New Distributional Records Of Great Plains Pseudo Scorpions (Arachnida: Pseudoscorpiones), Paul O. Cooney, James A. Kalisch
New Distributional Records Of Great Plains Pseudo Scorpions (Arachnida: Pseudoscorpiones), Paul O. Cooney, James A. Kalisch
Great Plains Research: A Journal of Natural and Social Sciences
Pseudoscorpions are tiny, oval, brown, flattened arachnids that possess large "pinchers" in front of the body for capturing smaller prey. They generally live in forested habitats in soil litter or beneath loose bark. It has been presumed that pseudoscorpions are scarce in the Great Plains, except for along rivers, due to harsh climatic conditions. However, new records of pseudo scorpions from the Great Plains were derived from identification of specimens obtained from university and college collections, and from specimens collected by the first author. Records provided new revelations about distributions of not only the more commonly known pseudoscorpion species but …
Near-Surface Soil-Water Monitoring For Water Resources Management On A Wide-Area Basis In The Great Plains, K. G. Hubbard, J. You, V. Sridhar, E. Hunt, S. Korner, G. Roebke
Near-Surface Soil-Water Monitoring For Water Resources Management On A Wide-Area Basis In The Great Plains, K. G. Hubbard, J. You, V. Sridhar, E. Hunt, S. Korner, G. Roebke
Great Plains Research: A Journal of Natural and Social Sciences
In the Great Plains, soil water is one of the most critical factors related to sustainable production on cropland and rangeland, while the need for better water management grows in the face of increasing water demand during dry years. Soil water is also an important factor related to flood modeling and quantification of the boundary conditions in atmospheric models such as global circulation models. The objectives of this study were to install a wide-area automated soil-monitoring network, determine effective calibration procedures, and develop new products to illustrate the status of soil water. Soil-monitoring sensors were established at 51 sites across …
Producer Responses To Carbon Sequestration Incentives In The Northern Great Plains, Dean A. Bangsund, F. Larry Leistritz
Producer Responses To Carbon Sequestration Incentives In The Northern Great Plains, Dean A. Bangsund, F. Larry Leistritz
Great Plains Research: A Journal of Natural and Social Sciences
Agricultural lands can be used as a terrestrial sink for atmospheric CO2 by changing their management and/or use. The goal of this study was to evaluate the economic potential of carbon sequestration on cropland in the spring wheat producing region of the northern Great Plains. In order to provide a more realistic assessment of the economic potential for agricultural carbon sequestration, this study reflects regional trends in land management practices, incorporates the value of co-products from the conversion of cropland to permanent grass, and considers producer differences in crop production profitability. The economic model compared the expected net present …

Elk (Cervus elaphus) were historically found throughout North America but were extirpated from Nebraska and much of the Great Plains in the 1880s due to consumptive uses by settlers, miners, market hunters, and others. Elk began to reappear in Nebraska in the 1950s and 1960s, and established a stable, nonmigratory population that currently consists of seven herds and an estimated 1,400 individuals throughout western and central Nebraska. The reappearance and subsequent persistence of elk in Nebraska suggests there is adequate habitat to support a self-sustaining population. The general movement of elk eastward may lead to an eventual statewide …
Regional Dynamics Of Grassland Change In The Western Great Plains, Mark A. Drummond
Regional Dynamics Of Grassland Change In The Western Great Plains, Mark A. Drummond
Great Plains Research: A Journal of Natural and Social Sciences
This paper examines the contemporary land-cover changes in two western Great Plains ecoregions between 1973 and 2000. Agriculture and other land uses can have a substantial effect on grassland cover that varies regionally depending on the primary driving forces of change. In order to better understand change, the rates, types, and causes of land conversion were examined for 1973, 1980, 1986, 1992, and 2000 using Landsat satellite data and a statistical sampling strategy. The overall estimated rate of land-cover change between 1973 and 2000 was 7.4% in the Northwestern Great Plains and 11.5% in the Western High Plains. Trends in …
Physiological Responses Of Four Hazelnut Hybrids To Water Availability In Nebraska, Tala Awada, Scott Josiah
Physiological Responses Of Four Hazelnut Hybrids To Water Availability In Nebraska, Tala Awada, Scott Josiah
Great Plains Research: A Journal of Natural and Social Sciences
Responses of hazelnut hybrids (88BS, BOX1, Gl7, and GEL502) to water availability (watered and nonwatered) were examined in the field. The study site received 35% of long-term average precipitation between July and September. Photosynthesis (A), stomatal conductance (gs), water potential (Ψ), and specific leaf area were generally lower in the nonwatered than in the watered treatment and exhibited significant seasonal decline, which was accompanied by an increase in water use efficiency (WUE) under both water treatments. Hybrids exhibited different strategies to cope with water availability. The hybrid 88BS was more water conserving, with the most decline in g …
Global Change In The High Plains Of North America, Jane H. Bock, William D. Bowman, Carl E. Bock
Global Change In The High Plains Of North America, Jane H. Bock, William D. Bowman, Carl E. Bock
Great Plains Research: A Journal of Natural and Social Sciences
The High Plains of North America extends from Canada to northern Mexico. This grassland region is subject to prolonged drought, herbivory, and wildfire. Organisms that are indigenous to the High Plains are adapted to these environmental factors. Periodic droughts occur at inexact, but few year, intervals. The grazing by free ranging bison, the indigenous large herbivore, has been replaced by grazing of fenced domestic stock. Fire regimes throughout human occupation of the region have been greatly influenced by human activities. Cultivation of wheat and corn also is carried out in the region.
Predicted climate changes in this region are increased …
