 Matějček, Tomáš ; Lipský, Zdeněk (advisor) ; Mandák, Bohumil (referee) ; Lacina, Jan (referee)
Resumé The aim of this thesis is to summarize actual results of the field research of invasive neophytes' occurrence in the riverbank vegetation of selected water courses in the Czech Republic. In total approximately 850 km of the riverbank vegetation was mapped using author's own method. The riverbank vegetation was defined according to Novak et al. (1986) as the vegetation belt along a water course with boundaries represented by the water surface and the riverbank edge. The occurence of 22 most important invasive neophytes (sensu Pyšek et al. 2002) was registered using a logarithmical scale (1 = 1-9 specimen, 2 = 10-99 specimen, 3 = 100-999 specimen etc.). Some related species were not recognized (following species were aggregated together: Galinsoga parviflora and G. ciliata; Solidago gigantea and S. canadensis; Parthenocissus quinquefolia a P. inserta and Reynoutria japonica, R. sachalinensis and R. × bohemica). In total, occurence of 17 taxons was registered. The field research was conducted during the summer period of 2006, 2007 or 2008. Development in the years 2006 and 2008 could be compared for 218 segments, that was mapped in both time relations. The occurrence of invasive neophytes (17 taxons) was registered for each of the 500 m long segments (in total 1693 segments was mapped). The number of...
