Data from metabarcoding assays to detect a suite of mussel species using mitochondrial DNA regions of the cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit (ND1) genes sequences.
Increased nutrient and sediment loading have caused observable changes in algal community composition, and thereby, altered the quality and quantity of food resources available to native freshwater mussels. Our objective was to characterize the relationship between nutrient conditions and mussel food quality and examine the effects on the fatty acid composition, growth and survival of juvenile mussels. Juvenile Lampsilis cardium and L. siliquoidea were deployed in cages for 28 d at four riverine and four lacustrine sites in the lower St. Croix River, Minnesota/Wisconsin, USA. Mussel foot tissue and food resources (four seston fractions and surficial sediment) were analyzed for quantitative fatty acid (FA) composition....
Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/jawr.12179/abstract): Freshwater mussels (order Unionida) are a highly imperiled group of organisms that are at risk from rising stream temperatures ( T ). There is a need to understand the potential effects of land use (LU) and climate change (CC) on stream T and have a measure of uncertainty. We used available downscaled climate projections and LU change simulations to simulate the potential effects on average daily stream T from 2020 to 2060. Monte Carlo simulations were run, and a novel technique to analyze results was used to assess changes in hydrologic and stream T response. Simulations of daily mean T were used as input to our stochastic...
Carbon dioxide has shown promise as a tool to control movements of invasive Asian carps. We evaluated lethal and sublethal responses of juvenile fat mucket (Lampsilis siliquoidea) mussels to carbon dioxide concentrations (43–269 mg/L, mean concentration) that are effective for deterring carp movement. The 28-d LC50 value (lethal concentration to 50% of the mussels) was 87.0 mg/L (95% confidence interval, CI 78.4–95.9) and at 16-d post-exposure was 76.0 mg/L (95% CI 62.9–90.3). A proportional hazards regression model predicted that juveniles could not survive CO2 concentrations >160 mg/L for more than 2 weeks or >100 mg/L CO2 for more than 30 days. Mean daily shell growth was significantly lower for mussels that...
The invasive sea lamprey poses a substantial threat to fish communities in the Great Lakes. Efforts to control sea lamprey populations typically involve treating tributary streams with lampricides on a recurring cycle. Elevated densities of sea lampreys in the aquatic corridor between Lakes Huron and Erie prompted managers to propose a treatment using Bayluscide®—a granular lampricide formulation that targets larval sea lamprey that reside in sediments. However, there was concern over the potential for adverse effects of this treatment on native freshwater mussels—imperiled animals that also reside in sediments. We estimated the risk of mortality and sub-lethal effects among eight species of adult and sub-adult...
Abstract: The consequences of global climate change on aquatic ecosystems are predicted to result from altered intensity, variability, and distribution of precipitation, and more frequent flooding and droughts. In freshwater systems, these changes may result in degradation or loss of habitat due to dry stream beds or low flows, and increased water temperatures, pollution, and erosion. Freshwater mussels (Order Unionida) are especially vulnerable to disturbance because they are incapable of escaping detrimental changes at any practical temporal scale. Quantitative information on lethal temperatures (LT) to native freshwater mussels is currently limited to fewer than 10 species, and these few studies have been restricted...

The purpose of this data release and associated data series (Carr and Fancher, 2021) was to compile occurrence records and map the distribution of a freshwater mussel assemblage for the Bureau of Land Management Rapid Ecoregional Assessment for the Southern Great Plains. The freshwater mussel assemblage includes Amblema plicata (threeridge), Fusconaia flava (Wabash pigtoe), Lampsilis cardium (plain pocketbook), Lampsilis teres (yellow sandshell), Pyganodon grandis (giant floater), and Uniomerus tetralasmus (pondhorn). The focal species in the assemblage were selected based on the following criteria: (1) the species are regionally significant, (2) occurrence records are sufficient to map the distribution of the species...
This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species are found in multi-species assemblages suggesting that physical factors influence presence similarly across species. In lotic environments, geomorphic and hydraulic characteristics appear to be important factors for predicting mussel presence. We used maximum entropy (MaxEnt) modeling to evaluate hydrogeomorphic variables associated...
Abstract: Rising environmental temperatures result from changes in land use and global climate and can cause significant shifts in the composition and distribution of species within communities. In freshwater systems, the larval life stage, glochidia, of Unionida mussels develops as an obligate parasite on host fish gills or fins before transforming into the juvenile stage and dropping to the sediment to complete the life cycle. Because of the relationship between freshwater mussels and their often specific host fish species, mussels are not only limited by their own variable thermal tolerances, but also by those of their host fish. Our intent was to compile data from available literature regarding thermal sensitivities...
Abstract: Freshwater mussels are among the most imperiled faunal groups globally, and relevant ecological information is urgently needed to guide their management and conservation in the face of global change. We explored the influence of species traits, host fishes, and habitat at three spatial scales (micro-, reach-, and catchment-scale) on the detection and occupancy of 14 species of freshwater mussels in the Tar River basin, North Carolina. Detection probability for all species was 0.42 (95% CI, 0.36 –0.47) with no species- or site-specific detection effects identified. Mean occupancy probability among species ranged from 0.04 (95% CI, 0.01 – 0.16) for Alasmidonta undulata, an undescribed Lampsilis sp., and...

Data collected from acute 96-hour and chronic 28-day toxicity tests of Aluminum to a commonly tested unionid mussel (Lampsilis siliquoidea) and a commonly tested amphipod (Hyalella azteca) at a pH of 6 and water hardness of 100 mg/L as CaCO3.
Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/jawr.12178/abstract): We developed a stochastic hourly stream temperature model (SHSTM) to estimate probability of exceeding given threshold temperature ( T ) for specified durations (24 and 96 h) to assess potential impacts on freshwater mussels in the upper Tar River, North Carolina. Simulated daily mean stream T from climate change (CC) and land-use (LU) change simulations for 2021-2030 and 2051-2060 were used as input to the SHSTM. Stream T observations in 2010 revealed only two sites with T above 30°C for >24 h and T s were never >31°C for more than 24 h at any site. The SHSTM suggests that the probability, P , that T will exceed 32°C for...

As part of the Genoa National Fish Hatchery Native Freshwater Mussel Restoration Program, U.S. Fish and Wildlife Service researchers utilized advanced technology in mobile rearing to evaluate how different water sources support growth and survival of young freshwater mussels. A mobile aquatic rearing station, or MARS, was deployed along the banks of the Mississippi River in Wisconsin in the summer of 2012 to raise rare and endangered mussel species, including Higgins’ eye pearlymussel, hickorynut, black sandshell and snuffbox. Information gathered will provide a knowledge base for the operation of the trailer moving forward, and will help ultimately optimize rearing techniques in light of expanding natural resource...

North American freshwater mussels are in serious decline as a result of pollution and habitat destruction from human activities. In addition, many mussel species are living in habitats that push the upper limits of their heat tolerance, which may become problematic as the climate and, as a result, water temperatures warm. As part of this project, we created a set of models to predict how freshwater mussels would respond to climate change effects. Our primary objective was to help federal and state natural resource managers forecast how mussel species will respond to climate change over the next 30 to 50 years, so that managers can develop appropriate adaptation strategies to address these changes. Additionally,...
Abstract: Native freshwater mussels are in global decline and urgently need protection and conservation. Declines in the abundance and diversity of North American mussels have been attributed to human activities that cause pollution, waterquality degradation, and habitat destruction. Recent studies suggest that effects of climate change may also endanger native mussel assemblages, as many mussel species are living close to their upper thermal tolerances. Adult and juvenile mussels spend a large fraction of their lives burrowed into sediments of rivers and lakes. Our objective was to measure surface water and sediment temperatures at known mussel beds in the Upper Mississippi (UMR) and St. Croix (SCR) rivers to estimate...
