Course content
Topics: 1. Wetland characteristics, examples of wetlands both abroad and in the Czech Republic. The civilizations dry out the landscape, field crops do not endure flooding. Dried up areas in North America, east Africa, and the Czech Republic. The introduction into solar energy distribution in wetlands and on dried-up surfaces. 2. Physiology of a flooded root. Flooding = lack of oxygen. Adaptation to flooding. Examples of adaptations of various wetland plants. Description of wetland soil, the drainage effect (oxidation, mineralization) 3. Primary production of emergent plants, subemergent plants, and phytoplankton. Dynamics of oxygen concentration and pH, calcium-carbonate balance. Primary production / decomposition ratio. Accumulation of organic substances and their decomposition. Aerobic and anaerobic conditions. 4. Peatbog. Raised bog, transitional peatbog, bog. Oligotrophy. Landscape development since glacial period, an example of paleoecological study. The consequences of peatbog drainage. Revitalization of peatbogs. Humic acids and water quality. Biodiversity in peatbog. Island ecosystems, relicts. Hydrological importance of peatbogs. 5. River meadows and flood-meadows. Biomass production and its use. Watercourse regulation, drainage. River meadow revitalization. Particular examples of retentive ability of river meadows and flood-meadows. Bottomland forests. Production, use. Biodiversity. Flood prevention. Hydrological and climatological function of a bottomland forest. A tree well suplied with water balances temperature differences. A tree as a perfect air-conditioning unit, a description. 6. Ponds, shallow lakes, and their littorals. Development from oligotrophy to hypertrophy. Reed, its growth and withdrawal according to agricultural encroachment. Pond foor chain. Water chemism in both a oligotrophic and eutrophic ponds. Daily thermal stratification, denitrification in anaerobic sediments, phosphor release. An example of botulism occurrence. 7. Examples of actions against blue-green alga, revitalization for restoration of biodiversity, optimization of pond fish stocking and environmental protection interests. Case study - Rod pond from 2014 to 2016. An example of an established routine in a production pond. 8. Case study of lake Naivasha in Kenya. Effect of the legal fishing, waterbirds, and residents on the lake ecosystem. Primary production of the lake, food supply vs. catch. Biodiversity of a prominent locality of Ramsar convention. 9. The role of wetlands in water cycle, retention of nutrients and substances, carbon depositing. Outflow of water and substances from forest, pasture, and wetland. The effect of wetlands on climate in relation to a) greenhouse effect, b) evapotransporation: assessment. Small and large water cycle. Do wetlands waste water? 10. Examples of drainage and particularly successful wetland revitalizations around the world (Florida, Iraq, Natural Sequence Farming/Australia, India, Fingerponds project, Bomosa, deforestation of Mau Forest, and Lake Victoria). 11. Slovak flood control program of founding small wetlands on upper river basin. A documentary. Particular examples. 12. Artificial wetlands, root wastewater treatment plants, Integration of newly founded wetlands into residental units and landscape for nutrient and water recycling, and biodiversity. Green city infrastructure. Means of water retention in cities. How to stop landscape drying out. (Uni Albury Campus, Olympic village in Sydney, Berlin, Zvolen). 13. International conventions on wetland protection (Ramsar convetion, etc.), EU Water Framework Directive. Questions that has arisen during the course. 14. Revision, discussion before test.

Learning activities and teaching methods
Monologic (reading, lecture, briefing), Dialogic (discussion, interview, brainstorming)
Learning outcomes
During several field trips, students will familiarize with a peatbog (Červené Blato), a sandpit (Třeboňská pánev), and shallow oligotrophic sandpits. The effect of pond fish stocking on water quality and biodiverity in relation to the econimic management and with regard to invasive rough fish appearance will be demonstrated on various types of ponds. Water retention ability of a river meadow, a pond (in accordance with the law). There will be excursions to long-term observed basin on the right part of Lipno (the amount of the outflow from a forest, a pasture, and wetland). Practical demonstration of sampling of the sediments, peat, and estimation of biomass production, measurement of primary production and dynamics of oxygen concentration and pH. Assesment of the condition of the pond's food chain.
