INTSORMIL Impacts and Bulletins

Sorghum and pearl millet are the most important cereal crops in West Africa where they provide 70% of total cereal production that provide the major complements in the diets of people in the region. Research progress in the improvement of sorghum and millet is, therefore, of vital importance to the well being of people in West Africa. The Hybrid Sorghum and Pearl Millet Seed Workshop in West Africa is the culmination of the research and development effort by the Institut National de Recherches Agronomiques du Niger (INRAN) , the International Sorghum and Millet Collaborative Research Support Program (INTSORMIL), and the …

Influence Of Seismic Surveys On Western Gray Whales Off Sakhalin Island, Russia In 2001, David W. Weller, Yulia V. Ivashchenko, Grigory A. Tsidulko, Alexander M. Burdin, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Western gray whales (Eschrichtius robustus) aggregate off the northeastern coast of Sakhalin Island, Russia during summer-autumn to feed on benthic and near-benthic prey. During summer 2001, 3D seismic surveys were conducted during a six-week period in known gray whale foraging areas off Sakhalin Island. To test the hypothesis that the distribution of gray whales on the feeding ground would shift away from nearby seismic surveying, we examined the number of whales and number of pods (dependent variables) sighted during systematic scans in relation to three independent variables (i.e. preseismic, seismic, post-seismic). Results showed the main effect of condition …

Latino Families In The Perinatal Period: Cultural Issues In Dealing With The Health-Care System, J. Martin Maldonado-Duran, Maria Manguia-Wellman, Sari Lubin, Teresa Lartigue

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

Migration of young Latinos and Latinas has increased in many towns in the Midwest. These young people will experience the perinatal period in a new cultural environment. We focus on the interface between families of Latino origin and the Midwest health-care system, particularly in the care of the pregnant woman or couple and in the care of the infant. Issues of culture are central in the perinatal period, and often the staff in health-care centers is not aware of the importance of several traditional and "folk" health-care beliefs in this period. These beliefs impact the care of the pregnant woman, …

Mexican-Descent Latinas’ Compliance With Cervical Cancer Screening Guidelines, Evelinn A. Borrayo, Awilda Reyes

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

High mortality from invasive cervical cancer among Mexican-descent Latinas living in the Great Plains could be substantially reduced if they would utilize screening procedures regularly. To understand possible influential factors on their screening behaviors, we investigated which variables differentiate women age 50 and older who are most compliant with cervical cancer screening guidelines from those who are less compliant. Of 184 women surveyed, 100 were compliant with a yearly Pap smear while 84 were not compliant. Discriminant function analysis revealed that, apart from the significance of sociodemographic factors and acculturation, women who were most compliant significantly received more health-care provider …

Stable Replication Of Papillomavirus Genomes In Saccharomyces Cerevisiae, Peter C. Angeletti, Kitai Kim, Fiona J. Fernandes, Paul F. Lambert

Nebraska Center for Virology: Faculty Publications

Papillomaviruses normally replicate in stratified squamous epithelial tissues of their mammalian hosts, in which the viral genome is found as a nuclear plasmid. Two viral proteins, E1, a helicase, and E2, a transcriptional activator and plasmid maintenance factor, are known to contribute to the episomal replication of the viral genome. Recently, our laboratory discovered that papillomaviruses can also replicate in an E1-independent manner in mammalian cells (K. Kim and P. F. Lambert, Virology, in press; K. Kim and P. F. Lambert, submitted for publication). In this study, we describe experiments investigating the capacity of the human papillomavirus type 16 (HPV16) …

Nutria (Myocaster Coypus) In Louisiana, John Baroch, Mark Hafner, Tommy L. Brown, Jeff J. Mach, Richard M. Poché

Other Publications in Wildlife Management

Biology and Natural History of the Nutria, With Special Reference to Nutria in Louisiana
The nutria or coypu (Myocastor coypus) is a rodent native to South America that has been introduced almost worldwide since the early 1900’s, originally with the intent of fur farming in many cases. The nutria is a large (over 6 kg), semi-aquatic rodent with a voracious appetite and high reproductive potential. Nutria became established in the Louisiana wetlands in the 1930’s. The habitat proved to be ideal and populations exploded, reaching an estimated 20 million animals in less than 20 years. Trapping of nutria …

Report Of Animal Bones From Tjarnargata 3c, Reykjavík, Iceland, Sophia Perdikaris, Colin Amundsen, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

Executive Summary

During rescue excavations in downtown Reykjavík in 1999 nearly 100 kg of well-preserved animal bone was recovered in investigations at Tjarnargata 3 C by Fornleifastofnun Islands (FSÍ) directed by Mjöll Snaesdóttir. This bone collection (or archaeofauna) was largely sieved (4 mm and 1 mm mesh wet screen) and represents one of the largest archaeofauna recovered from Iceland to date. Analysis was carried out at City University of New York’s Northern Science & Education Center’s two zooarchaeology laboratories at Brooklyn College and Hunter College in 2000-01. The analyzed bone materials were returned for long term curation at the National …

Rocky Mountain Wolf Recovery 2002 Annual Report

Rocky Mountain Wolf Recovery: Annual Reports

Wolves (Canis lupus) in the Northern Rocky Mountain states (Idaho, Montana and Wyoming) continue to increase in distribution and numbers (Figures 1, 5). Estimates of wolf numbers at the end of 2002 were 284 wolves in the Central Idaho Recovery Area, 271 in the Greater Yellowstone Recovery Area, and 108 in the Northwest Montana Recovery Area for a total of 663 (Figure 1, Table 4a). By state boundaries, there were an estimated 263 wolves in the state of Idaho, 217 in Wyoming and 183 in Montana (Table 4b). Of approximately 80 groups of two or more wolves, 43 …

Size Of Beef Cows: Early Ideas, New Developments, Jesus Arango, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Optimum size for beef cattle is debated among researchers, cattle breeders and producers. Cattle vary widely in body size but optimal size depends on the production system. Selection has placed emphasis on growth, favoring leaner and faster growing cattle. This trend has led to an increase immature size of cattle that may not necessarily be advantageous. Many research results have indicated that there is not a direct relationship between size and efficiency in beef production if each biological type of cattle is managed according to its nutrient requirements and management practices within the beef industry in the world, however, a …

Seasonal Dynamics Of Prairie Sandreed Rhizome Development, Patrick E. Reece, Jennifer S. Nixon, Lowell E. Moser, Steven S. Waller

Department of Agronomy and Horticulture: Faculty Publications

Multiple generations of rhizome-connected tillers stabilize soils and produce measurable amounts of herbage on sandy rangeland throughout the world. However, little is known about the dynamics of rhizome development in these clonal plant species. Seasonal relationships between foliar characteristics and rhizomes of prairie sandreed [Calamovilfa longifolia (Hook) Scribn.] were examined on sands range sites at 30-day intervals from May through September 1989 and 1990 at the University of Nebraska, Panhandle Experimental Range near Scottsbluff. Quadrats were excavated each year from two, 5 x 5 Latin Square macroplots in each of 2 grazing histories, long-term rest or current-year deferment. Under …

Avian Repellents, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

The use of repellents to protect crops from birds has a long history. Early European settlers in eastern North America observed that native Americans used an extract of Veratrum spp. to protect corn seeds from avian depredators: ‘‘Then when the starlings, crows, or other birds, pick up or pluck out the grains of corn, their heads grow delirious, and they fall, which so frightens the rest that they never venture on the field again. When those which have tasted the grains recover, they leave the field, and are no more tempted to visit it again’’ (1).

Repellents move birds from …

Vegetation Management Approaches For Reducing Wildlife-Aircraft Collisions, Scott C. Barras, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose safety risks to aircraft and cost civil aviation over $390 million annually in the USA. We reviewed the results of prior studies to summarize the vegetation management techniques that have proven effective for wildlife strike reduction or have shown potential for achieving the same goal. Habitat components that may affect wildlife use of airports include food, cover, water, and loafing areas. Improperly managed natural and ornamental vegetation on airports can be important attractants for wildlife that pose strike hazards. However, effective vegetation management can reduce these hazards. Maintaining tall herbaceous vegetation may reduce the availability …

Birds In Pest Management, M L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

As human activity encroaches on wildlife habitats and natural food sources become increasingly scarce, it is no wonder that birds turn to habitats such as crop fields and aquaculture ponds. Where else can large flocks of birds find sufficient, nutritious, readily available food? Agricultural crops create ideal foraging sites for gregarious bird species, and virtually everything that humans grow or raise for food is subject to some level of bird damage. For most farmers, bird damage is a fact of life, but not a major concern. The unlucky few producers for whom depredations are severe, however, do incur substantial financial …

Behavioral And Ecological Considerations For Managing Bird Damage To Cultivated Fruit, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

Many bird species eat fruits and, likewise, many plant species are dependent on birds for the dispersal of seeds. Through cultivation and selective breeding, attributes of wild fruit have been changed to make fruit more palatable to humans. For example, cultivated species bear fruits that are often thinner-skinned. are more succulent, have fewer seeds and are easier to pick than non-cultivated species. These same changes, however, have also increased the attractiveness of fruit to avian consumers. Ecological relationships that have developed across evolutionary time between wild plants and frugivores become emphasized by the introduction of cultivated fruits that have been …

Displacement Of Escherichia Coli O157:H7 From Rumen Medium Containing Prebiotic Sugars, Albane De Vaux, Mark Morrison, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

A fed-batch, anaerobic culture system was developed to assess the behavior of Escherichia coli O157:H7 in a rumen-like environment. Fermentation medium consisted of either 50% (vol/vol) raw or sterile rumen fluid and 50% phosphate buffer. Additional rumen fluid was added twice per day, and samples were removed three times per day to simulate the exiting of digesta and microbes from the rumen environment under typical feeding regimens. With both types of medium, anaerobic and enteric bacteria reached 10¹⁰ and 10⁴ cells/ml, respectively, and were maintained at these levels for at least 5 days. When a rifampin-resistant strain of …

Adenylyl Cyclase Functions Downstream Of The Gα Protein Gpa1 And Controls Mating And Pathogenicity Of Cryptococcus Neoformans, J. Andrew Alspaugh, Read Pukkila-Worley, Toshiaki Harashima, Lora M. Cavallo, Deanna L. Funnell, Gary M. Cox, John R. Perfect, James W. Kronstad, Joseph Heitman

Department of Plant Pathology: Faculty Publications

The signaling molecule cyclic AMP (cAMP) is a ubiquitous second messenger that enables cells to detect and respond to extracellular signals. cAMP is generated by the enzyme adenylyl cyclase, which is activated or inhibited by the Gα subunits of heterotrimeric G proteins in response to ligand-activated G-protein-coupled receptors. Here we identified the unique gene (CAC1) encoding adenylyl cyclase in the opportunistic fungal pathogen Cryptococcus neoformans. The CAC1 gene was disrupted by transformation and homologous recombination. In stark contrast to the situation for Saccharomyces cerevisiae, in which adenylyl cyclase is essential, C. neoformans cac1 mutant strains were viable and …

Genetic Parameters And Responses Of Linear Type, Yield Traits, And Somatic Cell Scores To Divergent Selection For Predicted Transmitting Ability For Type In Holsteins, B. J. Degroot, Jeffrey F. Keown, L. Dale Van Vleck, Erin L. Marotz

Department of Animal Science: Faculty Publications

The objective was to examine the direct and correlated responses of linear type, yield traits, and somatic cell scores (SCS) to divergent selection for predicted transmitting ability for type (PTAT) in Holsteins, while maintaining selection for yield traits across lines. For four generations, one-half of the University of Nebraska research Holstein herd was bred to Holstein sires with PTAT -1.50 and the other half to sires with PTAT - 1.25, with nearly equal predicted transmitting abilities for yield traits for both groups. Estimates of genetic and residual correlations and heritabilities were obtained from REML estimates of (co)variance components. Model for …

All these things were designed to help them make changes when they return home. The following are …

Intsormil 2002 Annual Report, John M. Yohe, Thomas Crawford Jr., Kimberly Jones, Dorothy Stoner

INTSORMIL Impacts and Bulletins

The global community confronts an enonnous task of stimulating economic growth in rural areas where 75% of the very poor (90% in Africa) currently live and ensuring the nutritional security of a world popUlation that is growing in size and evolving in consumption patterns without intensifying environmental degradation, social security, or adverse consequences for human health. This challenge is not only great but it is also urgent. Today, access to food, sufficient, safe, and nutritious food, is the primary problem for nearly 800 million chronically undernourished people. Unless we act now, the next few decades will almost certainly find us …

Detecting Stress In Animals, Sharon Durham, Ted H. Elsasser

Agricultural Research Magazine

When people get stressed, they seek relief in many ways. Some exercise, some practice specific breathing techniques, and some eat chocolate. Farm animals become stressed, too. In domesticated food animals, stress can affect meat quality, milk production, and general health. But animal stress must often be intuited from clues such as lower-than-anticipated weights and increased illness.

Certain stressful events can be anticipated, for example, birth and weaning. But how do you know if an animal is stressed for some other reason? Ted H. Elsasser of ARS’ Growth Biology Laboratory in Beltsville, Maryland, is investigating nitrated protein as a biomarker of …

Speeding Up Breeding Of Superior Plants, Judy St. John

That oatmeal you ate for breakfast this morning is loaded with healthful compounds known as antioxidants. They help to protect your body from damage caused by molecules known as free radicals. Oats, for instance, are rich in the antioxidants alpha-tocopherol and alpha-tocotrienol.

But what if tomorrow’s oats could provide even more of these health-imparting compounds? That’s a goal of ARS oat researchers at laboratories in several states. Aiding this research is an invaluable tool of modern biotechnology. Known as biomolecular markers, gene markers, or DNA markers, these pieces of genetic material are signposts or clues. They are telltale indicators that, …
