Feasibity study of biofuels sources
Zemach, Vít ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
Technical-economical study of biofuel cultivation is the topic of this diploma thesis. This is a study that includes the technology of growing biomass and its subsequent treatment. Part of the work is an economic and sensitivity analysis, which aims to determine the price of produced biomass. This work focuses on herbal biofuels and their comparison with other types of fuels.

Monitoring invazních a nepůvodních rostlin v povodí řeky Ostravice
Zlá, Kristýna
Spreading of invasive plants on catchment area of the Ostravice river has been monitored from fall 2013 to fall 2014. During the study period, 24 phytocenological images for 6 areas was obtained. The results were extended with data from the Czech National Phytosociological Database and comparative study of the spreading was performed for separate parts of the catchment area. In 211 phytosociological images analyzed in total, I have found 63 non-native species from which 23 was invasive. The most common invasive species was the Himalayan balsam (Impatiens glandulifera), Small balsam (Impatiens parviflora), the knotweed (Reynoutria spp.) and the Solidago canadensis (Solidago canadensis). Number of invasive species increased with decreasing altitude. River flow control and urbanization of nearby areas also had positive effects on the spreading. The study also revealed that occurrence of individual invasive species in coastal areas was different than their occurrence in more distant areas from the river basin.

Monitoring of Invasive Plants in Kopitska Dump (Most)
Čtvrtečka, Tomáš ; Vykouk, Martin (advisor) ; Šmíd, Petr (referee)
This bachelors thesis deals with mapping and finding the way of spreading invasive plant species, particularly Reynoutria japonica, Reynoutria sachalinensis, Reynoutria x japonica, Impatiens glandulifera, Solidago gigantea and Solidago canadensis. Kopistys spoil heap, which is situated in the Most Coal Basin in northern Bohemia near Most, was selected as the area of interest for mapping these invasive neophytes.
The thesis also includes information about selected invasive plant species and brief physical-geographical characteristics of the territory.
In the area of interest were found only individuals of Reynoutria japonica, at 10 sites, as well as individuals Solidago gigantea species in 16 habitats and the last species was Solidago canadensis, which occupied the largest number of sites, a total of 78. It was found way of spreading of the invasion in the territory, distances from each distribution vector was recorded and biotopes, in which invasive plant species were found, was described.

Influence of environmental variables for invasive plants spread in PLA Kokořínsko
Heřmanová, Lucie ; Pěknicová, Jana (advisor) ; Markéta, Markéta (referee)
Bachelor's dissertation is orientated towards issue of presence of invasive plants. In chosen part of PLA Kokořínsko proceeded mapping of current extension of chosen invasive kinds of goldenrod (Solidago) and knotweed (Reynoutria). The goal of this bachelor's dissertation was mapping of affected invasive plants and consecutive evaluation of results, when there was investigated, which biotope affected kinds colonize. As complementary analysis there was investigated preference of type of soil of individual kinds. Most often there was affected S. canadensis, which also covered the biggest area. From final survey resulted which biotopes and ecosystems the invasive plants mostly invade. From the data is also possible to see that invasive weeds colonize most frequently man-made affected habitats and brown soil is preferred kind of soil.
