and oyster mushroom, food supplements to support psyche - St. John's wort, ginkgo and valerian and dietary supplements to support body fitness - tribulus, garcinia and psyllium. Subsequently, the topic focuses on the marketing of nutraceuticals, its modern ways and the possibilities of increasing the students' awareness in this field through the principles of media education. In the practical part, 112 students aged 15-19 are presented with a lecture presenting the topic and inviting students to raise their interest in the subject. The feedback of the lecture is provided by a questionnaire whose questions correspond to the hypotheses set by the author. KEYWORDS nutraceuticals, media education, marketing, Echinacea, Garcinia, Pleurotus, Hippophae, Gingko, Plantago, Hypericum, Valeriana, Tribulus

Influence of climatic fluctuations in Neogene/on evolution of ecologically diverse plant genus: an example of Hippophae L. (Elaeagnaceae)
Jia, Dongrui ; Bartish, Igor (advisor) ; Štech, Milan (referee) ; Comes, Hans-Peter (referee)
The Neogene geologic processes and climatic changes had tremendous impact on evolution of biota in different regions of Northern Hemisphere (NH). The Qinghai- Tibetan Plateau (QTP) was a central part of these processes. Migrations from the QTP to other temperate regions represent one of the main biogeographic patterns for Northern Hemisphere. However, this 'out-of-QTP' hypothesis has never been tested through a phylogeographic analysis of a widely distributed species and the ages and routs of these migrations are largely not resolved. On the other hand, climate change played an important role in shaping the amount and structure of intraspecific genetic diversity, which provide the main basic substrate for any evolutionary change. Therefore, a detailed understanding of the effects of historic climate alterations on intraspecific genetic diversity can provide valuable insights into the evolutionary consequences of past climate changes and predicting the likely direction of global warming effects on sustainability of extant populations and species. In this thesis, I first studied the phylogeography of Hippophae rhamnoides to test the 'out-of-QTP' hypothesis (Chapter II). Then, I performed phylogenetic, dating and biogeographic analyses of the genus Hippophae (Chapter III). Finally, I studied the...
