Diatoms (Bacillariophyta) are one of the most diversified group of algae. They occur worldwide in both aquatic and terrestrial habitats. Diatoms are important in global biogeochemical cycles because they contributed up to 20% to carbon fixation and up to 50% to oxygen production. A unique feature of diatoms is formation of glass shells, which is produced by silicification of their cell walls. Morphologically variable diatom shells (frustules) are frequently used in monitoring of recent and past environmental conditions. The course Diatomology will focus on basic knowledge of diatom taxonomy, morphology, and ecology in practical way. Lab work will focus on light microscope observations of living and cleaned diatom samples. We will use digital photography systems to document the groups. One field trips outside the lab will be expected. The course would be useful to undergraduates and graduate students interested in protistology, algology, aquatic ecology and diversity of photosynthetic organisms as well as biomonitoring.
The course will be held in blocks: 21.3. (approximately one hour information session), 28.3., 4.4. and 11.4. (9 - 15 h) at B13 (building Benatska 2). Last update: Kulichová Jana, doc. Mgr., Ph.D. (20.01.2025)

Students should be present on all 3 blogs and prepare protocols accordingly. Important information: "The course can only be evaluated with CREDIT POINTS, no MARKS! Please, note, that there is no percentage evaluation!" Last update: Kopalová Kateřina, Mgr., Ph.D. (21.11.2024)

A plan of the course: - diatom classification - identification terminology - diversity of diatom genera - ecology of diatoms - scientific topics associated with diatom research
- identification of diatoms using both light end electron microscopy - assessment of intra- and interspecific variability in morphology using microphotographs - recognition of the habitat origin (aquatic/terrestrial; marine/freshwater; planktic/benthic) - evaluation of water-quality (trophy indices, acidity, indicator taxa) Last update: Kulichová Jana, doc.
