Exhibition proposal of wetland biotopes in the arboretum FFWS in Kostelci nad Černými lesy
 Havránková, Zuzana ; Bažant, Václav (advisor) ; Janeček, Vladimír (referee)
This thesis deals with design of a new trees exposure in the arboretum in Kostelec nad Černými lesy, where model of wetland habitats will be created. Emphasis is placed on the supplement autochthonous species especially willow - Salix. A literature review provides information about Arboretum Kostelec nad Černými lesy and compositional principles. It is focused on wetlands, floodplain forest and it is willow communities. Thesis includes the characteristic of the area and it's natural conditions. Inventory of area were made in the practical part. Botanical survey detect current vegetation cover. The area of interest was evaluated from the botanical point of view. Evaluation of the health condition of trees was done to improve the condition of existing vegetation and habitat model layout. Treatment and the existing vegetation felling, was proposed. Map outputs of the research were processed in ArcGIS 10.1. Exposure design was drawn in AutoCAD 2016. List of recommended trees that is based on analysis of Czech and foreign sources was created. Pathway and information system for visitors that use the QR code was designed. The results of this thesis can be applied in practice in Arboretum Kostelec. Model of wetland habitats can be used for research and educational purposes.

Ecological constraints limiting the root-sprouting ability in wetland plant species
 SOSNOVÁ, Monika
Wetland plant species rely largely on vegetative reproduction. Although all types of clonal growth organs are found in wetlands, special adaptations, e.g., turions, fragmentation and budding, are more frequent in true aquatic communities. However, root-sprouting is underrepresented, although it can be beneficial under disturbed conditions. This thesis focuses on ecological constrains potentially hindering root-sprouting in wetlands. This ability was studied in a wetland herb Rorippa palustris in relation to life history, injury timing and carbon economy of a plant. In addition, plant regeneration following submergence and severe disturbance was assessed.
