Distribution and habitat use of the Missouri River and Lower Yellowstone River benthic fishes from 1996 to 1998: A baseline for fish community recovery
M. L. Wildhaber, D. W. Gladish, A. Arab
2011, River Research and Applications (28) 1780-1803
Past and present Missouri River management practices have resulted in native fishes being identified as in jeopardy. In 1995, the Missouri River Benthic Fishes Study was initiated to provide improved information on Missouri River fish populations and how alterations might affect them. The study produced a baseline against which to...

Stephanie S. Romañach, Craig Conzelmann, Adam Daugherty, Jerome L. Lorenz, Christina Hunnicutt, Frank J. Mazzotti
2011, Open-File Report 2011-1272
Estuarine fish serve as an important prey base in the Greater Everglades ecosystem for key fauna such as wading birds, crocodiles, alligators, and piscivorous fishes. Human-made changes to freshwater flow across the Greater Everglades have resulted in less freshwater flow into the fringing estuaries and coasts. These changes in freshwater...
