Beyond Boundaries: Governance Considerations For Climate-Driven Habitat Shifts Of Highly Migratory Marine Species Across Jurisdictions, Bianca S. Santos, Elliott L. Hazen, Heather Welch, Nerea Lezama-Ochoa, Barbara A. Block, Daniel P. Costa, Scott A. Shaffer, Larry B. Crowder

Faculty Research, Scholarly, and Creative Activity

The mobile nature of migratory marine animals across jurisdictional boundaries can challenge the management of biodiversity, particularly under global environmental change. While projections of climate-driven habitat change can reveal whether marine species are predicted to gain or lose habitat in the future, geopolitical boundaries and differing governance regimes may influence animals’ abilities to thrive in new areas. Broad geographic movements and diverse governance approaches elicit the need for strong international collaboration to holistically manage and conserve these shared migratory species. In this study, we use data from the Tagging of Pacific Predators program to demonstrate the feasibility of using climate-driven …

The Impacts Of Recreational Infrastructure On Mammal Use Of Riparian Zones In Northern California Regional Parks, Emily A. Matthews

Master's Theses

Public lands have been important for the protection of riparian habitats; however, many public lands are also used for recreation, which can reduce mammal habitat use. Understanding how mammals are affected by recreation in riparian areas can help guide management decisions. The goal of this research is to understand the effect of recreation on mammal use of riparian habitats in two popular East Bay Regional Parks, Charles Lee Tilden and Wildcat Canyon, and to map the extent of that impact. Cameras were deployed in the riparian areas of a high, moderate, and low development site (Alvarado, Tilden, and Wildcat Canyon) …

Creatine And Depression In Rodents: A Meta-Analysis, Ruchika S. Tirupachur

Master's Theses

Traditional treatments for major depression are based on the monoamine deficiency hypothesis, and they fail to achieve remission in a substantial portion of patients. Newer evidence suggests the pathophysiology of depression is a more complex story, highlighting a need for research in alternative therapies. Mounting evidence shows a linkage between depression and the supplement creatine monohydrate (CRMH). Research in rodent models suggests that CRMH may both alleviate depressive symptoms and enhance the efficacy of standard antidepressants like SSRIs. The following study describes findings from a combined fixed- and random-effects meta-analysis based on four empirical studies investigating the effect of CRMH …

Mammal Response To Wildfire In Redwood Forests In Northern California, Kristine Doerr

Master's Theses

California has historically experienced recurrent wildfires that have shaped many of the region’s unique ecosystems such as coast redwood (Sequoia sempervirens) forests. Redwood forests, particularly old-growth redwoods, are vital habitats for many wildlife species. Still, these long-living, fire-resistant trees are facing altered fire regimes due to fire suppression and climate change. The 2020 CZU Lightning Complex Fire was a consequence of these changes and significantly altered the landscape of the Santa Cruz Mountain region. This study analyzes mammal recovery after wildfire in high and low fire severity locations of the CZU Fire using two camera trap grids. The high-severity grid …

Win-Win Ecology: Can Mosses Promote Dudleya Germination To Restore California Quarries?, Kate L. Worrell

Master's Theses

Human actions directly damage habitat for native plants; restoration ecology facilitates successful plant re-establishment in these environments. Open-pit mines leave behind steep, rocky, and nutrient-deficient habitats that are some of the most degraded ecosystems on the planet. Dudleya or ‘live-forevers’— a genus of native California succulent plants that contains many rare, threatened, or endangered species — grow on rocky cliffs and may create a successful reclamation-restoration story. However, Dudleya germination is poorly understood. Much of the literature on Dudleya cites a single field report suggesting that bryophytes facilitate germination, but no previous experiments have evaluated this proposal. In this study, …

An Assessment Of Anthropogenic Injuries On White Sharks (Carcharodon Carcharias) In Central California, Kaitlyn Yee

Master's Theses

As human activities increasingly impact marine ecosystems, understanding the effects of anthropogenic activity on white sharks is important for their continued conservation. Human-induced injuries are observed in many shark species. Such injuries have been found to have physiological and ecological impacts. Four sites in Central California off the coasts of Aptos, Año Nuevo Island, Southeast Farallon Island, and Point Reyes are all known areas of white shark aggregation with varying levels of human use and protection. Utilizing a vast video database, this study evaluated the effects of natural and non-natural anthropogenic shark injury types across all locations, age classes, and …

Swim Bladder Morphology Influences The Responses Of Nearshore Rockfishes To Barotrauma, Molly K. Alvino

Master's Theses

Rockfishes (Sebastes spp.) are ecologically and economically important fishes in the continental shelf and slope regions of the Eastern Pacific Ocean. All species within the Sebastes genus have a buoyancy organ, the swim bladder, which is sensitive to rapid changes in pressure that occur when fish are caught and brought up to the surface. Although all rockfishes have swim bladders, pressure-related injuries (barotrauma) affect rockfish species differently. I determined whether swim bladder morphology can explain differences in barotrauma among semi-pelagic (Blue and Olive rockfish) and benthic (Gopher and Vermilion rockfish) species that occupy different habitat zones. Seven different swim bladder …

The Effects Of Full-Body Photo-Editing On Female Body Image, Claire E. Mcelhern

Master's Theses

Over the past decade, the use of photo-based social media sites has seen an exponential increase. Although these sites can be beneficial for connecting with others, the editing and modification of images posted to social media has also produced adverse effects on some who use them. The aim of the present study was to assess whether partaking in a full-body photo-editing task would have a significant effect on weight dissatisfaction, appearance dissatisfaction and body confidence, compared to a control condition. Female college participants were first asked about their general Instagram use, and then were given a baseline Visual Analog Scale …

Gait Measurement Descriptions Of Human Tracks, Robert Speiden

International Journal of Missing Persons

Search and rescue missions use a variety of tools to find missing persons, one of which can be visual tracking. Trackers detect, interpret and document information about human contact with the ground. Humans typically move on two feet at various speeds. Movement as an obligate biped leaves a series of footprints that alternates from one side to the other. This pattern of footfalls is rather simple, and the footfalls can be easily divided into descriptive dimensions.

This work summarized published measurements of bipedal gait ground contact points in 70 resources. Four resource types were surveyed including 33 biomechanical gait analysis …

Quantitative Label-Free Digital Holographic Imaging Of Cardiomyocyte Optical Volume, Nucleation, And Cell Division, Herman Huang, Sangsoon Park, Ines Ross, Joseph Moreno, Sheamin Khyeam, Jacquelyn Simmons, Guo N. Huang, Alexander Y. Payumo

Faculty Research, Scholarly, and Creative Activity

Cardiac regeneration in newborn rodents depends on the ability of pre-existing cardiomyocytes to proliferate and divide. This capacity is lost within the first week of postnatal development when these cells rapidly switch from hyperplasia to hypertrophy, withdraw from the cell cycle, become binucleated, and increase in size. How these dynamic changes in cell size and nucleation impact cardiomyocyte proliferative potential is not well understood. In this study, we innovate the application of a commercially available digital holographic imaging microscope, the Holomonitor M4, to evaluate the proliferative responses of mononucleated and binucleated cardiomyocytes after CHIR99021 treatment, a model proliferative stimulus. This …

Applicative Recursion And Nominal Licensing, Yining Nie

Faculty Research, Scholarly, and Creative Activity

Languages with applicative morphology vary in whether their applied arguments can stack, or “recurse.” Focusing primarily on Bantu languages, I argue that the availability of applicative recursion in a given language depends on abstract nominal licensing ⎯in particular, on whether the applicative heads responsible for introducing applied arguments are nominal licensers. Applicative recursion therefore provides a novel diagnostic for the presence of abstract nominal licensing, which is argued to be driven not by Case but by ϕ-feature checking. The proposed approach to applicative recursion provides evidence for the role of abstract licensing in Bantu languages and has implications for approaches …

Healthy From The Start: Co-Designing Sleep, Nutrition And Physical Activity Resources For Young Shiftworkers—Novel Implementation And Evaluation, Alexandra E. Shriane, Sally A. Ferguson, Gabrielle Rigney, Charlotte C. Gupta, Tracy Kolbe-Alexander, Madeline Sprajcer, Cassie Hilditch, Robert Stanton, Matthew J.W. Thomas, Jessica L. Paterson, Jamie Marino, Grace E. Vincent

Faculty Research, Scholarly, and Creative Activity

Introduction: The increasing prevalence of shiftwork among young adults poses significant health risks, primarily due to its disruptive effects on sleep, nutrition and physical activity. Addressing these risks necessitates the development of tailored, evidence-based resources to support these key health behaviours. Participatory research approaches, engaging those with relevant lived experience (i.e., co-design) are a novel and effective approach in developing these resources. As such, the aim of the present study was to explore whether sleep, nutrition and physical activity resources for young shiftworkers could be developed using participatory, co-design approaches and how co-designers would rate both the approaches used and …

A Subcortical Model For Auditory Forward Masking With Efferent Control Of Cochlear Gain, Braden N. Maxwell, Afagh Farhadi, Marc A. Brennan, Adam Svec, Laurel H. Carney

Faculty Research, Scholarly, and Creative Activity

Previous physiological and psychophysical studies have explored whether feedback to the cochlea from the efferent system influences forward masking. The present work proposes that the limited growth-of-masking (GOM) observed in auditory nerve (AN) fibers may have been misunderstood; namely, that this limitation may be due to the influence of anesthesia on the efferent system. Building on the premise that the unanesthetized AN may exhibit GOM similar to more central nuclei, the present computational modeling study demonstrates that feedback from the medial olivocochlear (MOC) efferents may contribute to GOM observed physiologically in onset-type neurons in both the cochlear nucleus and inferior …

American anthropology is engaged in significant self-reckonings that call for big changes to how anthropology is practiced. These include (1) recognizing and taking seriously the demands to decolonize the ways research is done, (2) addressing precarious employment in academic anthropology, and (3) creating a discipline better positioned to respond to urgent societal needs. A central role for ethnographic methods training is a thread that runs through each of these three reckonings. This article, written by a team of cultural, biocultural, and linguistic anthropologists, outlines key connections between ethnographic methods training and the challenges facing anthropology. We draw on insights from …

Detection And Measurement Of Bacterial Contaminants In Stored River Water Consumed In Ekpoma, Imokhai T. Tenebe, Eunice O. Babatunde, Nkpa M. Ogarekpe, Joshua Emakhu, Egbe Etu Etu, Onome C. Edo, Maxwell Omeje, Nsikak U. Benson

Faculty Research, Scholarly, and Creative Activity

This study was conducted in Ekpoma, a town dependent on rainwater and river water from nearby areas because of a lack of groundwater sources, and the physicochemical and bacteriological (heterotrophic plate count [HPC], total coliform count [TCC], and fecal coliform count [FCC]) properties of 123 stored river water samples grouped into five collection districts (EK1 to EK5). The results were compared with regulatory standards and previous regional studies to identify water quality trends. While most physicochemical properties met drinking water standards, 74% of samples had pH values > 8.5. Twenty-seven samples were fit for drinking, with EK4 having the highest number …

Embodied Energy Injustice And The Political Ecology Of Solar Power, Dustin Mulvaney

Faculty Research, Scholarly, and Creative Activity

Solar energy is poised to become a major source of electricity around the world. As deployment rises to terawatts levels, these industries will drive demand for specific materials, natural resources, labor, and lands with solar energy resources reconfiguring socio-ecological relations. Global change from the development of solar power commodity chains includes increased demand for minerals and metals, new places for metallurgy and smelting, shifting workforce flows, occupational safety challenges from extractive industries to semiconductor manufacturing fabs. These new geographies of production could result in increased emissions and effluents from specialty chemical industries, conservation and agricultural land use change, and questions …
