Factor(s) influencing meiofauna and nematodes of the submerged eulittoral zone of Lake Sakadaš (Nature Reserve Kopački rit, Croatia)
The benthic fauna samples were taken from a sandy submerged eulittoral site at Lake Sakadaš, Kopački rit (Croatia) from November 1997 to December 1998. The meiofauna and freshwater nematode abundance pattern and diversity were analysed with regard to water-level fluctuation and seasonal temperature change. The meiofauna abundance and diversity showed temporal variations. The nematode relative abundance varied from 4 up to 90% of total meiofauna abundance, totally absent in August. In total, 26 nematode species were recorded. The nematode species composition depends on the water-level fluctuation. The water level above 200 cm drasticaly changed the species composition. Brevitobrilus stefanskii, Tobrilus gracilis and Mononchus aquaticus chewers were dominant species during the low and the middle water level, and suction feeders were dominant during the high water-level. The temperature and water-level fluctuation determined the diversity and abundance of benthic fauna in the submerged eulittoral zone of Lake Sakadaš.
