Late Holocene Activation History Of The Stanton Dunes, Northeastern Nebraska, Rebecca A. Puta, Paul R. Hanson, Aaron R. Young
Late Holocene Activation History Of The Stanton Dunes, Northeastern Nebraska, Rebecca A. Puta, Paul R. Hanson, Aaron R. Young
Great Plains Research: A Journal of Natural and Social Sciences
The Nebraska Sandhills have been an important resource for better understanding dune activation and the nature of prehistoric Great Plains drought events. However, until recently, few studies have focused on documenting the activation histories of smaller dune fields found along the Great Plains' eastern margin. This study focuses on the Stanton dune field, which lies about 145 km east of the Nebraska Sandhills on an alluvial terrace of the Elkhorn River in northeastern Nebraska. Sediments in the Stanton Dunes were dated with optically stimulated luminescence (OSL) to determine when these dunes were active. The ages indicate three activation periods that …
Roles Of Perceived Control And Planning In Ranch Drought Preparedness, Tonya Haigh, Cody Knutson
Roles Of Perceived Control And Planning In Ranch Drought Preparedness, Tonya Haigh, Cody Knutson
Great Plains Research: A Journal of Natural and Social Sciences
Ranchers in the Great Plains and across the United States face the threat of periodic drought. Though ranchers might minimize losses through drought-preparedness activities, many do not adequately prepare for drought, in part because of perceptions that the outcomes of drought management are not controllable. We explore how drought planning activities affect ranchers' perceptions of control and drought preparedness using the theories of planned behavior and goal attainment as guiding frameworks. Ten Great Plains ranchers who had engaged in drought management activities were interviewed about their plans. From the interviews, three activities emerged that appeared to increase ranchers' perceived control …
Perception Of Drought Hazard And Its Sociological Impacts In South-Central Nebraska, Donna L. Woudenberg, Donald A. Wilhite, Michael Hayes
Perception Of Drought Hazard And Its Sociological Impacts In South-Central Nebraska, Donna L. Woudenberg, Donald A. Wilhite, Michael Hayes
Great Plains Research: A Journal of Natural and Social Sciences
The lion's share of financial losses caused by drought is shouldered by crop and livestock producers. Producers' perceptions of and responses to drought were studied in the mid-1960s, the mid-1980s, and again in this study. Direct and indirect impacts are experienced by nonfarm businesses, communities, and individuals as well; some of those impacts have not been well researched and were integral to this project. Interviews with crop producers, livestock producers, and community members were conducted in Frontier County, NE, in late summer 2006. Producers are very perceptive of the drought hazard, a result found in the two previous studies. Adoption …
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 …
