Hybridisation dynamics of Typha latifolia a T. angustifolia - differences between Europe and North America
 Mašterová, Helena ; Fér, Tomáš (advisor) ; Hroudová, Zdenka (referee)
Interspecific hybridization is a widespread phenomenon in plants that plays an important role in evolution. It can lead to the origin of new species and is considered to be the one of the processes involved in the creation of invassiveness. In North America there are two species of cattails, original and widely distributed species Typha latifolia (Common Cattail) and probably non-native and less distributed species T. angustifolia (Narrow-leaved Cattail). It is assumed that T. angustifolia was inadvertently introduced by the first Europeans on the east coast of the continent and then spread further west. The spreading was followed by extensive hybridization with T. latifolia, which resulted in production highly invasive hybrid T. ×glauca, which rapidly spread through the vegetative growth and creates a dense monotypic stands that displace the parental and original species. Both species occur in Europe, but it was never investigated, whether the extensive hybridization occurs in Europe.

Plant Rhizodeposition and Rhizosphere Microflora: Their Relationship and Its Consequences in Wetlands
 KUBEŠOVÁ, Jaroslava
Annotation: Plant and microbial relationships in the rhizosphere have been briefly reviewed. The research of tropical wetland ecosystem in northern Belize has been summarized. After that a synthesis of both parts results in the hypothesis of carbon, nitrogen and phosphorus flows between Eleocharis cellulosa, Typha domingensis and their rhizosphere.
