“…The vast number of potential factors contributing to their decline makes it difficult to determine the key chemical contaminants or set of environmental conditions to target in a regulatory framework for protection and conservation (Cope et al 2008). Recent studies on freshwater mussels have documented the impairment of their physiological and biochemical status due to reduced water quality (Lummer et al 2016;Kerambrun et al 2016;Gillis et al 2017). Amongst all the freshwater mussels' families, the Unionidae, in particular, has emerged as a critical group for consideration in the field of ecotoxicology over the past 20 years because of their high sensitivity to chemical exposures and a variety of other environmental stressors, with respect to other groups of organisms (Carella et al 2016).…”

“…Freshwater mussels form a species-rich group of bivalves, with about 900 species present on all continents except Antarctica (Carella et al 2016). They are particularly sensitive to habitat alterations and water quality plays a key role in their distribution (Gillis et al 2017). They are known to be amongst the most endangered groups of animals currently (Machordom et al 2003).…”

The freshwater pearl mussel Margaritifera margaritifera is one of the most threatened freshwater bivalves worldwide. In this study, we aimed (i) to study the processes by which water quality might affect freshwater mussels in situ and (ii) to provide insights into the ecotoxicological significance of water pollution to natural populations in order to provide necessary information to enhance conservation strategies. M. margaritifera specimens were sampled in two close sites located upstream or downstream from an illegal dumping site. The renal transcriptome of these animals was assembled and gene transcription determined by RNA-seq. Correlations between transcription levels of each single transcript and the bioaccumulation of nine trace metals, age (estimated by sclerochronology), and condition index were determined in order to identify genes likely to respond to a specific factor. Amongst the studied metals, Cr, Zn, Cd, and Ni were the main factors correlated with transcription levels, with effects on translation, apoptosis, immune response, response to stimulus, and transport pathways.However, the main factor explaining changes in gene transcription appeared to be the age of individuals with a negative correlation with the transcription of retrotransposon-related genes. To investigate this effect further, mussels were classified into three age classes. In young, middle-aged and old animals, transcription levels were mainly explained by Cu, Zn and age, respectively. This suggests differences in the molecular responses of this species to metals during its lifetime that must be better assessed in future ecotoxicology studies.

“…Earlier population surveys of freshwater mussels in the Grand River watershed (Ontario, Canada) revealed that species diversity has declined by at least 30% in the lower urban‐impacted reaches , putatively a result of poor water quality. Recent population studies in the study area have shown that both species richness and catch per unit of effort declined downstream of WWTPs in the Grand River watershed .…”

The toxicity and bioconcentration of 3 pharmaceuticals (amitriptyline, iopamidol, and sertraline) were examined using multiple life stages (larval, juvenile, and adult) of the unionid mussel Lampsilis siliquoidea. The endpoints examined varied with life stage but included survival, behavior (algal clearance rate, filtering frequency), and oxidative stress. Iopamidol was not toxic at concentrations up to 101 mg/L. Sertraline was the most toxic chemical (50% lethal concentrations [LC50] and effect concentrations [EC50] = 0.02-0.04 mg/L), but exposure did not induce oxidative stress. Glochidia and juveniles were more sensitive than adult mussels. Algal clearance rate in juvenile mussels was the most sensitive endpoint assessed, similar to or lower than the LC50 values for glochidia. However, the compounds examined were not toxic at concentrations detected in the environment. The relative bioconcentration factors were sertraline > amitriptyline > iopamidol. These results suggest that glochidia toxicity could be a screening tool for rapidly assessing the toxicity of chemicals of concern to freshwater mussels.

“…Estimation of mussel age from external annuli is generally unreliable (Neves & Moyer, 1988) and it was ambiguous for many individuals in this study, so we used shell length-frequency distribution as an approximation of population age structure. This method is often employed (e.g., Gillis et al, 2017;Spyra et al, 2012Spyra et al, , 2016, but as ranges of shell sizes differ among different populations of the same species, age-length relationships need to be adjusted. Here, we divided the length range of each species into eight classes, and based on the readings of external annuli in subsamples of individuals in which they were clearly visible, we inferred that the first three length classes corresponded to the age classes of 2-4 years; this is in accordance with S. woodiana growth rates under controlled conditions (Chen, Liu, Su, & Yang, 2015).…”

Silent invasion: Sinanodonta woodiana successfully reproduces and possibly endangers native mussels in the north of its invasive range in Europe

The explosive global spread of Sinadonta woodiana, a large‐bodied unionid mussel of East Asian origin, potentially affects the functioning of freshwater habitats and threatens native mussels. Molecular data indicate that its invasion in Europe started with a single colonization event, followed by in situ adaptation. This study traces one of the possible routes of such adaptation. It documents a population of S. woodiana with a known history of a two‐stage introduction: first, from a heated water source to a production fish pond in northern Poland, and subsequently from that pond to the study site. As the latest local transfer occurred more than 15 years before the study, the abundance of young S. woodiana in various age classes provides proof of ongoing in situ reproduction and resolves the question of the ability of S. woodiana to permanently colonize thermally unpolluted water bodies in areas with prolonged and cold winters. The study also shows that translocations of glochidia‐infested fish and/or adult mussels between water bodies in such areas result in the establishment of new self‐recruiting populations. Together, these findings show that further expansion of S. woodiana into colder regions and establishment of new populations in already invaded areas are to be expected. The relative abundance of S. woodiana and the native unionids: Anodonta anatina and A. cygnea was 40%, 18%, and 42%, respectively. S. woodiana contributed to 65% of the total mussel biomass. Individuals in the first three size classes, corresponding to the 2‐ to 4 year age classes, composed 50% of S. woodiana, 37% of A. anatina, and 26% of A. cygnea. The high proportion of young individuals in S. woodiana indicates population trajectories toward a gradually increasing dominance of this species and possibly reflects its negative impacts via interactions with host fish and competition for resources.
