Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers Jan 2007

Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers

All U.S. Government Documents (Utah Regional Depository)

In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen’s epiphytic lichen …

Aphis’ Plant Inspection Stations: Protecting American Agriculture From Foreign Pests And Diseases, United States Department Fo Agriculture, Animal And Plant Health Inspection Service

All U.S. Government Documents (Utah Regional Depository)

In today’s global marketplace, the volume of international trade brings increased potential for the introduction of foreign pests, diseases, and noxious weeds that could threaten the safety of American agriculture. The results of such introductions can have a devastating effect on the U.S. food supply, damage our natural resources, and cost hundreds of millions of dollars in eradication and control measures that ultimately result in higher priced agricultural products for the consumer.

Self-Medication And Homeostatic Behaviour In Herbivores: Learning About The Benefits Of Nature’S Pharmacy, Juan J. Villalba, Frederick D. Provenza Jan 2007

Self-Medication And Homeostatic Behaviour In Herbivores: Learning About The Benefits Of Nature’S Pharmacy, Juan J. Villalba, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

Traditional production systems have viewed animals as homogeneous ‘machines’ whose nutritional and medicinal needs must be provided in a prescribed manner. This view arose from the lack of belief in the wisdom of the body to meet its physiological needs. Is it possible for herbivores to select diets that meet their needs for nutrients and to write their own prescriptions? Our research suggests it is. Herbivores adapt to the variability of the external environment and to their changing internal needs not only by generating homeostatic physiological responses, but also by operating in the external environment. Under this view, food selection …

Home Range Characteristics Of Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper Jan 2007

Home Range Characteristics Of Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper

Canyonlands Research Bibliography

We studied home-range characteristics of adult Mexican Spotted Owls (Slyix occidentalis lucida) in southern Utah. Twenty-eight adult owls were radio-tracked using a ground-based telemetry system during 1991-95. Five males arid eight females molted tail feathers and dropped transmitters within 4 wk. We estimated cumulative home ranges for 15 Spotted Owls (12 males, 3 females). The mean estimate of cumulative home-range size was not statistically different between the minimum convex polygon and adaptive kernel (AK) 95% isopleth. Both estimators yielded relatively high SD, and male and fernale range sizes varied widely. For 12 owls tracked during both the breeding and nonbreeding …

The Dynamics Of Social Capital And Conflict Management In Multiple Resource Regimes: A Case Of The Southwestern Highlands Of Uganda, Pascal C. Sanginga, Rick N. Kamugisha, Andrienne M. Martin Jan 2007

The Dynamics Of Social Capital And Conflict Management In Multiple Resource Regimes: A Case Of The Southwestern Highlands Of Uganda, Pascal C. Sanginga, Rick N. Kamugisha, Andrienne M. Martin

All UNF Research

Increasingly, social capital, defined as shared norms, trust, and the horizontal and vertical social networks that facilitate coordination and cooperation for mutually beneficial collective action, is seen as an important asset upon which people rely to manage natural resources and resolve conflicts. This paper uses empirical data from households and community surveys and case studies, to examine the role, strengths, and limits of social capital in managing conflicts over the use and management of natural resources. We inventoried over 700 cases ranging from conflicts between multiple resource users to supra-community conflicts between local communities concerns for better livelihoods and national/international …

Haunting Experiences: Ghosts In Contemporary Folklore, Diane E. Goldstein, Sylvia Ann Grider, Jeannie B. Thomas Jan 2007

Haunting Experiences: Ghosts In Contemporary Folklore, Diane E. Goldstein, Sylvia Ann Grider, Jeannie B. Thomas

All USU Press Publications

Ghosts and the supernatural appear throughout modern culture, in any number of entertainment, commercial, and other contexts. Popular media's commodified representations of ghosts can be quite different from what people believe about them, based on tradition or direct experience. Belief and tradition and the popular or commercial nevertheless continually feed off each other. They frequently share space in how people think about the supernatural. In Haunting Experiences, three well-known folklorists broaden the discussion of ghost lore by examining it from multiple angles in various modern contexts. Diane E. Goldstein, Sylvia Ann Grider, and Jeannie Banks Thomas take ghosts seriously. They …

Improving The Effectiveness Of Interventions To Balance Conservation And Development: A Conceptual Framework, S. Garnett, J. Sayer, Johan T. Du Toit Jan 2007

Improving The Effectiveness Of Interventions To Balance Conservation And Development: A Conceptual Framework, S. Garnett, J. Sayer, Johan T. Du Toit

Wildland Resources Faculty Publications

There are numerous case studies around the world describing integrated conservation and development projects (ICDPs). Recently some localized syntheses have been published that use sophisticated statistics to identify patterns and causal linkages, but no attempt has yet been made to draw together lessons from across the globe. This paper is an attempt to provide a framework for such an analysis. A set of lessons is proposed for improving the prospects of ICDPs by giving consideration to each of the five capitals: natural, social, human, built, and financial. The language of ICDPs has been adopted by development agencies of all persuasions. …

A Meta-Baci Approach Forevaluating Management Intervention On Chronic Wasting Disease In Mule Deer, Mary M. Conner, Michael W. Miller, Michael Ryan Ebinger, Kenneth P. Burnham

Wildland Resources Faculty Publications

Advances in acquiring and analyzing the spatial attributes of data have greatlyenhanced the potential utility of wildlife disease surveillance data for addressing problems ofecological or economic importance. We present an approach for using wildlife diseasesurveillance data to identify areas for (or of ) intervention, to spatially delineate pairedtreatment and control areas, and then to analyze these nonrandomly selected sites in a meta-analysis framework via before–after–control–impact (BACI) estimates of effect size. We applythese methods to evaluate the effectiveness of attempts to reduce chronic wasting disease(CWD) prevalence through intensive localized culling of mule deer (Odocoileus hemionus)innorth-central Colorado, USA. Areas where surveillance data …

Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze Jan 2007

Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze

Animal, Dairy, and Veterinary Science Faculty Publications

Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with different ratios between the 2 activities, were assessed at a DR of 0.7, 1.4, and 2.1 mg/g of DM forage. Milled alfalfa hay or corn silage was incubated in an in vitro batch culture with buffer, ruminal fluid, and EFE. Gas production (GP) was measured …

Enhancing In Vitro Degradation Of Alfalfa Hay And Corn Silage Using Feed Enzymes, Jong-Su Eun, K. A. Beauchemin Jan 2007

Enhancing In Vitro Degradation Of Alfalfa Hay And Corn Silage Using Feed Enzymes, Jong-Su Eun, K. A. Beauchemin

Animal, Dairy, and Veterinary Science Faculty Publications

A series of in vitro fermentation experiments was performed to assess the effects of 4 feed enzyme products (FE) that varied in enzymatic activities on the degradation of alfalfa hay and corn silage. The FE contained a range of endoglucanase, exoglucanase, xylanase, and protease activities, and a range of dose rates (DR) was used. The objective of the study was to identify effective formulations and optimum DR, and to establish if combining FE would further improve fiber degradation. For alfalfa hay, quadratic increases in gas production and degradation of dry matter (DM) and fiber were observed for all FE, with …

Bear Lake Basin : History, Geology, Biology, People, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Bear Lake Basin : History, Geology, Biology, People, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

Bear Lake is a large, deep lake located on the border of Utah and Idaho in Rich County Utah and Bear Lake County Idaho. It was formed through seismic activity along a fault on the eastern side of the lake. Tectonic shifts of the plates along this fault resulted in a lake basin that is over 200 ft deep along the eastern shore with a gradual slope to the western shore. The lake water has high concentrations of calcium carbonate because of high levels of evaporation typical of this semi-arid climate. These high concentrations of calcium carbonate give the lake …

Birds And Mammals Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Birds And Mammals Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

Many bird species use Bear Lake seasonally or during migrations. Herons, egrets, sandpipers, rails, pelicans, geese, coots, grebes, Tundra swans and osprey are common visitors throughout the year. During the spring months of April through June the area becomes the primary breeding grounds for the burrowing owl, gray flycatcher, long-billed curlew, peregrine falcon, and the black-throated gray warbler. Early in the summer months, several species of mergansers and diving ducks converge on the rocky shorelines to fish as the newly hatched Bear Lake sculpin occupy shallow waters during this period. During winter the area becomes critical habitat for the American …

Biological Resources Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Biological Resources Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

The Bear Lake basin has a range of land types that provide habitat for aquatic, riparian, and terrestrial wildlife and plant species. Near the lake a limited ring of semi aquatic plants grow in association with spring and creek waters. Agriculture lands are used as pasture and to grow feed crops such as hay and alfalfa. Larger stream inflows host riparian and aquatic meadow plants. The low hills of the valley support sagebrush, grasslands, pinion, juniper, maple, and brushy communities. In the higher mountains brushes give way to large tree complexes of aspen, spruce, pine, and their associated undergrowths. The …

No Annulment: Three Women Characters Of The Mid-1880s Confront The Problem Of An Impossible Marriage (Manuel Cubas, Sawa, Galdós), Vernon Chamberlin Jan 2007

No Annulment: Three Women Characters Of The Mid-1880s Confront The Problem Of An Impossible Marriage (Manuel Cubas, Sawa, Galdós), Vernon Chamberlin

Decimonónica

Distaff discontent with matrimony has been a subject of literary treatment throughout the ages. In Classical, Renaissance, and Golden Age times, the emphasis was often on the cleverness of the wife in securing and protecting a lover—one who could supplement or even fulfill completely the husband’s amatory role. Certainly, there was a diversity of reasons for the wife’s discontent and her need for remedial action. For example, in Apuleius’s The Golden Ass, the problem is that the wife has a more zesty nature than does her spouse (IX, 407). In Boccaccio’s Decameron, the husband’s neglect of his wife …

Reescritura, Melodrama Y Moralización En Alceste, De B. P. Galdós (Eco En Las Últimas Heroínas Dramáticas Del Escritor), Eloy E. Merino

Decimonónica

Alceste se estrena en el teatro de la Princesa en Madrid el 21 de abril de 1914. Como sugiere Carmen Menéndez Onrubia, Galdós parece que comienza a conceptualizar el argumento ya desde 1895, para mostrar su desprecio por el gobierno trino que se pretendía formar con la reina regente María Cristina y los padres del difunto Alfonso XII (137, 175). Esto indica casi veinte años de incubación, detalle no insignificante ya que de haberla completado entonces, la tragedia habría presentado tal vez un tono menos contemporizador que el que muestra en 1914. En enero de 1894 ocurre, como ilustración, el …

Winning By A Neck: Tall Giraffes Avoid Competing With Smaller Browsers, E. Z. Cameron, Johan T. Du Toit Jan 2007

Winning By A Neck: Tall Giraffes Avoid Competing With Smaller Browsers, E. Z. Cameron, Johan T. Du Toit

Wildland Resources Faculty Publications

With their vertically elongated body form, giraffes generally feed above the level of other browsers within the savanna browsing guild, despite having access to foliage at lower levels. They ingest more leaf mass per bite when foraging high in the tree, perhaps because smaller, more selective browsers deplete shoots at lower levels or because trees differentially allocate resources to promote shoot growth in the upper canopy. We erected exclosures around individual Acacia nigrescens trees in the greater Kruger ecosystem, South Africa. After a complete growing season, we found no differences in leaf biomass per shoot across height zones in excluded …

Comparing Citizens' And Managers' Concerns About Sagebrush Management And Restoration In The Great Basin, Mark W. Brunson, Jennifer Peterson Jan 2007

Comparing Citizens' And Managers' Concerns About Sagebrush Management And Restoration In The Great Basin, Mark W. Brunson, Jennifer Peterson

Reports

The Great Basin sagebrush steppe ecosystem is among the most imperiled in the U.S. Cheatgrass invasion, conifer encroachment, and catastrophic wildfires are considered to be primary catalysts of decline. Efforts are underway to restore and increase the resiliency of this damaged ecosystem through broad-scale applications of fuel reduction and restoration treatments involving mechanical removal, prescribed fire, and herbicide application. While research points to the potential benefits of these treatments, controversy and challenge often surface when treatments are proposed on public lands. Therefore it is critical for land managers to understand the views held by key stakeholder groups concerning management and …

Pedagogical Agents As Social Models To Influence Learner Attitudes, Yanghee Kim, A. Baylor Jan 2007

Pedagogical Agents As Social Models To Influence Learner Attitudes, Yanghee Kim, A. Baylor

Instructional Technology and Learning Sciences Faculty Publications

Based on social-cognitive theory, we describe the role of pedagogical agents as “social models.” In several experimental studies we have found that pedagogical agents as social models can effectively persuade and motivate learners. We briefly describe two on-going projects where agents as social models are employed to enhance young women’s motivation and attitudes toward math and engineering.
