Course content
1. Hydrobiology - characteristics of the discipline (limnology, hydrochemistry, ocean biology) and history in the Czech Republic. Water - physical and chemical properties of water, solar radiation and temperature in the aquatic ecosystem. 2. Characteristics of the water environment, water in the landscape, types of water (surface water, groundwater, standing and flowing water) and their basic characteristics. 3. Basic limnological methods - sampling methods - abiotic and biotic parameters, types of samples and samplers, site survey. 4. Food relationships - energy flow and cycling of elements in aquatic ecosystems, trophic levels (producer, consumer and destructor), trophogenic and tropholytic layers, compensation level, primary and secondary production, herbivore-predator chain, microbial loop. 5. Biogeochemical cycles of elements (oxygen, carbon, nitrogen, phosphorus, iron, sulphur, silicon) and substances (water) in the aquatic environment. 6. Ecological stoichiometry - quality (ratio of major nutrients; C:N:P) and quantity of food resources, effect on primary and secondary production, decomposition rates, species composition of phytoplankton and zooplankton, food webs. Standing waters - abiotic factors - physical (flow, temperature, light, etc.) and chemical (ion composition, dissolved oxygen, nutrients, etc.) characteristics, types of standing waters (lakes, reservoirs, ponds, pools, periodic waters). Zonation of standing waters (epilimnion, hypolimnion, metalimnion, littoral, pelagic, benthic), stratification, classification of standing waters according to organic matter production (oligotrophy, mesotrophy, eutrophy). 8. Standing waters - biotic factors - characteristics of standing water communities, their horizontal and vertical division (plankton, nekton, benthos, neuston, pleuston), main representatives of communities and their characteristics, diurnal vertical migration of organisms, macro vegetation. 9. Flowing waters - abiotic factors - physical (flow, temperature, light, etc.) and chemical (ion composition, dissolved oxygen, nutrients) characteristics, interactions in the river system, rheopelagial, benthic, hyporheic, zonation of rivers (crenon, rhithron, potamon). 10. Flowing waters - biotic factors - characteristics of flowing water communities, zonation (plankton, nekton, benthos, neuston, pleuston, hyporeos), main community representatives and their characteristics, macro vegetation, drift, community changes in longitudinal profile of the stream, fish zones. Morphological and physiological adaptations of organisms to flow. 11. Wetlands - characteristics, importance and function, types of wetlands, plant and animal communities of wetlands. 12. Water pollution - eutrophication, acidification, civilization specific pollutants in waters, aquatic bloom, vegetation coloration, effect of drought on ecosystem. 13. Seasonal dynamics of plankton communities, "clear water", PEG model, Hutchinson's "plankton paradox". 14. Marine hydrobiology - brief description of ecosystem, functions and biology of the seas and oceans. Biological and abiotic factors, zonation, main community representatives and their characteristics.

Learning activities and teaching methods
Self-study (text study, reading, problematic tasks, practical tasks, experiments, research, written assignments), Lecture, Practicum

  • Preparation for exam - 50 hours per semester
  • Preparation for credit - 30 hours per semester
Learning outcomes
The course focuses on the composition (biotic and abiotic components), properties, types and functions of freshwater ecosystems. Marine hydrobiology is dealt with only marginally. The course introduces the relationships of organisms to their environment and the relationships between organisms. The characteristics of standing waters (lakes, reservoirs, ponds, etc.) and flowing waters (streams, rivers) will be discussed, as well as the basic characteristics of typical or ecologically important organisms that inhabit particular habitats. Additional information will be provided on applied limnology focused on water pollution problems (acidification and eutrophication, civilization-specific pollutants in waters, aquatic blooms, etc.). The course will introduce basic hydrobiological methods during practical field exercises. In addition, microscopy of collected samples and identification of organisms present will be done.
Theoretical knowledge and practical skills in the field.
