Aquatic malacofauna of the Hrubý Jeseník Mountains, the Rychlebské hory Mountains, the Zlatohorská vrchovina Highlands and the Žulovská pahorkatina Highlands (Northern Moravia, Czech Republic) was investigated in 2000, 2001 and 2003. Altogether 26 species (17 gastropods, 9 bivalves) were found at 56 localities. Species Galba truncatula, Radix peregra s.str., Ancylus fluviatilis and P. casertanum, which often inhabit springs and smaller brooks, belong to the most common molluscs in this territory. Ponds and different water bodies originated by mining enrich aquatic malacofauna of this area by e.g., Lymnaea stagnalis, Gyraulus albus, G. crista, Hippeutis complanatus, Anodonta anatina or Musculium lacustre. The finding of Ferrissia clessiniana is the first record of this non-native mollusc in the territory of Northern Moravia. Water bodies in the Vidnavské mokřiny Wetlands Nature Reserve on the Czech-Poland frontier are inhabited by molluscan community with many species living in lowlands and this community is different in comparison with molluscan communities of the other investigated localities.

Molluscan Fauna

This paper presents results of a malacological survey of four small tributaries of the brook Javorka near Lázně Bělohrad in East Bohemia (Czech Republic). Only 15 species of aquatic molluscs (7 gastropods, 8 bivalves) were found at 31 sites during research realised in 2010, 2011 and 2012. Molluscan assemblages of all tributaries were similar and consisted of common and widespread molluscs as Galba truncatula, Radix peregra, Anodonta anatina, Pisidium subtruncatum or P. casertanum. The occurrence of endangered river pea mussel (Pisidium amnicum) was confirmed at three tributaries but only at lower parts near its inflows to the brook Javorka. The research was focused on the endangered thick-shelled river mussel (Unio crassus), and the occurrence of numerous population was confirmed at the brook Lukavecký potok. In the brook Chotečský potok a small population of this bivalve was found. Only a few specimens were found at remaining two tributaries.

Basic Characteristics

In the pond Strašík by Libouň (Czech Republic, WGS 84: 49°37'50"N, 14°49'30"E) 14 species of water molluscs were documented by the research executed on 8 June 2001: Radix peregra, Lymnaea stagnalis, Anisus vortex, Bathyomphalus contortus, Gyraulus albus, Gyraulus crista, Hippeutis complanatus, Musculium lacustre, Pisidium casertanum, Pisidium milium, Pisidium nitidum, Pisidium obtusale, Pisidium personatum, Pisidium subtruncatum. The basic characteristics of the community were determined: quantitative composition and dominance. The index of the concentrated dominance modified according to Simpson (c = 0,33) was counted and compared with available data. The pond fauna was compared to the fauna of other examined ponds in Podblanicko. The total of 12 ponds were examined in this region or its closest surroundings so far and 21 species of water molluscs were found in them. The pond Strašík, analysed in this study, is richest in species variety, as it has 14 species, the least occupied are the ponds Splav by Bystřice (2 species) and the first pond above the pond Utopenec by Vlašim (3 species). In the case of these ponds the result is probably due to the fact that they are relatively little known. The species Anisus vortex, Lymnaea stagnalis and Gyraulus albus have the highest frequency of occurrence in the ponds examined so far in Podblanicko, the least frequent are the species Bithynia tentaculata, Acroloxus lacustris and Pisidium personatum. The similarity of the species composition of the ponds fauna was evaluated according to the Jaccard’s index. The pond most similar to the Strašík pond analyzed in this study is from the point of view of the species presence the pond Utopenec on the stream Orlina (8 and 12), which is situated nearby.

This paper brings a review of a malacological survey of the northern part of the Orlické Hory Protected Landscape Area, situated in northwestern part of Bohemia (Czech Republic) near boundary between the Czech Republic and Poland. Altogether, only 12 common species of aquatic molluscs (8 gastropods, 4 bivalves) were found. Galba truncatula, Radix peregra, Ancylus ﬂuviatilis, Pisidium personatum, and P. casertanum belong to the most frequent molluscs found during this research. Occurrence of vulnerable or endangered molluscs as well as non-native molluscs was not documented in this area.

Interesting Species

Spiders of Polanská niva National Nature Reserve were investigated during 2013. Several capture methods were used from March to September. Altogether, 85 species from 14 families were recorded. The most interesting species are Arctosa maculata (Hahn, 1822) and Micaria nivosa L. Koch, 1866 (both are vunerable according to the Red List of threatened species in the Czech Republic). The other remarkable species were: Kaestneria pullata (O. P.- Cambridge, 1863), Donacochara speciosa (Thorell, 1875), Hylyphantes graminilola (Sundevall, 1830), Singa nitidula C. L. Koch, 1844 and Trochosa spinipalpis F. O. P.- Cambridge. Evaluation of spider community shows, that 8.2 % spider species prefer naturally like habitats.

Mollusc Species

The Lužnice River and its floodplain are protected in the Horní Lužnice Nature Reserve (Southern Bohemia, Czech Republic). The floodplain has a relatively natural character. Altogether 21 aquatic mollusc species were found at 40 sites. Lymnaea stagnalis, Physa fontinalis, Segmentina nitida and Planorbarius corneus belonged among the most often recorded species. Endangered Pisidium globulare was found. Non-native molluscs were not recorded. Only minimal changes were documented after the first research of this reserve, which was done more than 10 years ago.

A floodplain of the Lužnice river at the Czech-Austrian border is protected by the Krabonošská niva Nature Reserve (Southern Bohemia, Czech Republic). This floodplain has a relatively natural character and, in addition to the Lužnice river, there is a high diversity of habitats at various stages of succession such as oxbows, pools and temporary wetlands. Altogether 20 species were found at 15 sites studied in 2021. Common and widespread gastropods Lymnaea stagnalis, Segmentina nitida and Planorbarius corneus belonged among the most often recorded species. Endangered Pisidium globulare was found at two sites, and only one non-native species Physa acuta was recorded. Molluscan assemblages are very similar to the assemblages of the neighboring Horní Lužnice Nature Reserve.
