Diurnal vertical migrations of zooplankton in a stratified mountain reservoir
Adámek, Radek ; Hořická, Zuzana (advisor) ; Stuchlík, Evžen (referee)
The thesis - a literature review - was aimed at the phenomenon of diurnal vertical migration (DVM) of zooplankton, in relation to particular conditions in the Josefův Důl reservoir in the Jizera Mountains (northern Bohemia, Czech Republic). The area of the Jizera Mts has a very sensitive geology, and thus suffered a strong anthropogenic acidification in the second half of the 20th century. The consequence was a long-term degradation of chemistry and biology of soils and surface waters. The waters in the upper plateau of the mountains were fishless, with a low diversity and biomass of both the phytoplankton and zooplankton. Recovery from acidification is slowest in the deepest reservoir, Josefův Důl. Due to its morphology, thermal stratification, newly re-stocked brook charr population, and invertebrate predators' occurrence, the zooplankton distribution in the vertical profile is expected to be irregular, with DVM. The following diploma project, oriented to seasonal changes and vertical distribution of the zooplankton in the Josefův Důl reservoir, should contribute to long-term data on biological recovery of the reservoirs from acidification, and explain the role of biotic parameters in zooplankton succession.

Fotogrammetric analyses of aerial pictures of mountain landscape and generation of DEM
Hynštová, Marie ; Stuchlík, Evžen (advisor) ; Matějíček, Luboš (referee)
This thesis describes the stereo photogrammetric method used for digitalization of terrain elevation data of choosen area and the applications of digital elevation model (DEM). The main part of the thesis consists of DEM generation methodology, including stereo photogrammetric evaluation of aerial pictures, quality control of evaluating process, DEM creation and revision. DEM was created in software Edras Imagine 8.6. The thesis results in detailed description of DEM creation in the high mountain terrain selected in the High Tatra Mountains. Grid DEM of cell size 1x1 meter is attached. Key words: mountain lakes and catchments, photogrammetry, aerial pictures, DEM

Modeling the recovery of antropogenically acidified mountain waters
Hardekopf, David ; Stuchlík, Evžen (advisor) ; Krám, Pavel (referee) ; Marchetto, Aldo (referee)
11 Abstract In order for an economic system to function and produce goods and services necessary for meeting human needs, it behaves similarly to a living organism. It absorbs materials from the surrounding environment and transforms them into products, but ultimately all the materials are transformed into some kind of waste and emitted back into the environment. This flow of materials is referred to as industrial or socio-economic metabolism (Baccini and Brunner, 1991; Fischer-Kowalski and Haberl, 1993; Ayres and Simonis, 1994). Extraction of resources, consumption of materials and related emissions exert some pressure on the environment. So far, there has been a positive relation between meeting human needs and this pressure. The overall goal of developed countries within their strategies of sustainable development is to break the relation between pressure exerted on the environment and economic growth, which represents meeting of human needs and improvements in the standard of living. This phenomenon is called decoupling (EC, 2002, 2005, 2006; OECD, 2002; UN, 2002). One of the methods for assessing environmental pressure related to extraction and consumption of resources and materials is material flow analysis. In the case of economy- wide material flow analysis (EW-MFA), this method aims at...
