The metaphyton-associated invertebrates of the Lake Sakadaš (Kopački rit Nature Park, Croatia)

The growth of metaphyton which consisted of mainly three types of filamentous green algae: Spirogyra sp. Mougeotia sp. and Zygnema sp., developed at the eulittoral zone of Lake Sakadaš (Kopački rit Nature Park, Croatia) in the second half of May 2004, when the water-level start to increased, as well as air and water temperature. These filamentous algae came to the surface and became visible as slimy green masses, which looked distasteful, and indicated eutrophic water which is rich in nutrients. The presence of metaphyton disrupted the physical, chemical and biological conditions of freshwater habitats, so the monitoring of this appearance is very important for the entire ecosystem. The aggregations of filamentous algae are usually short-term, but once the metaphyton establishes, it may function as a macrophytes, thereby increasing surface area for bacterial, algal and invertebrate colonisation. The preliminary analysis included only the qualitative composition of the metaphyton-associated fauna, because of the difficulties in adequate processing metaphyton for quantitative analysis. Hydrophilidae (Coleoptera) larvae and Chironomidae (Diptera) larvae and pupae, Oligochaeta (Stylaria lacustris, Naididae), Nematoda, Cladocera (Daphnia pulex) with high abundance of ephippies, Copepoda (Cyclops sp.), Tardigrada, Ostracoda and Rotatoria were found in metaphyton samples. These organisms find good feeding conditions in metaphytic habitat - a large amount of detrital food particles and algae are trapped by filamentous green algae. And at the same time, the metaphyton represents a refuge from their predators.
