Sažetak
Alien crustaceans and molluscs have heavily invaded Croatian large rivers, but their impact on macroinvertebrate assemblages has been poorly studied. The aim of this study was to assess the biocontamination in the Croatian large rivers, particularly the contribution (number and abundance) of alien crustaceans and molluscs to the total species richness and abundance of macroinvertebrate assemblages. The sampling occurred on two occasions (2015 and 2016/2017) in the main course of four major rivers: the Danube (at 4 sites), Drava (18 sites), Mura (3 sites) and Sava (21 sites). Replicative quantitative (20x0.0625 m2) samples were collected at each site following the AQEM sampling protocol. In total, 22 alien macroinvertebrate species were recorded, with 11 crustacean and six molluscs species. A site- specific biocontamination index (SBCI) was calculated at the family level for all sites from two metrics: Abundance Contamination Index (ACI) and Richness Contamination Index (RCI). The biocontamination at most sites was high (19 sites, 41.3%) and severe (13 sites, 28.3%), and alien macroinvertebrates were not found only at seven most upstream sites in the Drava, Mura and Sava Rivers. The two crustacean (Amphipoda) genera, Chelicorophium and Dikerogammarus, had the highest abundance and proportions among the alien taxa. The biocontamination indices ACI (rs=0.74, p<0.001, n=69) and SBCI-Fam (0.57, p<0.001, n=69) were positively and statistically significantly correlated with densities of the alien crustaceans. The mean number of native taxa (38) at the sites without alien crustaceans was significantly higher than at the sites with alien crustaceans (27). The species Corbicula fluminea and Dreissena polymorpha were the most widespread and abundant invasive molluscs. The alien crustaceans (Amphipoda and Isopoda) were the largest contributor to the biocontamination of the macroinvertebrate assemblages in the Croatian large rivers, and their future spread upstream could cause a decline of native taxa in the upstream reaches of the Drava and Sava rivers.
