	Aktivita algologické sekce ČSBS a odborné skupiny biotesty při ČSLS v oblasti toxikologie Sládečková, A. ; Marvan, Petr Detailed record
	Faktory působící na vegetaci příkopů a stok v biosférické rezervaci Třeboňsko Kozlíček, Z. ; Květ, Jan This study evaluates the ecological conditions and their influence on the species composition of the vegetation growing in the ditches and on their banks in the Třeboň Basin Biosphere Reserve, Czech Republic. The results obtained have facilitated the definition of an optimum vegetation management strategy for conservation of the flora of the ditches. Detailed record
	Bottom soils in the rhizospheres of quillworts in the Czech Republic Bohemian Forest Husák, Štěpán The bottom soil from the rhizosphere of both quillwort species (Isoëtes lacustris and I. echinospera) was sampled in the Plešné and Černé lakes in the Bohemian Forest by C. Weilner and his collaborators (1996, 1998) and by M. Böhm (2002), and analysed in the chemical laboratory of the Institute of Botany, Czech Academy of Sciences, Průhonice (see Tab. 1.). The results of chemical analyses from the three years are comparable with smoothly increasing values. Only the potassium concentrations decreased from 116.25 mg.kg-1in 1996 to 5.75 mg.kg-1 in 2002 in Plešné Lake. This decrease can be explained by greater flushing of the sediments from the cirque walls into the stands of Isoëtes echinospora, in 1996. From 2004 to 2006 the bottom soils from Isoëtes stands will be analysed twice per year, with more samples from the Isoëtes stands. Nutrients will also be assessed on the radient between the Isoëtes stands and the shores of both lakes. Detailed record
	Působení břehových porostů na vysoké průtoky vod Pokorný, Jan ; Bodlák, L. ; Lhotský, O. Detailed record
	Algae of Černé Lake in the Bohemian Forest Lukavský, Jaromír Algae and Cyanobacteria of Bohemian Forest are presented, as an important part of plant communities. Streams, bogs, arophytic ans subaerophytic standorts, phytoplankton of lakes and cryoseston are discussed and presented in tables and microphotographs.Bohemian Forest is an important refugium of oligotrophic species and a classic locality for therir study.
