My long-term research interest lies in diversity, distribution, ecology, and taxonomy of cyanobacteria. Above all I specialize in elucidating the molecular phylogeny and evolution of cyanobacteria, analysis of their genomes and genetic potential for biosynthesis of toxins and other biologically active compounds. Besides basic research I am also involved in research with potential for practical use in hydrobiological monitoring (identification of cyanobacterial species, ecotoxicology), and further in characterizing novel natural products isolated from cyanobacteria utilizable e.g. in pharmaceutical or agricultural research.

Phycological determination practicum (KBO/128, and KBO/129)
University of South Bohemia, Faculty of Science
Description:
Kurzy KBO/128 a KBO/129 jsou plánovány jako blokové, s 5ti denním pobytem v zajímavé algologické lokalitě. Poslední den pobytu je koncipován jako shrnující přednáška základních typů řas a sinic, které se na lokalitě vyskytovaly. Obsahem cvičení je determinace sinic a řas ve vzorcích z různých biotopů (toky a stojaté vody různých typů, aerofytická stanoviště), které student sám získá. Cílem je podstatně rozšířit determinační schopnosti studentů při práci se vzorky řas a sinic z nejrůznějších typů biotopů.
