Course content

The basic division - types of water - running, stagnant . Characteristics of water as the environment for aquatic invertebrates. Basic abiotic parameters - temperature, density and viscosity of water, substrate, water flow, water level fluctuations, light, oxygen, and other chemical properties. Spatial homogeneity and continuity in the aquatic environment. Biological influence the aquatic environment, cycles of biogenic elements (oxygen, nitrogen, carbon, ...), rock-forming activity (corals ). The importance of knowledge of biology and accurate determination of aquatic animals for ecological studies. The origin of aquatic organisms - primary and secondary hydrobionti. Morphological and physiological adaptation hydrobiontů. The movement of aquatic organisms - general principles, the properties of water with respect to the movement of organisms (density, viscosity, temperature, movement of water). Respiration of aquatic organisms - general principles. Effect of an organism - photosynthesis vs . respiration - influence the oxygen concentration. The diet of aquatic organisms - general principles. Food sources in the water and the food chain (network). Reproduction and ontogenetic development. Asexual reproduction (asexual), sexual reproduction (sexual), parthenogenesis, heterogonie (diversity), neoteny, the resting stage. In the exercises are living objects demonstrated the characteristic manifestations of aquatic invertebrates.

Water environment and ecology of water organisms
Students gain important information about the biology of aquatic invertebrates. They will acquire knowledge, especially of their ecology and function in aquatic ecosystems. They will gain a comprehensive overview of species in the Czech Republic. For each group will know the specific biological manifestations species (movement, respiration, nutrition, reproduction) and especially important representatives of European wildlife protozoans and aquatic invertebrates: "Porifera", Turbellaria, Nemertea, Cnidaria, Gastrotricha, Rotifera, Ectoprocta (= Bryozoa), Tardigrada, Nematoda, Nematomorpha, Annelida, Mollusca, "Crustacea", Aranea, Hydrachnelae, Collembola, Ephemeroptera, Odonata, Plecoptera, Heteroptera, Megaloptera, Trichoptera, Lepidoptera, Neuroptera, Hymenoptera, Diptera, Coleoptera.
