Magisterská práce: Cyanobacteria of wet walls and seeps in Grand Staircase-Escalante National Monument, Utah, USA. Školitel: Prof. Jeffrey R. Johansen, PhD.
Grand Staircase-Escalante National Monument was established as a park by President Clinton in 1997 under authority of the Antiquities Act. This park is one of the largest national parklands set aside in the western United States, yet because of the recentness of its establishment, relatively little biological research has been done in the park. In August 2006 we sampled many of the wet seeps and springs located in the monument and have undertaken study of the algae of these seeps. At present we have about 200 cultures of cyanobacteria isolated from these habitats, and have found at least 50 taxa within these cultures.  The most commonly isolated genus is Leptolyngbya, and we have many species in this problematic character-poor group. Putative new species have been found in the genera Chamaesiphon, Rivularia, Lyngbya, Microchaete, Tapinothrix and Cyanosarcina. Species unambiguously identified include: Pleurocapsa minor, Calothrix parietina, Geitlerinema amphibium, Aphanocapsa musicola, Chroococcus cohaerens, Chroococcus spelaeus, Leptolyngbya subtillissima, Leptolyngbya compacta, and Leptolyngbya carnea.
