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...
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...
Dam removal is a potentially powerful tool for restoring riverine habitats and communities. However, the effectiveness of this tool is unknown because published data on the effects of dam removal on in-stream biota are lacking. We investigated the effects of a small dam removal on unionid mussels in Koshkonong Creek, Wisconsin (USA). Removal of the dam led to mortality both within the former impoundment and in downstream reaches. Within the former reservoir, mortality rates were extremely high (95%) due to des- iccation and exposure. Mussel densities in a bed 0.5 km downstream from the dam declined from 3.80 ± 0.56 mussels m)2 in fall 2000 immediately after dam removal to 2.60 ± 0.48 mussels m)2 by summer 2003....
Populations of the freshwater mussel genus Anodonta appear to be in a state of rapid decline in western North America, following a trend that unfortunately seems to be prevalent among these animals (Mollusca: Unionoida). Here we describe the patterns of molecular divergence and diversity among Anodonta populations in the Bonneville Basin, a large sub-basin of the Great Basin in western North America. Using amplified fragment length polymorphism (AFLP) analysis, we found a striking lack of nuclear diversity within some of these populations, along with a high degree of structuring among populations (FST = 0.61), suggesting post-Pleistocene isolation, due either to a long-term loss of hydrologic connectivity among...

The database includes point and stream reach locations of imperiled mussels identified by federal and state governments, universities, and museums in the states of Louisiana, Oklahoma and Texas. Point locations are linked to stream reaches of the National Hydrography Dataset (NHD). Also in this database is the imperiled mussel presence in HUC12 watersheds in Oklahoma from the Watershed Boundary Dataset downloaded on 20150318. This dataset presents the locations of all mussels identified as a Species of Greatest Conservation Need (SGCN) assembled by the Oklahoma Department of Wildlife Conservation for the Oklahoma Natural Heritage Program. Throughout the remainder of these metadata, this group of organisms will be...
