Dolphins ‘Orient-Against-Current’: Foraging In Dredged Channels, Eliza M.M. Mills, Sarah Piwetz, Dara N. Orbach

Marine Science

Bottlenose dolphins (Tursiops sp.) are opportunistic foragers with global distributions that utilize diverse feeding tactics based on environmental factors, habitat features, prey behavior, group dynamics, and genetics. We describe a unique foraging tactic regularly observed in the confluence of dredged shipping channels with high anthropogenic disturbance, and explore potential abiotic (temporal, tidal, habitat) drivers of the behavior. A shore-based digital theodolite was used from 2021 to 2022 to observe common bottlenose dolphins (T. truncatus) foraging within a current in a technique we term Orient-Against-Current (OAC). During OAC, dolphins position themselves facing into the flow of a current, swimming at a …

Fisheries Research Report No. 363 : South-West Freshwater Angling: Estimates Of Participation, Effort And Catch For 2024/25, Claire B. Smallwood, Karina L. Ryan, Eva Lai

Fisheries Research Reports

South-West Freshwater Angling (SWFA) in Western Australia is a licensed fishery primarily targeting the Brown Trout (Salmo trutta) and Rainbow Trout (Oncorhynchus mykiss), which are stocked in selected dams and rivers, as well as the introduced Redfin Perch (Perca fluviatilis) and the native Freshwater Cobbler (Tandanus bostocki). Since 2000/01, annual phone-recall surveys have been undertaken using the SWFA licence database as the sampling frame. This monitoring provides information to understand the fishery and support future management decisions. For the first time, data are reported by basin for different waterbody types (public dams, rivers) as well as for specific key fishing …

Losing Control: Evaluative Access And The Limits Of Attributability In Angela Smith’S Theory Of Moral Responsibility, Henry Kissam

Honors Theses

The unwilling addict agent archetype–who wholeheartedly resolves to abstain from taking a drug but takes it regardless–is important to moral responsibility theorists for many reasons, but two in particular stand head-and-shoulders above the rest. The first is the frequency with which the archetype must be reckoned with through our everyday practices of moral assessment. It is not an idle thought experiment, pushing nothing but the theoretical limits of a particular theory. It is a near-ubiquitous presence in real, practical moral assessment. The second reason is a consequence of the first. Because we deal with the archetype frequently, we morally assess …

Prevalence Of Cytauxzoon Felis In Ticks From South-Central Kansas And Northwest Arkansas, Nicole E. Mcilvain

Animal Science Undergraduate Honors Theses

Cytauxzoon felis is a protozoan that causes an often-fatal illness in felines known as cytauxzoonosis, or bobcat fever. Ticks are vectors of this pathogen, with Amblyomma americanum being the most common vector. Previous studies have noted a correlation between peak tick season and peak cytauxzoonosis diagnosis. For cytauxzoonosis, minimal treatments exist, and scientists have not found a cure, which is why focus needs to be on preventing disease. Knowledge on the prevalence of C. felis in different tick species helps veterinarians and pet owners be aware of the potential for their cat developing cytauxzoonosis if one or more ticks are …

Dietary inclusion of seaweed in ruminant diets has been studied for more than 5 decades. Early research in seaweed focused primarily on potential health benefits, but recent interest has shifted the paradigm for its use as a nutritional tool to mitigate greenhouse gas emissions. As new seaweeds are identified for their ability to reduce gas emissions, the pendulum will swing once more to understand the impact seaweeds have on ruminant health and production. The overall objective of this dissertation is to investigate digestibility and fermentation, as well as alterations in metabolic and mineral status in ruminants fed various seaweed species. …

Evolution Of Regulatory Pathways In Vibrio Fischeri Strains Impacts Biofilm Phenotypes And Symbiotic Capacity And Curriculum Interventions Differ In Their Impact On Microbiology Utility Value In Nursing Students, Jennifer Calawa

Doctoral Dissertations

Vibrio fischeri strains vary in their capacity to form mutualisms with animal hosts such as the Hawaiian bobtail squid Euprymna scolopes, yet these differences are often not explained by phylogeny. Successful colonization requires biofilm production, which is tightly controlled by a complex network of two-component system regulators including hybrid histidine kinases BinK and RemK, as characterized in the model symbiont strain ES114. Divergence in biofilm network architecture or regulatory logic may lead to strain-specific differences in biofilm formation, limiting symbiotic potential. Part I of this work investigates genetic divergence underlying reduced colonization capacity in strain H905, a planktonic isolate and …

Focal Engine combines the accessibility and rendering performance of game engines with the data handling capabilities and analytical tools of scientific visualization platforms. The engine's capabilities are validated through multiple applications and projects, for example: HabiCAT 3D performs 3D complexity measurements on ocean floor …

Development And Characterization Of Bulk Dsdna-Based Materials Using Biologically Derived Plasmid Dna, Wynter Amythyst Paiva

Doctoral Dissertations

Double-stranded DNA (dsDNA) exhibits many unique sequence-independent properties that remain underutilized in materials science. The exceptional length, solubility, biocompatibility, imageability, molecular recognition capabilities, and topological control of DNA makes it an ideal candidate for the creation of bespoke biomaterials and investigation of fundamental relationships in polymer physics. Unfortunately, translation of DNA-based materials from the microscale to macroscale has been hindered by source constraints and limitations in chemical modification of biologically derived DNA. This work seeks to expand the utility of dsDNA from the benchtop to real world applications. Establishing dsDNA as a commodity polymer will aid in the development of …

Adrift: The Influence Of Shelf Circulation And Larval Dispersal On Coastal Biogeography At Basin And Global Scales, Will Lush

Doctoral Dissertations

The dispersal of larvae plays an important role in determining the distribution of benthic meroplanktonic organisms in the coastal ocean. The work presented in this defense uses biophysical modeling approaches to examine the interaction of larval dispersal with coastal circulation and the impact of these interactions on contemporary coastal biogeography at global scales.I begin by presenting a novel method for validating numerical dispersal estimates against drifter observations from the Global Drifter Program. We find that median dispersal estimates match observations to within 5 percent, while model estimates underpredict the spread of drifters around this median by between 30 and 50 …

Gene Expression Reveals The Pancreas Of Aselli As A Critical Organ For Plasma Cell Differentiation In The Eurasian Common Shrew, William R. Thomas, Cecilia Baldoni, Tanya M. Lama, Yuanyuan Zeng, Angelique P. Corthals, Dominik Von Elverfeldt, John Nieland, Dina K.N. Dechmann, Liliana M. Dávalos

Biological Sciences: Faculty Publications

Background: Almost all mammals rely on the thymus and bone marrow to generate and differentiate B and T cells essential for adaptive immunity. A few members of the family Soricidae, or true shrews within Eulipotyphla, have also evolved an enlarged pancreas of Aselli, a kidney-sized organ hypothesized to serve this primary immune role, and whose gene expression profile is unknown. Results: Here we introduce transcriptomes of juvenile Eurasian common shrews (Sorex araneus, family Soricidae) pancreas of Aselli. We compare these to those of the shrew spleen and chick bursa of Fabricius, an analogous, bird-specific organ, and explore differential expression overlaps …

Regional Analysis Changes In The Salt Marsh: How The Past Is Influencing The Present, Elizabeth May Gorrill

Master's Theses and Capstones

Salt marshes are critical coastal wetlands that provide valuable ecosystem services including coastal erosion control, carbon sequestration, water quality improvement, fisheries habitats, and recreational and economic opportunities for coastal communities. To better understand salt marshes and the changes occurring within the systems due to environmental and human factors, monitoring of established sites is conducted to look at variables such as vegetation cover, elevation, fauna, and vertical accretion. Methodological differences amongst monitoring efforts can result in data that has differing implications when analyzed and interpreted, so documentation of protocols (and any deviance from them) is imperative when bringing together datasets. The …

Energy Assimilation And Thermoregulatory Behavior In Populations Of A Vertebrate Ectotherm (Sceloporus Consobrinus) Along A Geographic Thermal Gradient, Brandon Wolfsohn

Biology Theses, Dissertations, and Student Creative Activity

Ectothermic organisms make up a vast majority of animal species and fill many vital roles in ecosystems due to their prevalence. Because ectotherms are inherently affected by the thermal environment, they are severely impacted by environmental issues such as climate change and other human driven processes that may affect thermal habitats. To better understand how ecosystems are affected by changes in climate, we need a greater understanding of how ectothermic organisms respond and adapt to altered environmental temperatures. This study aims to understand some of the adaptational differences between populations of a widespread lizard species, Sceloporus consobrinus, that inhabit a …

A Scoping Review Of Maternal Active Smoking During Pregnancy And Low-Birth Weight, Naomi Sondang, Nindi Oktavia, Qorinah Estiningtyas Sakilah Adnani, Lani Gumilang, Hadi Susiarno, Victor Abiola Adepoju

Journal of Asian Midwives (JAM)

Background: Low-birth weight (LBW; < 2.5 kg) infants are at increased risk of early mortality, impaired growth, neuro-developmental delay and chronic disease later in life. Maternal behavior, especially cigarette smoking, remains one of the most modifiable determinants of birth weight. We therefore synthesized recent evidence on the association between active maternal smoking during pregnancy and LBW.
Methods: Following PRISMA guidance, we systematically searched PubMed, Scopus and ScienceDirect for the period January 2020 to 31 January 2025 for English-language observational studies that quantified the relationship between active prenatal smoking and LBW. Risk of bias was appraised, and findings were summarized narratively.
Results: In total 26,650 papers were found and eight eligible studies (four cohort, three cross-sectional, one case-control) from Asia, Europe and the Middle East were included. Across all designs and exposure metrics—self-report, exhaled carbon-monoxide, urinary cotinine, and cord-blood DNA-methylation, active smoking was consistently associated with …

Degradation Of Cobalt Chrome Molybdenum Hip And Knee Implants In Vivo And In Vitro, Peter William Kurtz

All Dissertations

Cobalt Chrome Molybdenum (CoCrMo) remains a popular material choice for femoral condyles in total knee arthroplasty and for acetabular liners in dual mobility total hip designs. CoCrMo has been phased out of conventional THA designs due to its correlation with adverse effects such as ALTR and ALVAL. It is less understood if the mechanisms (i.e. abrasive wear to the surface of the implant) that release metal ions into the surrounding tissue occur at similar rates as seen in conventional THA. Additionally, it is unknown what effect the secondary damage modes such as electrocautery damage and adhesive wear have on these …

Root Analysis Of Glechoma Hederacea, Austin Z. Shiner

Theses/Capstones/Creative Projects

Glechoma hederacea, or commonly referred to as ground ivy, is a weed that can be found in many places such as parks, yards, and landscapes. A mutant genotype of Glechoma hederacea that was exhibiting virescence was collected from a single mutant branch of the wildtype ground ivy. The collected mutant has delayed chloroplast development, and this appears to impact plastidial terpenoid synthesis resulting in damage to leaf tissue. Since a range of plant hormones include isoprene units, altered IPP synthesis may have visible impacts beyond the green tissues of the plant, so this study aimed at addressing this question. …

Exploring Differences In Outcomes For Boys Vs. Girls In Parent-Child Interaction Therapy With Toddlers: Results From A Community Sample, Reese Norbie

Psychological Science Undergraduate Honors Theses

Parent-Child Interaction Therapy with Toddlers (PCIT-T) is an early intervention designed to address behavioral and emotional dysregulation in very young children by strengthening caregiver-child relationships and improving parenting strategies. Although previous research has identified sex differences in childhood behavioral and emotional presentations, little research has examined whether boys and girls differ in outcomes following PCIT-T treatment, especially with it being relatively new. The current study explored demographic differences, protective factors, and treatment outcomes among boys and girls receiving PCIT-T in a United States community sample. Participants included toddlers and caregivers receiving services from trained PCIT-T clinicians across the United States. …

Conceptual Gerrymandering In Sffa And Some Thoughts On How It Enables The Case’S Weaponization, David Simson

Buffalo Law Review

This Article makes two main contributions at the intersection of Constitutional Law and critical analyses of race and racial (in)equality. First, and more narrowly, the Article provides an in-depth analysis and critique of the Supreme Court’s most recent affirmative action decision in Students for Fair Admission v. Harvard (SFFA), specifically with respect to a crucial aspect of the case that has not been addressed in depth in other scholarship on the decision: how key opinions conceptualize “race” in their reasoning. The Article shows how the SFFA majority opinion and a concurring opinion by Justice Gorsuch incorporate multiple, and inconsistent, understandings …

Exercise As A Treatment For Depression And Anxiety Symptoms In College Students, Ashley J. Fountain

ATU Honors Projects

Anxiety and depression have become increasingly prevalent among college students, with rates rising to levels that demand urgent and accessible treatment alternatives. Traditional interventions such as psychotherapy and pharmacological treatments, while effective for many, present limitations including high cost, side effects, and barriers to access.
