Multifunctional garden ponds and reservoirs
Kraváček, Václav ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The bachelor's thesis deals with the issue of garden ponds and reservoirs with a focus not only on technical design, but also on long-term maintenance of water quality. The main part of the work is devoted to a more detailed description of materials intended for the construction of garden ponds, technical equipment, or the arrangement of individual zones in the pond. Furthermore, the work deals with a detailed description, parameters and character of selected types of reservoirs, such as ponds intended for fish farming, or natural bathing habitats. Last but not least, the work is conceived as a literary search of fundamental knowledge in the field of implementation of garden ponds and their maintenance. The theoretical knowledge is followed by the second part of the work, focused on the design of two variants of the design of a garden pond for a selected investor.

Experimental tasks for teaching photosynthesis of aquatic plants at the elementary school
VAITH, Miroslav
This bachelor's thesis deals with the influence of experimental tasks using a measuring device on the knowledge of pupils in the field of photosynthesis (especially the photosynthesis of aquatic plants) and the refutation of misconceptions related to this topic. In addition to knowledge, the attractiveness of this type of teaching for pupils was also investigated. The knowledge and attractiveness research was conducted in the form of a pretest and posttest. The thesis confirms the positive effect of experimental tasks on the knowledge and attractiveness of the topic of photosynthesis among pupils in elementary school.

Pedological investigation for the design of a natural swimming pool in Olešná u Blanska
Ouředníková, Eliška ; Tomášová, Gabriela (referee) ; Paseka, Stanislav (advisor)
The bachelor thesis is devoted to the problems of pedological investigation including detailed analysis of collected soil samples, such as determination of physical, mechanical and chemical properties of soil. The detailed pedological investigation is followed by another part of the bachelor thesis which deals with the design of bathing ponds, suitable vegetation and animal life in them. The main part of the thesis describes field sampling, laboratory work, evaluation of measurement results and soil classification. The thesis also presents swimming pond zones, materials for construction, examples of fish stocking and flora for the regeneration zone. The thesis includes an evaluation of a practical application, which was carried out in a specific location in the village of Olesna, and a design of the bathing pond is included.

Impact of the type of storage on seed germination of endangered sharp leaved pondweed (Potamogeton acutifolius) and common curled pondweed (Potamogeton crispus)
POSPÍŠILOVÁ, Radana
This work mainly focuses on the issue of seed germination, restoration of turion growth, and their preservation in two Potamogeton species. Particularly speaking about, receding in Czech flora Potamogeton acutifolius (sharp-leaved pondweed) and, in many parts of the word invasive, Potamogeton crispus (curly-leaf pondweed). The introductory chapters contain descriptions of these two species, the germination and turion growth issue of some other temperate zone aquatic plants and turion characteristics. Then the study deals with the experiment itself, including progress of work and the description of individual tests, the results of which are statistically evaluated. Finally, conclusions are drawn from the obtained data.

Určování terestrických forem lakušníků (\kur{Ranunculus} sect. \kur{Batrachium})
VLČKOVÁ, Linda
Ranunculus sect. Batrachium is one of the most intricate groups of aquatic plants. Apart from typical submerged plants, they may grow also terrestrially and determination of the terrestrial forms is very difficult. The aim of this thesis was to establish whether the terrestrial forms of Ranunculus trichophyllus and Ranunculus peltatus differ in their morphology. The species were determined by flow cytometry and the morphological features were measured and analysed.

Long-distance plant dispersal in rivers
Krajníková, Anežka ; Fér, Tomáš (advisor) ; Hroudová, Zdenka (referee)
The aim of this bachelor thesis is to summarise present methods used in the research of dispersal river plants. Generally the dispersal of all kinds of plants which can be dispersed in water corridors, both dispersed in the water column and at the bottom of the channel. The bachelor thesis is a literatural rewiev. The main part of it is focused on direct methods of research of hydrochory and problems which could arise with individual methods. Each method is suitable for different set of circumstances and it is necessary to know in advance what kind of data we want to obtain. The direct methods includes: catching of the seeds directly from the stream - at one time, but repeatedly, or long term catching by using floating traps. Secondly we can use seed mimics or marked diasporas. The second part is focused on other factors which can influence long-distance plant dispersal in rivers. They include the degree to which are rivers regulated and the fluctuation off water level during years. The paper also includes a part which summarise the evidence on long distance dispersal of river plants. Powered by TCPDF (www.tcpdf.org)

Dispersal of clonal aquatic plants
Rydlo, Jan ; Fér, Tomáš (advisor) ; Hroudová, Zdenka (referee)
The aim of this Bc. thesis is to summarize the knowledge on clonal dispersal of aquatic plants and to compare the possibilities and measure of clonal dispersal in selected most-studied species. In the first part of the study, ways of clonal propagation of water plants by various types of vegetative diaspores and various means of transport (by water, animals) are described. Ways and possibilities of dispersal of aquatic clonal plants in various water systems (river systems, stagnant waters) and to various distances are described as well. Finally, anthropogenic effects on clonal dispersal of water plants, which can also play an important role, are discussed. These effects could stay behind many invasive events on the Earth represented by rapid clonal reproduction and dispersal of some species of aquatic macrophytes in their non-native area. The next part of this thesis deals with methods to study the dispersal of aquatic clonal plants and assesses their relevance for various spatial scales. These methods and results of case studies are presented for the most often studied species of water macrophytes. Results of these studies are summarised to demonstrate the real efficiency and distances of clonal dispersal of aquatic plants. Powered by TCPDF (www.tcpdf.org)

Collection of aquatic and wetland plants, Institute of Botany, Academy of Sciences of the Czech Republic, Třeboň
Navrátilová, Jana ; Husák, Štěpán ; Adamec, Lubomír ; Dvořáková, Kateřina
The Collection of Aquatic and Wetland Plants of the Institute of Botany AS CR in Třeboň was founded in 1976 with the aim to enable ex situ studies of threatened plant species. Since that time the Collection has provided plant material for experiments, repatriation of threatened species, taxonomical studies, and botanical illustrations for the compendium Flora of the Czech Republic. It is also used as an educational collection for university students and public. Since 1998, the seeds from the Collection (about 150–200 species each year) have been collected and offered for exchange to other institutions and botanical gardens within the Index Seminum. The Collection of Aquatic and Wetland Plants is located in the Section of Ecology of the Institute of Botany in Třeboň on an area of about 0.04 ha and its current design come from 1997. The Collection includes more than 400 species grown in outdoor containers and in a greenhouse. The overwhelming majority of these species are native to the Czech Republic; the others are mainly from other parts of the northern temperate zone. The Collection of Aquatic and Wetland Plants is the largest collection of living higher aquatic and wetland plants in Europe and one of the largest collections in the world.
