Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/fwb.12290/abstract): Freshwater mussels (Unionidae) are a highly imperilled faunal group. One critical threat is thermal sensitivity, because global climate change and other anthropogenic activities contribute to increasing stream temperature and altered hydrologic flow that may be detrimental to freshwater mussels. We incorporated four benthic environmental components – temperature, sediment, water level (a surrogate for flow) and a vertical thermal gradient in the sediment column – in laboratory mesocosm experiments with juveniles of two species of freshwater mussels (Lampsilis abrupta and Lampsilis radiata) and tested their effects on survival, burrowing...

Freshwater mussels native to the Southeastern and Mid-Atlantic regions of the United States are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Even greater risks to these species stem from the stresses associated with climate change-induced sea level rise, such as changes in salinity, water temperature, and stream flow. This research investigates the potential vulnerability and adaptation of native freshwater mussels associated with changes in salinity. This dataset contains raw survival and LC50 data generated when conducting acute toxicity tests on three species of freshwater mussels, exposing them to a synthetic sea...

Sea levels across the planet are rising, particularly along the eastern coast of the United States. Climate-induced sea level rise can result in the inundation and intrusion of seawater into freshwater drainages. This would alter salinity regimes and lead to the salinization of coastal freshwater ecosystems. Increased salinity levels in freshwater can negatively affect freshwater-dependent species, including native mussels belonging to the order Unionida, which are highly sensitive to changes in water quality. Sea salt is largely made up of sodium and chloride ions, forming sodium chloride, a known toxicant to freshwater mussels. However, sea salt is a mixture that also contains other major ions, including potassium,...

Native freshwater mussels of the family Unionidae are experiencing high imperilment status due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. The Southeastern, Mid-Atlantic, and Midwestern regions of the United States contain the greatest biodiversity of native freshwater mussels in the world and are now at even greater risk from the continued stresses of human-mediated changes to the landscape through urban and rural development, mining activities, climate change, nutrient influx and their associated impacts to water and sediment quality. The specific objectives of this study are to (1) Compare the relative sensitivity of early life stages...
