Documenting Change At Upper Hamburg Bend: Nebraska's First Side-Channel Restoration, Brandon L. Eder, Gerald Mestl
Documenting Change At Upper Hamburg Bend: Nebraska's First Side-Channel Restoration, Brandon L. Eder, Gerald Mestl
Great Plains Research: A Journal of Natural and Social Sciences
In 1996 a side channel was excavated on 629 hectares of former agricultural land at Upper Hamburg Bend on the Missouri River in Otoe County, NE. This was the first side channel constructed on the Missouri River in an attempt to restore lost aquatic habitat. The initial design was for an approximately 4,200 m long side channel to be constructed with a 3 m bottom width. Development ofthe site was to be dependent on flows diverted from the main channel of the river with a final projected top width of 61 m. The side channel was completed in the spring, …
Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper
Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper
Great Plains Research: A Journal of Natural and Social Sciences
Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …
Reconsidering National Park Interpretation Of The Great Plains And Trans-Mississippi West, Robert Pahre
Reconsidering National Park Interpretation Of The Great Plains And Trans-Mississippi West, Robert Pahre
Great Plains Research: A Journal of Natural and Social Sciences
The National Park Service has generally interpreted its sites in the Great Plains in terms of a Eurocentric narrative of westward expansion. Though some sites are changing (e.g., Little Bighorn), others are not (e.g., Scotts Bluff). Even those sites that have changed still retain important elements of traditional narratives, which often date to the 1930s or to the Mission 66 period (1956-66). The newest sites, such as Washita Battlefield, tell newer stories that resonate well with today's visitors. These provide a model for revising older sites. Giving greater attention to causes and consequences, aiming for a richer mix of disciplinary …
A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell
A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell
Great Plains Research: A Journal of Natural and Social Sciences
As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …
Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible
Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible
Great Plains Research: A Journal of Natural and Social Sciences
We evaluated the reproductive biology of314 white-tailed jackrabbits (Lepus townsendii) in 44 counties throughout South Dakota from June 2004 to September 2005. We classified jackrabbits as juveniles or adults based on the closure of the proximal epiphysis of the humerus using X-ray analysis. We determined annual reproductive activity through fluctuations in measured weights of reproductive organs for both sexes. The 2005 breeding season started in late February and proceeded until mid-July, approximately 142 days, allowing for females to potentially produce 3.3 litters. We found four distinct breeding periods by the overlap of estimated conception and parturition dates. Mean …
Hydrological Effects And Groundwater Fluctuations In Interdunal Environments In The Nebraska Sandhills, David Gosselin, Venkataramana Sridhar, F. Edwin Harvey, James Goeke
Hydrological Effects And Groundwater Fluctuations In Interdunal Environments In The Nebraska Sandhills, David Gosselin, Venkataramana Sridhar, F. Edwin Harvey, James Goeke
Great Plains Research: A Journal of Natural and Social Sciences
Nine years of groundwater monitoring data has documented the important influence that topographic relief and location in the groundwater flow system have on the hydrologic function of interdunal valleys. The western "wet" valley at the Gudmundsen Sandhills Laboratory in central Nebraska, which is a net discharge area, is more strongly buffered from the effects of annual-scale climatic variability than the eastern "dry" valley. The east valley is generally an area of net recharge and as such is more responsive to climatic variability. This study employed a simple water balance approach to estimate evapotranspiration (ET) from water level measurements in the …
Reviews Of Fatal Harvest: The Tragedy Of Industrial Agriculture And The Fatal Harvest Reader: The Tragedy Of Industrial Agriculture, Edited By Andrew Kimbrell, Charles A. Francis
Reviews Of Fatal Harvest: The Tragedy Of Industrial Agriculture And The Fatal Harvest Reader: The Tragedy Of Industrial Agriculture, Edited By Andrew Kimbrell, Charles A. Francis
Great Plains Research: A Journal of Natural and Social Sciences
Fatal Harvest introduces and dispels key myths about industrial agriculture: greater efficiency; safe and nutritious food that is cheap to consumers; benefits to wildlife and environment; how biotechnology will save the world. In essays by leading proponents of a more equitable and sustainable food system, the book presents compelling evidence that alternative systems guided by an agrarian ethic will better address our food needs while protecting our natural environment and soil resources.
Wendell Berry cites the separation of people from their food supply and natural environment as a causal factor in our ready acceptance of today's industrial agriculture. When we …
Review Of Planting The Future: Developing An Agriculture That Sustains Land And Community Edited By Elizabeth A. R. Bird, Gordon L. Bultena, And John C. Gardner, Charles A. Francis
Review Of Planting The Future: Developing An Agriculture That Sustains Land And Community Edited By Elizabeth A. R. Bird, Gordon L. Bultena, And John C. Gardner, Charles A. Francis
Great Plains Research: A Journal of Natural and Social Sciences
Why should you care about agriculture? Planting the Future provides an eloquent description of the current state of this' most basic human endeavor so critical to survival. Based on a series of surveys and on-farm studies in the North Central and Western states, the book recognizes the bounty of our conventional agricultural industry. More importantly for the future, it details a series of critical problems in the environment, the distribution of economic benefits, and the social dislocation resulting from the consolidation of lands and heavy reliance on fossil fuels. Today's productivity and cheap food in the market have hidden expenses …
