SUMMARY 1. The freshwater pearl mussel (Margaritifera margaritifera) is endangered and of conservation importance. We used its survival/mortality during the critical post-parasitic phase as a biological indicator for the habitat quality of the stream substratum. 2. We established and tested biological, physical and chemical methods of assessing the stream bed in 26 streams from seven European countries. We analysed penetration resistance, texture, the concentrations and ratios of C, N, S, P, Fe… 
Impacts of artificial structures on the freshwater pearl mussel Margaritifera margaritifera in the River Dee, Scotland
Freshwater pearl mussels (Margaritifera margaritifera) in the River Dee (north-east Scotland) are in decline, and now occur at low densities with poor recruitment levels. The population's
A case study of a freshwater pearl mussel (margaritifera margaritifera) population in central sweden
Abstract. Most of the Margaritifera margaritifera populations in Sweden are not reproducing. Land use such as forestry, eutrophication and water regulation for hydropower are commonly reported causes
Effects of the endangered freshwater pearl mussel Margaritifera margaritifera on river ecosystem and water quality
Freshwater mussels (Unionoida) can provide valuable ecosystem services through their filtration function, consequently improving or affecting water quality. The endangered freshwater pearl mussel
Habitat traits, population structure and host specificity of the freshwater pearl mussel Margaritifera margaritifera in the Waldaist River (Upper Austria)
TLDR
A comparison of the present stock with data from 1997 revealed a rapid decline in mussel density down to 27%.
Hydrological and substrate requirements of the thick-shelled river mussel Unio crassus (Philipsson 1788)
TLDR
The results indicate that the hydrological and substrate characteristics of U. crassus habitat are broader than expected, and in contrast to the assumption that it depends on moderate to high flows, streams with low water flow and soft substrate were also identified as suitable habitats.
Predicting population status of freshwater pearl mussel (Margaritifera margaritifera, L.) in central Sweden using instream and riparian zone land‐use data
TLDR
It is demonstrated that geospatial data on riparian land-use and cover can be a useful tool for screening waters potentially harbouring non-reproducing mussel populations, and could be used to predict mussel viability.
The relationship between the freshwater pearl mussel (Margaritifera margaritifera) and its hosts
TLDR
The variable suitability of different salmonid strains and species as hosts for M. margaritifera and the resulting differences in the performance of larvae during the host-dependent phase indicate that host-management strategies should focus on maintaining high quality hosts at a regional scale to avoid selection or genetic drift effects which could erode the genetic and evolutionary potential for adaptation to changing environmental conditions.
The first millimetre – rearing juvenile freshwater pearl mussels (Margaritifera margaritifera L.) in plastic boxes
The last remaining population of Margaritifera margaritifera in the Our River (Luxembourg, Europe) has come close to extinction. It consists predominantly of adult animals and will disappear within a

The importance of microhabitat factors and habitat stability to the threatened Louisiana pearl shell, Margaritifera hembeli (Conrad)
TLDR
A discriminant analysis indicated that mussel density was related to water depth, substrate size, substrate compaction, and water velocity, and that mussels were rare in deep, stagnant pools with silt-covered bottoms and were more common in shallow, wide areas of streams with higher current velocities.
Physical microhabitat requirements of freshwater pearl mussels, Margaritifera margaritifera (L.)
TLDR
Adult and juvenile M. margaritifera were found to have broadly similar habitat `preferences', although adults were found over a wider range of physical conditions, and Boulder-stabilised refugia, which contain enough sand for burrowing, are ideal microhabitats for juvenile mussels.
Factors controlling the age structure of Margaritifera falcata in 2 northern California streams

TLDR
Investigation of the factors that shape local M. falcata population age structures yielded insights into the influence of environmental variables and history on mortality and recruitment that will aid conservation of this endangered family of mussels.

Conservation Genetics and Ecology of European Freshwater Pearl Mussels (Margaritifera margaritifera L.)
TLDR
Conservation strategies for pearl mussels can be key examples for the development of conservation strategies for other aquatic organisms and the ecosystem functioning upon which they depend, according to the study on the status of host fish populations and the fish species richness in European pearl mussel populations.
The status of host fish populations and fish species richness in European freshwater pearl mussel (Margaritifera margaritifera) streams
TLDR
It is suggested that 0+ host fish are not necessarily required to sustain functional pearl mussel populations, and low densities of host fish can be compensated by the higher glochidia carrying capacity of older host fish with limited previous contact with pearl mussels, by the long reproductive period of mussel, and by low mortality rates of juvenile mussels during their post-parasitic phase.
The functional role of burrowing bivalves in freshwater ecosystems
TLDR
A clearer picture is needed of the importance of suspension versus deposit feeding and the potential advantages and tradeoffs between these two feeding modes, as well as the role of resource limitation in structuring bivalve communities.
