Evaluating The Geographic Patterns In Isotopic Composition For Nesting Hawksbill Sea Turtles In The Wider Caribbean By Coupling Satellite Telemetry And Stable Isotopes, Anna Kreiger Apr 2026

Evaluating The Geographic Patterns In Isotopic Composition For Nesting Hawksbill Sea Turtles In The Wider Caribbean By Coupling Satellite Telemetry And Stable Isotopes, Anna Kreiger

Electronic Theses and Dissertations 2020 - Present

Combining satellite telemetry and stable isotope analysis offers a framework for inferring sea turtle foraging habitats when spatial isotopic gradients exist. We evaluated this combined approach using carbon (δ13C) and nitrogen (δ1⁵N) isotope values from critically endangered hawksbill turtles (Eretmochelys imbricata) nesting at Buck Island Reef National Monument, U.S. Virgin Islands (N=31), and Long Island (Jumby Bay), Antigua (N = 31). Nesting females were satellite-tracked to identify foraging areas and sampled for skin tissue, and Empirical Bayesian Kriging was used to generate basin-scale δ13C and δ1⁵N isoscapes. Tracked turtles foraged widely across the Caribbean Basin, including the Greater …


Feeding Strategies And Milking Behavior In Robotic Milking Systems, Katherine M. Kennedy, Elizabeth French, Porter D. Ricks, Emma K. Lundgreen Apr 2026

Feeding Strategies And Milking Behavior In Robotic Milking Systems, Katherine M. Kennedy, Elizabeth French, Porter D. Ricks, Emma K. Lundgreen

Animal, Dairy, and Veterinary Science Faculty Publications

Adoption of automatic milking systems (AMS) in the US are expected to increase rapidly in the coming years driven primarily by a desire to improve labor efficiency and flexibility and decrease reliance on hired labor. As such, feeding and milking strategies to best optimize milk production and economic gains tailored to US dairy production systems are needed. Initially introduced as a method to encourage the cow to visit the AMS more frequently, offered feeds through the AMS provide an opportunity to individualize nutrient needs. Often, a pelleted concentrate is offered through the AMS due to its uniformity and customizable nature. …

Maintaining And Axenizing Live Cyanobacterial Cultures For Bacterial Genome Sequencing, Yufei Wang, Louisa Acquah

SACAD: Scholarly Activities

Harmful cyanobacterial blooms are an

increasing concern in western Kansas, yet the

bloom-forming species in this region remain

poorly characterized. In this study, we

established and maintained axenic

cyanobacterial cultures to support future

genomic and ecological investigations. By

ensuring low contamination levels and stable

growth conditions, this work provides a

foundation for downstream analyses of bloom-

forming cyanobacteria. It contributes to a better

understanding of freshwater ecosystem health

in western Kansas.


Continuous Light And Pinealectomy: Two Models Of Melatonin Deficiency Revealing Distinct Interactions With Vitamin D Deficiency On Blood Parameters, Rebaz Sedeeq Shekh, Ismail Mustafa Maulood Apr 2026

Continuous Light And Pinealectomy: Two Models Of Melatonin Deficiency Revealing Distinct Interactions With Vitamin D Deficiency On Blood Parameters, Rebaz Sedeeq Shekh, Ismail Mustafa Maulood

Polytechnic Journal

Modern lifestyles reduce sunlight exposure and increase artificial light at night, potentially promoting vitamin D deficiency (VDD) and melatonin (MEL) suppression. The two hormones regulate immunity, erythropoiesis, and platelet (PLT) indices, but their combined hematological effects are not well characterized. We investigated the independent and combined effects of VDD and MEL deficiency on leukocyte profiles, erythrocyte indices, and PLT parameters in albino rats using two 12-week models (n = 8/group): continuous light (CL)-induced MEL suppression (Control, CL, VDD, and CL + VDD) and pinealectomy (Px)-induced MEL deficiency (Sham. Px, VDD, Px + VDD). Complete blood counts (CBCs) and inflammation-related ratios …


An Occupation-Based Support Group For Underserved Adults Living With Lymphedema, Amivi Amega Apr 2026

An Occupation-Based Support Group For Underserved Adults Living With Lymphedema, Amivi Amega

Student Capstone Papers

Lymphedema is a chronic condition that can significantly impact physical function, psychosocial well-being, and participation in meaningful occupations. Although traditional management primarily focuses on physical symptom reduction, gaps remain in addressing long-term participation and quality of life, particularly among underserved populations. The purpose of this capstone project was to develop an occupation-based support group manual designed to support both the physical and psychosocial needs of adults living with lymphedema.

This project was informed by a needs assessment and expert feedback from Certified Lymphedema Therapists, enhancing clinical relevance and applicability. The manual integrates principles from the Model of Human Occupation and …


Testing Effects Of Acoustic Propagation, Morphology, And Intrasexual Selection On The Elaboration And Performance Of Song In Bachman’S Sparrows (Peucaea Aestivalis), Hans Kayser Gonzembach Apr 2026

Testing Effects Of Acoustic Propagation, Morphology, And Intrasexual Selection On The Elaboration And Performance Of Song In Bachman’S Sparrows (Peucaea Aestivalis), Hans Kayser Gonzembach

Electronic Theses and Dissertations 2020 - Present

Birdsong is a communication signal shaped by ecological, morphological, and cultural processes. While many songbird species produce relatively simple vocal repertoires, others, such as the Bachman’s Sparrow (Peucaea aestivalis), produce moderately large repertoires with multiple distinct and context-dependent song categories. Despite this complexity, little is known about the major drivers that shape song elaboration in this species. Additionally, it is unclear whether abiotic factors play a significant role in determining how different song types are learned and shared within a population. To better understand how ecological and social pressures shape song variation, I conducted three studies using Bachman’s …


Comparing The Effect Of Varying Concentrations Of Polytetrafluoroethylene On The Length And Fresh Weight Of Salvinia Minima, Talha Islam Apr 2026

Comparing The Effect Of Varying Concentrations Of Polytetrafluoroethylene On The Length And Fresh Weight Of Salvinia Minima, Talha Islam

Caroliniana Undergraduate Research Journal

The increasing usage of fluoropolymer pollution in aquatic environments has increased concerns about the ecological consequences of materials such as polytetrafluoroethylene (PTFE), commonly known as Teflon. In the past decade, the usage of Teflon in American homes across the United States has risen by 37.7%, resulting in large amounts of aquatic pollution due to improper disposal of these harmful substances (Török et al., 2020). Although PTFE is chemically inert, its accumulation in freshwater systems can introduce matter that physically interacts with aquatic organisms. This study examined how varying concentrations of PTFE suspensions affect the growth of Salvinia minima, a …

Dietary nitrate supplementation can improve blood pressure and contractile function of type II (fast twitch) muscle fiber contraction and force production. However, limited data are available for  women and dosing guidelines for women. The purpose of this study is to investigate if nitrate ingestion, provided as nitrate-rich beetroot juice, improves blood pressure and countermovement jumps and cycling sprint performance compared to nitrate-depleted beetroot juice placebo in women. Eight recreationally active women have been assigned in a randomized, double-blind, crossover design to three experimental conditions to receive: (1) 2 x 70 ml of concentrated nitrate--depleted beetroot juice placebo (PL; 0.10 mmol …

Identification Of Covalent Catechin Adducts Of Enoyl-Acp Reductase (Fabi) From E. Coli Using Mass Spectrometry, Francisco G. Atwi, P. M. Joyner, Rustin Ghidari

Seaver College Research And Scholarly Achievement Symposium

Enoyl-ACP reductase (FabI), an enzyme which is inhibited by catechin, is essential for lipid biosynthesis in bacteria (E. coli). Another FabI inhibitor, triclosan, has strong antibacterial effects,1 but overuse can be detrimental to the environment. Flavonoids, a class of dietary compounds, are known to have potent inhibitory effects on FabI and other kinases.2,3,4 Adducts form as a result of the biochemical reaction between flavonoids and cysteine, a modification which can be verified by m/z shifts on the mass spectra.5 Samples of E. coli protein with overexpressed FabI are utilized: the wild type with ordinary primary structure, and mutant type lacking …


Submarine Groundwater Discharge As A Potential Driver Of Bacterial Microbiome Shifts In Nearshore Coral Reef Ecosystems At Black Point, Maunalua Bay, Oahu, Francesca Rasi, Niyam Reddy, Emily Mendoza, Jayla Burson, Florybeth La Valle Apr 2026

Submarine Groundwater Discharge As A Potential Driver Of Bacterial Microbiome Shifts In Nearshore Coral Reef Ecosystems At Black Point, Maunalua Bay, Oahu, Francesca Rasi, Niyam Reddy, Emily Mendoza, Jayla Burson, Florybeth La Valle

Seaver College Research And Scholarly Achievement Symposium

Coral reefs thrive in primarily oligotrophic environments, depending on factors such as temperature and salinity for their stability. While moderate levels of nutrients sustain coral growth, excessive nutrient inputs promote algal blooms which can outcompete corals for space. Over the past century, Maunalua Bay (O'ahu, HI) has experienced dramatic development and increase in population, which has affected the water quality in the nearshore coral reefs of the bay. The main source of dissolved land-based inorganic nutrients in Black Point is submarine groundwater discharge (SGD), which is a chronic freshwater vector that is enriched with nitrates, phosphates, silicates, and more. Because …


Associations Between The Human Breast Microbiome And Immune Genes In Breast Cancer, Luke Pontoriero, Joan Argwings-Kodhek Apr 2026

Associations Between The Human Breast Microbiome And Immune Genes In Breast Cancer, Luke Pontoriero, Joan Argwings-Kodhek

Seaver College Research And Scholarly Achievement Symposium

Breast cancer (BC) affects 1 in 8 women and roughly 50% of breast cancers cannot be explained by environmental or genetic factors. There is growing evidence of the role of the human breast microbiome in breast cancer, but the mechanisms guiding this role are not well understood. The co-evolution of the human microbiome with the immune system represents an interaction between host and microbiome that is understudied with regard to breast cancer pathogenesis. We hypothesized that immune genetic variation is associated with altered abundance patterns of bacterial taxa in BC. We conducted 30X whole genome sequencing on a sample of …
