The aim of the inventory was to fill the gaps in the distribution knowledge and to identify symptoms of anthropogenic influence on the malacocoenoses. Most species were euryoecious and/or widely distributed. The results were compared to other biogeographically and ecologically similar, but mostly less humanaffected areas. The studied habitats showed unbalanced dominance structure, small between-site similarity and small proportion of forest-dwellers, combined with the near-absence or absence of clausiliids and other tree-climbing and/or timber-dependent species.

The females move to the river bank and spurt streams of glochidia-containing water toward the river bed. No similar behaviour has been observed in any freshwater bivalve species to date. Our aim was to verify the hypothesis that it might serve increasing of the glochidia dispersal and thus the probability of host fish infection. In May 2018 in the Biała Tarnowska River near Lubaszowa we measured the length of the mussels, frequency of spurting, spurting distance, volume of the spurted stream of water, number of glochidia per spurt; we recorded the number and behaviour of fishes near the spurting mussels. Statistical analysis showed a significant correlation between the mussel length, spurt volume and maximum spurting distance. There was no statistically significant dependence between the mussel length and number of glochidia per spurt, or mussel length and spurting frequency. The number of glochidia per spurt grew exponentially with the volume. Ca. 70% of fishes near the spurting mussels reacted to their behaviour. Spurting may increase the probability of infection of the host fish, albeit its range is limited. Bivalve reproductive behaviour is mostly unknown, but it may prove crucial to explaining the dramatic drop in abundance of endangered freshwater species. In the case of the thick-shelled mussel impossibility to come on shore to spurt may be the reason for its disappearance from regulated rivers. ALIEN VS.

The reservoir, built in 1961–1965, is situated in the eastern part of Slovakia near the boundary with Ukraine; with its area of 33 km2 it is the second biggest dam reservoir in Slovakia. Nineteen species (13 gastropods, 6 bivalves) were recorded in the first more detailed inventory of its malacofauna. The mollusc communities in individual sites consisted of 8–14 species. The existence of littoral zone overgrown by macrophytes is important especially for populations of pulmonate snails while unionids were usually found on muddy or sandy bottom. Five non-native species were recorded. The abundant population of non-native D. polymorpha probably has a negative impact on unionids because of the shortage of suitable substrata (rocks, stones) for attachment, and as a result D. polymorpha uses shells of dead or live unionids.","PeriodicalId":309868,"journal":{"name":"Folia Malacologica","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126292013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
