"Trade Reform, The Key To The Future Of U.S. Farming", Clayton K. Yeutter
"Trade Reform, The Key To The Future Of U.S. Farming", Clayton K. Yeutter
Clayton K. Yeutter, United States Secretary of Agriculture: Papers
I have been asked innumerable times why world agricultural trade reform is so important to U.S. farmers. Some of the people doing the asking are often afraid of what such reform might mean to U.S. agriculture. A question I occasionally ask back is, "What is there to fear?" If we are the efficient agricultural producers we say we are -- and I believe we are - then the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) offers American farmers an unprecedented opportunity to gain market share in the growing world markets for food. American agriculture has not …

The American Market For Indian Textiles, 1785-1820: In The Twilight Of Traditional Cloth Manufacture, Susan S. Bean
The American Market For Indian Textiles, 1785-1820: In The Twilight Of Traditional Cloth Manufacture, Susan S. Bean
Textile Society of America: Symposium Proceedings
A brisk trade in Indian cloth developed soon after the end of the American War of Independence in 1783 and continued to flourish until Congress enacted a prohibitive tariff in 1816 to protect the nascent U.S. textile manufacturing industry. For the period 1795-1805, U.S. trade with India well exceeded trade with all European nations combined for all commodities (Furber 1938:258). Cloth was the centerpiece of this trade: The piece goods imported in 1804-05, for instance, were about three times the value of all other goods from India, chiefly sugar, indigo, ginger, and a variety of spices and drugs (Bhagat 1970:42). …
Textiles In Trade In West Africa, Brigitte Menzel
Textiles In Trade In West Africa, Brigitte Menzel
Textile Society of America: Symposium Proceedings
Textiles in Africa since some time have become a topic of research, much of which is focused on aspects of art. The at least equally important economic aspects (production, consumption, and trade) are still rather neglected.
When doing field research in West Africa it is impossible to overlook the fact that most of the textiles in use could not have been produced locally. This applies not only to the colorful printed cottons but as well to handmade textiles.
In Asante (Ghana) I found woolen fabrics, which obviously were hand-woven but must have come from somewhere else as sheep and goats …
Environmental Influences On Soil Macroarthropod Behavior In Agricultural Systems, Michael G. Villani, Robert J. Wright
Environmental Influences On Soil Macroarthropod Behavior In Agricultural Systems, Michael G. Villani, Robert J. Wright
Department of Entomology: Faculty Publications
Many basic and applied studies in insect ecology have focused on the proximate and ultimate responses of insect populations to their physical and chemical environment (2, 15, 21, 27, 32, 74, 82, 111, 112). From an economic perspective, macro- and microclimatic factors can influence the stress that insect populations inflict on plants and the efficacy of management tactics. For above-ground insects, the mechanisms of behavioral response to environmental factors are often observable, if not always apparent to the researcher. However, this is not typically the situation with soil insects. As a result, field studies of soil insects often quantify only …
Intramuscular Collagen And Serum Hydroxyproline As Related To Implanted Testosterone, Dihydrotestosterone And Estradiol-17Β In Growing Wethers, L. F. Miller, M. D. Judge, B. D. Schanbacher
Intramuscular Collagen And Serum Hydroxyproline As Related To Implanted Testosterone, Dihydrotestosterone And Estradiol-17Β In Growing Wethers, L. F. Miller, M. D. Judge, B. D. Schanbacher
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Relationships of implanted testosterone, dihydrotestosterone and estradiol-17β to collagen degradation and intramuscular collagen concentration and stability were determined. Intramuscular collagen content, solubility and shrinkage temperature and serum hydroxyproline were analyzed in groups of six rams, wethers, and wethers implanted with various levels of testosterone or dihydrotestosterone (Exp. 1) and groups of 10 rams, wethers and wethers implanted with estradiol-17β, dihydrotestosterone or a combination of these two steroids (Exp. 2). Intramuscular collagen content in both experiments was higher (P < .05) in muscles of rams than in muscles of wethers. Administration of the highest level of testosterone to wethers raised (P < .05) total and insoluble intramuscular collagen to concentrations noted in rams. Administration of the testosterone metabolite, dihydrotestosterone, to wethers had no effect on intramuscular collagen. Administration of estradiol-17β to wethers tended to raise concentrations of intramuscular collagen so that they were no longer lower (P < .05) than those in rams. Collagen stability as measured by solubility and thermal shrinkage temperature did not differ among rams, wethers or implanted wethers (P > .05). Increases in collagen accretion due to hormone administration were observed to be the result of increases in the insoluble portion of …
Comparative Attraction Of Four Different Fiberglass Traps To Various Age And Sex Classes Of Stable Fly (Diptera: Muscidae) Adults, Jerome Hogsette, Joseph Ruff
Comparative Attraction Of Four Different Fiberglass Traps To Various Age And Sex Classes Of Stable Fly (Diptera: Muscidae) Adults, Jerome Hogsette, Joseph Ruff
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
An Alsynite cylinder trap and three different Williams cross-configuration traps with three adhesives were compared to determine their relative attraction to stable fly, Stomoxys calcitrans (L.), adults. Williams traps coated with Olson Sticky Stuff performed as well as Williams traps coated with Tack Trap, thus allowing fly samples collected with either adhesive to be compared. The cylinder trap captured fewer total flies,but more flies per cm2 than any of the Williams traps. Sex ratio of flies captured on the cylinder trap was 50:50, while the three Williams traps captured predominantly males. The cylinder trap captured a larger percentage of …
Concentrations Of Insulin-Like Growth Factor-I In Blood And Ovarian Follicular Fluid Of Cattle Selected For Twins, S. E. Echternkamp, L. J. Spicer, K. E. Gregory, S. F. Canning, J. M. Hammond
Concentrations Of Insulin-Like Growth Factor-I In Blood And Ovarian Follicular Fluid Of Cattle Selected For Twins, S. E. Echternkamp, L. J. Spicer, K. E. Gregory, S. F. Canning, J. M. Hammond
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Recent studies have implicated insulin-like growth factor I (IGF-I) as an intraovarian regulator of follicular growth and differentiation. Therefore, we investigated the possibility that cattle selected for twin births may have increased concentrations of IGF-I within the ovarian follicle and(or) in peripheral blood. The estrous cycles of 14 cows with histories of producing twins and 12 control monotocous cows were synchronized with 35 mg of prostaglandin F2α (PGF2α). Blood and follicular fluid were collected 48-50 h post-administration of PGF2α. (follicular phase of the estrous cycle). Concentrations of IGF-I were measured by RJA after acid-ethanol treatment …

Identification Of Single Meloidogyne Juveniles By Polymerase Chain Reaction Amplification Of Mitochondrial Dna, T. S. Harris, L. J. Sandall, Thomas O. Powers
Department of Plant Pathology: Faculty Publications
Polymerase chain reaction (PCR) was used to amplify a specific 1.8-kb sequence of mitochondrial DNA from single juveniles and eggs from 17 populations of Meloidogyne incognita, M. hapla, M. javanica, and M. arenaria. Approximately 2 μg amplified product were produced per reaction. Restriction digestion of the amplified product with HinfI permitted discrimination of clonal lineages of the four species. Meloidogyne javanica, however, could not be separated from M. hapla by the enzymes used in these experiments. Various amplification conditions and nematode lysis procedures were examined in order to optimize the speed and quality of …

Adsorption Of Bromide Tracers Onto Sediment, John E. Gilley, S. C. Finkner, John W. Doran, E. R. Kottwitz
Adsorption Of Bromide Tracers Onto Sediment, John E. Gilley, S. C. Finkner, John W. Doran, E. R. Kottwitz
Department of Agricultural and Biological Systems Engineering: Faculty Publications
Information concerning hydraulic parameters on upland areas could be greatly expanded through the use of tracing techniques. If bromide is used as a tracer, adsorption of bromide onto sediment may be of concern. Therefore, a laboratory study was conducted to identify the effects of sediment content and initial bromide concentration on adsorption of bromide for selected soils.
When bromide solutions were used within the appropriate instrument measurement range, neither soil texture, liming, nor sediment content were found to significantly affect adsorption of bromide. In contrast to systems using fluorescent dyes, correction factors for estimating adsorption of bromide are unnecessary. Since …

Spatial Memory In Seed-Caching Corvids, Alan Kamil, Russell P. Balda
Papers in Behavior in Biological Sciences
Our purpose in this article is to review the results of our studies of the mechanisms underlying cache recovery by members of the crow, jay, and nutcracker family. In this research program, we have combined psychological and ecological approaches to the study of memory, and the results demonstrate the utility of this interdisciplinary strategy. Unlike most psychological research on learning and memory, this research program originated in the study of how a particular species solves a particular ecological problem. It serves as an example of how natural history and ecology can provide the starting point for a research program that …
Relationships Between Blood Parasites, Mating Success And Phenotypic Cues In Male Sage Grouse Centrocercus Urophasianus, Robert M. Gibson
Relationships Between Blood Parasites, Mating Success And Phenotypic Cues In Male Sage Grouse Centrocercus Urophasianus, Robert M. Gibson
School of Biological Sciences: Faculty Publications
In lek breeding Sage Grouse Centrocercus urophasianus in eastern California, male mating success is strongly correlated with individual differences in lek attendance, and in the rate and acoustic quality of courtship display, suggesting that these provide cues by which females choose mates. Increased lek attendance and high display rates also associated with elevated metabolic expenditure. This paper examines the hypothesis that the ability to commit energy to display is related to the incidence of blood parasites. A single hematozoan genus, Haemoproteus, was found in 37.5% of 184 Sage Grouse sampled over a five year period. Parasitism varied across years and …

Cuticular Ridge Pattern In Ostertagia Gruehneri And Ostertagia Arctica (Nematoda: Trichostrongyloidea) From Caribou, Rangifer Tarandus, J. Ralph Lichtenfels, P. A. Pilitt, M. Fruetel
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Two species of medium stomach worms are common parasites of the caribou, Rangifer tarandus. The two species, Ostertagia gruehneri Skrjabin, 1929, and O. arctica Mitzkewitzsch, 1929, differ so markedly in morphology of the spicules and genital cone that many nematode systematists place them in different genera. Recent studies of similar pairs of species parasitic in other ruminants have provided evidence that such pairs of species may be morphotypes of one species. The two species from caribou are redescribed with emphasis on the pattern of surface cuticular ridges and the structure of the esophagus, characters considered useful for distinguishing species …

Some Helminth Parasites Of Dunlin (Calidris Alpina) And Western Willet (Catoptrophorus Semipalmatus Inornatus) From California, Hilda Lei Ching
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Dunlins and western willets were collected on their winter feeding grounds at Bodega Bay and Bolinas Lagoon, California, during 1986. Six digeneans, eight cestodes, two acanthocephalans, and a new nematode were found in dunlins. Seven digeneans, two cestodes, one acanthocephalan, and the new nematode were found in western willets; four helminths including the new roundworm were common to dunlins. Thominx cecumitis sp. n. differs from other capillarid nematodes with a spinous spicule-sheath in having a short, globular vulvar appendage, peanut-shapcd eggs, a cuticular ball at the posterior tip of the body, narrow lateral alae, and a cuticular genital bursa.

Helminth Parasitism In Martens (Martes Americana) And Ermines (Mustela Erminea) From Washington, With Comments On The Distribution Of Trichinella Spiralis, Eric P. Hoberg, Keith B. Aubry, J. David Brittell
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Helminths are reported for the first time from ermines (Mustela erminea) and martens (Martes americana) in Washington, USA. Among 22 adult ermines, 41% were infected by one or more of five species (Taenia mustelae, Alaria mustelae, Molineus patens, M. mustelae, and Trichinella spiralis). Among 78 adult martens from three geographic localities, the prevalence was 83%. Nine species were identified (Mesocestoides sp., T. mustelae and T. martis americana, Euryhelmis squamula, M. patens, Baylisascaris devosi, Physaloptera sp., Soboliphyme baturini, and T. spiralis). Trichinella spiralis …

I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …

Leafy Spurge: Threat To Central Plains Grasslands, Robert A. Masters
Leafy Spurge: Threat To Central Plains Grasslands, Robert A. Masters
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Leafy spurge (Euphorbia esula L.) is a noxious weed that threatens grasslands in the central and northern Great Plains and the prairie provinces of Canada. Leafy spurge threatens prairie communities by displacing native species and reducing species diversity. Effective management of this undesirable plant requires that one be able to identify leafy spurge, understand the characteristics that contribute to its aggressive habit, and be aware of practices that are available to control this noxious weed. The aggressive habit of leafy spurge is related to its ability to reproduce both by seed and by numerous adventitious shoot buds located along …
