Native Mussels
Native Mussels
This story map portrays spatial and temporal patterns in native freshwater mussel (Unionioida) assemblage within West Newton Chute, a side channel in navigation Pool 5 of the Upper Mississippi River. Spatial and temporal patterns in species richness and density of three life stages and multiple guilds in this mussel assemblage were explored.

Modeling the Response of Imperiled Freshwater Mussels to Anthropogenically Induced Changes in Water Temperature, Habitat, and Flow in Streams of the Southeastern and Central United States
Freshwater mussels are in serious global decline and urgently need protection and conservation. Declines in the abundance and diversity of North American mussels have been attributed to a wide array of human activities that cause pollution, water-quality degradation, and habitat destruction. Recent findings suggest that many mussel species are already living close to their upper thermal tolerances...
Transformation methods for the glochidia of the spectaclecase mussel Cumberlandia monodonta
The spectaclecase mussel, Cumberlandia monodonta, was effectively listed as federally endangered in April 2012 (https://federalregister.gov/a/2012-5603). It is endemic to the Mississippi, Ohio and Missouri River basins and historically inhabited 44 streams in these basins (USFWS 2014). Currently, the species is known to inhabit 20 of the historical streams, five of which are represented by one or...
The effects of 28-day exposure to elevated C02 on survival, growth and condition of the juvenile life stage of Lampsilis siliquoidea and Lampsilis higginsii mussels
In study AEH-14-COr02, Lampsilis siliquoidea juveniles were exposed to four treatments of CO2, ranging from 43 to 266 mg/L, for 28 days, followed by 17 days post-exposure in untreated water. The resultant median lethal concentration of CO2 that caused 50% mortality (LC50) was 78 ±13 mg/L. The targeted field concentration of a CO2 barrier is 70-80 mg/L. The present study intends to repeat the...
Evaluation of lethal and sublethal responses of dreissenid and unionid mussels to elevated carbon dioxide
Control technology for dreissenid mussels currently relies heavily on chemical molluscicides that can be both costly and ecologically harmful. There is a need to develop more environmentally neutral control tools to manage dreissenid mussels. Carbon dioxide has shown toxicity to several species of invasive bivalves, including zebra mussels (Dreissena polymorpha) and the Asian clam (Corbicula...
