River and floodplain restoration of Rohelnice stream with intergation to territorial systems of ecological stability
Komárková, Adéla ; Hubačíková,, Věra (referee) ; Hyánková, Eva (advisor)
This work deals with the state of watercourses, the territorial system of ecological stabi-lity and the possibilities of improvement for a state close to nature. The Rohelnice river basin and the solved watercourses are located in the Olomouc Region in the Morava River Basin. HEM - Hydroecological monitoring is a part of the assessment of the state of watercourses, which is a requirement of the European Water Framework Directive. The work contains the elaboration of a literature search on this topic with a focus on water retention in the landscape and the possibility of improving ecological stability in the basin. The content of the diploma thesis is to evaluate the hydromorphological status of watercourses in the Rohelnice river basin with the selection of sections on watercourses and places in the wider river basin for elements of ecological stability on the basis of zoning plans of affected cities and municipalities and improvement of the overall ecological status in the Rohelnice river basin.

Design of erosion and flood control measures in the cadastral area of Palkovice
Ujházy, Adriana ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This diploma thesis deals with design of soil erosion control measures and flood control measures in the cadastral area of Palkovice. The request for construction came from the village Palkovice. It sits at the foothills of Beskydy with a very sloping terrain. In addition, there are larger soil complexes without any erosion control measures, which leads to degradation and reduction of soil yields. The introduction summarizes desired objectives. Then thesis deals with the description and analysis of the current state of the village and its solution. The solution of technical measures is depicted in the situation and elaborated in more detail. The drawings are enclosed in attachment. The conclusion summarizes the content of the work, achieved goals and benefits.

Diptera in food webs of wetland ecosystems
Pijálková, Helena ; Hadrava, Jiří (advisor) ; Kolář, Vojtěch (referee)
Families of the order Diptera are frequently found in freshwater wetlands, affecting nearly all trophic levels, serving as detritivores, herbivores and predators. Diptera are characterised by an enormous ecological variability of their larval life strategies, which often differ even within individual families. Their adults form an important connection between the aquatic environment of a wetland with its terrestrial surroundings. As a result, adults of various wetland Diptera may serve as pollinators, predators and a prey of other animals including humans. Until now, research of food webs in wetland ecosystems has been focused mainly on a few economically significant groups of Diptera such as mosquitoes, or has been focused on the role of Diptera in transfer of heavy metal from wetlands to other ecosystems. However, overall wetland dipteran diversity still remains understudied. Examining the roles of insects as well as other organisms in food webs is important for example to simulate possible consequences of introduction or extinction of certain species on ecosystems. Further research is therefore necessary to understand how do various dipteran taxa affect other organisms in wetlands as well as their surroundings. Keywords: Diptera, wetlands, ecological webs, detritivory, herbivory, predation

Studie dolní části toku Rakovec v k.ú. Ořešín a návrh opatření k posílení ekologické stability území
Ocásková, Radka
The thesis deals with the passportisation of upper flow stream Rakovec and draft of modifications in the significant landscape element Údolí Rakoveckého potoka. Results of thesis should serve as a basis for planning permission procedure. The first part contains a detailed description of natural conditions and a review of literature focused on the topic. Specifically is focused on legislation regarding land use in significant landscape elements and land returned during restitution to the original owners after 1989. This is followed by a part describing the methods used. The next section summarizes the results arising from legislation and the most important findings from passportization of watercourse are mentioned. Next, several alternative solutions of modifications in the significant landscape element are devised and the selected one is described in details. The thesis is completed by annexes, which contain full passport of watercourse and the drawing part.

The importance and use of wetland plants in the past and present times
KOZÁK, Martin
This paper deals with a research on the importance and use of wetland plants in history and present. The aim of the work is to collect information and critically assess the information on the importance of wetland plants to human society in the past and present including their uses. The review builds on the existing treatment of the topic in the Czech language and extends it with information published in foreign-language scientific and professional literature over the last 20 years and summarizes knowledge especially on wetlands, useful, invasive and endangered wetland plants.
