Zion National Park Environment Assessment/ Assessment Of Effect, Engineering-Environmental Management, Inc.

Elusive Documents

This environmental assessment I assessment of effect examines in detail two alternatives: no action and the National Park Service preferred alternative. The preferred alternative considers rehabilitation of the roadway and associated structures on either side of Route 10 (Zion-Mt. Carmel Highway) tunnel. The road work would primarily occur on the east side of the tunnel in a 0.25-mile segment beginning at the east tunnel entrance. Modifications on the east side of the tunnel would include slurry sealing the road surface and scaling rock slopes on both sides of the road; re-configuring two parking areas; creating a painted center median with …

The Distribution Of Mortality In U.S. Counties, L. Dwight Israelsen, Ryan D. Israelsen, William J. Israelsen

Economic Research Institute Study Papers

Previous studies on life expectancy by U.S. county have found large differences among counties in life expectancy at birth for both males and females. Various determinants of these differences have been identified, including economic, education, demographic, social, geographic, climatic, and environmental factors. This study uses mortality data to identify the distribution of mortality (age at death) and mortality Gini coefficients byU.S. county for males and females for each year between 1985 and 1994. The study also takes a preliminary look at differences in county mortality Gini coefficients among states, regions, and over time. The counties with the smallest degree of …

Record Of Decision: Operation Of Flaming Gorge Dam Final Environmental Impact Statement, U.S. Bureau Of Reclamation

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

The Bureau of Reclamation (Reclamation) has completed a final environmental impact statement (EIS) on the operation of Flaming Gorge Dam. The EIS describes the potential effects of modifying the operation of Flaming Gorge Dam to assist in the recovery of four endangered fish, and their critical habitat, downstream from the dam. The four endangered fish species are Colorado pikeminnow (Ptychocheilus lucius), humpback chub (Gila cypha), razorback sucker (Xyrauchen texanus), and bonytail (Gila elegans). Reclamation would implement the proposed action by modifying the operations of Flaming Gorge Dam, to the extent possible, to achieve the flows and temperatures recommended by participants …

Evaluation Of Immunomodulators, Interferons And Known In Vitro Sars-Cov Inhibitors For Inhibition Of Sars-Cov Replication In Balb/C Mice, Dale L. Barnard, C. W. Day, K. Bailey, M. Heiner, R. Montgomery, L. Lauridsen, P. K-S. Chan, R. W. Sidwell

Animal, Dairy, and Veterinary Science Faculty Publications

Compounds approved for therapeutic use and in vitro inhibitors of severe acute respiratory syndrome coronavirus (SARS-CoV) were evaluated for inhibition in the mouse SARS-CoV replication model. A hybrid interferon, interferon alpha (IFN-alpha) B/D, and a mismatched double-stranded (ds) RNA interferon (IFN) inducer, Ampligen® (poly I:poly C124), were the only compounds that potently inhibited virus titres in the lungs of infected mice as assessed by CPE titration assays. When mice were dosed intraperitoneally (i.p.) with IFN-alpha B/D once daily for 3 days beginning 4 h after virus exposure, SARS-CoV replication in the lungs of infected mice was reduced by 1 log10 …

Setting Expectations For The Ecological Condition Of Running Waters: The Concept Of Reference Condition, J. L. Stoddard, P. Larsen, Charles P. Hawkins, R. K. Johnson, R. H. Norris

Watershed Sciences Faculty Publications

An important component of the biological assessment of stream condition is an evaluation of the direct or indirect effects of human activities or disturbances. The concept of a “reference condition” is increasingly used to describe the standard or benchmark against which current condition is compared. Many individual nations, and the European Union as a whole, have codified the concept of reference condition in legislation aimed at protecting and improving the ecological condition of streams. However, the phrase “reference condition” has many meanings in a variety of contexts. One of the primary purposes of this paper is to bring some consistency …

Quantifying Biological Integrity By Taxonomic Completeness: Evaluation Of A Potential Indicator For Use In Regional-And Global-Scale Assessments, Charles P. Hawkins

Watershed Sciences Faculty Publications

Water resources managers and conservation biologists need reliable, quantitative, and directly comparable methods for assessing the biological integrity of the world's aquatic ecosystems. Large-scale assessments are constrained by the lack of consistency in the indicators used to assess biological integrity and our current inability to translate between indicators. In theory, assessments based on estimates of taxonomic completeness, i.e., the proportion of expected taxa that were observed (observed/expected, O/E) are directly comparable to one another and should therefore allow regionally and globally consistent summaries of the biological integrity of freshwater ecosystems. However, we know little about the true comparability of O/E …

Terpenes And Carbohydrate Source Influence Rumen Fermentation, Digestibility, Intake, And Preference In Sheep, J. J. Villalba, F. D. Provenza, K. C. Olson

Green Canyon Environmental Research Area, Logan Utah

We hypothesized that toxins and nutrients in foods interact to influence foraging behavior by herbivores. Based on this hypothesis we predicted that 1) terpenes in big sagebrush (Artemisia tridentata) influence intake and preference in sheep for diets varying in sources of nonstructural (barley grain) and structural (sugar beet pulp) carbohydrates, and 2) these effects are due to the differential effects of terpenes on fermentation products and apparent digestibility of each class of carbohydrates. Lambs were fed 2 isoenergetic and isonitrogenous diets with varying proportions of the same ingredients (beet pulp- and barley grain-based diet) or offered a choice between the …

Revegetation Of Reconstructed Reaches Of The Provo River, Heber Valley, Utah, John A. Rice

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

Prior to the 1950s, the middle Provo River in Utah offered outstanding fish and wildlife habitat. This was due in part to the Provo River freely meandering through the Heber Valley. These bends in the river provided deep holes for fish and a dense streamside forest for many species of birds. This productive habitat was altered in the 1940s and 1950s when the river was dammed, channelized, and forced between dikes (figure 1). These dikes were constructed by the USDI Bureau of Reclamation (USBR) to contain high flows that came from additional water added to the Provo River from transbasin …

Five Good Reasons For Engineering As The Focus For Technology Education, Robert C. Wicklein

Publications

The article presents information on a paper which discusses why engineering design should be the focus for technology education. Technology education is still viewed as a non-essential instructional program and this is because school administrators and counselors have inadequate understanding of it. Even general populace have inadequate understanding concerning technology education. The pervasiveness of technology literally affects every living creature in our society. Therefore, it is of critical importance that the educational system includes and supports the study of technology in the general curricula. The deficiency within the technology education profession to formulate a clear and defined target for the …

A Voice In The Wilderness, Michael Austin

All USU Press Publications

In her writings, Terry Tempest Williams repeatedly invites us as readers into engagement and conversation with both her and her subject matter, whether it is nature or society, environment or art. From her evocation, in Desert Quartet: An Erotic Landscape, of an eroticism of place that defines erotic as "in relation," to the spiritual connectivity and familial bonds she explores in Refuge: An Unnatural History of Family and Place and the political engagement she urges in The Open Space of Democracy, much of her work is about relationship, connection, and community. Like much good writing, her books invite readers into …

From The Ground Up, Colleen K. Whitley

All USU Press Publications

Mining had an enormous role, only partly measurable, in the history of Utah. Its multidimensional impact continues today. Economically, it made a major long-term contribution to the wealth, employment, and tax base of the state and stimulated a seemingly endless range of secondary businesses and enterprises. It helped shape the state's social history, determining the location, distribution, and composition of many communities and bringing transportation systems and a wide variety of institutions to them. It developed cultural diversity by drawing to Utah miners and families from otherwise underrepresented ethnic and national backgrounds. It ignited strife, particularly between labor and management, …

Livestock Grazing And The Utah Prairie Dog: Implications For Managing The Awapa, R. D. Elmore, Terry A. Messmer

Wildland Resources Faculty Publications

The Utah prairie dog (Cynomys parvidens) is a federally listed species that occurs only in southwestern Utah. The Awapa Plateau in south-central Utah is one of three Utah prairie dog recovery areas. The prairie dog population in this area is below recovery goals established in 1991 by the U.S. Fish and Wildlife Service (USFWS). In 2002, the USFWS approved three Utah prairie dog mitigation banks on the Awapa Plateau. Little information exists regarding how these mitigation banks should be managed to optimize benefits for the species. Past research has suggested that management actions to reduce shrub canopy cover …

Toward A Unified Science Of The Earth's Surface: Opportunities For Synthesis Among Hydrology, Geomorphology, Geochemistry, And Ecology, C. E. Foufoula-Georgiou, W. E. Dietrich, M. Hondzo, D. Mohrig, G. Parker, M. E. Power, I. Rodriguez-Iturbe, V. Voller, P. Wilcock

Watershed Sciences Faculty Publications

The Earth's surface is shaped by the interaction of tectonics, water, sediment, solutes, and biota over a wide range of spatial and temporal scales and across diverse environments. Development of a predictive science of Earth surface dynamics integrates many disciplines and approaches, including hydrology, geomorphology, ocean and atmospheric science, sedimentary and structural geology, geochemistry, and ecology. This paper discusses challenges, opportunities, and a few example problems that can serve as pathways toward this integration.

The Ciego In The Novels Of Galdós: Costumbrismo, Realism, Symbolism, Vernon Chamberlin

Decimonónica

Like many of his contemporaries, both in Spain and other European countries, Galdós utilized many blind characters in his novels¹. Although he was unaware of the fact as he created these characters, he himself would spend his final years sightless. Individual Galdosian blind characters are sometimes mentioned by critics as part of the overall discussion of specific works, but to date there has been no study showing how pervasive the ciego is throughout the vast panorama of Galdós’s works. Therefore, the aim of the present study is to demonstrate that the ciego, and the multiplicity of his …

“Beethoven” And “Sigue Beethoven”: The Sonata-Form Structure Of Galdós’S La Desheredada, Vernon A. Chamberlin

Decimonónica

It has been demonstrated that while creating the novel Tristana, as well as the first volume of Fortunata y Jacinta, Galdós did clearly follow the musical pattern known as sonata form.¹ This musical design is most frequently used as the basic structure for the first or last movement of a sonata (and sometimes also for the first movement of a symphony, as in the case of Beethoven’s Third [Eroica] Symphony). In creative fiction it has served as a model for such well-known authors as James Joyce, Virginia Woolf, E. M. Forster, Thomas Mann, Hermann Hesse, …

Salinity Controls Phytoplankton Response To Nutrient Enrichment In The Great Salt Lake, Utah, Usa, Amy M. Marcarelli, Wayne A. Wurtsbaugh, O. Griset

Watershed Sciences Faculty Publications

To examine how salinity and nutrient supply interact to control phytoplankton community composition, nutrient limitation, and dinitrogen (N2) fixation rates in the Great Salt Lake (Utah, USA), we conducted a series of bioassay experiments with plankton from both Gilbert Bay, where salinities are near 160 g·L–1, and Farmington Bay, where salinities range from 10 to 90 g·L–1. Six-day nutrient addition bioassay experiments showed that the extant phyto plankton communities in both bays were limited by nitrogen (N). However, in 28- to 30-day factorial bioassay experiments in which both salinities and nutrient supply were manipulated, phosphorus stimulated chlorophyll a as much …

Good Practices For Sharing Ecological Models, Karin M. Kettenring, Barbara T. Martinez, Anthony M. Starfield, Wayne M. Getz

Watershed Sciences Faculty Publications

As the fields of ecology and conservation biology increasingly rely on models to address pertinent questions, there has been greater sharing of models among scientists. However, many models lack comprehensive documentation, especially in a format that is easy to use and to understand. Also, modelers lack a framework they can use when evaluating a model for its potential use. Here we outline how ecologists and conservation biologists can begin to establish a culture of good practice for model sharing. We offer suggestions on how model developers, model users, user communities, and journal editors can contribute to the appropriate sharing of …

A Design-Based Research Strategy To Promote Scalability For Educational Innovations, Jody Clarke-Midura, C. Dede, D. J. Ketelhut, B. Nelson, C. Bowman

Instructional Technology and Learning Sciences Faculty Publications

This article offers insights into how the design of innovations can enhance their “scalability”: the ability to adapt an innovation to effective usage in a wide variety of contexts, including settings where major conditions for success are absent or attenuated. We are implementing the River City MUVE curriculum, a technology-based innovation designed to enhance engagement and learning in middle school science, in a range of educational contexts. Based on our studies of these scaling up activities, we offer examples of design strategies for scalability and describe our plan to develop a “scalability index.”

Comparative Toxicosis Of Sodium Selenite And Selenomethionine In Lambs, A. K. Tiwary, B. L. Stegelmeier, K. E. Panter, L. F. James, Jeffery O. Hall

Animal, Dairy, and Veterinary Science Faculty Publications

Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite or selenomethionine and were monitored for 7 days, after which they were euthanized and necropsied. Twelve randomly assigned treatment groups consisted of animals given 0, 1, 2, 3, or 4 mg of Se/kg of body weight as sodium selenite, or 0, 1, …

Factors Affecting Greater Sage-Grouse Habitat Use In Utah's West Desert, J. D. Robinson, Terry A. Messmer

Wildland Resources Faculty Publications

Two species of sage-grouse occur within the western United States, the greater sage-grouse (Centrocercus urophasianus) and the Gunnison sage-grouse (C. minimus). The Gunnison sage-grouse is a candidate species for listing under the Endangered Species Act. This species occurs in a small range in southwest Colorado and southeast Utah. The greater sage-grouse occurs in a larger range throughout the western United States.

Potential Predators Of An Invasive Frog (Eleutherodactylus Coqui) In Hawaiian Forests, Karen H. Beard, William C. Pitt

Wildland Resources Faculty Publications

In Hawaii, where there are no native reptiles or amphibians, 27 species of reptiles and amphibians have established; however, few have been studied to determine their ecological impacts. For example, little is known about the impacts of the Puerto Rican frog, Eleutherodactylus coqui Thomas, that recently invaded (late 1980s), and has established on all four main Hawaiian Islands. However, there are likely to be consequences because E. coqui can attain high densities (20570 frogs ha⁻¹ on average in Puerto Rico) and consume large quantities of invertebrates (114000 prey items ha⁻¹ per night on average in Puerto Rico).
