“…The resulting COI gene sequences were checked manually using BioEdit v. 7.2.5 [16]. In addition, 255 COI sequences of Anodonta and Pseudanodonta specimens were supplied by NCBI GenBank (partially from our works [11,17] and from works of other researchers [2,12,13,[18][19][20][21][22][23]). Four COI sequences of Sinanodonta lauta (Martens, 1877) [15], S. woodiana (Lea, 1834) [24], Unio pictorum (Linnaeus, 1758) [11], and U. tumidus Retzius, 1788 [11] were used as outgroup for phylogenetic analyses (Table S1).…”

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 and Central Asia, which makes it a convenient object for biogeographic studies. In this study, we analyzed the divergence of A. anatina populations and discovered a separate genetic lineage distributed in rivers of the Azov Sea basin. This was confirmed by the high genetic distances between this group and previously defined populations, and by the position of this clade in the Bayesian phylogeny calibrated by an external substitution rate. Based on our approximate Bayesian computation (ABC) analysis, biogeographic scenarios of A. anatina dispersal in Europe and Northern, Western, and Central Asia over the Neogene–Quaternary were simulated. The haplogroup’s isolation in the rivers of the Azov Sea basin most likely occurred in the Late Pliocene that was probably facilitated by rearrangement of freshwater basins boundaries in the Ponto-Caspian Region. Population genetic indices show the stability of this group, which allowed it to exist in the river basins of the region for a long time. The discovery of a long-term refugium in the rivers of the Azov Sea led to a better understanding of freshwater fauna evolution in the Neogene–Quaternary and highlighted the importance of conservation of these freshwater animals in the region as a source of unique genetic diversity.

“…One could argue that the colouring might be excessively tied to external factors to use it as a taxonomic discriminant. However, this distinguishing character was reported for many A. cygnea and A. anatina populations from other environments and has, therefore, been previously proposed as a character suitable to separate both species (Mordan & Woodward, 1990;Mezhzherin et al, 2014). Differences in pigmentation seem to be associated with the amount and distribution of orange-yellow extracellular calcified granules in interstitial tissues (Colville & Lim, 2003).…”

This is especially evident in anodontine mussels (Reis et al, 2013;Mezhzherin et al, 2014;Klishko et al, 2018), which display considerable intraspecific shell-shape variation caused by shifts of metabolism at sexual maturity, changes in allometric growth and other physiological characteristics (Zieritz & Aldridge, 2011;Klishko et al, 2016). Moreover, the morphometric analyses were more powerful in discriminating between sites of collection of the specimens than between species.…”

“…Another discriminant character is foot and mantle colour, which has been shown to be useful to differentiate A. cygnea from A. anatina (Mordan & Woodward, 1990;Mezhzherin et al, 2014). Indeed, A. anatina and A. exulcerata present a light-brown/ creamy-white colour, whereas A. cygnea is generally bright-orange coloured (Supporting Information, Fig.…”

Freshwater bivalves are highly threatened and globally declining due to multiple anthropogenic impacts, making them important conservation targets. Because conservation policies and actions generally occur at the species level, accurate species identification and delimitation is critical. A recent phylogenetic study of Italian mussel populations revalidated an Anodonta species bringing the number of known European Anodontini from three to four species. The current study contributes to the clarification of the taxonomy and systematics of European Anodontini, using a combination of molecular, morphological and anatomical data, and constructs phylogenies based on complete mitogenomes. A redescription of A. exulcerata and a comparative analysis of morphological and anatomical characters with respect to the other two species of Anodonta present in the area are provided. No reliable diagnostic character has emerged from comparative analysis of the morphometric characters of 109 specimens from 16 sites across the Italian peninsula. In fact, the discriminant analysis resulted in a greater probability of correct assignment to the site of origin than to the species. This confirms the difficulties of an uncritical application of visual characters for the delimitation of species, especially for Anodontinae.

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. complanata are very limited. In this paper, we studied the genetic diversity and differentiation of P. complanata based on newly sequenced COI and ND1 gene fragments, and on available sequences from the NCBI GenBank. We discovered a localized and highly divergent lineage in the Don River basin and a widespread but low diversified lineage distributed from the Volga River basin to the Oise River in France. A star-like haplotype network, results of mismatch analysis, and significant negative values of neutrality tests reveal that the pan-European lineage went through a bottleneck event. The discovery of the separate lineage in the Don River basin is and additional evidence of the existence of Pleistocene glacial refugia in the south of the Russian Plain. Moreover, this finding confirms the significance of the Azov Sea drainage as a freshwater biodiversity hotspot of great conservation importance.
