Sažetak
A total of 45 nematode species was found at the investigated sites of the eulittoral of Lake Sakadaš during 1998: 12 deposit-feeders (bacterial feeders), six epistrate-feeders (algal feeders), eight chewers (predators/omnivorous), and 19 suction-feeders (plant feeders/omnivorous). Chewers were the major group of nematofauna at the eulittoral of Lake Sakadaš – they comprised 68.28% of total nematofauna at submerged site A, 70.13% at site B (at the land-water interface), and 54.16% at emerged site C. The highest relative abundance within the chewers group was found in Brevitobrilus stefanskii, Mononchus aquaticus and Tobrilus gracilis at sites A and B, and B. stefanskii, M. aquaticus and Paramononchus sp. at site C. Suction-feeders were the next important nematofauna group: 19.98% at site A, 23.60% at site B, and 36.97% at the site C, followed by deposit-feeders (5.98–11.78%), whereas epistrate-feeders had the lowest abundance (<2%). Irregularities in the water level and the quantity of food available had the major influence on changes in the distribution of nematode feeding-types.
