(SW Slovakia) during the researches in 2008–2009. Fifty two species were recorded in alder carrs and 32 species in adjacent forests. Woodland species sensu stricto (17 species, 32.7%) and euryecious species (10 species, 19.2%) predominated in alder forests. Dominant ecological groups in beech and hornbeam forests were woodland species sensu stricto (14 species, 43.8%) and woodland eurytopic species (6 species, 18.8%). There were 28 species (433 individuals) at the highest species richness site (Lozorno, alder carr). Generally, the species richness was higher in alder forests in comparison to beech or hornbeam forests. As expected, there was a higher number of species at the carbonate sites than non-carbonate sites. The following species were recorded in the Small Carpathian Mts. for the first time: Deroceras rodnae s. lat. Grossu et Lupu, 1965, Deroceras turcicum (Simroth, 1894) and freshwater snail Gyraulus rossmaessleri (Auerswald, 1852).

Study revealed 34 aquatic gastropods representing 30% of Prosobranchia and 70% of Pulmonata. Obtained data showed higher mollusc diversity in the littoral biotopes in comparison with open areas of the Lagoon. The fauna is represented by a typical Central European species complex of freshwater gastropods. The reed zone along the coastline in the Lagoon functions as a barrier and provides shallow water habitats with slow moving and warmer water, where maximum gastropod species concentrate.

This sampling method also allows us to detect the presence of rare and endangered species in the study area. We studied flood debris along the Neresnica River to gather data on mollusc fauna of the Pliešovská Kotlina basin and the Javorie Mts. (Central Slovakia). In spring 2010, samples of flood debris were taken at three sites along the river. Molluscan thanatocoenoses were composed of 68 species (56 terrestrial and 12 aquatic ones). The most notable records were two subterranean species – Lucilla scintilla and L. singleyana, and also the species of nature conservation interest – Vertigo angustior. We found representatives of all ecological groups of molluscs, which provide the evidence of ecosystem diversity in various habitats along the river. We documented that the land use of the studied drainage basin was only partially reflected by the structure of mollusc assemblages from flood deposits.

This article presents results of malacological survey in the Loucké Rybníky ponds (Karviná-Louky, Czech Republic) conducted in 2006 and 2007. The samples were collected at seven locations which match with sites sampled in 1954 and 1978; the location of sites were detected based on original schematic maps showing their position. The research was focused on aquatic species, terrestrial mollusc were collected only marginally. In 2006 and 2007, 38 mollusc species were found (35 gastropods and 3 bivalves), which include 17 species of aquatic molluscs and 21 terrestrial. Based on comparison with the data collected in 1954 and 1978 we conclude that the total destruction of aquatic habitats was irreversible and lead to changes in the species composition. Several rare and endangered species have extinct at this site and the total species richness of aquatic species decided from 29 to 17.

It is formed by rocks of the te­schenite association. It was opened as relatively small picrite quarry with further enlargement due to gravel mi­ning up to present status. Quarries in general possess wide range of habitats. Moreover, teschenite rock association with its high calcium content is favourable environment for land snails. Altogether, 27 land snail species were found in Hončova Hůrka hill, of which four are concerned as near threatened (Ena montana, Vertigo pygmaea, Daudebardia rufa and Pupilla muscorum). This site thus has a potential as local refugium for endangered species and deserves our attention.

Altogether, 75 species of terrestrial Gastropoda representing 30% of the total Czech malacofauna, were recorded at sites selected during previous and recent research from 1950−2010. The Ohře malacofauna is impoverished of many forest and floodplain species in comparison to molluscan assemblages of smaller Bohemian rivers to the west and northwest. The richest molluscan assemblages occur on the upper part of the river, while the middle and lower parts are very poor. Low alpha-diversity of these parts of the Ohře River can be explained by (1) intensive agriculture in floodplain areas of the middle part of the river, (2) the migration barrier of the Nechranice Dam between the upper and middle river parts, and (3) long-term human influence on the lower part of the Ohře River during the Holocene.

We found several species with Carpathian distribution, and the study area is probably the easternmost locality of these species. The Humosu Forest Reserve is the fourth locality of Serrulina serrulata (L. Pfeiffer, 1847) in Romania. The species survival requires occurrence of preserved old-growth forests with decaying tree trunks and logs. Wed, 10 Aug 2011 23:45:00 +0100 http://mollusca.sav.sk/pdf/10/10.Pall-Gergely.pdf
