Sažetak
Venice Lagoon sediments have been under long-term and persistent influence of domestic, agricultural and industrial waste. To assess its effect on biodiversity, a one-year study of meio- and nematofauna associations was performed. Sampling sites were characterised by four sediment types: fine sand (VE23), silty sand (VE11), sandy silt (VE5, VE21) and silt (VE9, VE14, VE15, VE17). They were distributed within two zones inside the Lagoon: zone A with heavy industrial pollution (sites VE5, VE9, VE11), zone B affected mainly by urban waste (VE14, VE15, VE17) and zone C just inside the Lido entrance, having open communication with northern Adriatic (VE21, VE23). To discriminate investigated zones, univariate and multivariate statistical methods were used. In all zones, relative abundance of nematodes was more than 90% of total meiofauna. In total 105 nematode species belonging to 73 genera and 23 families were recorded. The highest diversity was recorded in fine sand (20 families, 56 genera, 73 species) and zone C (21 family, 62 genera, 82 species) while the lowest was in silty-sand (12 family, 28 genera, 35 species) and in zone B (16 family, 35 genera, 47 species).Statistically significant differences of Shannon-Wienner diversity index was found between zones B and C. Cluster analysis based on 105 nematoda species discriminate zone C from A and B, as well as fine sand from other sediment types.
