Subglacial Meltwater Supported Aerobic Marine Habitats During Snowball Earth, Maxwell A. Lechte, Malcolm W. Wallace, Ashleig Van Smeerdijk Hooda, Weiqiang Li, Ganqing Jiang, Galen P. Halverson, Dan Asael, Stephanie L. Mccoll, Noah J. Planavsky

Geoscience Faculty Research

The Earth’s most severe ice ages interrupted a crucial interval in eukaryotic evolution with widespread ice coverage during the Cryogenian Period (720 to 635 Ma). Aerobic eukaryotes must have survived the “Snowball Earth” glaciations, requiring the persistence of oxygenated marine habitats, yet evidence for these environments is lacking. We examine iron formations within globally distributed Cryogenian glacial successions to reconstruct the redox state of the synglacial oceans. Iron isotope ratios and cerium anomalies from a range of glaciomarine environments reveal pervasive anoxia in the ice-covered oceans but increasing oxidation with proximity to the ice shelf grounding line. We propose that …

Seed‐To‐Seedling Transitions Exhibit Distance‐Dependent Mortality But No Strong Spacing Effects In A Neotropical Forest, Philippe Marchand, Liza S. Comita, S. Joseph Wright, Richard Condit, Stephen P. Hubbell, Noelle G. Beckman

Biology Faculty Publications

Patterns of seed dispersal and seed mortality influence the spatial structure of plant communities and the local coexistence of competing species. Most seeds are dispersed in proximity to the parent tree, where mortality is also expected to be the highest, because of competition with siblings or the attraction of natural enemies. Whereas distance‐dependent mortality in the seed‐to‐seedling transition was often observed in tropical forests, few studies have attempted to estimate the shape of the survival‐distance curves, which determines whether the peak of seedling establishment occurs away from the parent tree (Janzen–Connell pattern) or if the peak attenuates but remains at …

The Missing Mirror: A Critical Content Analysis Of Multicultural Children's Literature With Black Male Characters, Wendy Harris

Doctor of Education in Educational Leadership Dissertations

Education in America is facing many challenges, such as the adoption of common core standards and the demand for highly qualified teachers (Darling-Hammond, 2010). Further, the achievement gap lingers on, with Black males often performing poorly on national assessments of reading proficiency (Tatum, 2005). Although Black males are highly literate, they may feel alienated from traditional school systems and classroom reading selections (Kirkland, 2013). One of the most effective strategies for teachers to bridge the gap in reading is to inspire Black males to get engaged with their books and read for longer periods of time. However, children are more …

Host-Parasite Ecophysiology Of Overwintering, Don J. Larson

Biological Sciences

To survive extreme winters, parasites must overwinter either in a host, as free-living larvae, or be reintroduced yearly through migratory hosts. This thesis examines interrelations between host parasite overwintering physiology and behavior in Alaska between the trematode Ribeiroia ondatrae and their host, wood frogs (Lithobates sylvaticus). The first chapter examines overwintering physiology and behavior of wood frogs in the field. The second chapter creates a laboratory method for determining physiological responses of wood frogs to environmental transitions from summer to fall. The third chapter examines if and how R. ondatrae survive within a frozen wood frog. Free-living wood frogs investigated …

Validating A Gps Collar-Based Method To Estimate Parturition Events And Calving Locations For Two Barren-Ground Caribou Herds, Joelle D. Hepler

Biological Sciences

In remote landscapes, it is difficult and expensive to document animal behaviors such as location and timing of parturition. When aerial surveys cannot be conducted as a result of weather, personnel or fiscal constraints, analyses of GPS collar movement data may provide an alternate way to estimate parturition rates and calving ground locations. I validated two methods (population-based method and individual-based method), developed to detect calving events of sedentary woodland caribou, on multiple years of data for two different migratory barren-ground caribou herds in Alaska, the Porcupine and Fortymile herds. I compared model estimates of population parturition rates, individual calving …

Foliage And Winter Woody Browse Quality Of An Important Salix Browse Species: Effects Of Presence Of Alder-Derived Nitrogen And Winter Browsing By Alaskan Moose (Alces Alces Gigas), Justin Burrows

Biological Sciences

In this study, I examined the relationship between soil nitrogen and winter browsing by moose on the physical and chemical characteristics of Salix alaxensis; specifically stem production, leaf nutritional quality, and stem nutritional quality of tissues produced the following growing season. I measured stem biomass production the 2013 growing season and offtake during the 2013-2014 winter browsing season at 16 sites on the Tanana River floodplain near Fairbanks, Alaska. I revisited the sites the following summer and autumn to assess regrowth and to collect soil, foliage, and stem samples. Browsing intensity and total soil nitrogen were similar in sites with …

Single-Nuclei Rna-Seq On Human Retinal Tissue Provides Improved Transcriptome Profiling, Qingnan Liang, Rachayata Dharmat, Leah Owen, Akbar Shakoor, Yumei Li, Sangbae Kim, Albert Vitale, Ivana Kim, Denise Morgan, Shaoheng Liang, Nathaniel Wu, Ken Chen, Margaret M Deangelis, Rui Chen

Faculty, Staff and Students Publications

Single-cell RNA-seq is a powerful tool in decoding the heterogeneity in complex tissues by generating transcriptomic profiles of the individual cell. Here, we report a single-nuclei RNA-seq (snRNA-seq) transcriptomic study on human retinal tissue, which is composed of multiple cell types with distinct functions. Six samples from three healthy donors are profiled and high-quality RNA-seq data is obtained for 5873 single nuclei. All major retinal cell types are observed and marker genes for each cell type are identified. The gene expression of the macular and peripheral retina is compared to each other at cell-type level. Furthermore, our dataset shows an …

Systems Isomorphisms In Stochastic Dynamic Systems, Rajesh Venkatachalapathy

Dissertations and Theses

The identification of isomorphisms between disparate systems is an important focus of systems science. Such isomorphisms have not only conceptual and pedagogical value to systems science, but they also provide pragmatic value to specific disciplines by suggesting new ways to model familiar phenomena and by serving as reference models that show how even simple models can generate complex behavior. Specifically, this dissertation looks at certain classes of stochastic dynamic systems (SDS) and shows that similar equations can model phenomena in sociology and psychology. In both disciplines, what is modeled by these SDS isomorphisms is a certain type of reliability, defined …

Burnout Among Emergency Physicians Working At A Large Tertiary Centre In Ontario, Rushika Perera, Kristine Van Aarsen, Laura Foxcroft, Rodrick Lim

Journal of Wellness

BACKGROUND: Emergency medicine (EM) is a high-stress specialty. Work related stress and burnout have been reported to negatively impact physician-patient interactions, overall physician mental and physical health, and most importantly, patient outcomes. We assessed the rates of burnout among emergency physicians (EPs) at our centre.

METHODS: A local cross-sectional study to assess burnout among adult and pediatric EPs, fellows and residents was conducted at three Emergency Departments (EDs) at a single institution in Canada. The anonymous online survey encompassed demographics, the validated MBI tool (Maslach Burnout Inventory) and additional questions aimed at identifying determinants of EP burnout. Each respondent’s three …

Breeding French Bulldogs So That They Breathe Well—A Long Way To Go, Eva Marie Ravn-Mølby, Line Sindahl, Søren S. Nielsen, Camila S. Bruun, Peter Sandøe, Merete Fredholm

Animal sheltering

Brachycephalic syndrome (BS) is a pathophysiological disorder caused by excessive soft tissue within the upper airways of short-nosed dog breeds, causing obstruction of the nasal, pharyngeal and laryngeal lumen, resulting in severe respiratory distress. As the prevalence of BS appears to be high among some of the affected breeds, there is an urgent need for breeding efforts to improve the health status of those dogs. In the present study, we evaluated correlations between morphometric and other phenotypic characteristics and BS in a population of 69 French bulldogs from Denmark to identify parameters that could serve as a basis for breeding …

Synthesis And Connection Of Iridium Hydrogen Evolution Catalyst To Chlorella Vulgaris Photosystem I For Light-Driven Hydrogen Evolution, Anna Ramirez

Honors Program Theses and Projects

Hydrogen gas has been shown to be a promising energy source as options other than fossil fuels are being looked at in the face of anthropogenic climate change. It is known that anthropogenic climate change is caused by the production of greenhouse gases being let into the atmosphere, specifically a common reason for this is the burning of fossil fuels for energy. The overall goal of this project is to design a biochemical hybrid system that will be used to make H 2 gas and does not require the use of fossil fuels. Burning hydrogen as fuel produces only water …

Buelow, Daniel R. Colman, Theresa A. Mchugh, Jordan G. Okie, Egbert Schwartz, Cristina D. Takacs-Vesbach, Becky A. Ball, Andrew G. Fountain, Michael N. Gooseff, Joseph S. Levy, Maciej K. Obryk

Biology ETDs

The McMurdo Dry Valleys (MDV) of Antarctica are on the threshold of widespread landscape scale change due to increasing temperature and solar radiation and altered hydrology: buried ice is melting, the soil active layer is thickening, thermokarst features are developing along streams, water tracks are expanding, and lake levels are rising. These changes will impact the microbial communities found in each of the affected habitats. The purpose of this work is to first, understand the spatial distribution of soil bacteria in the MDV, specifically investigating the scale-dependent effects of environmental heterogeneity, and second, to perform surveys and coupled experiments to …

Rising Seas Are Coming For The Dead, Kristen Ancillotti

Capstones

When people think of preparing for a disaster, they focus on how to safeguard homes, prevent damage to roads, and create efficient flood drainage. But as sea levels rise, it’s not only the living that are affected. Coastal cemeteries are washing away or slowly turning into marshland, and in some instances, caskets can be seen floating in the streets after storms. Projections from NOAA indicate that the global mean sea level is likely to rise at least 12 inches by 2100, and in a worst case scenario in which greenhouse gas emissions are at their highest, as high as 8.2 …

Mechanism Of Action Of Htx-011: A Novel, Extended-Release, Dual-Acting Local Anesthetic Formulation For Postoperative Pain, Thomas Ottoboni, Quart, Jayne E. Pawasauskas, Joseph F. Dasta, Richard A. Pollak, Eugene R. Viscusi

Pharmacy Practice and Clinical Research Faculty Publications

Background and objectives Obtaining consistent efficacy beyond 12–24 hours with local anesthetics, including extended-release formulations, has been a challenging goal. Inflammation resulting from surgery lowers the pH of affected tissues, reducing neuronal penetration of local anesthetics. HTX-011, an investigational, nonopioid, extended-release dual-acting local anesthetic combining bupivacaine and low-dose meloxicam, was developed to reduce postsurgical pain through 72 hours using novel extended-release polymer technology. Preclinical studies and a phase II clinical trial were conducted to confirm the mechanism of action of HTX-011.

Methods In a validated postoperative pain pig model and a phase II bunionectomy trial, the analgesic effects of HTX-011, …

The “Active Ingredients” Of Yin, Yang And Neutral Food And The Effect Of These Nutrients On Improving And Maintaining Health, Jingle Xu

Health and Kinesiology Theses

Chinese dietary therapy has been documented to date back at least 4000 years (Zhang, 2012). The aim of traditional Chinese dietary therapy was to maintain health by achieving the balance of Yin, cold or cool, and Yang, hot or warm, components in human bodies through having a Yin-Yang-balanced diet. Yin foods were to expel heat syndromes, such as constipation, caused by excessive Yang (heat), while Yang foods were to treat cold syndromes, such as fatigue, caused by excessive Yin (coldness). However, evidence of this food therapy phenomenon was not clear yet. The purpose of this study was to explore the …

Green Means Go: Tribes Rush To Regulate Cannabis In Indian Country, Julie Kim, Jessica Roberts

American Indian Law Journal

During the Obama administration, the United States Department of Justice (DOJ) issued a series of memos stating that the federal government would not interfere with state laws legalizing cannabis. The United States Attorney General later expressly extended this policy to Indian Country. As a result, tribes began debating potential advantages and disadvantages of participating in the cannabis market. Then, in January 2018, the DOJ rescinded the memos and publicly recommitted itself to prosecuting the possession, cultivation, and distribution of marijuana. Consequently, tribes should approach “The Green Rush” as an exercise of their sovereignty; when a tribe decides to legalize or …

A Self-Marker-Like Protein Governs Hemocyte Allorecognition In Halocynthia Roretzi, Masaki Ema, Taizo Okada, Miki Takahashi, Masato Uchiyama, Hideo Kubo, Hideaki Moriyama, Hitoshi Miyakawa, Midori Matsumoto

School of Biological Sciences: Faculty Publications

Background: Self-incompatibility, fusion/non-fusion reactions, and contact reactions (CRs) have all been identified as allorecognition phenomena in ascidians. CR is a reaction characteristic of the hemocytes of Halocynthia roretzi, whereby they release phenol oxidase (PO) upon contact with non-self hemocytes. Thus, these cells may represent a primitive form of the vertebrate immune system. In the present study, we focused on the CR of H. roretzi hemocytes and sought to identify self-marker proteins that distinguish between self and non-self cells.

Results: We initially generated a CR-inducing monoclonal antibody against the complete hemocyte membraneprotein complement (mAb11B16B10). This antibody was identified based on the …

Nothing Is Over: Ftca Claims For Toxic Torts On Native Lands, Jessica Ditmore

American Indian Law Journal

In 1976, Congress passed the Resource Conservation and Recovery Act (“RCRA”) to curtail the growing problem of disposing of hazardous waste and toxic substances generally. Decades prior, Congress established the Federal Tort Claims Act (“FTCA”) to hold the federal Government liable for tortious conduct the same way a private citizen would be. The federal government assumed the responsibility to ensure the wellbeing of Native Nations (“NN”). This is commonly referred to the “Trust Doctrine.” This duty stems from the settlement of Native American lands, and a recognition of the treaties entered into by the United States with a “moral [obligation] …
