Getting To Know You: Relationship Formation Across Development In Octodon Degus, Amber Lynn Thatcher

Graduate Student Theses, Dissertations, & Professional Papers

Social relationships are a necessary part of group formation and cohesion across many animal species and can increase the health and fitness of the individuals involved. These benefits are seen across the lifespan, although the exact advantages and functions differ across developmental stages. Our current understanding of how relationships are formed and maintained is incomplete. Previous findings suggest that a measure of stability may be a useful method for understanding how relationships are formed and how this process may differ across development. The goal of this dissertation is to investigate the variability of social interactions over time and how it …

Measuring Development Across The Rural Urban Continuum In The United States Northern Rocky Mountain Region, Morgan E. Anderson

Graduate Student Theses, Dissertations, & Professional Papers

In recent years, the U.S. Northern Rocky Mountain Region has undergone a broad shift in landscape resulting in previously working agricultural, forestry, or other natural resource-based lands transitioning into residential and commercial development. Sprawl, exurban development, loss of crop and forest land have been identified as development concerns in the region. The region is unique because it is generally comprised of smaller metropolitan and micropolitan centers and highly dispersed rural towns making haphazard development issues a concern across the rural‑urban continuum. To identify and describe shifts in development patterns from 2001 to 2016, structural landscape metrics were used to measure …

Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett

Graduate Student Theses, Dissertations, & Professional Papers

The brain is organized as a complex network of specialized neurons that communicate via a combination of electrical and chemical signals. Our brains function to generate movement, control organ function, or direct complex behaviors; all of which requires the ability to regulate the flow of communication between circuits and networks. Work in this thesis addresses two areas of neuron communication: first, how does the release of more than one neurotransmitter from a single neuron impact behavior, and second, are matricellular proteins (MCPs) key contributors to synaptic transmission and neuron function? The conserved CCN family of MCPs have a …

The Genetic Mechanisms Underlying Pigmentation And Their Evolutionary Importance In Birds, Nicholas David Sly

Graduate Student Theses, Dissertations, & Professional Papers

Integumentary pigmentation is a phenotype of fundamental importance to animals, with major impacts on survival and fitness. Thus, understanding the mechanisms underlying pigmentation can help illuminate general principles about how adaptive variation is generated and maintained in populations. Here, I present a dissertation that is aimed at understanding the developmental, regulatory, and genetic mechanisms that underlie variation in avian plumage color, and their evolutionary importance.

In my first chapter, I addressed how the modular organization of plumage traits may impact their evolution. The production of color in developing feathers is a modular process, with several mechanisms combining to produce the …

Rates Of Water Loss And Metabolism In The Eggs Of Stick Insect Eurycantha Calcarata, Garret K. Jolma

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The thorny devil stick insect (Eurycantha calcarata) of New Guinea has eggs that take four months or more to develop—incredibly long for an insect. Long development times can be a challenge for eggs because of their finite resources, including nutrients, energy to support development, and water. I investigated the physiological mechanisms underlying long development times in stick insect eggs.

The first experiment examined rates of water loss and survival of eggs held in different experimental humidities (0, 75, or 100% RH). Eggs dried quickly in the 0% humidity “dry” container; and more slowly in the 75% humidity “intermediate” …

How Does The Million Baht Village Fund Impact Fertility In Thailand?, Kaci Felstet

Graduate Student Theses, Dissertations, & Professional Papers

This study evaluates the impact of Thailand’s Million Baht Village Fund program on household fertility decisions. Thailand’s fertility rates are alarmingly low and it is imperative to recognize the unintended consequences a microfinance program may have on fertility choices within Thailand. Using panel data from pre- and post-program years, this research identifies the change in number of babies in a household associated with getting a microloan from the Village Fund program. The quasi-experimental nature of the program and an instrumental variable model with fixed effects identifies a negative relationship between the number of babies within families and participation in the …

An Outlay Equivalence Analysis Of South African Households, Samuel Peevey

Graduate Student Theses, Dissertations, & Professional Papers

A significant amount of evidence suggests that gender inequality in the developing world negatively impacts women and girls’ health, education and future wage potential. This thesis investigates whether households in South Africa discriminated against their girl children, in favor of their boy children. Additionally, I will investigate whether household heads favored children matching their own sex. Using the 1^st wave of the National Income Dynamics Study and Angus Deaton’s outlay-equivalence ratio method, I will estimate the impact, 8 age and sex categories have on their household’s adult goods expenditure. I found statistically significant but practically insignificant evidence, from a …

Moving Toward A Holistic Menstrual Hygiene Management: An Anthropological Analysis Of Menstruation And Practices In Western And Non-Western Societies, Sophia A. Bay

Graduate Student Theses, Dissertations, & Professional Papers

Educating girls is not only their human right, but also proposed as one of the best investments for improving quality of life in developing countries (Montgomery et al. 2016, 2). Although menstruation is a universal, biological process, it is fraught with cultural stigmas and taboos throughout Western and non-Western societies. Menstrual-related absenteeism is believed to be a primary cause of missed attendance and early dropout rates, so the developing field of menstrual hygiene management (MHM) is seeking to understand and evaluate what factors are contributing to these findings. After the analyzation of the current literature, a more holistic, nine-pronged approach …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough

Graduate Student Theses, Dissertations, & Professional Papers

Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania. In …

Seasonal Dimorphism In Gastropod Hatchling Size: What Can We Learn From Egg Mass Morphology And Deposition Site Conditions?, Lily A. Harrison

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Egg size is one of the most important features of marine invertebrate reproduction because it provides insight into developmental patterns, offspring size, and adult investment per offspring. Intraspecific variation in egg size and the resulting hatchling size may depend on many factors including environmental and maternal conditions and geographic location. Therefore, both the season in which eggs are laid and the spatial heterogeneity of deposition sites may influence egg size and hatchling size. Natica chemnitzii deposits egg masses on sandy beaches along the coast of the Bay of Panama. During the wet (non-upwelling) season hatchling size is unimodal. However, monthly …

Pristine Places And Passive People? Responses To Neoliberal Development And Maoist Conflict In Nepal's Northwest Himalayas, Catherine Lee Sanders

Graduate Student Theses, Dissertations, & Professional Papers

In Humla District, Nepal, agro-pastoralists' confrontations with forces of change in the last generation have altered villagers' abilities to gain access to scarce resources. Development efforts and Nepal's recent armed conflict, in particular, introduced novel technologies and ideologies that affected Humli vulnerabilities. This dissertation is based on field research comparing two Hindu villages in northwest Nepal during 2009 and 2010. One village had more extensive ties to development than the other, and these villagers and other change agents co-created transitional contexts of vulnerability in the post-conflict setting of rural Nepal. An armed conflict dominated the political landscape in Nepal for …

Developmental Stress In Birds: Phenotypic And Fitness, Ondi L. Crino

Graduate Student Theses, Dissertations, & Professional Papers

The environment animals experience during development can have important effects on phenotype, performance, and fitness across multiple life-history stages. Environmental cues experienced during development can provide information to animals about the environment they will soon inhabit and promote phenotypic changes which affect fitness. Increasing evidence suggests that physiological stress may be one such cue that conveys environmental information to developing animals. Here, I explore the short- and long-term consequences of developmental stress in captive and free-living birds. In chapter one, I explore the effects of developmental stress on body size and physiological stress responses across life-history stages in zebra finches …

The Development Of An Artist, Lori Jean Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

The goal of my final creative project was to receive instruction in the area of the visual arts, create a body of work that would be displayed in an art gallery or other appropriate setting, and emerge publicly as an artist. This goal was important to me for two reasons. The first reason was that for many years I had suppressed my own need to create and express myself through art for various reasons: lack of instruction and fear of stepping out of the box and expressing myself creatively. My final creative project has led to an awakening of my …

Decomposing The Increase In Reported Levels Of Subjective Well-Being In South Africa From 1993 To 1998, Benjamin Fitch-Fleischmann

Graduate Student Theses, Dissertations, & Professional Papers

Reported levels of household life satisfaction, also referred to as subjective well-being, increased dramatically in South Africa following the end of Apartheid. This study uses household surveys from 1993-1994 and 1998 in South Africa to investigate why. Models of subjective well-being are estimated following previous literature and a Oaxaca decomposition is then applied, which allows subjective well-being and the determinants of subjective well-being to be examined in a new framework. The decomposition determines what portion of the life satisfaction increase in South Africa is due to improvements in living conditions and what portion is due to changes in the way …
