A New Human Selenium-Containing Protein, Vadim N. Gladyshev, Kuan Teh Jeang, John C. Wootton, Dolph L. Hatfield

Vadim Gladyshev Publications

Selenium which occurs in proteins as the amino acid, selenocysteine, is essential for numerous biological processes and for human health. A prominent ⁷⁵Se-labeled protein detected in human T-cells migrated as a 15-kDa band by SDS-polyacrylamide gel electrophoresis. This protein subunit was purified and subjected to tryptic digestion and peptide sequence analyses. Sequences of tryptic peptides derived from the protein corresponded to a human placental gene sequence containing an open reading frame of 162 residues and a readthrough in-frame TGA codon. Three different peptide sequences of the 15-kDa protein corresponded to a nucleotide sequence located downstream of this codon, suggesting …

Sedimentation Of Prairie Wetlands, Robert A. Gleason, Ned H. Euliss, Jr.

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

Many wetlands in the prairie pothole region are embedded within an agricultural landscape where they are subject to varying degrees of siltation. Cultivation of wetland catchment areas has exacerbated soil erosion; wetlands in agricultural fields receive more sediment from upland areas than wetlands in grassland landscapes and hence are subject to premature filling (i.e., they have shorter topographic lives). Associated impacts from increased turbidity, sediment deposition, and increased surface water input likely have impaired natural wetland functions. Although trapping of sediments by wetlands is often cited as a water quality benefit, sediment input from agricultural fields has potential to completely …

Effects Of Atmospheric Change And Agriculture On The Biogeochemistry And Microbial Ecology Of Prairie Wetlands, Richard D. Robarts, Marley J. Waiser

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

Relatively little is known about the factors which regulate in water biogeochemical processes and food chains in prairie wetlands. Climatic warming, increased UV-radiation and agricultural activities will have interacting effects on these wetlands. We examined the effects of these processes on prairie wetland functioning and productivity with particular emphasis on production and cycling of organic carbon, especially dissolved organic carbon (DOC). Autotrophic and heterotrophic production are temperature dependent and temperature increases or decreases could affect production under more extreme climate change scenarios. DOC concentrations could decrease with increasing bacterial production and photolysis, leading to increases in UV-radiation penetration. This is …

How To Reduce Drought Risk, Cody Knutson, Mike Hayes, Tom Phillips

National Drought Mitigation Center: Faculty Publications

This guide describes a practical step-by-step process for identifying actions that can be taken to reduce potential drought-related impacts before a drought occurs. Step 1 begins with making sure that the right people are brought together and supplied with adequate data to make informed and equitable decisions during the process. Steps 2 and 3 narrow the focus of the study by identifying high priority drought-related impacts that are relevant to the user’s location or activity. Step 4 demonstrates that in order to reduce the potential for the identified impacts to occur in the future, it is necessary to understand the …

Signaling Via Camp In Fungi: Interconnections With Mitogen-Activated Protein Kinase Pathways, James Kronstad, Adriana De Maria, Deanna L. Funnell, R. David Laidlaw, Nancy Lee, Mário Moniz De Sá, Marilee Ramesh

Department of Plant Pathology: Faculty Publications

The cAMP signal transduction pathway controls a wide variety of processes in fungi. For example, considerable progress has been made in describing the involvement of cAMP pathway components in the control of morphogenesis in Saccharomyces cerevisiae, Ustilago maydis, and Magnaporthe grisea. These morphological processes include the establishment of filamentous growth in S. cerevisiae and U. maydis, and the differentiation of an appressorial infection structure in M. grisea. The discovery that appressorium formation requires cAMP signaling provides an immediate connection to fungal virulence. This connection may have broader implications among fungal pathogens because recent work indicates that …

G98-1364 Feeding Children Ages 2 To 5, H. Darlene Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide defines nutritional needs and healthy eating patterns for children ages 2 to 5.

Children Grow at Their Own Rate

Children move though growth spurts throughout childhood. Usually, a child will grow about 2 1/2 inches and gain about four or five pounds each year between the ages of 2 and 5. By 15 months old, most children have developed enough fine motor skills to feed themselves without help, if allowed to do so. Appetites vary with young children as well as adults. Parents and caregivers need to help promote a healthy pattern of eating rather than using controlling …

G98-1344 Basics Of Feeding Horses: Feeding Management, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines appropriate practices for feeding horses.

Often, nutritional management of the equine is a misunderstood topic. Successful nutritional management depends upon combining information on the nutrient requirements of different horses and their eating behaviors with the knowledge of how to best meet those requirements. Proper nutritional management is extremely critical in the horse due to the unique arrangement and anatomy of its digestive tract. Often, it is the feeding method, not feed composition, which leads to digestive disorders in horses. This NebGuide includes information on the basic, daily feeding management for horses.

Laboratory Efficacy Study With A Warfarin Bait To Control The Black-Tailed Prairie Dog, Jeff J. Mach

Vertebrate Pest Conference Proceedings: 18th (1998)

Control of the black-tailed prairie dog (Cynomys ludovicianus) is important for the reclamation of pasture ground for domestic cattle and limiting the spread of disease to humans and other wildlife. Six different concentrations of warfarin bait were fed to prairie dogs to determine mortality. Without the access to dietary vitamin K, the prairie dogs were susceptible to the warfarin bait. However, some of the prairie dogs recovered and survived the test after bait exposure was terminated. This could be due to physiological differences and the availability of fat-soluble vitamin K. The six different concentrations of warfarin consumed by …

Overview Of Wild Pig Damage In California, John Mark Frederick

Vertebrate Pest Conference Proceedings: 18th (1998)

Pigs (Sus scrofa) were first introduced to California in 1769, and European wild boars were imported to Monterey County in 1925. Descendants of the domestic swine and European wild boars have bred and formed populations of wild pigs. By the mid-1960s 15 counties had populations of wild pigs. Today 45 of California's 58 (78%) counties have reported having populations of pigs. Wild pigs can cause significant damage to farm and rangelands, livestock, natural resources, environmentally sensitive habitats, and property. There are limited estimates of damage caused by wild pigs in California. A survey was sent to all County …

Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan

Vertebrate Pest Conference Proceedings: 18th (1998)

The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of sapling lodgepole pine (Pinus contorta) during spring periods in forests of interior British Columbia and Alberta, Canada. This damage may lead to mortality and reduced growth of crop trees in managed stands. Manipulation of stand density by pre-commercial thinning to densities < 1,000 stems/ha is an effective method to lower squirrel populations and feeding damage. Lowering stand density enhances the growth of crop trees, and understory herbs and shrubs as wildlife habitat, while protecting trees from squirrel feeding. This approach has been successful in several forest ecological zones. An alternative management tool is provision of diversionary food (sunflower seed) for those stands susceptible to feeding damage, and where stand thinning has already been completed. Diversionary food can be applied aerially and is very cost effective for protecting managed stands. These techniques may be used to maintain or even enhance species diversity of small mammal communities in those forest stands requiring protection.

Manipulating Habitat Quality To Manage Vertebrate Pests, Dirk Van Vuren

Vertebrate Pest Conference Proceedings: 18th (1998)

Wildlife damage management has often emphasized density reduction through lethal means. In addition to facing increasing regulatory and social restrictions, this approach also faces ecological problems; density reduction without a concomitant decrease in carrying capacity may only stimulate density-dependent responses that quickly return population densities to pre-control levels. Consequently, habitat manipulation, either to reduce pest density or to divert the pest away from the commodity, has been pursued as an alternative. Habitat manipulation has proven effective in some circumstances and appears promising in others, but the approach is limited by our ability to identify limiting resources or highly preferred foods …

Not All Sigmodontine Rodents In The Sugarcane Fields In Coastal Veracruz, Mexico, Are Pests, Beatriz Villa C, William Lopez-Forment, Martha Villa C, Colin V. Prescott

Vertebrate Pest Conference Proceedings: 18th (1998)

Rats and mice have traditionally been considered one of the most important pests of sugarcane. However, "control" campaigns are rarely specific to the target species, and can have an affect on local wildlife, in particular nonpest rodent species. The objective of this study was to distinguish between rodent species that are pests and those that are not, and to identify patterns of food utilization by the rodents in the sugarcane crop complex. Within the crop complex, subsistence crops like maize, sorghum, rice, and bananas, which are grown alongside the sugarcane, are also subject to rodent damage. Six native rodent species …

Stable Isotope Analyses Of Tooth Annuli Reveal Temporal Dietary Records: An Example Using Stellar Sea Lions, Keith Hobson, John Sease

United States Department of Commerce: Staff Publications

Stable isotope analysis of teeth of marine mammals can provide valuable information on trophic level and source of feeding. However, the isotopic analysis of whole teeth presents only an average dietary estimate for individuals across the period of growth of that tooth. While such analyses can be valuable, particularly in the case of fossil material, in contrast, isotopic analysis of individual annuli of teeth can provide dietary information for each year of tooth growth, in some cases representing the whole of the animal's life. We measured stable-carbon isotope ratios (¹³C/¹²C) in the inorganic (hydroxyapatire) and stable-nitrogen …

Externalities From Roaming Livestock: Explaining The Demise Of The Open Range, Terence J. Centner, Ronald C. Griffin

Department of Agricultural Economics: Faculty Publications

Fence-in laws in most states require ranchers to pay for fences to keep their livestock from trespassing onto others' property. Some states, or jurisdictions within states, have a fence-out rule that requires ranchers' neighbors to pay for fences to keep livestock out. Both rules are Pareto optimal. Using a potential Pareto criterion, we show that a preference for fence-out in some areas may end as conditions change, such as increased nonranching land uses. Changed conditions may have legal consequences. Specific fence-out and fence cost-sharing provisions may be potentially Pareto inefficient and may be challenged for being unconstitutional under the due …

Why should I be concerned? Pesticides are important agricultural production tools that provide many benefits. Pesticides have been developed and used because human beings compete with insects, weeds, diseases and rodents for food, fiber and habitation. Proper management of these pests requires a responsible, systematic approach, which Integrated Pest Management (IPM) provides.
