“…Mussels are among the most threatened North American taxa, with ~70% of species classified as imperilled or endangered in at least a portion of their distribution (Patterson et al, 2018). Past work using genome-wide SNP data helped managers refine conservation decisions in threatened and endangered mussel species (e.g.…”

“…Despite this, many management agencies seeking to enhance wild populations may lack the time or money to sequence at-risk populations before culturing mussels from natural stock for later field release (i.e. propagation, Patterson et al, 2018). The ability to make rapid, low-cost decisions about the best populations to choose individuals for culture from is critical.…”

Community‐wide correlations between species richness, abundance and population genomic diversity in a freshwater biodiversity hotspot

et al. 2023

Understanding patterns of diversity across macro (e.g. species‐level) and micro (e.g. molecular‐level) scales can shed light on community function and stability by elucidating the abiotic and biotic drivers of diversity within ecological communities. We examined the relationships among taxonomic and genetic metrics of diversity in freshwater mussels (Bivalvia: Unionidae), an ecologically important and species‐rich group in the southeastern United States. Using quantitative community surveys and reduced‐representation genome sequencing across 22 sites in seven rivers and two river basins, we surveyed 68 mussel species and sequenced 23 of these species to characterize intrapopulation genetic variation. We tested for the presence of species diversity–abundance correlations (i.e. the more‐individuals hypothesis, MIH), species‐genetic diversity correlations (SGDCs) and abundance‐genetic diversity correlations (AGDCs) across all sites to evaluate relationships between different metrics of diversity. Sites with greater cumulative multispecies density (a standardized metric of abundance) had a greater number of species, consistent with the MIH hypothesis. Intrapopulation genetic diversity was strongly associated with the density of most species, indicating the presence of AGDCs. However, there was no consistent evidence for SGDCs. Although sites with greater overall densities of mussels had greater species richness, sites with higher genetic diversity did not always exhibit positive correlations with species richness, suggesting that there are spatial and evolutionary scales at which the processes influencing community‐level diversity and intraspecific diversity differ. Our work reveals the importance of local abundance as indicator (and possibly a driver) of intrapopulation genetic diversity.

“…The action plans of many species already include artificial propagation as necessary for their recovery (e.g., Araujo & Ramos, ; USFWS, , ). Nevertheless, these strategies should be regarded as temporary measures while natural recruitment is restored by habitat conservation measures (Gum et al, ; Patterson et al, ).…”

“…The worldwide decline of freshwater mussel populations observed in recent times has prompted the creation of conservation programmes around the world. Artificial propagation has become a key conservation management strategy for the restoration and recovery of freshwater mussels (Gum, Lange, & Geist, ; Patterson, Jones, & Gatenby, ; Strayer et al, ). Large numbers of juveniles can be produced in captivity before being reintroduced to the wild.…”

The giant freshwater pearl mussel Margaritifera auricularia (GFPM) is one of the most endangered bivalve species in the world. Originally occurring in many European rivers, the GFPM is a relict now restricted to a few ageing populations in France and Spain in which natural reproduction is almost absent. Like most unionoid mussels, the GFPM needs host fish for the development of their parasitic larvae (glochidia). The European sturgeon (Acipenser sturio), the only known native host fish of the GFPM in France, is essentially extinct. Therefore, the aim of this study was to identify other hosts that could be responsible for the few cases of recent recruitment. Natural infestation of wild fishes in three French rivers was assessed to identify potential hosts of M. auricularia, while artificial infestation experiments were conducted on the sea lamprey (Petromyzon marinus) and the wels catfish (Silurus glanis) to determine their compatibility as hosts. Among the 29 fish species assessed for natural infestation, only the three‐spined stickleback (Gasterosteus aculeatus) and the European eel (Anguilla anguilla) carried M. auricularia glochidia. In the artificial infestation experiments, living juvenile mussels were collected from both P. marinus and S. glanis. The number of juveniles collected from a single P. marinus specimen (13,827) suggests that this species is a highly efficient host. As with previously known hosts, newly identified ones also appear to have a relationship with marine environments. The present findings suggest that P. marinus has played a key role in preventing the total extinction of M. auricularia in France, and indicate the potential use of P. marinus in conservation strategies aimed at reintroducing or stabilizing populations of this rare mollusc.

“…Species reintroduction and population augmentation with captively propagated juveniles and translocation of adult mussels are now widely practiced, particularly in Europe and North America, yet often poorly evaluated (Rytwinski et al, 2021 ). In Europe, the focus of captive breeding has been on the most endangered mussel species such as Margaritifera margaritifera and Unio crassus , whereas it has been applied to a wider range of species in North America (Gum et al, 2011 ; Patterson, Jones, & Gatenby, 2018 ). Most activities typically address a specific conservation goal, such as restoring an extirpated species or removing mussels from construction areas.…”

We identified 14 emerging and poorly understood threats and opportunities for addressing the global conservation of freshwater mussels over the next decade. A panel of 17 researchers and stakeholders from six continents submitted a total of 56 topics that were ranked and prioritized using a consensus-building Delphi technique. Our 14 priority topics fell into five broad themes (autecology, population dynamics, global stressors, global diversity, and ecosystem services) and included understanding diets How to cite this article:
