Abstract Freshwater mussels are ecosystem engineers and keystone species in aquatic environments. Unfortunately, due to dramatic declines this fauna is among the most threatened globally. Here, we clarify taxonomy biogeography of Russian Unionidae based on comprehensive multi-locus dataset sampled date. We revise distribution assess conservation status for each species. This comprises 16 native from 11 genera 4 tribes: Anodonta , Pseudanodonta (Anodontini); Amuranodonta Beringiana Buldowskia...
Freshwater mussels (Bivalvia: Unionoida) play an important role in freshwater habitats as ecosystem engineers of the water environment. Duck mussel Anodonta anatina is widely distributed throughout Europe, Siberia, and Western Central Asia, which makes it a convenient object for biogeographic studies. In this study, we analyzed divergence A. populations discovered separate genetic lineage rivers Azov Sea basin. This was confirmed by high distances between group previously defined...
Freshwater mussels belonging to the tribe Pseudodontini (Bivalvia: Unionidae: Gonideinae) play a keystone role in riverine and lacustrine environments throughout Southeast Asia. Many of them are narrowly endemic habitat specialists, which need special conservation efforts. Unfortunately, systematics this group is rather poorly understood. Here, we show that Pseudodon inoscularis, type species genus Pseudodon, belongs eastern clade (Southeast Asia, east Salween Basin), and, more certainly,...
The duck mussel Anodonta anatina is widely distributed throughout the freshwater basins of Northern, Central, and Western Eurasia, it has a comprehensive genetic structure. This study was devoted to analysis lineages, which are defined based on COI gene sequences. Our new dataset expanded by samples from Northern Central Eurasia. It allowed us reveal high level diversity for trans-Eurasian lineage A. first time. As results, representative Russian Plain, Southern Siberia, Ural region showed...
The accumulation of trace metals in the shells bivalves allows quantitative assessments environmental pollution and helps to reconstruct paleo aquatic environments. However, understanding on how marine freshwater mollusks control level elements their remains very limited. Here, we compared element composition from boreal subarctic habitats, using examples widely distributed species (Mytilus edulis, M. trossulus) (Anodonta anatina, Unio sp., Beringiana beringiana) mussels. Sizable differences...
Trace elements in freshwater bivalve shells are widely used for reconstructing long-term changes the riverine environments. However, Northern Eurasian regions, notably European Russian North, susceptible to strong environmental impact via both local pollution and climate warming, poorly studied. This work reports new data on trace accumulation by widespread species of mussels Unio spp. Anodonta anatina Severnaya Dvina Onega River Basin, two largest subarctic river basins Northeastern Europe....
Abstract Bioerosion is a process with high socio-economic impact that contributes to coastal retreat, and likely increase climate change. Whereas limestone bioerosion well explained by combination of mechanical chemical pathways, the mechanisms silicates, which are harder chemically more resistant, remain elusive. Here we investigated interface between siltstone freshwater rock-boring bivalves Lignopholas fluminalis (Bivalvia: Pholadidae). Remains microbial biofilm were observed only in...
Margaritiferidae is a small freshwater bivalve family with 16 species. In spite of number taxa and long-term history research, several gaps in our knowledge on the pearl mussels still exist. Here we present discovery host fishes for Margaritifera dahurica, i.e. Lower Amur grayling, sharp-snouted lenok, blunt-snouted lenok. The were studied rivers Ussuri Basin. identification glochidia fish hosts was confirmed by DNA analysis. life cycle M. dahurica its are described first time. SEM study...
Freshwater mussels are an endangered group of animals, especially in the water bodies Central and Western Europe. Conservation priorities were established for many freshwater mussel species last decade. Here, we present new data on a cryptic refugium Balkans. Two species, Anodonta exulcerata Porro, 1838 Unio elongatulus Pfeiffer, 1825, discovered Montenegro first time. The phylogenetic position taxonomic status from studied by means integrative approach, combining morphological COI gene...
It is well known that an invasive bivalve mollusk species Dreissena polymorpha plays a significant role as host to parasites. Currently, the interaction between digenean trematodes and their hosts remains relatively poorly understood. In this study we investigate infection of D. by using molecular genetics, histological, light microscopy methods. We obtained sequences one mitochondrial (molecular cytochrome c oxidase subunit 1 (COI)) two nuclear (ITS2, rDNA 28S) gene markers. To best our...
Margaritiferidae is an ancient freshwater bivalve family originated in the Jurassic East Asia. Here, we revise several nominal taxa of fossil pearl mussels that were recovered from Upper Pliocene and Pleistocene deposits Dniester Prut river valleys. Based on morphological stratigraphic data, found these belong to genus Pseudunio are junior synonyms P. flabellatiformis (Grigorowitch-Beresowski, 1915). The new synonymy proposed as follows: Margaritifera (Pseudunio) moldavica Chepalyga, 1964...
The bivalve genus Galatea Bruguière, 1797 (Venerida: Donacidae) was thought to contain exclusively brackish-water clams, the ranges of which are confined estuaries and lower tidal parts large rivers in West Africa. This therefore included global freshwater checklists (Bogan 2013; Graf 2013) as a largely estuarine group. Conversely, review published data alongside our field surveys indicate that at least three populations spp. occur environment, i.e. those from Sanaga (Cameroon), Niger...
The ecological group of mussel-associated freshwater leeches (Hirudinea) contains facultative and obligate inhabitants the mantle cavity mussels (Unionida) from Asia, Africa, North America, South America. Here, we report on record a leech in Europe present list its bivalve hosts. widespread species Helobdella stagnalis (Glossiphoniidae) was recovered as inhabitant native Anodonta anatina, Unio pictorum, U. tumidus, non-native Sinanodonta woodiana (Unionidae). Globally, assemblage 17 species,...
Abstract The Indian subcontinent houses a unique fauna of freshwater mussels. Tectonic and biogeographic reconstructions indicate that this represents derivative Mesozoic Gondwanan biota it arrived in Asia on the Plate, using tectonic block as ‘biotic ferry’. Though preliminary integrative revision Unionidae was published recently, level endemism taxonomic richness regional assemblages are unsatisfactorily known. Here, we revise taxonomy mussels from Brahmaputra River basin based large...
The depressed river mussel Pseudanodonta complanata (Rossmässler, 1835) is an endangered freshwater bivalve with sparse distribution across Europe. Despite its high conservation priority, available data on the current population genetics and biogeography of P. are very limited. In this paper, we studied genetic diversity differentiation based newly sequenced COI ND1 gene fragments, sequences from NCBI GenBank. We discovered a localized highly divergent lineage in Don River basin widespread...
