Accelerometry Reveals Hidden Variation In The Movement Response Of Timber Rattlesnakes (Crotalus Horridus) To Roadways, Anna F. Tipton, Morgan L. Thompson, Dominic L. Desantis
Accelerometry Reveals Hidden Variation In The Movement Response Of Timber Rattlesnakes (Crotalus Horridus) To Roadways, Anna F. Tipton, Morgan L. Thompson, Dominic L. Desantis
Graduate Research Showcase
Roadways are among the most widespread and disruptive anthropogenic land use features that influence the behavior and movement of wildlife. Negative impacts including vehicle-induced mortality, habitat destruction and fragmentation, and creating barriers to movement have been well documented across taxa, but the fine scale behavioral impact of roadways on smaller, cryptic species has yet to be directly examined. Using a novel integration of emerging spatial analyses and tri-axial accelerometry, we quantified spatial and temporal aspects of movement and space use in order to investigate the coarse and fine scale influence of roadways on the movement patterns of Timber Rattlesnakes (Crotalus …
A Sweet Way To Increase The Metabolic Activity And Migratory Response Of Wound-Related Cells: Deoxy-Sugar Incorporated Natural Polymeric Fibres As A Potential Bioactive Wound Patch, Serkan Di̇ki̇ci̇
Turkish Journal of Biology
The selection of a wound dressing is crucial for successful wound management. Conventional dressings are preferable for the treatment of simple wounds. However, a bioactive wound dressing that supports wound management and accelerates the healing process is required when it comes to treating non-self-healing wounds. 2-deoxy-D-ribose (2dDR) is a small deoxy sugar that naturally occurs in human body. Although we have previously demonstrated that 2dDR can be used to induce neovascularisation and accelerates wound healing in vitro and in vivo, the literature on small sugars is conflicting, and the knowledge on how 2dDR achieves its biological activity is very limited. …

Joseph Grinnell designed the Natural History of the Vertebrates (NHV) course at the Museum of Vertebrate Zoology, University of California at Berkeley, over 100 years ago and the course has changed little over these years. In this essay, I connect modern pedagogical and cognitive understandings of what we know leads to success among students to the course. This analysis reveals that the course continues to be successful because it has all the elements of a student-centered, active-learning class that leads to better cognitive gains, better retention, and importantly, proportionately better gains for students from underserved populations. This study will be …
Fish Sound Production: The Swim Bladder, Michael L. Fine, Eric Parmentier
Fish Sound Production: The Swim Bladder, Michael L. Fine, Eric Parmentier
Biology Publications
Analogous to the syrinx in birds and larynx in mammals, the swim bladder is a major sound-producing organ in fishes. It also functions in hearing and is responsible for most returns from sonar. Historically, the swim bladder has been modeled as an underwater resonant bubble, whereas we provide evidence for a forced-response model in which viscous damping of the bladder wall inhibits resonance of the internal bubble. Further experimental work on the shape, wall structure, and mechanical behavior of the swim bladder is required.

An Investigation Of Bubble Resonance And Its Implications For Sound Production By Deepwater Fishes, Mark W. Sprague, Michael L. Fine, Timothy M. Cameron
Biology Publications
Although the continental slope and abyss comprise the largest habitat on earth, the absence of documented fish sounds from deep waters is striking. Fishes with sexually dimorphic muscles attached to their swim bladders suggests that sounds are likely used in male courtship on the upper, mid and lower continental slope. To investigate the effects of environmental extremes on fish sound production, the acoustic behavior of a driven bubble is examined. This study is also relevant to target strength of sonar returns from fish and hearing in auditory specialist fishes. A bubble is a classic, if imperfect, model for swim bladder …
The Role Of Ehd2 In Endothelial Cells, Rachael Judson
The Role Of Ehd2 In Endothelial Cells, Rachael Judson
Electronic Theses and Dissertations
The role of EHD2 in terms of Cav1 interaction had not been previously characterized and was the main goal of this research. Cav1 has been shown to lead to the ubiquitination of Rac1. Because of this, the role of EHD2 in Rac1 regulation was investigated. An increase in long-term migration in endothelial cells was observed and suggested that EHD2 impacts the RhoA pathway instead of the Rac1 pathway. This lead to the hypothesis that EHD2 controls a part of the RhoA pathway. This hypothesis is supported by the loss of filamentous actin and an increase in serrated junctions in cells …
Environmental Gradients Impact Key Leaf Traits In Riparian Trees, Amanda Malone
Environmental Gradients Impact Key Leaf Traits In Riparian Trees, Amanda Malone
Electronic Theses and Dissertations
Specific leaf area (SLA) reflects a plant’s carbon investment per area and relates to generalized leaf economics spectrum growth strategies (LES). To fill gaps of knowledge about intraspecific SLA variation and why it is often inconsistent with the LES, we studied the response of two riparian tree species along the urban-rural gradient in Northeastern Colorado: an invasive, nitrogen-fixer with broad tolerances and a nitrogen-limited and shade-intolerant native. Despite these differences, the two species responded similarly, apart from the response to the urban-rural gradient, in which lower nitrogen in rural areas was associated with a more conservative strategy in the native …
Interrelationships Of Systemic Changes In Hepatic Encephalopathy, Els Reuvekamp
Interrelationships Of Systemic Changes In Hepatic Encephalopathy, Els Reuvekamp
Biology and Microbiology Graduate Students Plan B Research Projects
Hepatic encephalopathy is a temporary decline in mental function that is often associated with liver disease and/or portal-systemic disease. Hepatic encephalopathy (HE) symptoms can range from minor cognitive declines to coma and are known to result from excess ammonia accumulations in the blood stream subsequent to liver failure. While HE is known to result from hepatobiliary disorder, many of the physiological process underlying its development and progression remain to be elucidated. Recent studies have identified neurological, metabolic, and microbiome changes implicated in the disease state of HE. In this review, the roles of traditional pharmaceutical interventions and newly developing understandings …
Non-Invasive Biomarkers For The Diagnosis Of Endometriosis And Polycystic Ovary Syndrome, Chandana Kamaraj
Non-Invasive Biomarkers For The Diagnosis Of Endometriosis And Polycystic Ovary Syndrome, Chandana Kamaraj
Biology and Microbiology Graduate Students Plan B Research Projects
Benign gynecological disorders can affect a high percentage of women of reproductive age, ages 15-44 years. These conditions can affect the lifestyle of the individual and can be associated with infertility. The gold standard to identify and diagnose endometriosis requires invasive surgical procedures, while the Rotterdam Criteria is used to identify and diagnose polycystic ovary syndrome. The purpose of this paper is to discuss, describe, and characterize potential non-invasive biomarkers that are present in various pathological stages of both endometriosis and polycystic ovary syndrome. These biomarkers include CA125, Serum galectin-9, hsa-miRNA-154-5p, miRNA-93, miRNA-320 and ET-1, miRNA-222, miRNA-146a, and miR-30c used …

Biology Faculty Publications
Molecular genetic analyses in the model species Arabidopsis thaliana have demonstrated the major roles of different CAM-BINDING PROTEIN 60 (CBP60) proteins in growth, stress signaling, and immune responses. Prominently, CBP60g and SARD1 are paralogous CBP60 transcription factors that regulate numerous components of the immune system, such as cell surface and intracellular immune receptors, MAP kinases, WRKY transcription factors, and biosynthetic enzymes for immunity-activating metabolites salicylic acid (SA) and N-hydroxypipecolic acid (NHP). However, their function, regulation and diversification in most species remain unclear. Here we have created CBP60-DB, a structural and bioinformatic database that comprehensively characterized 1052 CBP60 gene homologs …

Point-Of-Care Diagnosis Of Cervical Cancer: Potential Protein Biomarkersin Cervicovaginal Fluid, Büşra Köse, Özgüç Takmaz, Mete Güngör, Ahmet Tarik Baykal
Turkish Journal of Biology
Cervical cancer (CxCa) is preventable and treatable via vaccination and screening. Cervicovaginal fluid (CVF) represents the physiological components of the female genital tract. These components are suitable to be utilized for clinical purposes, therefore, making CVF a suitable material for disease screening approaches. Due to high false-negative result rates and low attendance of current expensive routine CxCa screening methods, it has become more important to develop a point-of-care (POC) screening method that every single woman could reach worldwide. For this purpose, various self-usage apparatus have been developed for screening of the human papilloma virus (HPV) infection. Furthermore, due to the …
The Isolation And Characterization Of Bacteriophage Hasitha, Gillian Brown
The Isolation And Characterization Of Bacteriophage Hasitha, Gillian Brown
Mahurin Honors College Capstone Experience/Thesis Projects
Microbacteriophage Hasitha is a virus that infects Microbacterium foliorum, a bacterium associated with grasses that was first discovered in Germany. Hasitha was isolated from an enriched compost sample and is of particular interest due to its unusual growth pattern. Most bacteriophages require actively growing host cells to produce new phage progeny. However, Hasitha can infect and kill stationary (non-replicating) bacterial cells. We discovered this unusual characteristic through a fortuitous observation of infected lawns that were allowed to incubate in the lab workspace for approximately one month. During this time, a noticeable “halo” grew around the initial site of infection …

Biology Faculty Research and Scholarship
Aim: Rapid global change is impacting the diversity of tree species and essential ecosystem functions and services of forests. It is therefore critical to understand and predict how the diversity of tree species is spatially distributed within and among forest biomes. Satellite remote sensing platforms have been used for decades to map forest structure and function but are limited in their capacity to monitor change by their relatively coarse spatial resolution and the complexity of scales at which different dimensions of biodiversity are observed in the field. Recently, airborne remote sensing platforms making use of passive high spectral resolution (i.e., …
One Shell Of A Problem: Cumulative Threat Analysis Of Male Sea Turtles Indicates High Anthropogenic Threat For Migratory Individuals And Gulf Of Mexico Residents, Micah Ashford
Masters Theses
Human use of oceans has dramatically increased in the 21st century, with some of the highest rates of change found within the Gulf of Mexico and Caribbean. Sea turtles are particularly vulnerable to anthropogenic stressors in the marine environment as they make lengthy migrations between foraging and breeding sites often along coastal migration corridors. Sea turtles face severe population pressure from humans, yet little is known about how movement and threats interact specifically for male sea turtles. To better understand male sea turtle movement, and the threats they encounter within their expansive ranges, we tagged 40, adult male sea turtles …
Assessment Of Repeatability And Behavioral Syndromes In Genetically Distinct Clades Of Eastern Red-Backed Salamanders (Plethodon Cinereus), Kelsey Garner
Masters Theses
Animal personality implies limited behavioral plasticity and behavioral traits which are correlated across contexts. Correlated behaviors, sometimes referred to as behavioral syndromes, have the potential to inhibit behavioral traits from evolving independently. Limits on behavioral variation can influence a population’s ability to invade new geographic areas and exploit new niches. One way to explore such variation is to examine behavioral syndromes in genetically distinct populations of wide-ranging species that exhibit different dispersal pathways and distances. The personality-dependent dispersal syndrome suggests that certain traits, such as exploratory and risk-taking behavior, are correlated with dispersal success. The Eastern Red-backed Salamander (Plethodon …

Survey Of Diatom Periphyton Assemblages In Lake George, Joy Jackson
Masters Theses
Lake George is an oligotrophic lake that has been monitored by the International Biological Monitoring Program (IBM) since the 1960s. The 51 km long lake is separated into two deep basins, one in the south where the major stream inputs are located, and one in the north where the lake feeds the La Chute River, which empties into Lake Champlain. The two basins are separated by a shallow channel named the “Narrows.” The southern basin has experienced a higher level of development than the northern basin. The aim of this study is to characterize the diatom assemblages in the northern …
An Analysis Of Different Treatment Options For Type 1 Diabetes Mellitus, Ariella Shifteh
An Analysis Of Different Treatment Options For Type 1 Diabetes Mellitus, Ariella Shifteh
The Science Journal of the Lander College of Arts and Sciences
Type 1 Diabetes Mellitus is a highly dangerous autoimmune disease. Type 1 diabetes is most commonly seen in children and young adults as pancreatic Beta (B) cell destruction is highest at this age. Patients with Type 1 Diabetes are required to take insulin injections to compensate for their lack of insulin, but many patients still have episodes of hyperglycemia. This paper analyzes and compares the effectiveness of different treatment options. The standard approach is to prescribe insulin injections, but this analysis finds insulin injections in conjunction with oral medications such as Metformin and Sodium-glucose co-transporter (SGLT) inhibitors has a positive …
Cerebral Organoids As Models For Neurological Disorders, Esther Karman
Cerebral Organoids As Models For Neurological Disorders, Esther Karman
The Science Journal of the Lander College of Arts and Sciences
Despite the devastating effects of neurological disorders on millions of people each year, for decades, brain research remained stagnant in the face of scientific advancement in other areas. Ethical concerns, debilitating costs, and a lack of suitable models created an unfriendly environment for the study of neurodegenerative diseases such as Alzheimer’s disease (AD), Parkinson’s disease (AD), amyotrophic lateral sclerosis (ALS), autism spectrum disorder (ASD), and gliomas. Recent developments in the field of stem cells, including Yamanaka’s discovery of the four transcription factors necessary to induce pluripotency, and the subsequent culturing of induced pluripotent stem cell models known as organoids, opened …

Does The Thermal Mismatch Hypothesis Predict Disease Outcomes In Different Morphs Of A Terrestrial Salamander?, Matthew Venesky, Joseph Alan Demarchi, Cari-Ann M. Hickerson, Carl D. Anthony
2022 Faculty Bibliography
Many aspects of ectotherm physiology are temperature‐dependent. The immune system of temperate‐dwelling ectothermic host species is no exception and their immune function is often downregulated in cold temperatures. Likewise, species of ectothermic pathogens experience temperature‐mediated effects on rates of transmission and/or virulence. Although seemingly straightforward, predicting the outcomes of ectothermic host−pathogen interactions is quite challenging. A recent hypothesis termed the thermal mismatch hypothesis posits that cool‐adapted host species should be most susceptible to pathogen infection during warm temperature periods whereas warm‐adapted host species should be most susceptible to pathogens during periods of cool temperatures. We explore this hypothesis using two …

Sequestration of chemical defenses from dietary sources is dependent on the availability of compounds in the environment and the mechanism of sequestration. Previous experiments have shown that sequestration efficiency varies among alkaloids in poison frogs, but little is known about the underlying mechanism. The aim of this study was to quantify the extent to which alkaloid sequestration and modification are dependent on alkaloid availability and/or sequestration mechanism. To do this, we administered different doses of histrionicotoxin (HTX) 235A and decahydroquinoline (DHQ) to captive‐bred Adelphobates galactonotus and measured alkaloid quantity in muscle, kidney, liver, and feces. HTX 235A and DHQ were …

Hybridization Between The Woodland Salamanders Plethodon Cinereus And P. Electromorphus Is Not Widespread, Shawn R. Kuchta, Maggie M. Hantak, Brian P. Waldron, Cari-Ann M. Hickerson, Richard M. Lehtinen, Carl Anthony
2022 Faculty Bibliography
A recent study reported widespread hybridization between the Eastern Red-backed Salamander (Plethodon cinereus) and the Northern Ravine Salamander (P. electromorphus) in northern Ohio. In this study, DNA sequence data were obtained from three nuclear loci and 20 single nucleotide polymorphisms (SNPs) were identified from the sequences. They found that 48 out of 90 individuals from 13 populations were hybrids, and in some localities every individual possessed an admixed genotype. As these results contradict our observations, and because levels of hybridization impact our interpretation of past and ongoing studies, we revisited the data. First we reanalyzed the original SNPs using STRUCTURE, …

Three novel strains in Calotrichaceae from tropical habitats were isolated and characterized with regard to their morphology, phylogenetic placement, and secondary structures of conserved domains in the 16S‐23S internal transcribed spacer (ITS). The strains fell into two clades formerly identified as Calothrix from freshwater and brackish habitats. Based on both morphology and ecology, they differed from the type species of Calothrix, C. confervicola, which is marine, has wide trichomes with short cells, and narrows abruptly to a hyaline hair. The first clade grouped species with heteropolar filaments widened at the base and narrowed gradually toward the apex but not ending …

Maternal Provisioning Of Alkaloid Defenses Are Present In Obligate But Not Facultative Egg Feeding Dendrobatids, Emily D. Villanueva, Olivia L. Brooks, Sarah K. Bolton, Nina Savastano, Lisa M. Schulte, Ralph Saporito
2022 Faculty Bibliography
Poison frogs sequester alkaloid defenses from a diet of largely mites and ants. As a result, frogs are defended against certain predators and microbial infections. Frogs in the genus Oophaga exhibit complex maternal care, wherein mothers transport recently hatched tadpoles to nursery pools and return regularly to supply developing tadpoles with unfertilized (nutritive) eggs. Developing tadpoles are obligate egg feeders. Further, female O. pumilio and O. sylvatica maternally provision their nutritive eggs with alkaloid defenses, providing protection to their developing tadpoles at a vulnerable life-stage. In another genus of poison frog, Ranitomeya, tadpoles only receive and consume eggs facultatively, and …
Repeatability Of Foraging Behavior Following A Simulated Predation Attempt Depends On Color Morph, Sex, And Foraging Metric In Red-Backed Salamanders (Plethodon Cinereus), Brian P. Waldron, Marissa C. Ganzfried, Cari-Ann M. Hickerson, Carl D. Anthony
Repeatability Of Foraging Behavior Following A Simulated Predation Attempt Depends On Color Morph, Sex, And Foraging Metric In Red-Backed Salamanders (Plethodon Cinereus), Brian P. Waldron, Marissa C. Ganzfried, Cari-Ann M. Hickerson, Carl D. Anthony
2022 Faculty Bibliography
Behavioral repeatability greatly affects the capacity of an individual to respond to varying environments. When multiple behaviors within individuals are repeatable and correlated across time or across contexts, it is termed a behavioral syndrome. However, not all behaviors exhibit the same level of repeatability, and relatively few studies have examined repeatability in amphibians. We examined the repeatability of foraging behavior in the Eastern Red-backed salamander (Plethodon cinereus), a color-polymorphic terrestrial salamander, following a simulated predation attempt. We tested several hypotheses: (1) Simulated predation would negatively affect foraging, increasing latency to feed and decreasing the number of prey items eaten in …
Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Animal Sentience
Crump et al. (2022) offer a well-argued example of an essential development: a rigorous framework for assessing sentience from the perspective of moral concern over an agent’s welfare. Current and forthcoming developments in bioengineering, synthetic morphology, artificial intelligence, biorobotics, and exobiology necessitate an expansion and generalization of this effort. Verbal reports (the Turing Test) and homology to human brains are utterly inadequate criteria for assessing the status of novel, unconventional agents that offer no familiar touchstone of phylogeny or anatomy. We must develop principled approaches to evaluating the sentience of (and thus, our responsibility to) beings of unfamiliar provenance and …

Regulation Of Interferon- Induced Interleukin-8 And Pd-L1 Expression In Ovarian Cancer Cells, Sveta Padmanabhan
Regulation Of Interferon- Induced Interleukin-8 And Pd-L1 Expression In Ovarian Cancer Cells, Sveta Padmanabhan
Theses and Dissertations
Interferon-γ (IFNγ) is a pleiotropic cytokine that has a crucial role in immune response and tumor immunity. Because of its anti-tumor effects, IFNγ has been used in cancer treatment. However, IFNγ also has tumor-promoting functions that are less well understood. Here, I show that IFNγ induces expression of the pro-inflammatory and pro-angiogenic chemokine interleukin-8 (IL-8, CXCL8) in ovarian cancer (OC) cells. The IFNγ-induced IL-8 expression is dependent on JAK1, STAT1, and p65 NFκB, and is associated with an increased occupancy of K314/ 315 acetylated p65 NFκB and Ser-727 phosphorylated STAT1 at the IL-8 promoter. Neutralization of IL-8 using anti-IL-8 antibody …
Functional Modulation Of The Cav3.1 Calcium Channel By Alternative Splicing At The C-Terminus, Ruizhi Wang
Functional Modulation Of The Cav3.1 Calcium Channel By Alternative Splicing At The C-Terminus, Ruizhi Wang
Theses and Dissertations
The CACNA1G gene encodes for Cav3.1, the alpha-1G subunit of a low-voltage-activated T-type calcium channel, which plays crucial roles in cardiac and smooth muscle cells and neurons by influencing the transmembrane potentials and regulating intracellular Ca2+ signaling. Heterozygous missense mutations in the CACNA1G gene cause spinocerebellar ataxia-42 (SCA42), a heterogeneous group of neurodegenerative disorders characterized by brainstem and cerebellum degeneration, and mice that are null for this gene present severe motor coordination defects, abnormal electrical conductance in the heart, aberrant action potentials in the brain, disrupted sleeping patterns, and absence epilepsy. Different splice variants of Cav3.1 have been described, and …
