Article

The early post-parasitic phase is considered to be the most vulnerable life-stage of the endangered freshwater pearl mussel (Margaritifera margaritifera), yet little is known about the spatial variability in juvenile performance at a river scale. The main aim of this study was to determine within-river variation in habitat suitability for juvenile...

Knowledge of habitat suitability for freshwater mussels is an important step in the conservation of this endangered species group. We describe a protocol for performing in situ juvenile exposure tests within oligotrophic river catchments over one-month and three-month periods. Two methods (in both modifications) are presented to evaluate the juveni...

Sediment depth preference was tested on 1-year-old freshwater pearl mussel juveniles. Mesh tubes allowing vertical migration with a possibility to leave hyporheic space, filled with 1–2-mm granulometry size substrate and populated with groups of juveniles, were placed in the natural river bed of the Teplá Vltava River, Czech Republic. The depth pos...

Action plan for freshwater pearl mussel in the Czech Republic The effort for Czech freshwater pearl mussel conservation was started in 1982. In 1993, the official ratification of conservation efforts resulted in the introduction of the action plan for freshwater pearl mussel. It is approved by the Ministry of the Environment of the Czech Republic a...

Since 1980, due to an alarming decline of FPM population, missing reproduction and the deteriorating quality of entire unique oligotrophic river catchments, the activities to protect them are ongoing. Gradually, declarations of a first action plan for the FPM and its habitats and declaration of protected areas in most of FPM catchments with a detai...

Despite the large number of studies devoted to organic matter dynamics in fluvial ecosystems, the detrital pathways of spring headwater systems remain neglected. In particular, spring wetlands (helocrenes or seepages) might have considerable influence on downstream headwater stream systems due to the alteration of the nutrient and organic matter co...

Land use is a predominant threat to the ecological integrity of streams and rivers. Understanding land use-water quality interactions is essential for the development and prioritization of management strategies and, thus, the improvement of water quality. Weighting schemes for land use have recently been employed as methods to advance the predictiv...

It had been known that the critically endangered freshwater pearl mussel (Margaritifera margaritifera) still occurs somewhere in the upper parts of the Malše River in South Bohemia, on the border between the Czech Republic and Austria. The fact that the Malše forms a state border here was hampering a detailed biological survey for a long time, and...

The research of the Czech and Slovak mollusc fauna has a long tradition spanning the last 150 years. Particularly, in the last two decades, existing records were put in databases and distributional maps for most species are available on-line. The journal Malacologica Bohemoslovaca, which focuses on publishing faunistic studies from Europe, has been...

Aquatic areas within nature reserves can suffer from certain anthropogenic pressures of its visitors. The littoral zone within small rivers and lentic freshwater systems is particularly threatened by water sports, such as swimming and canoeing. The core zone of the Central European National Park is an example of a popular location for visitors and...

Action plan methods for the freshwater pearl mussel (Margaritifera margaritifera) IN CZECH In the Czech Republic, the freshwater pearl mussel (a bivalve mollusc) is a critically endangered species, strictly tied to oligotrophic streams. The survival of fragmented populations depends on the water quality but also on the state of watersheds and thei...

It is well known that land snails can be dispersed by birds, both by attachment to the body (ectozoochory) and by passing intact and alive through the bird's digestive tract (endozoochory). Endozoochory has, however, only been recorded for very small species. We examined the possibility that larger species (up to c. 17 mm in maximum shell dimension...

The freshwater pearl mussel was historically abundant in many streams and rivers in the Elbe, Oder and Danube Basins in the Czech Republic, Central Europe. By the 21st century, the mussels had become extinct in the lower and middle altitudes, and current populations are only present near the upper limit of their natural range. The current populatio...

Drobní schránkatí plži se mohou aktivně šířit pouze na malé vzdálenosti. Mezi další možnosti šíření patří pasivní disperze. Významným přenosovým vektorem, jak ve své práci dokazuje například Wada a kol. 2012, mohou být některé druhy ptáků. Naše práce se zaměřila na možnosti ekto- i endo- ornitodisperze prostřednictvím vybraných druhů ptáků vyskytuj...

Ralská plošina (bývalý vojenský prostor Ralsko a blízké okolí) je tvořená především minerálně chudým pískovcovým podložím pokrytým borovými lesy a jedná se tedy o prostředí na schránkaté zemní plže velmi chudé. Výjimkou jsou bazické vyvřelinové výchozy, na kterých se nachází pralesovité listnaté lesy s poměrně bohatými společenstvy plžů. Tyto lokal...

This article summarises data on the presence of the freshwater pearl mussel (Margaritifera margaritifera) in the upper part of the Vltava River basin in the Bohemian Forest (Šumava in Czech) and the Novohradské Hory mountains. The data gathering was based on standard Czech methods. Apart from the well-documen-ted situation in the protected National...

We analyzed the composition of spring fauna in relation to the mesoscale variability in environmental conditions in 77 permanent springs in a geologically homogenous area. We hypothesized that the species would occur in definite patterns reflecting the differences in factors that operate at the spring-level scale. We focused on the differences resu...

Fine particulate organic matter (FPOM), originated by aggregation of smaller particles and by decomposition of bigger particles, usually presents the dominant energy and nutrient source in the primary river net. Relationships between detrital components, environmental factors and macroinvertebrate composition were investigated in 52 submontane orga...

In recent years, the importance of wastewater treatment in small municipalities has risen as the pollution from agriculture has decreased. A typical example is the municipality of Zbytiny, which requires higher wastewater treatment efficiency than usual for a village of its size. This is because of the occurrence of freshwater pearl mussels in the...

This paper presents a part of the results obtained from extensive studies conducted on springs — remarkable freshwater habitats with many unique characteristics and a high degree of biological diversity. The abiotic conditions and fauna composition of 68 submontane permanent oligotrophic springs in the Blanice River catchment (eastern part of The B...

Perlorodky se stejně jako naši ostatní mlži živí filtrováním mikroskopických částeček z vody. Vodu nabírají pootevřenými lasturami a díky složitému mechanismu jsou schopny zachytit částečky až do velikosti tisíciny milimetru. Vytvoří z nich balíček, který posunou k ústnímu otvoru, skrytému uvnitř schránky. Umí také oddělit nepoživatelné částice jak...

The pearl mussel (Margaritifera margaritifera) is an indicator of non-polluted oligotrophic streams. Hydrochemical investigations have been conducted at 6 localities in the Czech Republic since 2000. The study involves monitoring key parameters of water quality (conductivity, nitrates, pH) in the network of profiles, analysis of interstitial water...

Project
The Interreg project Malšemuschel tries to bring together topical issues like erosion and therefore anthropogenically induced high loads of fine sediment and sand in riverine ecosystems, aquatic ecology, fisheries, flood protection, water management and climate change adaptation. In the area of the Bohemian Massif, the freshwater pearl mussel is highly suitable as an indicator for a sustainable river basin management. The complex life-circle, with the vulnerable juvenile phase, makes the species strongly dependent on the hydrological and sediment conditions. The project mainly focuses on a better process understanding, an integrative view on the multifactorial threats to the landscape-river-system, and the conception of measures in the catchment. I addition, young Freshwater Pearl Mussels are reared, fishery management measures are introduced, and interaction with the local stakeholders is strengthened.
