Nárvh ekologické sítě v katastrálním území obce Olešínky
Odehnalová, Marcela
This work deals with the definition of biotope in the cadastral territory Olešínky. The cadastral area Olešínky habitats have been identified and determine the degree of ecological stability. After the establishment of habitats is divided to physiotypes. In these bio-types were determined by plants and animals species. Species were included to the habitats according their occurrence with observation. The observation was carried out during one year. The aim of the work was to identify existing major segments with a predominance of natural landscapes and natural communities with higher biodiversity. The next task was to design a bio-centers and corridors on this area. As a result, it was found according to the degree of ecological stability in the territory under study is 0.1% of the major sites, 33.9% partially major sites and 66% of minor sites.

Stanovení biologicky aktivních substancí v rostlinném materiálu
Dobeš, Jiří
This thesis is focused on the determination of antioxidants and antioxidant activity. In the first work DMPD method was optimized to determine the antioxidant activity of antioxidants standards and the reaction was monitored depending on the time, temperature and concentration. In the second work automated determination of antioxidant activity of phenolic compounds standards rutin, quercitrine and standards of phenolic acids gallic acid and ferulic acid was tested using five different methods used in the determination of antioxidant activity using an automated pipetting machines and spectrophotometer. In the third work phenolic profile and total antioxidant capacity (TAC) was determined in apricot cultivars with methods high frequency liquid chromatography with tandem electrochemical and UV spectrometric detection and these two methods were compared. In the fourth work electrochemical methods used for the determination of phenolic compounds were described. In the fifth work oxidative stress induced by silver ions in the Staphylococcus aureus bacterial culture was investigated using spectrophotometric and electrochemical methods.
Semantic Shift in Plant Names
DOSKOČILOVÁ, Iveta
The aim of the present work is to identify and list English plant names coined by semantic shift, namely by metaphor, metonymy or synecdoche, and to carry out a detailed categorisation of individual semantic categories based on different tendencies within them and interpretation of the results. The theoretical part of my work focuses on different approaches to semantic shift and its categories. It is followed by the practical part which deals individually with metaphor, metonymy and synecdoche, their sub-categorisations and then with overlapping of the above-mentioned categories. The work is concluded with several case-studies of interesting instances of semantically shifted plant names and with the summary and conclusion of the results of my study.
Suggestions of science field trips to selected locations around Horažďovicce with using in teaching natural history at the 2nd primary school
ZÁBRANSKÁ, Věra
The main aim of this thesis is the suggestion of excursions into certain places in the region of Horažďovice for pupils from 6th to 9th grade at elementary school. The thesis is divided into the theoretical part and the part focused on preparation of these excursions. The theoretical part is concerned with plan and tuitional methods which are useful for preparation änd realization of the excursions. The second part is dedicated to the description of natural environment of the region of Horažďovice and particular localities. They consist of protected areas and nature reserves - Prácheň, Pučanka and Svaté Pole. Excursions are focused on processing of knowledge gained during natural science lessons and these localities were chosen thanks their various kinds of animals and plants.
Ecology and conservation of invertebrates at anthropogenic sites
TROPEK, Robert
This thesis deals with communities of arthropods (and partly also vascular plants) colonising diverse anthropogenic sites. It reveals a conservation potential of these sites and focus on ecological requirements of both whole communities and individual species generalising these findings for usage in restoration of these sites.
Monitoring pěstebních ploch‚ přenos a detekce transgenů geneticky modifikované řepky olejky
Výzkumný ústav pícninářský, Troubsko ; Pernová, Eva ; Vymyslický, Tomáš ; Badalíková, Barbora ; Hrubý, Jan ; Hájková, Petra
Cílem projektu je zjišťovat přítomnost geneticky modifikované řepky olejky na plochách, kde byla v minulých letech pokusně pěstována ( přežívání semen a vzcházení výdrolu), a zjišťování případného přenosu transgenu na příbuzné plevely. Vlastní monitoring zahrnoval sběr vzorků z příslušných lokalit, uchovávání vzorků, jejich analýzy na přítomnost genu bar a vyhodnocení analýz. Komentář k materiálu a metodice, výsledky monitoringu.
