Rooted In Environmental Justice: Phytogeography And Ethnoecology Of Serianthes, Else Demeulenaere

Biological Sciences

Serianthes Benth. (Fabaceae) is one of the most endangered plant genera in the world, with 12 of the 18 species listed on the IUCN Red List of Threatened Species. Serianthes trees are culturally important to island communities of the Indo-Pacific region for canoes, boats, traditional houses, and medicine. Habitat loss and ecosystem degradation increased pressure on these trees, also threatening its Indigenous cosmology and traditional practices. This interdisciplinary study integrated genomic, biogeographic and ethnoecological approaches to develop appropriate policies that protect the Indigenous biocultural diversity of Serianthes. Phylogenomics of 401 nuclear exons and non-coding flanking regions using both a multi-species …

An Examination Of Bone Loss During Space Travel With Differential Gene Expression Analysis, Claudia Vo

Master's Projects

Spaceflight poses many risks to human health due to the harsh conditions of microgravity, cosmic radiation, and confinement. One of the impacts that spaceflight entails is bone loss, which is a risk to astronauts as future space missions will require long travel durations. To elucidate the role of genetics in spaceflight bone loss, in this study differential gene expression analysis was performed using Nextflow-RCP, an adaptation of NASA Genelab’s RNA-Seq Consensus pipeline. The dataset for this project was GLDS-241, which contained samples from mice femoral skin. To gain a comprehensive understanding of the genes involved in bone loss, the results …

Naturally Occurring Etiologic Factors Affecting The Health Of Breeding Seabirds In The Bering Sea, Maile Branson

Biological Sciences

Seabird populations across the globe have experienced both significant instability and consistent overall declines in recent history. Seabirds in the Bering Sea of Alaska, USA appear to be severely affected by environmental changes, exhibiting large-scale shifts in behavior and distribution and increases in unusual mortality events (UMEs) in recent years. I analyze a selection of the naturally occurring pathogenic and toxicological factors affecting breeding seabirds in the Bering Sea region using an approach focusing on zoonoses and bioaccumulating toxins. Specimens were collected at three breeding colonies in the Bering Sea in 2018 and 2019, and were evaluated for the presence …

Fasting Status Of Steller Sea Lion Pups, Stephanie G. Crawford

Biological Sciences

Following population declines in species of concern, wildlife managers often seek to identify underlying causes to understand and predict population dynamics for better future management. Often, physiological and/or behavioral metrics are measurable markers of decline, and these are often detectable well before declines are measurable through population surveys. During the 1970's, 80's, and 90's Steller sea lion (SSL; Eumetopias jubatus) populations in the western portion of their breeding range declined by ~85%. Though declines in most regions have since stabilized or exhibited modest recovery, some subpopulations breeding in the Aleutian Islands continue to decline. In contrast, SSL subpopulations in eastern …

Systems And Methods For Scalable Retinal Screening Programs, Jeremy Richard Benson

Computer Science ETDs

This dissertation addresses gaps in artificial intelligence-based computer vision tasks in the medical image processing field. We demonstrate effective methods for standardizing and augmenting digital fundus photographs so that robust convolutional neural network-based systems can perform high-throughput disease classification and generalize to never-before-seen data from novel camera technologies, scaling with the changing hardware landscape, as well as keeping up with vast amount of incoming data from the ever-increasing population. We also tackle the problem of discovering relevant samples in an unlabeled cohort of image data, thus widening the bottleneck to all downstream supervised machine learning tasks.

Who Pays To Clean Up What A Dying Industry Leaves Behind?, Audrey Carleton

Capstones

As the birthplace of oil and gas, Pennsylvania is home to the highest number of orphaned abandoned oil and gas wells in the country — an estimated 300,000 to 500,000 dot the Keystone State, all remnants of a dying industry. These wells emit methane, a potent greenhouse gas, and have, for decades, caused alarm to hundreds of residents, documents obtained in a months-long capstone investigation show. The state is currently plugging 10 to 12 abandoned wells per year, on average, out of hundreds of thousands, in part because it has not collected enough in cleanup funds from producers to fund …

Filling Information Gaps In Milwaukee’S Metcalfe Park Neighborhood, Kynala J. Phillips

Capstones

While in the Craig Newmark Graduate School of Journalism’s Engagement Journalism program, I got the chance to work with residents in Milwaukee’s predominantly Black Metcalfe Park neighborhood and the organizations and people that communicate most frequently with its residents.

During these past 18 months, I have practiced deep listening and slow and engaged journalism to build trust with my community. The goal: to create a product that is useful to the residents of Metcalfe Park.

To accomplish this, I joined a small group of journalists and community leaders to produce a print and SMS neighborhood newsletter titled “North 2 Center” …

Ultrasound Modulation Of Macaque Prefrontal Cortex Selectively Alters Credit Assignment–Related Activity And Behavior, Davide Folloni, Elsa Fouragnan, Marco K. Wittmann, Lea Roumazeilles, Lev Tankelevitch, Lennart Verhagen, David Attali, Jean François Aubry, Jerome Sallet, Matthew F.S. Rushworth

School of Psychology

Credit assignment is the association of specific instances of reward to the specific events, such as a particular choice, that caused them. Without credit assignment, choice values reflect an approximate estimate of how good the environment was when the choice was made—the global reward state—rather than exactly which outcome the choice caused. Combined transcranial ultrasound stimulation (TUS) and functional magnetic resonance imaging in macaques demonstrate credit assignment–related activity in prefrontal area 47/12o, and when this signal was disrupted with TUS, choice value representations across the brain were impaired. As a consequence, behavior was no longer guided by choice value, and …

Otolith Derived Hatch Dates, Growth Rates, And Microchemistry Of Arctic Cod (Boreogadus Saida) Support The Existence Of Several Spawning Populations In Alaskan Waters, Zane M. Chapman

Fisheries

The changing climate in the Arctic is resulting in increased air and water temperatures as well as a reduction in sea ice, affecting native species that evolved to live in the unique habitats of the Arctic Ocean. One species of significant importance to Arctic marine ecosystems is the Arctic Cod (Boreogadus saida), a keystone species that serves as vital prey for many marine mammals, seabirds, and fishes. Arctic Cod have a strong association with sea ice for spawning and for much of their early life history. In the Pacific Arctic, little is known about their early life history, especially with …

The Effects Of Ocean Acidification And Warming On The Metabolic Physiology Of Juvenile Northern Spot Shrimp (Pandalus Platyceros), Jamie Lee Musbach

Fisheries

Northern spot shrimp (Pandalus platyceros) support important commercial, subsistence, sport, and personal use fisheries in Alaska. This species is currently experiencing population declines in Southeast Alaska, mandating fishery closures in previously productive regions. Northern spot shrimp are harvested as adults and declining populations may be a result of limited recruitment into the fishery. Very little is known about the physiology of P. platyceros early life history stages and no known data exists on how early life history stages may be affected by environmental stressors such as ocean acidification (OA) and ocean warming (OW). OA is a result of increased anthropogenic …

Coyote Management In San Francisco, Matthew Greer

Master's Projects and Capstones

As cities in North America grow, coyotes have become progressively more important species in urban ecosystems. Moreover, as coyotes increasingly use these urban spaces, human-coyote conflicts have become more common, creating a need for new management strategies. This paper will explore how the city of San Francisco could create a new coyote management plan for its highly visible coyote population. San Francisco has had a persistent coyote population since the early 2000s (Todd, 2018). Currently, the coyote population is close to 100 individuals and is still growing (J. Young, Presidio Trust, pers. comm.). To explore this topic a literature review …

The Feasibility Of Industrial Wastewater Reuse Onsite In The Tri-City Area, Shayla Bergeron

Master's Projects and Capstones

Industries typically discharge wastewater to a centralized wastewater treatment plant, but given ongoing water scarcity from repeated droughts, onsite wastewater reuse within the industrial facility’s plant is an attractive alternative. However, information on economic and technical feasibility on wastewater reuse onsite is limited. A literature review showed that membrane bioreactors are a promising wastewater reuse treatment technology due to their reduced footprint and high quality produced effluent. A watershed assessment of the Tri-City area was conducted to evaluate future water supply. A case study was then performed on industrial dischargers in the Tri-City area applying this technology. Finally, the costs …

Influence Of Grassland Management And Grazing By Different Farm Animals On Animal Performance And Flora Alterations, W. Jentsch, H.-D. Matthes, A. Admasu, H. Möhring

IGC Proceedings (1977-2023)

The objectives of this study were to test the possibilities of using different farm animals for landscape care on extensive pasture, taking into account their particular performance, and to analyse alterations of the flora in consequence of grazing by different animals and various pasture management. Salers had the highest (836g/d) and Galloways (584g/d) the lowest live weight gain as compared with the other breeds (771g/d). Lambs had higher live weight when grazing together with cattle and horses (mixed grazing) than under one species grazing. The number of legume increased and that of grass decreased. Following 3 years the grazing animals …

Animal Production From Tropical Pastures Renovated By Subsoiling And Fertilization In The Cerrados Of Brazil, Valéria P. B. Euclides, Manuel C. M. Macedo, M. P. Oliveira

IGC Proceedings (1977-2023)

A grazing trial was conducted, to study the effects of fertilization on the maintenance of the productivity of four tropical grasses. The paddocks were subsoiled, and dived into halves: one (LF1) received 400 kg/ha of a fertilizer formula 0-20-20.and the other (LF2) 800 kg/ha of the same fertilizers, in January 1995. Annually, 50 kg/ha of N was applied. The productivity on LF2 pastures was greater than that on FL1 pastures, averaging 520 and 410 kg of liveweight gain/ha/year. A double strategy should be followed to sustain animal production in the savanna: maintain soil P over a critical value of 3.0 …

Orchardgrass Pastures For Early-Weaned Beef Calves, J. C. Waller, H. A. Fribourg, C. Dixon, A. E. Fisher, B. V. Conger

IGC Proceedings (1977-2023)

Orchardgrass (Dactylis glomerata) grown alone or with ladino white (Trifolium repens) and red (T. pratense) clovers, provides a high quality March to June pasture. However, many beef producers have their cows calving in January-March, thus producing offspring that are too young to utilize spring forage well. As an alternative, some producers have their cows bred so that calves are born in autumn (September-November). By spring, these calves are old enough to consume pasture forage. The few earlier studies on early weaning of fall-born calves consist of drylot feeding of high quality hay or concentrates. …

Challenging Solitary Confinement Through State Constitutions, Alison Gordon

University of Cincinnati Law Review

Eighth Amendment jurisprudence has resulted in limited scrutiny of solitary confinement despite the known harms associated with the practice. The two-part test established by the federal courts to evaluate Eighth Amendment claims and limitations on challenging prison conditions under the Prison Litigation Reform Act can make it difficult to establish that solitary confinement is cruel and unusual punishment.

State constitutional challenges to solitary confinement are underexplored. Nearly all state constitutions contain an equivalent provision to the Eighth Amendment’s prohibition on cruel and unusual punishment. State courts need not be bound by federal jurisprudence in interpreting the scope of the state …

Authority, Obedience, And Justification, Michelle Madden Dempsey

University of Cincinnati Law Review

We have a duty to think for ourselves. The law claims authority over us. We have a duty, at least sometimes, to obey the law. Alone, each of these premises is fairly uncontroversial. Combined, they create some intriguing puzzles. Can law’s claim of authority be justified? If so, does justified legal authority entail an obligation to obey the law? If not, are we nonetheless justified, and perhaps even obligated, to act as if such an obligation exists? While this essay is hardly the first to address these questions, it is the first to do so by combining elements of Joseph …

Moby-Dick As Corporate Catastrophe: Law, Ethics, And Redemption, David Yosifon

University of Cincinnati Law Review

Herman Melville’s Moby-Dick serves here as a vehicle through which to interrogate core features of American corporate law and excavate some of the deeper lessons about the human soul that lurk behind the pasteboard mask of the law’s black letter. The inquiry yields an illuminating vantage on the ethical consequences of corporate capital structure, the law of corporate purpose, the meaning of voluntarism, the ethical stakes of corporate fiduciary obligations, and the role of lawyers in preventing or facilitating corporate catastrophe. No prior familiarity with the novel or corporate law is required.

We synthesized N₂O emissions over North America using 17 bottom-up (BU) estimates from 1980– 2016 and five top-down (TD) estimates from 1998 to 2016. The BU-based total emission shows a slight increase owing to U.S. agriculture, while no consistent trend is shown in TD estimates. During 2007–2016, North American N₂O emissions are estimated at 1.7 (1.0–3.0) Tg N yr⁻¹ (BU) and 1.3 (0.9–1.5) Tg N yr⁻¹ (TD). Anthropogenic emissions were twice as large as natural fluxes from soil and water. Direct agricultural and industrial activities accounted for 68% of total anthropogenic emissions, 71% of …

Skin Bacterial Metacommunities Of San Francisco Bay Area Salamanders Are Structured By Host Genus And Habitat Quality., Shannon Buttimer, Obed Hernandez-Gomez, Erica Bree Rosenblum

Natural Sciences and Mathematics | Faculty Scholarship

Host-associated microbial communities can influence physiological processes of macroorganisms, including contributing to infectious disease resistance. For instance, some bacteria that live on amphibian skin produce antifungal compounds that inhibit two lethal fungal pathogens, Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal). Therefore, differences in microbiome composition among host species or populations within a species can contribute to variation in susceptibility to Bd/Bsal. This study applies 16S rRNA sequencing to characterize the skin bacterial microbiomes of three widespread terrestrial salamander genera native to the western United States. Using a metacommunity structure analysis, we identified dispersal barriers for these influential bacteria between salamander …
