Fish Community Assembly in the Missouri River Basin
Warmwater fish communities of the Missouri River basin are poorly studied. I conducted a series of investigations intended to explain fish community structure and composition therein. I focused on relations between environmental characteristics and fish species because abiotic factors are …

RELIABILITY-BASED MODELING FOR MISSOURI RIVER DAM SYSTEM
… results and analysis of our application in the Missouri River mainstem reservoir system. In addition, four scenarios which Corps engineers are going to consider, have been applied to explicit the impacts of modeling system with different maintenance strategies. Besides, we used the stochastic …

Productivity and Trophic Interactions in the Missouri River Impoundments
… is a vital component of fisheries assessment in Missouri River impoundments. In South Dakota, annual variation in fish growth and abundance is used to monitor changes in fish populations and develop strategies (i.e. regulations) for managing recreational fishes. Although variation in fish …

Seasonal Use of Missouri River Reservoir Deltas by Fishes
… in the littoral habitats of reservoirs on the Missouri River and collected fishes in deltas habitats. I focused on two research topics during this study: 1) recent changes in littoral habitats resulting from sedimentation and shoreline erosion, and 2) the seasonal use of delta habitats by …

Sauger Population Ecology in Three Missouri River Mainstem Reservoirs
… habitat alterations associated with regulated rivers. Several sauger populations within the Missouri River basin are also experiencing similar declines, particularly in the headwaters of Montana, and the lower basin states of Nebraska and Missouri. However, sauger populations in many of the …

Upper Missouri River Basin Aquatic GAP Fish Distribution Model Accuracy Assessment and White Sucker, Catostomus commersonii, Population Characteristics in the Upper Missouri River Basin
… at 61 sites in 6 drainages throughout the upper Missouri River Basin. A total of 21,204 fish were collected, representing 42 species and 11 families. Minnows (family Cyprinidae) dominated the catch (77.9%), followed by suckers (family Catostomidae, 6.5%), and catfishes (Ictaluridae, 5.7%). Of the …

Conservation genetics of sauger in the upper Missouri River drainage
… role in sauger declines throughout the upper Missouri River drainage of Montana and Wyoming. I identified 11 microsatellite loci to detect interspecific hybridization and describe the genetic population structure of sauger. Two major population groupings of sauger were revealed by principal …

Intraspecific Variation Among Emerald Shiners (Notropis atherinoides) of the Missouri River
Fishes of the Missouri River are separated by six dams and impoundments and inhabit a variety of natural and engineered habitat types. Concern over the effects of river alteration led to an investigation of whether the Missouri River fish have been segregated into differentiated sub-populations. …

Wildlife Habitat Evaluation of the Unchannelized Missouri River in South Dakota
… delineated, and measured along the unchannelized Missouri River in South Dakota. Agricultural and urban developments existed on 60 percent of the land within 1 km of the river. Six habitat types made up the non-developed land in the study area: cottonwood-dogwood (16 percent), cottonwood-willow (9 …

Bedform and Flow Relationships, Little Missouri River Near Medora, North Dakota
… conditions over known bedforms in the Little Missouri River were used to seek relationships between the two. The flow parameters that were measured included: current velocity, depth, water temperature, and suspended-load concentration. A bedload sample was also taken at each bedform. The …

Stream piracy and glacial diversion of Little Missouri River, North Dakota
<p>Bedrock river terraces, as much as 275 to 500 feet above the present Little Missouri, are remnants of a former floodplain. The presence of these former shallow valley floor (Little Missouri Terrace No. 4) along the pre-glacial channel and east and north of the Killdeer Mountains suggests several …

Population Dynamics of Piping Plovers (Charadrius melodus) on the Missouri River
… limiting the growth of this population. On the Missouri River, piping plovers nest on sandbars, but the damming of the mainstem of the Missouri in the mid-twentieth century reduced the natural capacity of the Missouri River to create sandbar habitat. In 2004, the United States Army Corps of …

Groundwater flow in part of the Little Missouri River Basin, North Dakota
<p> The Little Missouri valley in western North Dakota is deeply incised into slightly permeable Mesozoic and Cenozoic sediments. An evaluation of the groundwater flow in part of this valley was 'based on the present groundwater flow-system models. Abrupt changes in the hydrochemical facies have …
