Special Issue Information

Dear Colleagues,

Freshwater mussels (Bivalvia: Unionida) are a diverse group of freshwater molluscs with a worldwide distribution. They are an integral part of ecosystems and provide key functions including biofiltration, nutrient cycling and storage, habitats for aquatic communities, and food resources for other species. Due to current anthropogenic stressors and rapidly changing environments, freshwater mussels have been experiencing severe population decline across the world, making them one of the most endangered group of animals. Despite extensive research and conservation efforts, knowledge gaps in the diversity, distribution, and ecology of freshwater mussels hinder effective and efficient species recovery and conservation management. In this Special Issue of Diversity, we would like to offer a platform to present recent studies on the diversity and conservation of freshwater mussels across the world. We especially encourage the submission of studies on freshwater mussels in understudied regions. Through this Special Issue, we hope to increase our knowledge of freshwater mussels and provide the best available science to protect this most endangered group of animals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

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. Full article

The basic knowledge of freshwater bivalves in the Unionida in some regions of the world is still limited, hindering potential conservation efforts, including in Vietnam. A subset of these mussels, the freshwater bivalve tribe Anodontini, is especially difficult to properly identify morphologically due to intraspecific shell similarity. This study aims to define the species of Anodontini in Vietnam and describe their evolutionary relationships and distributions by estimating phylogenies and analyzing collected specimens. The Anodontini are represented in Vietnam by five species divided among three genera: Sinanodonta, Cristaria, and Pletholophus. Sinanodonta woodiana, a large species complex, is represented in Vietnam by Sinanodonta jourdyi. Cristaria is confirmed to include the widespread Cristaria plicata and substantiates the validity of Cristaria truncata. Finally, Pletholophus is here recognized as distinct from Cristaria, containing two species in Vietnam, Pletholophus tenuis, and a species new to science. Our study is an important baseline for future studies on Vietnamese freshwater mussels and highlights the importance of surveys, molecular work, and taxonomic expertise to describe the biodiversity of understudied regions.
