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 …

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

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 …

Critical Inquiry Into Urban African American Students' Perceptions Of Engineering, Cameron D. Denson, Zanj K. Avery, John W. Schell

Reports of Center Studies

The purpose of this study was to critically examine the perceptions that African- American high school students have towards engineering. A qualitative research design using criterion sampling and snowballing was used to select seven African-American students from urban high schools to participate in the research. Semi-structured interviews were used to collect data from participants attending urban high schools on the east and west coast. Using Critical Race Theory (CRT) as the theoretical framework, the study was able to produce “emergent themes” from collected data. Findings from this study will help researchers understand how African-American students may perceive the field of …

Young Women’S Perceptions Of Technology And Engineering: Factors Influencing Their Participation In Math, Science And Technology?, Leah C. Roue

Reports of Center Studies

The current number of women in technology and engineering only represents a fraction of today’s workforce. Technological innovation depends on our nation’s best and brightest, representing all segments of our diverse society. Sanders (2005), in talking about women in technology and engineering, stated that women’s lack of participation can only be measured in jobs not filled, problems not solved, and technology not created. Research in the area of how young women view technology will provide insights into how to better encourage and prepare them for careers in technology and engineering.

The purpose of this exploratory study was to examine four …

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 …

Estimating The Effectiveness Of A Vehicle Miles Traveled Tax In Reducing Particulate Matter (Pm2.5) Emissions, Jordan Carroll-Larson, Arthur J. Caplan

Economic Research Institute Study Papers

This study estimates the effectiveness of a vehicle miles traveled (VMT) tax in controlling mobile-source emissions of particulate matter (PM2.s) in a non-attainment area located in northern Utah. Using a recently updated household-level dataset, we find no evidence of an endogenous relationship between choice of vehicle type and VMT. We also estimate VMT elasticities with respect to cost per mile that are in some cases larger in magnitude than those reported in previous studies. Based on vehicle emissions tests performed by the Houston Advanced Research Center, we estimate the reduction in PM2.s emissions that would occur with two different sets …

Before The Manifesto: The Life Writings Of Mary Lois Walker Morris, Melissa Lambert Milewski

Mary Lois Walker Morris was a Mormon woman who challenged both American ideas about marriage and the U.S. legal system. Before the Manifesto provides a glimpse into her world as the polygamous wife of a prominent Salt Lake City businessman, during a time of great transition in Utah. This account of her life as a convert, milliner, active community member, mother, and wife begins in England, where her family joined the Mormon church, details her journey across the plains, and describes life in Utah in the 1880s. Her experiences were unusual as, following her first husband's deathbed request, she married …

The Arc And The Sediment, Christine Allen-Yazzie

All USU Press Publications

Gretta Bitsilly, gin-steeped mother of two and self-proclaimed expert at standing outside the margins of ethnicity and peering in, has been all but eclipsed by the world that eludes her--as a wife, a writer, a skeptic in "the other land of Zion," Utah. Gretta has set off to Fort Defiance, Arizona, where she hopes to convince her Navajo husband, who has escaped not from his family but from alcoholism, to come home.

Over a sputtering two-steps-forward, one-step-back desert journey, Gretta is diverted by chance, seizures, an inconstant memory, and the disjointed character of her irresolute quest.

She is fueled by …

She did not actively seek or expect to reach what was arguably the most powerful political position any American woman had ever held, chair of the Democratic National Committee. A Utah national committeewoman who time and again had demonstrated her ability to organize effectively and campaign hard, as well as her devotion to reform, Westwood answered George McGovern's call to lead his presidential campaign. In the dramatic year of 1972, she became the first woman to chair a national political party, McGovern lost in a landslide, Nixon was reelected, and a …

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 …

Western Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Richard F. Miller, Jonathan D. Bates, T. J. Svejcar, Frederick B. Pierson, L. E. Eddleman

Reports

Strong evidence indicates that western juniper has significantly expanded its range since the late 1800s by encroaching into landscapes once dominated by shrubs and herbaceous vegetation (fig. 1). Woodland expansion affects soil resources, plant community structure and composition, water, nutrient and fire cycles, forage production, wildlife habitat, and biodiversity. Goals of juniper management include an attempt to restore ecosystem function and a more balanced plant community that includes shrubs, grasses, and forbs, and to increase ecosystem resilience to disturbances. Developing a management strategy can be a difficult task due to uncertainty about how vegetation, soils, hydrologic function, and wildlife will …

Development Of A Rivpacs-Type Predictive Model For Bioassessment Of Wadeable Streams In Wyoming, Hargett E. G., J. R. Zumberge, Charles P. Hawkins, J. R. Olson

Watershed Sciences Faculty Publications

RIVPACS models produce a community-level measure of biological condition known as O/E, which is derived from a comparison of the observed (O) biota with those expected (E) to occur in the absence of anthropogenic stress. We used benthic macroinvertebrate and environmental data collected at 925 stream monitoring stations, from 1993 to 2001, to develop, validate, and apply a RIVPACS model to assess the biological condition of wadeable streams in Wyoming. From this dataset, 296 samples were identified as reference, 157 of which were used to calibrate the model, 46 to validate it, and 93 to examine temporal variability in reference …

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 …

The So-Called Problem Of Closure In Fortunata Y Jacinta And Tristana Revisited By Means Of Musical Structure, Vernon Chamberlin

Decimonónica

Critics continue to be puzzled by the closure of both Fortunata y Jacinta and Tristana. For example, in 1986 Hazel Gold published “Problems of Closure in Fortunata y Jacinta: Of Narrators, Readers, and Their Just Deserts/Desserts.” Then she returned to the subject seven years later, still of the opinion that “the question of closure must have seemed an especially thorny one for the author of Fortunata y Jacinta” (Reframing 51). In 1991, José Manuel del Pino brought forth “El Fracaso de los sistemas de cierre de Fortunata y Jacinta.” Similarly with Tristana, from “Clarín” …

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 …

The Bear River is the major river in the watershed but does not directly feed Bear Lake....

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

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 …
