Using Novel And Traditional Survey Techniques To Monitor Small Mammal Species In Northwestern California, Sydney Mccluskey

Cal Poly Humboldt theses and projects

Small mammal species play a critical role in forest ecosystems contributing significantly to overall forest biodiversity and ecological dynamics. Forest-dwelling species are among the most vulnerable to habitat loss and fragmentation. It is essential to develop efficient techniques for monitoring small mammal populations in forested ecosystems to inform conservation efforts and management plans; yet, monitoring small mammals in these habitats can be particularly challenging due to their size, activity patterns, and frequently nocturnal nature. In this study, I aimed to address two primary research objectives: 1) compare the effectiveness of 3 distinct camera-trap survey techniques (i.e., ground, tree, and tube) …

Characterizing The Beneficial Uses Of The Arcata Marsh Constructed Wetland Treatment System And Wildlife Sanctuary, Andrew S. Wolff

The Arcata Marsh Constructed Wetland Treatment System and Wildlife Sanctuary, located in Arcata California, has been in operation since 1986. Not only has it served as the wastewater treatment facility for the city, it has also provided other beneficial uses such as acting as a sanctuary for bird, mammal, amphibian, and macroinvertebrate species. With facility upgrades currently underway, it has become important to revisit the beneficial uses of the Arcata Marsh. This project aimed to identify and characterize these beneficial uses. Literature review was conducted, and eleven beneficial uses were identified. Existing and newly obtained data were analyzed to characterize …

Diet, Growth, And Survival Of Juvenile Coho Salmon (Oncorhynchus Kisutch) In Off-Channel Restoration Projects In Humboldt Bay Tributaries, Katherine Rose Stonecypher

Cal Poly Humboldt theses and projects

Anthropogenic degradation of off-channel floodplain habitats has contributed to widespread declines in Pacific salmonid populations. These habitats are critical to the survival and growth of juvenile Coho Salmon during their first year of life. Restoring connectivity between mainstem and floodplain habitats could provide juvenile salmonids access to a mosaic of heterogenous foraging opportunities, with important consequences for salmonid growth and survival. I analyzed the diet, growth, and survival of juvenile Coho Salmon rearing in three restored off-channel ponds and adjacent mainstem habitats in Humboldt Bay tributaries to evaluate project performance. Juvenile Coho Salmon diet composition was significantly different among sites …

Assessing The Effects Of Remaining Northern California Kelp Forest Mesopredators On Purple Sea Urchin Abundance, Distribution, And Feeding Activity, Sandra E. Traverso

Cal Poly Humboldt theses and projects

Kelp forests are threatened by regional abiotic and biotic stressors, including overgrazing by sea urchins. On the north coast of California, purple sea urchins (Strongylocentrotus purpuratus) are prolific grazers of kelp and with the regional extinction of their main predator (sunflower stars, Pycnopodia helianthoides), it is unknown whether any remaining mesopredators could exert top-down control of purple urchin populations. Other known predators of purple urchins in northern California include rock crabs, which have been shown to control sea urchin populations in Atlantic urchin barrens and indirectly cause phase shifts back to kelp forests. Yet, little is known …

Human Cell Modeling Of Cdkl5-Deficiency Disorder With Patient-Derived Organoids And Hd-Mea, Alyssa Paynton

Cal Poly Humboldt theses and projects

CDKL5 deficiency disorder (CDD) is an X-linked disorder that leads to severe cognitive impairments as well as infantile epilepsy. The only FDA approved therapy helps to reduce seizure frequency, however there are currently no cures approved. While murine models have proven useful in characterizing CDD, there are limitations due to differences in brain structure and development across species that may lead to the reported lack of spontaneous seizures in the mouse, a hallmark in humans affected by this disorder. By the utilization of patient-specific iPSCs generated into cerebral organoids, a more comprehensive and in-depth analysis into rare neurological disorders, such …

Comparative Morphology And Ultrastructure Of Olfactory Epithelia In Plethodontid Salamanders: Effect Of Life History Variation, Emily Gremling

Cal Poly Humboldt theses and projects

Many amphibian species rely on olfaction for locating prey and for social interactions during different life stages. Despite the importance of the olfactory system, research on its structure has been taxonomically limited. The most diverse family of salamanders, the Plethodontidae, has been largely excluded from research efforts to describe olfactory morphology. Although several histological studies have been conducted, no studies have yet looked at morphology at the level of ultrastructure using electron microscopy. The primary goal of my research was to examine olfactory morphology and ultrastructure in plethodontid species with a range of life history strategies, to better understand the …

Using Habitat Modeling To Locate New Populations Of Dunn's Salamander (Plethodon Dunni) Near Its Southern Geographic Range Limit, Mary A. Mackey

Cal Poly Humboldt theses and projects

Habitat suitability models were utilized to direct survey efforts for Plethodon dunni in Northern California. Two models were created, one using traditional statistical methods (GLM or Generalized Linear Modeling) and the other using a machine learning method (MaxEnt or Maximum Entropy modeling). Plots were selected from areas of agreement and disagreement between the models to carry out presence surveys. The MaxEnt model yielded better predictions than the GLM model. The two models had three variables in common (annual temperature range, precipitation of driest month, and precipitation seasonality) and predicted suitable habitat within the known range of P. dunni. The …

A Case Of Incipient Budding Speciation In The California Floristic Province, Infraspecific Divergence In Abronia Villosa, Eli J. Allen

Cal Poly Humboldt theses and projects

Physical barriers to gene flow are the traditional evidence for species divergence. Conversely, there has been increasing acknowledgment of speciation in the face of gene flow as an evolutionary process. Budding speciation involves peripheral populations adapting to local ecological conditions, thereby budding off from a widespread progenitor species. Budding speciation is distinguished by ecological divergence and is generally evidenced by asymmetrical range size and nested phylogenetic relationships of sister species. The narrow endemic Abronia villosa var. aurita is adapted to montane sandy washes adjacent to its widespread sister variety, the desert dwelling var. villosa. Here, I tested the hypothesis …

Assessment Of Avian Community Structure And Habitat Connectivity In The Fanno Creek Corridor Bird Surveys, Habitat Assessment, And Management Recommendations, Grace Hall

Environmental Science and Management Professional Master's Project Reports

Urbanization can significantly impact habitat quality and connectivity for avian communities, decreasing species richness and diversity. However, in highly fragmented habitats, urban parks and riparian zones can provide important habitat corridors for birds that facilitate movement and access to essential resources. On the west side of greater Portland, Oregon, Fanno Creek may serve as a habitat corridor for birds and other local wildlife.

Fanno Creek is a 25-kilometer tributary of the Tualatin River that runs through the cities of Portland, Beaverton, Tigard, and Durham in northwestern Oregon. The land surrounding the creek includes residential, commercial, and industrial properties as well …

Salvation And Sweet Rolls: An Examination Of Mormon Diet Books, Rachel Noorda

English Faculty Publications and Presentations

Religious diet books highlight the overlap between religious and diet cultures. This article examines the intersection of Mormonism, diet culture, and fatphobia through an analysis of Mormon diet books published between 1990 and 2015. The study explores how Mormon diet books leverage the Word of Wisdom (the LDS health code) to promote weight loss and reinforce religious obedience. By framing dietary compliance as a spiritual mandate, these texts link physical health and body size to moral and spiritual worthiness. This conflation of body and spirit, rooted in Mormon theology, amplifies fatphobia by promoting thinness as a sign of obedience and …

“Muchakang Pangkalawakan”: Queering Engagements With Bakla Of The Philippine Tropics, Artemio P. Millo

Sociology & Anthropology Department Faculty Publications

The performance of participants in the Miss Gay Muchakang Pangkalawan [Miss Ugly Gay Universe] in Quiapo, Manila, reflects characteristics of the flamboyant and effeminate bakla. However, these stereotypical depictions may not always be consistent with how participants view themselves. This study argues that an introspective understanding of how participants make sense of their identity work engendered by ever-turning tropes reveals slippages that can liberate them from existing oppressive stereotypes. By utilizing personal narrative and ethnographic reflexivity, this study deconstructs the participants’ performances, revealing identity-making that may reinforce or resist dominant discourses on the bakla under which these narratives are …

An Image Processing Approach For Real-Time Safety Assessment Of Autonomous Drone Delivery, Assem A. Abdelhak, Dan Moss, Alan Hicks, Susan Mckeever

Articles

The aim of producing self-driving drones has driven many researchers to automate various drone driving functions, such as take-off, navigation, and landing. However, despite the emergence of delivery as one of the most important uses of autonomous drones, there is still no automatic way to verify the safety of the delivery stage. One of the primary steps in the delivery operation is to ensure that the dropping zone is a safe area on arrival and during the dropping process. This paper proposes an image-processing-based classification approach for the delivery drone dropping process at a predefined destination. It employs live streaming …

Il-17a Inhibitors For The Treatment Of Psoriasis, Mangesh Bankhele

Electronic Theses and Dissertations

Psoriasis is a long-lasting skin condition caused by the immune system, which is characterized by red, scaly areas. It mainly affects the scalp, elbows, knees, and lower back. Psoriasis, which affects around 2-3% of the world's population, has a substantial influence on the quality of life of people who suffer from it. The disorder arises due to an atypical immunological response in which the immune system mistakenly attacks skin cells, causing fast cell reproduction, inflammation, and excessive growth. Psoriasis can be treated with topical therapies, systemic drugs, and biologics. Topical therapies, including corticosteroids, vitamin D analogs, and retinoids, are commonly …

SchröDinger’S Dissent: The Hybrid Authority Of A Dissenting Opinion, Christina M. Frohock

Marquette Law Review

A dissenting opinion is the Schrödinger’s cat of authorities: both the law and not the law simultaneously. Courts and scholars often clarify that a dissenting opinion is not binding. Outside the universe of precedent, that authority defies easy description. Emerging from the pen of a judge wearing a black robe and acting in an official capacity, a dissenting opinion exhibits the form of the law. Yet, beneath that lofty sheen, a dissent exhibits the substance of commentary. A dissenting judge writes to undercut the law, providing a case law coda. This Article describes the traditional categories of authority, primary and …

Changes In Flanker Task Performance Following High-Intensity Exercise In Endurance Athletes, Felix E. Cottet-Puinel

Dissertations, Master's Theses and Master's Reports

Executive function performance following acute aerobic exercise can be influenced by multiple variables. However, little is known about the lasting effects of these exercise-induced changes. This study aimed to determine the extent to which exercise intensity impacts executive function. 14 young endurance-trained adults (5 female, 9 male) performed an Eriksen flanker task before and immediately after running high-intensity until failure and isochronal moderate-intensity (~12 min). Pre- to post-exercise-induced changes in reaction time (ms), accuracy (%), and self-reported mental effort (1-9 rating) were analyzed by overall tasks and through tasks subsections. Results showed improvement in reaction time following high- and moderate-intensity …

Southern Animals: Multispecies Encounters In Midcentury Southern Fiction, Kacee M. Mckinney

Electronic Theses and Dissertations

This dissertation expands our understanding of how nonhuman animal figures, symbols, and encounters within southern literature have had ideologically profound impacts on our conceptions of humanity, southernness, and relationality. This dissertation examines prose fiction, including short stories, novellas, and novels, from four influential southern writers—Richard Wright, Carson McCullers, Tennessee Williams, and Flannery O’Connor—who were all actively engaged with representing, critiquing, and expanding American conceptions of the south, the nation, and the ‘human’ at midcentury. With an understanding of southern literature as a rich site for not only regional representation but also broader disruptions of national injustices and ideologies of domination …

Indirect And Direct Pathways Of Migratory Shorebird Effects On Nitrogen Cycling Within Temporarily Flooded Agricultural Fields, Victoria Blocker

Electronic Theses and Dissertations

The global human population continues to grow exponentially, and agriculture will need to become more productive to meet growing food demands. Humans also need clean water and other services that ecosystems provide. This requires future agriculture production to reduce environmental and wildlife impacts through improved efficiencies and best management practices. Migratory shorebirds rely on wetlands throughout North and South America as stopover habitat for rest and refueling during migration. Temporarily flooded farmlands in the Mississippi Delta have proven to be beneficial locations for shorebirds during migrations along the central flyway.

Evaluation Of Male And Female Performance And The Role Of Cerebellar Lesions And Local Aromatase Inhibition In Motor And Cognitive Tasks In The Zebra Finch (Taeniopygia Castanotis), Mathew Joseph Thibodeaux

Electronic Theses and Dissertations

Most studies involving sex differences in songbirds are devoted to song learning and development. However, songbirds, such as zebra finches, are excellent models for studying general roles of steroids on behavior post-brain injury because they have high degrees of adult neuroplasticity and neurosteroidogenesis. The role of estradiol (E2) in recovery of function after neural insults in mammals has been well-studied for decades. Only recently has the role of E2 and aromatase in neuroprotection been examined in songbirds, and our lab is one of the few to study the role of E2 and aromatase in behavioral recovery and the only to …
