Diet structure of Tengmalm’s owl (Aegolius funereus) in the Ore Moutains in 2014-2015: the effect of laying date on the presence of Microtus voles and birds (Aves)
Šimková, Kristýna ; Šťastný, Karel (advisor) ; Kouba, Marek (referee)
Diet structure of Tengmalm s Owl was studied during 2014-2015 in the Loučeň area of the Ore Mountains specifically around the Flájská dam area of 70 km2. This area is strongly affected by emissions. Diet research was conducted with method of pellets analysis which were taken from nest boxes during nesting period. 32 samples were collected during this two years study. Each sample represents content of diet from one nest box during one
nesting period. 6 samples with 259 individuals were from 2014 while 26 samples with 1349 individuals were collected in 2015. In total 1608 individuals were found during 2014-2015, out of them 33 birds (Aves) and 1575 mammals (Mammalia). Diet content was changing during study years, depending on availability of prey. Main part of diet represented mammals (97,9 %), rest of diet was built by birds (2,1 %). Between 2014-2015 mammals were found in following proportion: Apodemus sp. - 52,8 %, Microtus agrestis - 25,1 %, Microtus sp. - 8,0 %, Sorex araneus - 3,0 %, Clethrionomys glareolus - 2,7 %, Microtus arvalis - 2,0 %, Muscardinus avellanarius - 0,6 %, Sorex minutus - 0,5 %, Micromys minutus - 0,1 % and birds in proportion: Turdus philomelos - 0,4 %, Phylloscopus sp. - 0,4 %, Aegolius funereus - 0,2 %, Erithacus rubecula - 0,2 %, Pyrrhula pyrrhula - 0,2 %, Fringilla coelebs - 0,1
%, Parus major - 0,1 %, Anthus trivialis - 0,1 %, Carduelis cannabina - 0,1 %, Ficedula sp. - 0,1 %, Garrulus landarius - 0,1 %, Regulus regulus - 0,1 %, Sylvia atricapilla - 0,1 %, Turdus merula - 0,1 %. Main objective of this study was to evaluate proportion of voles and birds in diet during study reflecting timing of Tengmalm s Owl s nesting. During two years evaluation was proved difference in proportion of birds in diet of Tengmalm s Owl. In 2014 birds represented 15,3% of diet while in 2015 birds were not represented at all. Proportion of voles (Microtus agrestis, Microtus arvalis and Microtus sp.) in Tengmalm s Owl s diet didn t differ significantly during study period.
It was found that in 2014 neither proportion of voles nor birds in Tengmalm s Owl s diet didn t change significantly during nesting period thus the effect of nesting timing on diet content wasn t proved. During 2015 nesting period the proportions of voles in Tengmalm s Owl s diet significantly grew and impact of nesting timing was proved. Birds were not represented in owl s diet at all in this year.

Landscape development in Jachymov
Končelová, Zuzana ; Vaněk, Jindřich (advisor) ; Fedurcová, Alena (referee)
This thesis deals with monitoring developments montane landscapes in the Jáchymov in the Krušné hory (Ore Mountains). In the thesis the attention is given to the history of the min-ing town Jáchymov, founded in the 16th century, which is closely linked to the expansion of mining in the Krušné hory (Ore Mountains). In the thesis I focuse on the events that have marked most of this cultural landscape, in the period from the mid-20th century in connection with the resettlement of the German population followed up with exploitation of uranium ores.
In the thesis I examine all signifiant factors that influenced and shaped this distinctive cultural landscape and analyzes the data of land use from the database LUCC. For more pre-cise and illustrative assessment of changes in the landscape were used not only written docu-ments with historical descriptions, but also a graphical documents. Comparing old photo-graphs primarily from the first half of the 20th century with present situation attention is given to land cover and terrain ganges and changes in built-up area. The thesis comparing the Stable Cadastre and aerial photography with current maps through ArcGIS. There are evaluated local changes related to with the built-up area and the changing terrain. Furthermore, through the manual vectorization, it is been noted land cover in maps of Stable Cadastre and the latest orthophoto. Land cover has been simplified to the three most significant categories: forest area, non-forest area and built-up area. The result is the separate map of the cadastral territory Jáchymov, where the most significant changes are projected, that the increase and decrease of forest and increase of built-up area.
The goal of the thesis is to point out the extremes in the extent of anthropic pressure in this specific landscape. On the one hand, building work camps, massive changes in terrain and remaining tailings, on the other hand, abandoned land and settlement after resettled popula-tion, result of succession and disappearing landscapes microstructure.

Historical water systems in Krušné hory mountains
Jirásek, Jan ; Vaněk, Jindřich (advisor) ; Fedurcová, Alena (referee)
This Bachelor's thesis was focused on mapping the historical water systems, related to mining activities occurring, in the territory of the Czech part of Montanregion Krušné hory - Erzgebirge. These mining water management systems were characterized in the literary part of the work, as well as the historical development of their surroundings. Further it has been described water-lifting equipment powered by water which was fed these with systems. All described systems belonged to the four historical mining district. These were Jáchymov, Horní Blatná, Hřebečná and Přebuz.
Mapping was done in the field using a GPS device. Coordinates which was collected in the course of fieldwork, were exported to the Geographical Information System (GIS) and with that took subsequent processing. The result of the work were map outputs. Maps were made at a scale of 1:10,000.

Analysis of the institutional framework for management of selected ecosystems in the Eastern Ore Mountains
Kratochvíl, Martin ; Louda, Jiří (advisor) ; Osersová, Marta (referee)
The aim of this bachelor thesis is to analyze and calculate the economic value of selected ecosystem services in the Eastern Ore Mountains and then analyze together with quantitative research, which was held simultaneously with the data collection survey. Selected ecosystems are typical for the Eastern Ore Mountains and provide recreational and aesthetic function. Contingent valuation method and method of choice experiment are used to calculate the economic value. The analysis of qualitative research is carried out by institutional analysis. Contingent valuation method is used to determine the willingness to pay for preserving the aesthetic function of mountain meadows in the Eastern Ore Mountains. Quantifying the economic value together with qualitative research may help to define tools for maintenance management of ecosystems that help to protect, maintain or restore ecosystem. Some methods of evaluation of environmental goods and institutional analysis are described in the theoretical section. The practical part is focused on the results of a questionnaire survey with a qualitative interpretation of the results.

Use of GNSS apparatus for designing and documenting mountain bike (MTB)
ŠLECHTOVÁ, Štěpánka
The theme of this work is the use of GNSS apparatus for designing and documenting mountain bike (MTB). Its aim is to propose a new bicycle paths in the Ore Mountains using GNSS equipment. The individual measurements they then process documentation, including directional waves and longitudinal sections of routes. The documentation also includes locating and gathering information on significant points along the route. The result of the work are descriptions of routes and their waveforms generated directional and longitudinal profiles that are processed in digital form with the possibility of their further use. In one of the proposed routes were compared directly measured longitudinal profile with a profile designed by The maps of the Czech Republic 1:25 000
