No simple answer to "What killed the Aspen?"

Mary Lou Fairweather

The recent impacts to aspen in central Arizona are so apparent that I even get questioned at social gatherings: “Tell me again, what is killing the aspen?” The answer is complicated, and harkens back to a muddled media interview. I met the reporter at the Arboretum at Flagstaff and rambled on about drought, spring frost, fire suppression, forest succession, secondary insects and diseases, and ungulate browsing. “But what killed the aspen?” the reporter asked. Nearby an Arboretum docent led a group of visitors to a small aspen grove and …

A Classroom Experiment: Implementing A Math-Talk Environment In A University Setting, Janice Bodily

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A need for reform in teaching mathematics has long been recognized. The traditional classroom with the sage on the stage lacks a higher level of engagement for the students and therefore, produces a lower level of student satisfaction. The math-talk classroom is one attempt to engage students and to raise the level of interaction and discussion, thus enabling students to increase their level of comprehension. In an effort to create a math-talk experience in my Calculus II course, I applied the methodology of Thinking Through a Lesson Protocol (TTLP) to test its effectiveness in assisting the instructor in creating an …

A Mechanistic Study Of Catalytic Promiscuity In Protein Phosphatase 1, Yuan Chu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"Catalytic promiscuous" enzymes, which possess additional activities besides their "native" activity, albeit with a lower efficiency than the main reaction, have become a new frontier for biochemistry and have received considerable attention. Catalytic promiscuity has been suggested to contribute to enzyme evolution through the mechanism of gene duplication followed by specialization of one of the two copies for the new function. Mimicking this evolutionary shortcut could also provide a more efficient route to changing the function of proteins by directed evolution.

The promiscuous phosphatase PP1 is a member of the phosphoprotein phosphatase (PPP) gene family, which is critical for the …

Marital Quality, Acculturation, And Communication In Mexican American Couples, Audrey Lyn Schwartz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marital quality is a broad measurement of perceptions of satisfaction, happiness, and stability by partners in an established relationship. Marital quality has been relatively understudied among Mexican Americans, a population that warrants the inclusion of cultural constructs in any model concerning relationship outcomes. Therefore, acculturation differences between Mexican American couples were conceptualized as a distal context for understanding marital quality. Traditional gender role values and communication style (warmth and hostility) were included as proximal contexts. Data from Conger’s California Families Project were utilized; results indicated that while most measures of acculturation did not impact marital quality, language use interacted with …

The Use Of Life History Collage To Explore Learning Related To The Enactment Of Social Consciousness In Female Nonprofit Leaders, Susan R. Seymour

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper advances a novel qualitative research approach using life history collage. Rather that utilizing an interview protocol to enter into a participant’s story, life history collage invites participants to create a longitudinal collage of significant life events around a theme such as learning, relationships, or identity. The longitudinal nature of the collage situates and prioritizes significant life events with images, words, and elements chosen to represent events and circumstances. Each image within the collage contains rich and nuanced storylines that invite exploration by both researcher and participant. Meanings and subtexts are revealed as participants describe their collage and the …

Interactions Between Rocky Mountain Bighorn Sheep Ovis Canadensis Canadensis And Domestic Sheep Ovis Aries And The Biological, Social, Economic, And Legal Implications Of These Interactions On Usda Forest Service Lands In The Evanston/Mt. View Ranger District, Ashly Nicole Herrera

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Strong evidence exists indicating domestic sheep (Ovis aries) can infect Rocky Mountain bighorn sheep (Ovis canadensis canadensis), a United States Forest Service (USFS) Region 4 sensitive species, with pneumonia (Callan 1991; Foreyt 1989, 1992, 1994; Foreyt and Lagerquist 1996; George et al 2008; Wehausen et al. 2011). Since the transmission of the pneumonic bacteria between the domestic and wild sheep is a result of bighorn sheep coming into contact with the bacteria carried in the mucous membranes of the domestic sheep, bighorn sheep at risk of initially contracting the bacteria are those individuals that enter areas currently being grazed or …

An Exploration Of The Relationships Among Connectedness To Nature, Quality Of Life, And Mental Health, Peter G. Tauber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent decades, a new branch of psychology has emerged—ecopsychology. This field looks at the complex relationship between human beings and the natural world. Previous research has shown the importance of direct experiences in nature for the promotion of human health and well-being. However, it is still not understood why these experiences in nature carry so much importance.

It is possible that the concept of connectedness to nature (CTN) plays a role in this relationship between nature and wellness. CTN is defined as feelings of close affiliation with the natural world in a physical, cognitive, and emotional manner. Previous research …

Effects Of Planting Date, Harvest Date, And Environmental Conditions On Germination Of Forage Kochia Accessions, Cody F. Creech

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forage kochia is used to re-seed areas in harsh environments that have been infested by annual weeds or disturbed by repetitive fires. It is an introduced perennial semi-shrub that is valuable to livestock and wildlife as a forage. The seed of forage kochia is very unpredictable and successful establishment in areas of low precipitation where it is utilized has often been erratic. Forage kochia seeding failures are costly and leave the land vulnerable to further degradation and erosion. This study was conducted to investigate how germination of forage kochia is affected by different harvest and planting dates, age of seed, …

Waste Heat Utilization In An Anaerobic Digestion System, Brett Boissevain

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Anaerobic digestion has great potential as an energy source. Not only does it provide an effective method for waste mitigation, but it has the potential to generate significant quantities of fuel and electricity. In order to ensure efficient digestion and biomass utilization, however, the system must be continuously maintained at elevated temperatures. It is technically feasible to supplement such a system with outside energy, but it is more cost effective to heat the system using only the produced biogas. While there is considerable literature covering the theory of anaerobic digestion, there are very few practical studies to show how heat …

The Effects Of Habitat Manipulations On Utah Prairie Dogs (Cynomys Parvidens) And Their Habitat On The Awapa Plateau Recovery Area In South-Central Utah, Gretchen Elizabeth Caudill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah prairie dogs have been listed, in some capacity, under the Endangered Species Act since 1972. The lack of suitable habitat, particularly cool season grass cover,
has been identified as the primary factor impeding species recovery. Due to reproduction costs, Utah prairie dogs require a large quantity of cool season grasses. Lack of recovery has also been attributed to poor juvenile survival. Increased resources have been shown to increase weights, which would increase survival through the winter.

Beneficial habitat management techniques for Utah prairie dogs have yet to be determined for the Awapa Plateau recovery area. Utah prairie dogs require …

Farmer, Miner, Ranger, Writer: Interpreting Class And Work In The Writing Of Wendell Berry And Edward Abbey, Tyler Austin Nickl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study compares some of the essays and novels of two well known, environmental writers: Wendell Berry and Edward Abbey. Usually, these writers are discussed for their environmental politics and representations of nature, but this study examines the ways in which each of these writers discusses class and manual labor. This aspect of Abbey’s and Berry’s works has not yet received the attention it deserves. With this focus in mind, I make the following conclusions: 1) An author’s view of society (as expressed by their opinions of class and socioeconomic status) necessarily affects their view of nature. 2) Berry’s occupational …

Root Uptake Of Organic Contaminants Into Plants: Species Differences, Naho Orita

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Xenobiotic organic contaminants are widely found in the environment, including soils, sediments, surface waters, wastewater streams, and even in drinking water. Food chain contamination resulting from the uptake of these contaminants by plants is a concern. Although the uptake of a variety of xenobiotic organic contaminants by plants has been reported but the differences between plant species are not fully understood. The emphasis of this thesis research is to further investigate the unique root to shoot transfer ability of “gold rush” zucchini that has been reported repeatedly in recent years.

A pressure chamber technique was used to measure transpiration stream …

"Worlds Without End": The Cosmological Theodicy Of Brigham Young, James Chase Kirkham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis proposes an analysis of the teachings of Brigham Young, second President of the Church of Jesus Christ of Latter-day Saints. The study focuses on Young’s more striking doctrine—namely, the eternal nature of matter, the capability of humans to live after death where they would eternally gain knowledge, a universe governed by a race of exalted human beings called gods, and the potential for humans, upon reaching the status of gods and goddesses, to create planets and populate them with their children.

This study uses a three-fold method to understand why some of Young’s teachings were so remarkable. First, …

Continental-Scale Characterization Of Molecular Variation In Quaking Aspen, Colin M. Callahan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quaking aspen has the largest natural distribution of any tree native to North America, ranging from Alaska through the breadth of Canada and south to mid-Mexico. Recent studies suggest a general decline of aspen throughout much of the range since at least the mid-20th century, though these findings remain inconclusive. Regardless, factors such as climate change, periods of drought, soil nutrient deficiencies, pathogens, insects, and encroachment by other tree species all pose risks to the health and maintenance of aspen across the continent. This situation is exemplified in the western United States where climate change is forecasted to have an …

Experimental Studies Of Vertical Mixing In An Open Channel Raceway For Algae Biofuel Production, Ram Sudheer Voleti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The USU BioEnergy Center has been successful in developing algae feedstocks for renewable biofuels and bioproducts. The concept is to utilize and maximize algae feedstocks for liquid transportation fuels, biomass for burning and digestion, and high value co-products. It is theorized that increasing the mixing in open and closed algal production systems improves the productivity of the algae culture. A raceway cultivation system was chosen to examine the phenomena of mixing. Vertical mixing will provide more uniform exposure to sunlight for all of the algae in the raceway. The main focus of this research was to increase vertical mixing. Delta …

The Antimycobacterial Activity Of Hypericum Perforatum Herb And The Effects Of Surfactants, Shujie Shen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tuberculosis is a stubborn and lethal infectious disease. The world-wide tuberculosis surveillance reports that the new TB cases ranges from seven to eight million per year and deaths ranges from 1.3 to 1.6 million every year. The treatment of tuberculosis mainly depends on antituberculosis drugs, such as isoniazid, rifampin, pyrazinamide and ethambutol. However, drug-resistance acquisition is an inevitable process during tuberculosis treatment. Today, multi-drug resistant and the extensively drug-resistant TB cases have been widely reported around the world. Thus, the discovery of novel antituberculosis drugs is essential to effective TB treatment. Hypericum perforatum, also called St. John’s Wort, is …

Value Of Information In Design Of Groundwater Quality Monitoring Network Under Uncertainty, Abdelhaleem I. Khader

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to variations in rainfall and limited surface water resources, groundwater is considered the main source for freshwater in many places throughout the word. But this precious resource is being jeopardized by pollution from human activities such as: industry, agriculture, and untreated wastewater, which highlight the need for efficient groundwater resources management. To be efficient, groundwater resources management requires efficient access to reliable information that can be acquired through monitoring. On the other hand, the complicated nature of groundwater aquifers and the uncertainties in the data and the models used to understand the aquifer and its behavior require more powerful …

Late Adolescents’ Perceptions Of A Digital Generation Gap And Perceived Parent-Child Relations, J. Mitch Vaterlaus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to determine if late adolescents (18-25 year olds) perceived differences between their own knowledge about interactive technology and what they thought their parents knew about the same technology. Secondly, the study sought to understand how differences in these perceived technology were related to adolescent perceptions about their interactions with their parents. The parent-child relationship characteristics of interest in this study were parent-child quality time, parent-child conflict, and parents’ knowledge of their childrens’ behaviors.

Late adolescents did perceive generational differences in technology knowledge in the areas of video chat, cell phones, general social networking, …

Genetic Characterization Of Fine-Leaved Festuca Valesiaca Germplasm And Evaluation Of Their Relationship To The Festuca Ovina Complex, Yingmei Ma

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fine-leaved Festuca valesiaca has stress tolerance. However, its agronomic performance in the western United States and its genetic relationship to species of the Festuca ovina complex has not been investigated. Also, natural hybridization makes them difficult to identify. Given the species' potentials, our project was designed to identify Festuca valesiaca accessions that possess high biomass and seed yield and to examine their relatedness with the Festuca ovina complex.

The Festuca valesiaca accessions examined produced many small seeds. Seed production was correlated with the total biomass, plant height, and plant vigor. The Festuca valesiaca accessions examined were shorter than the control …

The Remarkable Life Of Sanak, Roly Russell, Nancy J. Huntly, Spencer Wood, Bruce Finney, Dieta Hanson

Biology Faculty Publications

Life on Sanak is remarkable—from the brilliant orange of lichens clinging to life high on wave-beaten and barren rocks to the raspy bark of an introduced arctic fox or a vole's abstract bouquet of drying tundra flowers. In this chapter we will explore a limited selection of the diverse cast of characters that inhabit the Sanak Islands, ranging from the tiny and cryptic to the large and charismatic.

The Ecological Interactions Of Sanak, Nancy Huntly, Spencer Wood, Roly Russell

Biology Faculty Publications

Ecology is not only about the interesting biology of organisms, as described for Sanak Island in the last chapter, but also about interactions: interactions between animals (including people), plants, microbes, the habitats that they live in, and the environments that surround them. The ecology of Sanak Island today reflects not only today's conditions, but also shows the imprint of the distant history of interactions of the island, especially, as we will see below, the imprint of the Aleut people that have made this island their home.

How Sanak Aleut Fit Into The Intertidal Food Web, Jennifer A. Dunne, Spencer Wood, Roly Russell, Nancy Huntly, Matthew Betts, Herbert Maschner

Almost everyone learns about the concept of ecological "food chains" in grade school. An example of a marine food chain is shown on the left-hand side of the chart to the left: phytoplankton are eaten by mussels, which are eaten by octopus, which are eaten by sea otters, which are eaten by humans. These feeding interactions can be abstractly represented as five "nodes" connected in a single chain by four links, as shown on the right-hand side of the diagram to the left. The food chain shown is one of the thousands of interlinked food chains that make up the …
