Natural Swimming Pool for a Small Municipality
Mrkývka, Michal ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Bachelor thesis deal with natural swimming biotope. In the first part concetrates on the principle of water purification natural swimming pool, a device used for the operation, properties of water, right sort of plant and regulations dictated by the state. In the sekond part presents free selected natural swimming pool in southern Moravia, compares selected indicators in bathing water and source water in natural biotope. At first depots graphic progres sof temperature, transparency and pollution in a particular biotope and then compares individual biotope between them with respect to the notice of the Ministry of Health.

Impact of river system structure on the genetic diversity of reed populations
Fuxová, Gabriela ; Fér, Tomáš (advisor) ; Kubátová, Barbora (referee)
Many plant species are closely related to river biotopes or to biotopes influenced by rivers. River systems create important linear corridors in ecosystems and directly or non-directly influence spatial spread of species in these environments. This offer many questions about species spread in this system. We can answer these questions by using molecular methods. Using 10 microsatellite (SSRs) primers, 202 individuals of Phragmites australis from 60 populations were analysed. Those analyses allowed reveal kinship of individuals, obtain information about spatial spread of populations and about spreading of common reed. Phragmites australis creates both - monoclonal and polyclonal - populations. Dependence of rate of clonality on environment was revealed. Populations from river banks are more monoclonal, populations from pond shores are more polyclonal. Populations are isolated. The highest percentage of variability was explained on among-population level. This is common for anemochoric species. Communication between populations is present, more on shorter distances. Evidence for vegetative spread was found on short distance. Generative spread is much more common. Long-distance spreading is mediated by generative diaspores - seeds. This spreading includes within-river spread, among-river spread and spreading...
