Population Dynamics of Threatened Piping Plovers on the Niobrara River, Nebraska
Prairie rivers of the Great Plains, USA, provide important habitat for the federally threatened piping plover (“plover”, Charadrius melodus). Plovers nest on open to sparsely vegetated river sandbars, and their demographic rates are closely linked to habitat availability and quality, as well as …

Establishing an unambiguous connection between grain size and style of sediment transport in the Lower Niobrara River, Nebraska, USA
… application of this method in natural, sandy rivers is difficult due to large variabilities in flow. We propose a method for determining local flow conditions using the distribution of grain sizes traveling in the water column. Local shear velocity is found by fitting the Rouse equation for …

Distribution, Productivity, and Habitat Use by Interior Least Terns and Piping Plovers on the Niobrara River in Northern Nebraska, 1996-1997
… Act since 1985. Dam building on the Missouri River has produced changes in the availability and suitability of nesting habitats while both species continue to experience population declines throughout their range. The Niobrara River in Nebraska is one of the least modified rivers in the …

Macroinvertebrate Composition and Patterns of Prey Use By Juvenile Pallid Sturgeon (Scaphirhynchus albus) in the Missouri River, South Dakota, and Nebraska
… were collected from the Missouri River downstream of Fort Randall and Gavins Point dams to evaluate spatial and temporal patterns in abundance and describe habitats important for macroinvertebrates. The most abundant families collected were Chironomidae, Ceratopogonidae, …

Seasonal Use of Missouri River Reservoir Deltas by Fishes
… 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 fishes. …

Sampling Techniques for Juvenile Pallid Sturgeon and the Condition and Food Habits of Sturgeon in the Missouri River Below Fort Randall Dam, South Dakota
… pallid sturgeon (HRJPS) throughout the Missouri River to help facilitate recovery and long-term monitoring programs were established to evaluate sturgeon populations and the associated fish community. However, there is limited knowledge on how and when to effectively sample for juvenile pallid …
