Upland Rice And Allelopathy, N. K. Fageria, V. C. Baligar

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chemical interactions. The level of phytotoxicity of allelochemicals is influenced by abiotic and biotic soil factors. Adopting suitable management strategies in crop rotation can reduce or eliminate allelochemicals phytotoxicity. Rice yields can be improved by growing …

Evaluation Of Resistance Screening Methods For Sclerotinia Stem Rot Of Soybean And Dry Bean, Linda S. Kull, Tri D. Vuong, Kris S. Powers, Kent M. Eskridge, James R. Steadman, Glen L. Hartman

Department of Plant Pathology: Faculty Publications

Three methods to identify levels of resistance to Sclerotinia sclerotiorum in soybean (Glycine max) and dry bean (Phaseolus vulgaris) were compared using multiple data analyses. The three methods were mycelial plug inoculations of cotyledons, cut stems, and detached leaves. Six S. sclerotiorum isolates of known relative aggressiveness were inoculated on each of three soybean and dry bean cultivars with varied response to S. sclerotiorum. For soybean, all three inoculation methods accurately identified isolate aggressiveness irrespective of cultivar, but identification of susceptible and partially resistant soybean cultivars was influenced by isolate. For dry bean, the cotyledon and cut …

Community Dynamics Of An Ecotonal Forest-Prairie Interface In Northeastern Kansas, Elizabeth Hane, Steven Hamburg

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Climate change models predict that ecotones, which are boundaries between two biomes, are likely to be the first place we see the effects of climate change. However, very little baseline data exist for these areas and their current community structure. In order to better understand the community dynamics of an ecotonal forest, a 2.2 ha 60- year-old upland forest in northeastern Kansas was monitored for 10 years. This oak-hickory forest at the ecotone with the tallgrass prairie biome is growing more slowly than other forests of similar species composition farther east, possibly due to lower levels of available soil moisture …

Challenges, Strategies, And Tools For Research Scientists: Using Web-Based Information Resources, Danielle Bodrero Hoggan

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Scientists face many challenges in harnessing web-based resources. Information overload, misinformation, fees, poorly designed navigation, and loss of browsability all hamper the scientist searcher. In addition, many scientists rely on only one or two databases and often miss unique information that is available through other sources. Librarians can team up with scientists to develop strategies to overcome the challenges of web-based information. For example, a librarian can teach effective information seeking techniques, including how to use controlled vocabularies, how to evaluate information on the web, and how to complement web-based resources with print resources. Librarians can also help scientists to …

The Improvement Of Water And Water-Dependent Resources Under The Great Lakes Charter Annex, Sandi Zellmer, David Gecas, Kori Anne Mann

Nebraska College of Law: Faculty Publications

The Governors of 8 states and Premiers of 2 Canadian provinces signed a supplementary agreement to the Great Lakes Charter on June 18, 2001. This agreement, known as the Annex or Annex 2001, established principles for a new decision making framework for reviewing proposed withdrawals of Great Lakes water. Annex 2001 is the first step toward a set of binding water management agreements to be negotiated by June 2004. Directive 3 of the Annex provides that proposals to withdraw water will not be approved unless they will produce "an improvement to the waters and water dependent natural resources of the …

Habitat Conservation For Birds In The Mississippi Headwaters/Tallgrass Prairie Ecosystem, Rolf Koford, Heidi Stallman

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Land management agencies need to plan and prioritize their activities to best use limited resources. To implement ecosystem management, the US Fish and Wildlife Service has defined watershed-based planning units, such as the Mississippi Headwaters/Tallgrass Prairie Ecosystem. To identify important habitats for migratory birds in this ecosystem, we ranked habitats according to their importance for breeding birds of conservation concern, using rankings of the birds' conservation priority within this ecosystem. Grasslands and wetlands were the highest ranked habitats because 12 (46%) and 9 (25%), respectively, of the species breeding in these habitats had "Partners in Flight" scores greater than 19 …

Assessing Vulnerability To Agricultural Drought: A Nebraska Case Study, Olga V. Wilhelmi, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

Recent drought events in the United States and the magnitude of drought losses indicate the continuing vulnerability of the country to drought. Until recently, drought management in many states, including Nebraska, has been largely response oriented with little or no attention to mitigation and preparedness. In 1998, Nebraska began to revise its drought plan in order to place more emphasis on mitigation. One of the main aspects of drought mitigation and planning is the assessment of who and what is vulnerable and why. This paper presents a method for spatial, Geographic Information Systems-based assessment of agricultural drought vulnerability in Nebraska. …

Review Of The Background And Application Of Triolein-Containing Semipermeable Membrane Devices In Aquatic Environmental Study, Yibing Lu, Zijian Wang, James Huckins

United States Geological Survey: Staff Publications

This paper briefly reviews research on passive in situ samplers for aquatic environments but focuses on the development and application of the triolein-containing semipermeable membrane device in aquatic environmental monitoring. Special attention is paid to the calibration of the devices, quality control issues, and its potential uses in environmental assessments of aquatic contaminants. Also, the suitability of the technique for incorporation with selected bioassays is examined.

Effects Of Management Practices On Grassland Birds: Wilson’S Phalarope, Jill A. Dechant, Douglas H. Johnson, Lawrence D. Igl, Christopher M. Goldade, Amy L. Zimmerman, Betty R. Euliss

United States Geological Survey: Effects of Management Practices on Grassland Birds

Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 4,000 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which …

Effective Integration Of Human Factors Into Hse Management Systems, Denise B. Mccafferty, Clifford C. Baker, Kevin P. Mcsweeney, Rodger Holdsworth

United States Department of Transportation: Publications

It is common that offshore operating and drilling companies have policies, procedures, and practices that address Health, Safety, and Environmental (HSE) issues. It is less likely that such organizations will explicitly address (through written requirements) human factors (HF) concerns. Regardless, both HSE and HF are concerned with the same objectives: protecting people, property, and the natural environment from damage. The methods of each examine the job performed by the human, and compare work requirements to the design of hardware, software, and paper systems to allow safe and efficient performance. The perspectives of both disciplines are generally “user-centered” and act as …

Assemblages Of Breeding Birds As Indicators Of Grassland Condition, Sharon Freshman Browder, Douglas H. Johnson, I. J. Ball

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We developed a measure of biological integrity for grasslands (GI) based on the most influential habitat types in the Prairie Pothole Region of North Dakota. GI is based on proportions of habitat types and the relationships of these habitat types to breeding birds. Habitat types were identified by digital aerial photography, verified on the ground, and quantified using GIS. We then developed an index to GI based on the presence or abundance of breeding bird species. Species abundance data were obtained from 3 min roadside point counts at 889 points in 44, 4050 ha study plots over a 2-year period. …

The Importance Of Replication In Wildlife Research, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wildlife ecology and management studies have been widely criticized for deficiencies in design or analysis. Manipulative experiments-with controls, randomization, and replication in space and time-provide powerful ways of learning about natural systems and establishing causal relationships, but such studies are rare in our field. Observational studies and sample surveys are more common; they also require appropriate design and analysis. More important than the design and analysis of individual studies is metareplication: replication of entire studies. Similar conclusions obtained from studies of the same phenomenon conducted under widely differing conditions will give us greater confidence in the generality of those findings …
