WWTP´s in mountains areas
Frank, Ivo ; Plotěný, Karel (referee) ; Hlavínek, Petr (advisor)
Objectives of this master's thesis are to process review of technologies used to treat wastewater in alpine environment in Slovakia and in foreign countries. Thesis also includes mapping of situation of chosen alpine cottages in High Tatras. For cottages with unsuitable technology will be suggested more suitable solution.
Diversity of floral functional traits and its seasonal changes in alpine environment
Plachtová, Kateřina ; Sklenář, Petr (advisor) ; Janeček, Štěpán (referee)
Floral functional traits characterize flowers and mediate contact between entomogamous flowers and their pollinators. Their form depends on many biotic and abiotic factors. The floral functional traits tend to be similar in high altitudes. However, the overall diversity of the floral functional traits does not vary significantly between altitudes. On the other hand, how temporal diversity of the floral functional traits varies during the flowering season was not studied yet. And this is the focus of this thesis. The aim of this study is to examine the hypothesis, whether the diversity of the floral functional traits changes in plant communities of alpine and montane meadows during the flowering season and also between them. The alpine and montane meadows are located in the area of Luční hora in the Krkonoše National Park. Morphological and spectral characteristics of the flowers were measured on both meadows. Abundance of flowering species and their flowers were measured every three weeks during five periods of the season. Diversity of the floral functional traits was obtained, for both meadows and all the measured periods of season, by weighting the floral functional traits with the species abundances. Using multivariate analysis, differences of temporal and altitudinal diversity were studied....
The role of phenotypic plasticity in parallel altitudinal differentiation in Arabidopsis arenosa
Požárová, Doubravka ; Kolář, Filip (advisor) ; Klimeš, Adam (referee)
Plants adjust to challenging environments by genetically fixed changes and phenotypically plastic response. Alpine environments pose multiple challenges to plant life including cold, high irradiance and short vegetative period. To survive such specific conditions, plants often significantly alter their morphology. In my thesis I studied to which extent specific traits of alpine ecotypes repeatedly appear among independently formed alpine populations and to which extent these changes represent fixed genotypic differentiation vs phenotypic plasticity. To address these questions I performed an experiment in which Arabidopsis arenosa plants from sixteen populations belonging to two ecotypes (alpine and foothill) were grown in conditions resembling alpine vs foothill conditions. Specifically, I modified levels of irradiance and temperature and complemented alpine-like and foothill-like treatment by additional two extreme treatments to reach full-factorial design. I used discriminant and classificatory analysis to examine the overall morphological differentiation characterised by set of twenty measured traits. Then I examined variation in each trait by statistical Bayesian model that I designed for this purpose. I found out that although ecotypes are predominantly differentiated by fixed morphological...
