The Interactive Effects Of Ocean Acidification, Food Availability, And Source Location On The Growth And Physiology Of The California Mussel, Tharadet Daniel Man

Cal Poly Humboldt theses and projects

Research shows ocean acidification (OA) can have largely negative impacts on marine organisms and ecosystems. Prior laboratory studies show that shelled marine invertebrates (e.g., molluscs) exhibit reduced growth rates and weaker shells when experiencing OA-related stress. However, populations of the critical intertidal mussel species, Mytilus californianus, which experience naturally acidic water due to upwelling in certain parts of Northern California have been observed to have relatively stronger and thicker shells and higher growth rates than those that experience less frequent exposure to upwelling. To address the discrepancies between negative effects of OA exposure in the laboratory and seemingly positive …

Evaluating Current And Future Range Limits Of An Endangered, Keystone Rodent (Dipodomys Ingens), Ivy V. Widick

Cal Poly Humboldt theses and projects

Climate is often considered the single most important factor limiting species’ ranges. Other factors, such as biotic interactions, are often assumed to be included via abiotic proxies. However, differential responses to climate change may decouple these relationships or lead to adaptation to novel environments. Accounting for competition and local adaptation should more accurately describe environmental factors influencing current distributions and increase the predictive accuracy of future distributions. Modeling the endangered giant kangaroo rat (Dipodomys ingens) is an excellent application of these model improvements, as the species range consists of geographically and genetically isolated populations experiencing disparate climatic change. …

The Effects Of Prophylactic Ankle Bracing On Collegiate Women's Basketball Ankle Range Of Motion, Static Balance, And Dynamic Balance, Damian Ignacio Aguilar

Cal Poly Humboldt theses and projects

Ankle braces are often used by athletic trainers across the nation in hopes of preventing ankle related injuries. Since prophylactic ankle braces are widely used and accepted, it is critical to understand the effects prophylactic ankle braces are having on ankle functionality and postural control both in a braced and non-braced state. However, the effects of prophylactic ankle braces over the period of a season has limited research. Thirteen collegiate women’s basketball players, who are required to wear prophylactic ankle braces through a 20-week season, participated in this study. The purpose of this study was to determine the effect of …

Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus

Cal Poly Humboldt theses and projects

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …

Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley

Cal Poly Humboldt theses and projects

Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …

Legacies Of Industrial Contamination: Voices Of Resistance In White Lake, Michigan, Elizabeth A. Revord

Cal Poly Humboldt theses and projects

This research presents a case study of resistance to contamination from three large chemical plants by activists in the communities of Montague and Whitehall located on White Lake, Michigan. Although clean-up efforts have met state and federal guidelines for brownfield and Superfund sites, the people and community of White Lake have continued to be vigilant regarding environmental protection and harbor many concerns regarding their future and redevelopment of sites that are likely still contaminated.

The connection to place and sense of community that the residents of White Lake honor is the foundation of their resistance. Using data collected from semi-structured …

Evidence For The Genetic Basis And Inheritance Of Ocean And River-Maturing Ecotypes Of Pacific Lamprey (Entosphenus Tridentatus) In The Klamath River, California, Keith A. Parker

Cal Poly Humboldt theses and projects

Surveys of genetic variation have improved our understanding of the relationship between fitness-related phenotypes and their underlying genetic basis. However, how this information can be used to inform conservation has been unclear in many cases. The objective of this study was to combine next-generation genetic sequencing with traditional ecological knowledge to evaluate imperiled anadromous Pacific lamprey (Entosphenus tridentatus) and apply the findings to conservation in the context of resolving Native American traditional food security issues. In the Klamath River of California, a previously identified Pacific lamprey ocean-maturing ecotype was distinguished by a relatively advanced maturity of female fish …

The 2016 Election: Conservative Female Voters Agentive, Adversarial And Resolutely Republican, Laura F. Benne Ms

Cal Poly Humboldt theses and projects

In the American General election of 2016, the political discourse in the popular media demonstrated a nationwide expectation that female voters and their allies would elect the first female head of state on election day. As the President and his administration assumed control, many of those who had expected a different electoral result expressed bewilderment after learning that 53% of white, female conservative women chose the Republican male candidate Donald Trump for President. Narratives critical of the voting behavior of conservative women were prevalent. This discourse was informed by a blame and shame paradigm of accusations ranging from racism, lack …

A Comparison Of Community Structure In Regulated And Unregulated Reaches In The Upper Eel River, California, Lara Stephanie Jansen

Cal Poly Humboldt theses and projects

Flow regulation of rivers by impoundments and diversions can reduce hydrological variability. As a result, densities of algae and benthic macroinvertebrates often increase, but many sensitive taxa are lost, causing shifts across the food web. In Northern California, dams that reduce winter peak floods can result in the primary consumer community becoming dominated by grazers that are relatively invulnerable to predation, which can reduce the amount of energy transferred up the trophic levels. The steeper slope of the spring hydrograph recession limb downstream of a dam can also greatly impact instream diversity of periphyton, invertebrates and fish. The dam and …

Stability For A Small Historic House Museum: Drafting A Collection Management Policy For The Trinidad Museum, Alexandra Mackay Cox

Cal Poly Humboldt theses and projects

A museum exists and is defined primarily by its collection. It is therefore important for a museum to manage its collection effectively while preserving it for long-term use. The size and scope of the museum's collection will determine the complexity of its policy. As such, all museums, including small ones, need a well-defined Collection Management Policy (CMP). This policy outlines what and how to collect, defines the development and use of the collection as well as procedures for the care of the collection, the loaning of items and removing of items from the museum's collection. The Trinidad Museum, a small …

Habitats Of Mind: Dhamma, The World, And Mindful Activism, Michael L. Masinter

Cal Poly Humboldt theses and projects

As a Buddhist, teacher, and a graduate student, coming to know the conflicts and misconceptions that stem from partial views and experiences, I have found it difficult to locate where to stand and how to engage. Buddhist teaching and practice (Buddhadhamma) offers a pragmatic approach to an overarching series of questions and a method of practice designed to address them: What is suffering, its origin, its cessation, and the way leading to its cessation? These are the Ariya-sacca, the four noble truths (or four ennobling realities), which can be applied to the arising of suffering anywhere in nature—whether internal (mind/culture) …

Sniffing Out Decomposition: Investigating The Reliability Of Human Remains Detection Dogs, Kristen Marie Nawn

Cal Poly Humboldt theses and projects

Characterizing The Effect Of Cjun On The Expression Of Oct4 Variants And How They Correlate With The Expression Of Genes Associated With Potency And Cell Fate Of Murine Embryonic Stem Cells, Kristine Teague

Cal Poly Humboldt theses and projects

cJun is a transcription factor associated with proliferation and growth. Recent evidence has shown it plays a role in cell fate decision making of embryonic stem cells and correlates with changes in Oct4 expression, an important marker for pluripotency. There are multiple Oct4 isoforms that arise from alternative splicing and alternative translation. Oct4A is the variant most frequently associated with pluripotency, while evidence suggests that Oct4B variants have roles in potency as well as stress responses.

We aimed to study the effect of cJun over expression in murine embryonic stem cells on Oct4 gene expression through two methods: transient transfection …

Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost

Cal Poly Humboldt theses and projects

Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies …

Invisible Adjudication In The U.S. Courts Of Appeals, Michael Kagan, Rebecca Gill, Fatma Marouf

Scholarly Works

Non-precedent decisions are the norm in federal appellate courts, and are seen by judges as a practical necessity given the size of their dockets. Yet the system has always been plagued by doubts. If only some decisions are designated to be precedents, questions arise about whether courts might be acting arbitrarily in other cases. Such doubts have been overcome in part because nominally unpublished decisions are available through standard legal research databases. This creates the appearance of transparency, mitigating concerns that courts may be acting arbitrarily. But what if this appearance is an illusion? This Article reports empirical data drawn …

Engendering Social Justice In First Year Information Literacy Classes, Conrad R. Pegues

Communications in Information Literacy

Information literacy classes are becoming common on college campuses to help first year students learn information search skills necessary for higher education. Free speech debates on some college campuses has bred a level of student activism not seen since the 1960s. Librarians can play a key role formulating positive and informed student responses through First Year Information Literacy (FYIL) classes that focus on information literacy in context of social justice issues of race, gender and free speech.

Understanding Financial Conflict Of Interest: Implications For Information Literacy Instruction, Heather B. Perry

Communications in Information Literacy

Libraries have long existed to assist users in accessing accurate information for their needs. Industry has long been motivated to spread disinformation to promote their industry’s message to the public. Although corporate disinformation techniques perfected by the tobacco industry in the 1950’s were exposed, instead of disappearing they have only grown more influential with the rise of the internet. Many industries from petroleum to pharmaceuticals use scientific research to promote their corporate message and have contributed to harming the public. Users need information literacy (IL) to provide them with the skills they need to critically evaluate information and reject the …

Pathogenic Mechanisms Of Takotsubo Cardiomyopathy Or Broken Heart Syndrome, Devorah Leah Borisute

The Science Journal of the Lander College of Arts and Sciences

Takotsubo Cardiomyopathy (TTC) is a temporary heart-wall motion abnormality with the clinical presentation of a myocardial infarction. Found predominantly in postmenopausal women, TTC most often appears with apical ballooning and mid-ventricle hypokinesis. Often induced by an emotional or physical stress, TTC is reversible and excluded as a diagnosis in patients with acute plaque rupture and obstructive coronary disease. The transient nature and positive prognosis of this cardiomyopathy leaves a dilemma as to what precipitates it. This paper explores the theories of the pathogenesis of TTC including coronary artery spasm, microvascular dysfunction, and catecholamine excess. A thorough analysis of the pathogenesis …
