The Importance of Dinoflagellates in Marine Ecosystems
 Suldovská, Eva ; Říhová, Dagmar (advisor) ; Soldán, Zdeněk (referee)
This bachelor thesis deals with the unicellular organisms dinoflagellates (Dinoflagellata), which belong to the SAR supergroup, specifically in the Alveolata infrakingdom. They are widespread in marine and freshwater ecosystems around the world. Dinoflagellates are a highly heterogeneous group of organisms with an important role as primary producers in aquatic ecosystems. The thesis focuses especially on marine dinoflagellates and their importance for marine ecosystems. Some species of dinoflagellates have the ability to bioluminescence, which they use in their life strategy. Dinoflagellates have an ability to form vital symbiotic relationships, for example with corals. If the symbiosis between a coral and its dinoflagellate is disturbed, it can cause the global phenomenon coral bleaching. Dinoflagellates are associated with many other dangerous global phenomena. The red tides phenomenon is caused by the overgrowth of dinoflagellates and they can also cause the severe poisoning of organisms through excreted toxins. The bachelor thesis also focuses on methods that could help reduce the consequences of these global dinoflagellate-caused phenomena. The main aim of this bachelor thesis was to create a literature review dealing with the characteristics of dinoflagellates and their ecological...
