Abundance And Distribution Of An Exceptional Number Of Red-Necked Grebes In Western Lake Ontario During Spring 2019, Ross W. Wood, Shannon S. Badzinski, Barbara A. Campbell, Brigitte Collins, Shawn W. Meyer, Denby Sadler

Ontario Birds

The Red-necked Grebe is a regular spring migrant on the Great Lakes and occasionally observed in very large numbers, particularly along the northwestern shore of Lake Ontario. Aerial surveys were flown to document abundance, distribution and habitat use of waterfowl and conspicuous waterbirds along the Ontario shorelines of the lower Great Lakes. On 7 April 2019, we observed a very large number of Red-necked Grebes, estimated at 12,395 individuals, concentrated in western Lake Ontario. The majority of these birds were located offshore along a 20 km span of shoreline between Frenchman’s Bay (Pickering, Ontario) and Bluffer’s Beach (Scarborough, Ontario). However, …

Feeding Niche Overlap And Segregation Among Three Grouse Species Wintering In Hudson Bay Lowlands Of Northern Ontario, Vernon G. Thomas Oct 2025

Feeding Niche Overlap And Segregation Among Three Grouse Species Wintering In Hudson Bay Lowlands Of Northern Ontario, Vernon G. Thomas

Ontario Birds

The Hudson Bay Lowlands of northern Ontario (comprising tundra and taiga) provide winter habitats for Willow Ptarmigan and Sharp-tailed Grouse as well as Rock Ptarmigan that occasionally fly in from arctic and subarctic regions. Winter food niche segregation/overlap was measured among these three species to investigate potential feeding competition; tamarack and berries were quantified by number and mass in the crops of grouse collected from the vicinity of the former community of Winisk, Ontario (now Peawanuck). All grouse species fed on birch and it was the principal food for Sharp-tailed Grouse. Willow was eaten primarily by Willow and Rock Ptarmigan. …

Molecular Imaging Of The Cochlea, Parveen Bazard, Mikalai Budzevich, Xiaoxia Zhu, Bo Ding, Robert Dana Frisina

USF Patents

A novel method of measuring endocochlear potential and cochlear function in a patient is presented. The method uses nuclear imaging, such as PET or SPECT, with a radiotracer such as 201Tl to visualize any potassium ion loss in the cochlea of the patient which can contribute to auditory disorders such as hearing loss. This non-invasive technique represents a new method for auditory diagnoses by measurement of cochlear properties which can aid in the development of new therapeutics for auditory disorders.


The Taxonomy And Origins Of Folia: A Brief Review, Donald G. Davis, Louise D. Hose, Harvey R. Duchene Oct 2025

The Taxonomy And Origins Of Folia: A Brief Review, Donald G. Davis, Louise D. Hose, Harvey R. Duchene

International Journal of Speleology

All folia demonstrate a few common elements: folia (singular, folium) are planar or sub-planar speleothems, slanting downward and away from cave walls and ceilings, and genetically associated with fluctuating environmental interfaces. They were first identified and named from examples in western USA hypogenic caves but have since been identified elsewhere in the world. Folia shelves are typically composed of calcite and interweave smoothly along sub-horizontal contours. Calcite accretion, both chemical and mechanical from suspended particles, follows water-surface fluctuations to form protrusions in arrays along walls and ceilings where new accretion tends to follow the water-surface downward during descending phases, gradually …

Evolutionary Conservation And The Role Of Foxp2 In Human Speech And Language Development, Keira N. Ballard Sep 2025

Evolutionary Conservation And The Role Of Foxp2 In Human Speech And Language Development, Keira N. Ballard

OneUSF Undergraduate Research Conference

The study of genes offers a crucial understanding in the evolution of species and the many abilities an organism may have, including language. The FOXP2 gene encodes for the protein forkhead box P2, a transcription factor that is active in the development of speech and language during embryogenesis. Several single-nucleotide polymorphisms of this gene in humans have been linked to the speech and language disorder, childhood apraxia of speech, further supporting the gene’s role in human speech and language. The FOXP2 gene is highly conserved across vertebrates, even in species with limited vocalizations. This is particularly true among humans, chimpanzees, …


Insights On Aapeptides As They Relate To Inhibiting The P300 Ch1 Domain, Tyler Lambert Sep 2025

Insights On Aapeptides As They Relate To Inhibiting The P300 Ch1 Domain, Tyler Lambert

OneUSF Undergraduate Research Conference

The HIF-1 pathway helps sustain cancerous tumors by preventing tumor cells from becoming necrotic. The histone acetyltransferase p300 protein is a vital coactivator used in the HIF-1 (hypoxia inducible factor) pathway by binding to subunit HIF-1a. Within our lab we aim to use novel AApeptides as a means of competitively inhibiting the p300 coactivator from binding to the HIF-1a subunit. In order to do this we are specifically studying the protein protein interactions of the CH1 (cysteine/histidine rich-1) domain of the p300 protein as it binds to the C-terminal transactivation domain of the HIF-1a subunit. The p300 CH1 domain is …

Comparison Between Aunp And Tio2np Nanocarriers For The Treatment Of Chronic Obstructive Pulmonary Disease, Andrew Thomas, Vedant Patel, Rohit Borra, Joy Yang Sep 2025

Comparison Between Aunp And Tio2np Nanocarriers For The Treatment Of Chronic Obstructive Pulmonary Disease, Andrew Thomas, Vedant Patel, Rohit Borra, Joy Yang

OneUSF Undergraduate Research Conference

Chronic Obstructive Pulmonary Disease (COPD) is one of the most fatal diseases in the world, leading to lung tissue damage and persistent inflammation. Patients with COPD are typically treated with a bronchodilator and steroids to alleviate bronchoconstriction and inflammation; however, the steroids have limited effects. Inhaled nanomedicine utilizes small agents that facilitate pulmonary-targeted delivery, which improves the absorption and potency of the medication. Over a century ago, Paul Ehrlich proposed the 'magic bullet' theory—targeting diseases precisely while minimizing side effects. Recently, nanomedicine has emerged to support Ehrlich’s theory by fostering nanoparticle drug delivery systems, such as gold (AuNPs) and titanium …


Srgap2c And The Human Mind: A Genetic Key To Cognitive Evolution, Alexis J. Zayas Sep 2025

Srgap2c And The Human Mind: A Genetic Key To Cognitive Evolution, Alexis J. Zayas

OneUSF Undergraduate Research Conference

The SLIT-ROBO Rho GTPase Activating Protein 2C (SRGAP2C) gene is a human-specific ortholog of murine SRGAP2 and paralog of SRGAP2A, playing a pivotal role in cortical development and neural plasticity. Unlike SRGAP2A, SRGAP2C arose through segmental duplications unique to the Homo lineage approximately 3.4, 2.1, and 1 million years ago. These duplication events coincide with the divergence of early Homo species from Australopithecus and the emergence of increased cognitive abilities and tool use. SRGAP2C functions as a dominant-negative regulator of SRGAP2A by inhibiting its activity. This results in delayed synaptic maturation and increased density of dendritic spines, key factors thought …


Evolutionary Optimization Of Biologically-Inspired Mechanistic Input-Output Neural Circuit Models In The Auditory Pathway, Abdul-Malik Zekri Sep 2025

Evolutionary Optimization Of Biologically-Inspired Mechanistic Input-Output Neural Circuit Models In The Auditory Pathway, Abdul-Malik Zekri

OneUSF Undergraduate Research Conference

Understanding how to compute specific functions from neural architecture is a fundamental challenge in neuroscience, with profound implications for artificial intelligence, neuromorphic computing, and neurological health. This study employs evolutionary meta-heuristic algorithms to optimize a mechanistic input-output spiking neural network (SNN) model of the cochlear nucleus, a key circuit in the auditory pathway. The research integrates biologically inspired initialization, iterative optimization, and data-driven validation to explore how connectivity and topology influence input-output relationships in neural circuits. Synthetic input-output spike train pairs for spiral ganglion and bushy cells are generated using a computational model of the cochlear nucleus. SNNs are initialized …

USF Patents

Disclosed herein is a series of helical sulfono-γ-AApeptides that mimic the binding mode of the α-helical HD2 domain of B-Cell Lymphoma 9 (BCL9). As disclosed herein, sulfono-γ-AApeptides can structurally and functionally mimic the α-helical domain of BCL9, and selectively disrupt β-catenin/BCL9 PPIs with even higher potency. More intriguingly, these sulfono-γ-AApeptides can enter cancer cells, bind with β-catenin and disrupt β-catenin/BCL PPI, and exhibit excellent cellular activity, which is much more potent than the BCL9 peptide. Furthermore, enzymatic stability studies demonstrated the remarkable stability of the helical sulfono-γ-AApeptides, with no degradation in the presence of pronase for 24 h, augmenting their …
