Sorghum: A Substitute For Maize In The Nicaraguan Poultry Industry, Intsormil

INTSORMIL Impacts and Bulletins

The coffee crisis brought widespread unemployment, poverty and hunger to parts of Nicaragua. In some regions, 33% of the area’s children suffer malnutrition and child mortality claims ten out of every thousand children. Partially, in response to the coffee crisis, there is interest in promoting the poultry industry in Nicaragua, and international aid agencies are assisting Nicaraguan farmers with poultry projects. For example, the Wisconsin/Nicaragua Partners of the Americas, Inc. is currently managing a poultry project in Nicaragua called Gallinas de Patio, or backyard chickens. The project provides material and technical assistance to Nicaraguan families, enabling them to successfully raise …

Review Of Harvest For Hope: A Guide To Mindful Eating By Jane Goodall With Gary Mcavoy And Gail Hudson, Charles A. Francis

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

One of the world's preeminent experts on primate behavior, author Jane Goodall now invests her boundless energy traveling and speaking about conservation. After years of studying chimpanzees in the Gombe National Park in Tanzania, Goodall found their very existence threatened by poachers, by encroachment of farming into their habitat, and by global forces far from their wild environment. She is now on a mission to inform the public about what is wrong with our society and its impact on the planet. Harvest for Hope catalogs the problems and provides practical solutions.

Population Characteristics And Health Service Use By Latino Immigrants To Southwest Missouri, Suzanne E. Walker, Susan Dollar, Ravilldra G. Amonker

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

The rapid influx and new demographic patterns of Latino immigrants to the United States have precipitated numerous pressing issues, among them health and healthcare disparities. The relatively recent phenomenon of high Latino immigration rates to rural areas is increasingly common in the Midwest and Great Plains states, where they are drawn by the labor market. A rural setting, low socioeconomic status, and high concentrations of minorities have been shown to be closely intertwined, and such regions are often medically underserved. Such describes rural southwest Missouri, where we collected data in four counties on demographics, socioeconomic factors, healthcare perceptions, and use …

2007 Survey Of Summer Sessions Students At The University Of Nebraska-Lincoln, Paul Savory

Department of Industrial and Management Systems Engineering: Faculty Publications

During Summer 2007, UNL Summer Sessions (FlexEd) surveyed summer students to learn about their experience in taking a summer course(s). The survey results will offer confirmation of what we are doing well and will provide guidance on areas of improvement and better strategies for marketing UNL summer opportunities. A total of 227 students completed the survey. Fifteen summer classes were selected to complete a paper-based or electronic version of the survey. The classes were from three different summer sessions and used different delivery mechanisms (on-campus, studio, distance education).

Potential Of Agricultural Residues And Hay For Bioethanol Production, Ye Chen, Ratna R. Sharma-Shivappa, Deepak R. Keshwani, Chengci Chen

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Production of bioethanol from agricultural residues and hays (wheat, barley, and triticale straws, and barley, triticale, pearl millet, and sweet sorghum hays) through a series of chemical pretreatment, enzymatic hydrolysis, and fermentation processes was investigated in this study. Composition analysis suggested that the agricultural straws and hays studied contained approximately 28.62–38.58% glucan, 11.19–20.78% xylan, and 22.01–27.57% lignin, making them good candidates for bioethanol production. Chemical pretreatment with sulfuric acid or sodium hydroxide at concentrations of 0.5, 1.0, and 2.0% indicated that concentration and treatment agent play a significant role during pretreatment. After 2.0% sulfuric acid pretreatment at 121°C/15 psi for …

Comparison Of 2 Vegetation-Height Management Practices For Wildlife Control At Airports, Thomas W. Seamans, Scott C. Barras, Glen E. Bernhardt, Bradley F. Blackwell, Jonathon D. Cepek

Human–Wildlife Interactions

Vegetation-height management is a potential method to reduce bird numbers at airports. Based on studies in Europe, researchers recommended vegetation heights around 25 cm; however, preliminary studies in the United States produced conflicting results regarding the effect of tall (18 to >25 cm) vegetation on bird numbers at airports. From 1999 to 2002, we compared birds and other wildlife use of 4 short-vegetation plots (mean maximum height of 15.6 cm ± 5.1 SE and visual obstruction reading of 4.6 ± 3.0 cm) and 4 tall-vegetation plots (mean maximum height of 26.9 ± 8.4 cm and visual obstruction reading of 10.0 …

Sorghum: Nutritional Feed For U.S. And African Poultry, Intsormil

INTSORMIL Impacts and Bulletins

Grain sorghum, an important dryland crop in the Central Great Plains of the United States, is adapted to growing in areas where low and erratic rainfall and high temperatures limit production of other crops such as maize and soybeans. The United States is the largest producer of grain sorghum with 6 million acres devoted to production of this crop in 2005. Kansas produces more grain sorghum, commonly known as milo, than any other U.S. state. Kansas growers value sorghum because it performs well in many types of soils and weather. More than 80% of the sorghum produced in Kansas is …

In Vivo And In Vitro Anaerobic Mating In Candida Albicans, Raluca Dumitru, Dhammika H.M.L.P. Navarathna, Camile P. Semighini, Christian G. Elowsky, Razvan Dumitru, Daniel Dignard, Malcom Whiteway, Audrey L. Atkin, Kenneth W. Nickerson

Papers in Microbiology

Candida albicans cells of opposite mating types are thought to conjugate during infection in mammalian hosts, but paradoxically, the mating-competent opaque state is not stable at mammalian body temperatures. We found that anaerobic conditions stabilize the opaque state at 37°C, block production of farnesol, and permit in vitro mating at 37°C at efficiencies of up to 84%. Aerobically, farnesol prevents mating because it kills the opaque cells necessary for mating, and as a corollary, farnesol production is turned off in opaque cells. These in vitro observations suggest that naturally anaerobic sites, such as the efficiently colonized gastrointestinal (GI) tract, could …

Partial Characterization Of Two Moderately Halophilic Bacteria From A Kansas Salt Marsh, Aileen M. Johnson, Lance R. Thurlow, Sam R. Zwenger, Eric T. Gillock

The Prairie Naturalist

Two bacterial species were isolated from a salt marsh located on privately owned land in Russell County, Kansas. Water samples from the saIt marsh were streaked for isolation on tryptic soy agar supplemented with 12 % NaCI. Visual scanning of the plates revealed two prominent colony types. The two colony types were subcultured repeatedly until axenic cultures were obtained. 80th of these organisms were shown to be moderately halophilic. The organisms were characterized partially by fatty acid methyl ester analysis, 16S rRNA sequencing, and scanning electron microscopy. These studies revealed that the bacteria previously were unreported members of genera Marinococcus …

Family Income And Attitudes Toward Older People In China: Comparison Of Two Age Cohorts, Xiaolin Xie, Yan Ruth Xia, Xiaofan Liu

Department of Child, Youth, and Family Studies: Faculty Publications

Three hundred and five traditional college students and 159 baby boomers (40–55 years old) in China participated in the study with Kogan’s Attitude toward Old People [Kogan (1961) Journal of Abnormal and Social Psychology, 62(1), 44–54] being used. Results from ANOVA showed overall, baby boomers held more positive attitudes toward older people than college students. There was a significant interaction effect between cohorts and family income; that is, the lower family income group in both samples did not differ significantly from each other, it was in the higher family income group that difference was revealed. Baby Boomers in the …

Crop Rotation And Soil Amendment Alters Sorghum Grain Quality, Nanga Mady Kaye, Stephen C. Mason, David S. Jackson, Tom D. Galusha

Department of Food Science and Technology: Faculty Publications

Soybean [Glycine max (L.) Merr.] rotation enhances grain sorghum [Sorghum bicolor (L.) Moench] yield, but infl uence on grain quality has not been measured. The objective was to determine the effect of cropping sequence (CS) and soil amendment (SA) on grain yield and quality. Sorghum grain yield and quality, soil NO₃–N and water were measured in a rotation study in 2003 and 2004 on a Sharpsburg silty clay loam (fine, smectitic, mesic Typic Argiudoll). Cropping sequences were continuous sorghum, and sorghum rotated with non-nodulating and nodulating soybean. Soil amendments consisted of no amendment, manure (17–26 Mg …

Functional Characterization Of The Aspergillus Fumigatus Calcineurin, Márcia Eliana Da Silva Ferreira, Thorsten Heinekamp, Albert Hartl, Axel A. Brakhage, Camile P. Semighini, Steven D. Harris, Marcela Savoldi, Paula Fagundes De Gouvêa, Maria Helena De Souza Goldman, Gustavo H. Goldman

Department of Plant Pathology: Faculty Publications

Aspergillus fumigatus is an aggressive opportunistic pathogen of humans as well as a major allergen. Environmental sensing and retrieving essential nutrients from the environment are general metabolic traits associated with the growth of this saprophytic fungus. Two important mediators of calcium signals in eukaryotic cells are the Ca²⁺-binding protein calmodulin and the Ca²⁺/calmodulin-dependent phosphatase calcineurin. Calcineurin is a heterodimer that consists of a catalytic subunit A and a Ca²⁺/calmodulin binding unit. We deleted the A. fumigatus calA gene, which encodes the calcineurin A catalytic subunit, and demonstrated that this gene is not essential in …

The Relative Importance Of Different Direct Benefits In The Mate Choices Of A Field Cricket, William E. Wagner Jr., Alexandra L. Basolo

School of Biological Sciences: Faculty Publications

Discussions about the evolution of female mating preferences have often suggested that females should express multiple strong preferences when different male traits are correlated with different mating benefits, yet few studies have directly tested this hypothesis by comparing the strength of female preferences for male traits known to be correlated with different benefits. In the variable field cricket, Gryllus lineaticeps, females receive fecundity and fertility benefits from mating with males with higher chirp rates and life-span benefits from mating with males with longer chirp durations. Although females prefer higher chirp rates and longer chirp durations when the other trait …

The Cost Of Reproduction: The Devil In The Details, Lawrence G. Harshman, Anthony J. Zera

Anthony Zera Publications

The cost of reproduction is of fundamental importance in life-history evolution. However, our understanding of its mechanistic basis has been limited by a lack of detailed functional information at all biological levels. Here, we identify, evaluate and integrate recent studies in five areas examining the proximate mechanisms underlying the cost of reproduction. Rather than being alternate explanations, hormonal regulation and intermediary metabolism act in concert and have an overarching influence in shaping the cost of reproduction. Immune function is compromised by reproduction, as is resistance to environmental stress. These studies not only provide new information about mechanisms that comprise “the …

Oral Rabies Vaccine (Orv) Bait Uptake By Captive Striped Skunks, Susan M. Jojola, Stacie J. Robinson, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Aerial delivery of oral rabies vaccine (ORV) baits has proven effective in large-scale efforts to immunize wildlife against rabies, and in North America this strategy currently is being used to immunize foxes (Urocyon cinereoargenteus and Vulpes vulpes), raccoons (Procyon lotor), and coyotes (Canis latrans). Skunks are also a major reservoir and vector of rabies, but at present oral vaccines for use in skunks are not licensed. Furthermore, given differences in morphology (smaller jaws) and behavior (food handling and consumption), it is unknown if baits currently used in ORV campaigns would be effective for skunks. …

Greater Diversity Of Shiga Toxin-Encoding Bacteriophage Insertion Sites Among Escherichia Coli O157:H7 Isolates From Cattle Than In Those From Humans, Thomas E. Besser, Nurmohammad Shaikh, Nicholas J. Holt, Phillip I. Tarr, Michael E. Konkel, Preeti Malik-Kale, Coilin W. Walsh, Thomas S. Whittam, James L. Bono

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

E. coli O157:H7, a zoonotic human pathogen for which domestic cattle are a reservoir host, produces a Shiga toxin(s) (Stx) encoded by bacteriophages. Chromosomal insertion sites of these bacteriophages define three principal genotypes (clusters 1 to 3) among clinical isolates of E. coliO157:H7. Stx-encoding bacteriophage insertion site genotypes of 282 clinical and 80 bovine isolates were evaluated. A total of 268 (95.0%) of the clinical isolates, but only 41 (51.3%) of the bovine isolates, belonged to cluster 1, 2, or 3 (P < 0.001). Thirteen additional genotypes were identified in isolates from both cattle and humans (four genotypes), from only cattle (seven genotypes), or from only humans (two genotypes). Two other markers previously associated with isolates from cattle or with clinical isolates showed similar associations with genotype groups within bovine isolates; the tir allele sp-1 and the Q_933W allele were under- and overrepresented, respectively, among cluster 1 to …

Mountain Beaver Home Ranges, Habitat Use, And Population Dynamics In Washington, W. M. Arjo, R. E. Huenefeld, D. L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

The mountain beaver (Aplodontia rufa (Rafinesque, 1817)), endemic to western North America, is the only extant member of the family Aplodontidae. Limited information on movements and habitat use throughout the species' range is available. We radio-collared 41 mountain beavers to determine home ranges, dispersal, habitat use, and population densities on two managed forest sites in coastal Washington. Both sites were recently harvested for timber. The Donovan site (16.6 ha) was treated with herbicide before seedling planting and the Sylvia site (8.9 ha) was not treated. Mountain beaver home ranges (Donovan: 4.18 ± 0.81 ha; Sylvia: 1.39 ± 0.4 ha) …

Influence Of Buffalograss Management Practices On Western Chinch Bug And Its Beneficial Arthropods, Jeffrey Carstens, Tiffany Heng-Moss, Frederick P. Baxendale, Roch E. Gaussoin, Kevin Frank, Linda J. Young

Department of Entomology: Faculty Publications

A 2-yr study was conducted to document the influence of selected buffalograss, Buchloe dactyloides (Nuttall) Engelmann, management practices (three mowing heights and five nitrogen levels) on the seasonal abundance of the western chinch bug, Blissus occiduus Barber (Heteroptera: Lygaeidae), and its beneficial arthropods. Vacuum, pitfall, and sticky traps samples were collected every 14 d from the middle of May through October from western chinch bug-resistant (‘Prestige’) and -susceptible (‘378’) buffalograss management plots. In total, 27,374 and 108,908 western chinch bugs were collected in vacuum and pitfall traps, respectively. More than 78% of all western chinch bugs were collected from the …
