Development and validation of wetland-connectivity indicators in the U.S. Prairie Pothole Region
We are working in partnership with the U.S. Environmental Protection Agency to (1) quantify cumulative effects of prairie-pothole wetlands on stream communities; (2) explore relationships between aquatic-system connectivity and genetic-, species-, and ecosystem-scale biological diversity at watershed and landscape scales; (3) develop mapping unit descriptors based on biotic community traits for...
Spatial Patterns of Native Freshwater Mussels in the Upper Mississippi River
Impact of UMESC Science This research aims to quantify spatial patterns of adult and juvenile (≤5 y of age) freshwater mussels across multiple scales based on systematic survey data from 4 reaches of the Upper Mississippi River (Navigation Pools 3, 5, 6, and 18). Resource managers can use this critical information about spatial structure to make informed river management decisions.
Movement Patterns of Native Mussels in the Upper Mississippi River: Response to Water Level Management
Impact of UMESC Science This research aims to estimate the fraction of mussels that are able to avoid short-term mortality during a water level drawdown by burrowing or moving horizontally into deeper water. Resource managers can use this critical information about mussel behavior and survival to make informed river management decisions.
Population Assessment and Potential Functional Roles of Native Mussels in the Upper Mississippi River
Impact of UMESC Science The results of this study suggest that native mussels play an integral role in this ecosystem by sequestering large volumes of suspended materials that can be used by other benthic organisms. Managers now have critical data on population size, distribution, and relative health—these data are being used to guide habitat restoration activities to benefit native mussel...
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...
Life History Characterization and Host Fish Identification for Federally Listed and Imperiled Freshwater Mussel Species in the Suwannee River Basin in Georgia and Florida
Freshwater mussels are considered the most imperiled group of animals in the United States. These animals provide valuable ecological services by filtering water, sequestering nutrients, and providing forage for migratory birds, small mammals, and turtles. They also have a unique and complex life cycle that makes them especially vulnerable to human disturbances. It includes a parasitic larval...
