Compositional Traits In Sorghum Bicolor Characterized By Transcriptome, Ionome And Genome-Wide Association Analysis, Nadia Shakoor
Compositional Traits In Sorghum Bicolor Characterized By Transcriptome, Ionome And Genome-Wide Association Analysis, Nadia Shakoor
Theses and Dissertations
To address the challenge of global mineral malnutrition, current biofortification research in crop plants aims to improve mineral concentration and micronutrient bioavailablity via genetic and traditional breeding methods. Many staple food crops are also used as biofuels, and the chemical and mineral composition of these energy crops directly affect biomass quality and subsequent energy output. Identification of genes and QTL that impact mineral and compositional traits in the grain and biomass of major cereals, including sorghum, is fundamental to developing breeding and selection methods aimed at increasing bioavailable minerals and improving biofuel suitability and seed nutritional quality. A combinatorial strategy …
Marine Population Connectivity: Range Boundaries And Climate Change, Rhiannon Leigh Rognstad
Marine Population Connectivity: Range Boundaries And Climate Change, Rhiannon Leigh Rognstad
Theses and Dissertations
Population connectivity, particularly in open systems, is an important metric for understanding population-level processes on both ecological and evolutionary timescales. In coastal marine systems, adults are typically sedentary and dispersal occurs primarily during a larval stage when individuals are transported in ocean currents. Because coastal marine populations exist as networks of interconnected subpopulations, variation in the magnitude and extent of population connectivity can have profound effects on population dynamics and species distribution limits. Connectivity is a complex process, affected by a multitude of factors, including adult inputs and physical dispersal, which operate at multiple scales and may interact. This dissertation …
Thermal Ecology And Physiology Of An Intertidal Predator-Prey System: Pisaster Ochraceus And Mytilus Californianus, Cristian J. Monaco
Thermal Ecology And Physiology Of An Intertidal Predator-Prey System: Pisaster Ochraceus And Mytilus Californianus, Cristian J. Monaco
Theses and Dissertations
Untangling natural systems’ complexity requires understanding the mechanisms responsible for organisms’ responses to environmental change. Recently, significant advances have been made by recognizing the relevance of direct and indirect effects, which take place when multiple biotic and abiotic factors influence each other. I examined potential direct effects of environmental variables on a predator-prey interaction, as well as potential indirect effects of these variables on the interaction itself. I placed emphasis on behavioral and physiological adaptations, which would potentially contribute/modify these effects. My study system was comprised of a rocky intertidal keystone predator, the sea star Pisaster ochraceus, and its main …
Neodymium Isotopic Signature Of The Deep Western Boundary Current And The Distribution Of Neodymium Isotopes And Concentrations Across Line W, Brian Daniel Duggan
Neodymium Isotopic Signature Of The Deep Western Boundary Current And The Distribution Of Neodymium Isotopes And Concentrations Across Line W, Brian Daniel Duggan
Theses and Dissertations
The capacity of the neodymium (Nd) 143Nd/144Nd ratio to trace modern ocean circulation accurately allows for the assumption that the ratio can also accurately trace paleo ocean circulation. Therefore, a complete understanding of Nd cycling and its effect on the isotopic composition in the oceans is vital. Traditionally, Nd isotopic composition (Nd IC) is considered a conservative property in the open ocean, while coastal and margin environments tend to be dictated by nonconservative exchange processes. However, Nd concentrations ([Nd]) in the open ocean typically display a nutrient like profile, increasing with depth. Such a discrepancy between Nd IC and [Nd] …
Climatic Controls On Organic Matter Decomposition In Boreal Peatlands, Michael J. Philben
Climatic Controls On Organic Matter Decomposition In Boreal Peatlands, Michael J. Philben
Theses and Dissertations
Boreal peatlands currently contain 550 Pg C and are located at high latitudes where mean annual temperatures are expected to increase by as much as 7°C by the end of the century. There is growing concern that warming will stimulate decomposition, transforming peatlands from a sink to a source of atmospheric carbon dioxide and accelerating climate change. A primary goal of this dissertation was to evaluate the effect of climate change on organic matter decomposition in peatlands. This was achieved by developing and employing biochemical tracers to indicate the extent of peat decomposition across a range of naturally occurring climatic …
Molecular Mechanisms Of Gap Junction Regulation By The E3 Ubiquitin Ligase Wwp1, Measho Hagos Abreha
Molecular Mechanisms Of Gap Junction Regulation By The E3 Ubiquitin Ligase Wwp1, Measho Hagos Abreha
Theses and Dissertations
Ubiquitylation is a post-translational modification that influences a wide variety of cellular processes including protein degradation, protein subcellular localization, cell cycle progression, transcription, and DNA damage repair. Covalent attachment of the small ubiquitin molecule to a target protein involves the sequential action of three enzymes (E1, E2, and E3). In this process, substrate specificity is conferred by the E3 ligase. Our work has focused on the function of one such E3 ubiquitin ligase, WWP1. Known targets of WWP1 include cell cycle proteins, tumor suppressors, and transcription factors that promote differentiation of mesenchymal stem cells to the osteoid lineage. Recently, we …
Ferric Reductases And Transporters That Contribute To Mitochondrial Iron Homeostasis, Anshika Jain
Ferric Reductases And Transporters That Contribute To Mitochondrial Iron Homeostasis, Anshika Jain
Theses and Dissertations
Iron (Fe) is the fourth most abundant element in the Earth’s crust, yet the availability of Fe to plants is often limited. This is because in most soil types, Fe precipitates as ferric-oxyhydroxy complexes, making it unavailable for uptake by plants. While the mechanisms involved in Fe uptake from the soil are relatively well understood, the mechanisms involved in its further distribution to the aerial portion of the plant and to subcellular compartments are not fully understood. During Fe deprivation, plants up-regulate root Fe acquisition machinery. How plants sense Fe deprivation and tie the Fe status of the plant to …
Diversity, Genetics, And Health Benefits Of Sorghum Grain, Davina Rhodes
Diversity, Genetics, And Health Benefits Of Sorghum Grain, Davina Rhodes
Theses and Dissertations
Staple cereal crops provide the majority of nutrients to the world's population, and thus, can significantly impact human nutrition and health. Phenotypic and genetic diversity within a crop can be useful for biofortification and crop improvement, but quantitative phenotyping is needed to identify varieties with high or low concentrations of a nutrient of interest, and to identify alleles responsible for quantitative trait variation of the nutrient. Sorghum [Sorghum bicolor (L.) Moench] is a diverse and widely adapted cereal crop that provides food for more than 500 million people in sub-Saharan Africa and Asia, and is becoming increasingly popular in specialty …
The Roles Of Gsk-3ss And Apc In Cytoplasmic Dynein Regulation, Feng Gao
The Roles Of Gsk-3ss And Apc In Cytoplasmic Dynein Regulation, Feng Gao
Theses and Dissertations
Dynein is a microtubule minus-end directed molecular motor, participating in a broad range of cellular functions, such as organelle transport, cell migration and mitosis. Dynein dysfunction is linked to many diseases including ALS, schizophrenia, Alzheimer’s disease, Parkinson’s disease and cancer. The mechanism of dynein regulation is largely unknown. We have provided evidence that glycogen synthase kinase 3β (GSK-3β) directly regulates dynein in both neurons and non-neuronal cells. GSK-3β interacts with and phosphorylates dynein in vitro. Dynein phosphorylation by GSK-3β reduces its interaction with Ndel1, a regulator contributing to dynein force generation. Dynein motility is stimulated both by pharmacological GSK-3β inhibitors …
Global Climate Change And The Southern Ocean: How Antarctic Fishes Physiologically Respond To A Changing Environment From The Cellular To The Organismal Level, Laura A. Enzor
Theses and Dissertations
Studies have projected that future changes in sea surface temperature and pCO2 levels will impact higher latitudes to a greater extent than in temperate regions. For notothenioid fishes of the Southern Ocean, evolution in extremely stable, cold waters has resulted in several adaptations which have left these fishes poorly prepared for global climate change. I have analyzed the metabolic and cellular response of Trematomus bernacchii, Pagothenia borchgrevinki and Trematomus newnesi to a long-term, multi-stressor scenario relevant to the predicted changes in the Southern Ocean. By combining whole animal respirometry with cellular level analysis of energy allocation, osmoregulatory mechanisms and cellular …
Methods For Identifying Regions Of Brain Activation Using Fmri Meta-Data, Meredith A. Ray
Methods For Identifying Regions Of Brain Activation Using Fmri Meta-Data, Meredith A. Ray
Theses and Dissertations
Functional neuroimaging is a relatively young discipline within the neurosciences that has led to significant advances in our understanding of the human brain and progress in neuroscientific research related to public health. Accurately identifying activated regions in the brain showing a strong association with an outcome of interest is crucial in terms of disease prediction and prevention. Functional magnetic resonance imaging (fMRI) is the most widely used method for this type of study as it has the ability to measure and identify the location of changes in tissue perfusion, blood oxygenation, and blood volume. In practice, the three-dimensional brain locations …
The Role Of Lis1 In Adult Mammalian System, Xu Gao
The Role Of Lis1 In Adult Mammalian System, Xu Gao
Theses and Dissertations
Lis1 haploinsufficiency in humans results in a “smooth brain” phenotype called lissencephaly, and also causes severe cognitive and motor impairments and epilepsy. Seizure severity and frequency typically worsens with time; patients often die within the first decade due to seizure-induced aspiration and pneumonia. Various mouse models have been used to examine the role of Lis1 during brain development, and it is clear that Lis1 regulates a microtubule motor, cytoplasmic dynein. Intriguingly, Lis1 expression remains high in adult brains indicating that it plays a role in mature systems. Indeed, our group found that Lis1 and several related proteins regulate dynein-dependent axon …
Understanding The Evolutionary History Of Biochemical Innovation, Madeline Opal St. Julien
Understanding The Evolutionary History Of Biochemical Innovation, Madeline Opal St. Julien
Theses and Dissertations
The serine protease (SP) gene family is an ecologically important gene family because of observed involvement in innate immunity, digestive processes, and embryological development of arthropods. In the past decade, all genes of the serine protease family have been classified in a number of arthropods, with the exception of crustacean. Possible evolutionary mechanisms have been observed based off of varying selectional pressures acting on recent SP expansions in respect to varying diets. Daphnia is the first crustacean to have its genome sequenced, and their genomes were analyzed in this study to elucidate the expansion and divergence of the SP gene …
An Investigation Of Mitochondrial Bioenergetics And The Turnover Of Succinated Proteins In The Adipocyte During Diabetes, Ross Tanis
Theses and Dissertations
We previously identified the chemical modification S-(2-succino)cysteine (2SC), which is formed when the Krebs cycle metabolite fumarate reacts with protein cysteine residues, also termed protein succination. Protein succination is increased in the adipose tissue of ob/ob and db/db mice in vivo and in 3T3-L1 adipocytes grown in high glucose in vitro. The increase in 2SC in the 3T3-L1 adipocyte occurs as a direct result of glucotoxicity and increased mitochondrial stress. We have shown that uncoupling agents, which lower mitochondrial stress, prevent the increase in succinated proteins.
In this study we examined the relationship between increased succination and mitochondrial bioenergetics in …
The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky
The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky
Theses and Dissertations
Cognitive reserve theory suggests that physical activity may protect individuals from cognitive decline. At the brain level, greater cognitive reserve may manifest as greater neural network efficiency. Our purpose was to investigate 1) whether participation in a 16-week walking program increased brain efficiency, and 2) whether increased brain efficiency correlated with change in fitness and task performance. Our secondary purpose was to investigate whether exercise training improved performance on a battery of cognitive tasks, particularly executive functioning performance. Seventeen healthy but sedentary women aged 60-75 years participated in a supervised walking program; eighteen women served as a non-randomized control group. …
Differential Expression Of Snmps And Their Underlying Transcriptional Regulation In Chemosensory Pathways Of Drosophila, Richard A. Fandino
Differential Expression Of Snmps And Their Underlying Transcriptional Regulation In Chemosensory Pathways Of Drosophila, Richard A. Fandino
Theses and Dissertations
Insects possess complex and diverse chemosensory pathways which have specific phenotypes determined by the regulated expression of specific combinations of genes. While many of these genes (e.g. ORs and GRs) have very narrow expression patterns, associating with only a limited number of chemosensory sensilla, SNMPs show a very broad expression pattern. In Drosophila, SNMP1 and SNMP2 associate with the majority of olfactory and gustatory sensilla, but express in different cell types. In olfactory sensilla, SNMP1 and SNMP2 associate with trichoid or coeloconic neurons respectively, and both additionally express in a variety of sensilla support cells; in gustatory sensilla, SNMP2 expresses …
Functional Characterization Of Fro4 And Fro5: Two Members Of The Ferric Chelate Reductase Family Of Arabidopsis, Grandon Thomas Wilson
Functional Characterization Of Fro4 And Fro5: Two Members Of The Ferric Chelate Reductase Family Of Arabidopsis, Grandon Thomas Wilson
Theses and Dissertations
Iron (Fe) is the fourth most abundant element within the earth’s crust and is an essential micronutrient for plants and animals. Fe plays key roles in photosynthesis, respiration and chlorophyll biosynthesis in plants and in hemoglobin in animals. Like Fe, copper (Cu) is also an important micronutrient in plants and is needed for photosynthesis and respiration, especially in the important copper-containing protein plastocyanin. Copper also is important in scavenging reactive oxygen species and ethylene perception. The reduction of Fe3+ to Fe2+ at the root surface of Arabidopsis thaliana during times of Fe deficiency has been a well-characterized process; however, reduction …
Utilizing Next Generation Sequencing To Generate Bacterial Genomic Sequences For Evolutionary Analysis, Derrick C. Scott
Utilizing Next Generation Sequencing To Generate Bacterial Genomic Sequences For Evolutionary Analysis, Derrick C. Scott
Theses and Dissertations
Many important questions in the field of prokaryotic biology cannot be answered due to the low availability of sequenced and finished genomes. Recent improvements in technology and decreases in price have made the ambition of de novo bacterial genomic sequencing a reality for a wide range of researchers. However, with the advancement of sequencing technology comes the need for an evaluation to determine the most reliable bioinformatics methods in generating a complete and accurate assembly. Biases inherent in the sequencing technology and GC-rich genomes complicate genome assemblies. Here, we sequenced bacterial strains from the GC-rich Caulobacter genus and the closely …
Muscarinic Modulation Of Basolateral Amygdala, Lei Liu
Muscarinic Modulation Of Basolateral Amygdala, Lei Liu
Theses and Dissertations
The basolateral amygdala (BL) receives a dense cholinergic innervation from the basal forebrain. Despite the importance of muscarinic acetylcholine receptors (mAChRs) in fear learning, consolidation, and extinction, there have been no studies that have systematically investigated the functional role of mAChRs in regulating emotional processing in the BL. To address this critical knowledge gap we combined brain slice whole-cell recording, optogenetics, and immunohistochemistry to determine how muscarine, acting on mAChRs, regulates neuronal oscillations, synaptic transmission and plasticity in the BL.
Neurons in the BL oscillate rhythmically during emotional processing, which are thought to be important to integrate sensory inputs, allow …
Mechanical Properties Of Diet And Its Effect On Oral Health, Varsha Kapoor
Mechanical Properties Of Diet And Its Effect On Oral Health, Varsha Kapoor
Theses and Dissertations
The predominant diet fed to captive carnivores consists of ground meat formulated to provide full nutritional requirements. However, this ground meat diet completely lacks the mechanical properties such as toughness, hardness and stiffness of the foods the animals would eat in the wild. The goal of this research was to evaluate the effect of mechanical properties of diet on oral health by comparing prevalence of periodontal disease and calculus accumulation in wild and captive felids. One-way ANOVA analysis of variance indicated that these differences are statistically significant (P
The Effects Of Arthritis Foundation’S “Walk With Ease” Program On Cognitive Function, Ryan S. Falck
The Effects Of Arthritis Foundation’S “Walk With Ease” Program On Cognitive Function, Ryan S. Falck
Theses and Dissertations
Physical activity (PA) is believed to improve cognitive function, particularly executive function, in older adults. However, few interventions in community settings have been performed to improve executive function through PA. The purpose of this study was to determine the effects of a community-based walking program on executive function in older adults (60+ years). Older adults from senior centers throughout Lexington County, SC were recruited for participation in this intervention. Exclusion criteria included currently exercising >30 minutes and exercising ≥2x/week or scoring ≤25 on the Mini-Mental State Exam. The intervention consisted of an evidenced-based community walking program, the Arthritis Foundation ’ …
Geochemical Analysis Of Eolian Fluxes During The Transition From Greenhouse To Icehouse Conditions In Equatorial Pacific., Daniel Nicholas Miller
Geochemical Analysis Of Eolian Fluxes During The Transition From Greenhouse To Icehouse Conditions In Equatorial Pacific., Daniel Nicholas Miller
Theses and Dissertations
To assess the atmospheric conditions during times of differing pole to equator thermal gradients through the middle Eocene to early Oligocene, 42 to 30 Ma, samples from deep-sea sediment cores U1331, U1332, U1333 from IODP Expedition 320/321 in the eastern equatorial Pacific (EEP) have been chemically leached to isolate the operationally defined eolian dust (ODED; <63 μm fraction). The ODED was analyzed for neodymium (Nd) isotopic compositions and rare earth element (REE) concentrations in order to determine the provenance of the ODED fraction and to elucidate the environmental conditions (e.g. predominant wind patterns) during deposition over the interval of study. The variations in the ODED fraction are expected to be controlled by changes in sources delivered via eolian input. However, negative cerium anomalies in the Post Achaean Australian Shale (PAAS) normalized rare earth element profiles of the ODED show a biasing geochemical seawater phase to the ODED signature. It is found that εNd values and cerium anomalies (Ce/Ce*) of ODED are consistent with fossil fish teeth values that record bottom water signatures from the same location and time period until ~36-37 Ma; around the Priabonian/Bartonian boundary marked by increased thermal gradients due to the emplacement of high elevation glaciers on Antarctica (Scher et. al., 2014). Moreover, the more negative cerium anomalies correlate to more radiogenic εNd values. The geochemical seawater signature in the ODED samples is believed to be caused by a change in sedimentary phase regulated by the spatial paleoposition of the sites relative to the biological high productivity zone and/or the depth of the CCD. Subsequently these regulators on the sedimentary phases of the ODED were investigated for biasing the geochemical signatures of the ODED, assumed to be changes in sources thereby provenance. Together, the Nd and REE results from the study temporally indicate that the ODED fraction may be a mixing between two sources, that of a biasing biogenic and/or authigenic source that records seawater conditions, and that of an older, less radiogenic continental source, inferred as Asian loess, as an increased thermal gradient prevails over the course of the study. Further research needs to be performed to make more robust and conclusive linkages between sources, mixing of sources, and atmospheric eolian delivery patterns, highlighting the necessity for a better understanding of atmospheric conditions during important climatic events throughout the history of the Earth.
Genetic Background Influences Behavior And Responses To Epigenetic Changes Induced By A Methyl-Donor Diet, Kimberly R. Shorter
Genetic Background Influences Behavior And Responses To Epigenetic Changes Induced By A Methyl-Donor Diet, Kimberly R. Shorter
Theses and Dissertations
With recent strides in epigenetics, mainstream media informs the public that we can “beat our genes” by, for instance, changing our diet. Genetics, however, still plays a role in phenotype. Folate and other methyl-donor pathway components are widely supplemented due to their ability to prevent neural tube defects during prenatal development. In addition to vitamins, these compounds are also added to commercial flour, energy drinks, and other supplements. Several lines of evidence suggest that these supplements act through epigenetic mechanisms, including altering DNA methylation. Increasing evidence suggests potential deleterious effects of excessive folate. Given the benefits of these compounds, risk …
Effects Of Individual Phenotypic Variation On Predator-Prey Relationships Of Xanthid Crabs In North Inlet Estuary, South Carolina, Benjamin J. Toscano
Effects Of Individual Phenotypic Variation On Predator-Prey Relationships Of Xanthid Crabs In North Inlet Estuary, South Carolina, Benjamin J. Toscano
Theses and Dissertations
Ecological communities and the biological interactions that regulate community structure are notoriously complex. To make these systems more tractable, ecologists traditionally measure and model communities at the population level, treating individuals as functionally equivalent. While this approach has yielded tremendous insight into the factors governing communities, it remains unclear whether accounting for individual-level variation could improve our capacity to predict the responses of communities to perturbation, a major goal in the midst of unprecedented rates of environmental change.
The objective of this study was to examine the magnitude of individual-level phenotypic variation in predatory crabs (family Xanthidae), and the effects …
Role Of Apelin And Endothelin Systems In The Pain Associated With Sickle Cell Disease, Terika Smith
Role Of Apelin And Endothelin Systems In The Pain Associated With Sickle Cell Disease, Terika Smith
Theses and Dissertations
Sickle cell disease (SCD) is a common genetic blood disorders that is characterized by painful vaso-occlusive episodes (VOEs), which are the major cause of hospitalizations for these patients. One of the mechanisms that may contribute to the development of painful VOEs is the imbalance between vasoconstrictors and vasodilators. This thesis focuses on the vasoconstrictors endothelin-1 (ET-1), which is elevated during VOEs and is pro-nociceptive, and angiotensin II (Ang II) and the vasodilator apelin, which has anti-nociceptive properties. This thesis tested two hypotheses: 1) an imbalance between the vasoconstrictive and pro-nociceptive systems and vasodilatory and anti-nociceptive systems contributes to pain in …

My senior thesis project was to become a certified Les Mills BODYPUMP instructor. In order to obtain my certification I had to go through training, which was paid for by the University of South Carolina. Training was a mentally and physically demanding weekend full of lifting weights and learning everything there is to know about BODYPUMP techniques, choreography, and coaching. Afterwards, I had sixty days to send in a video of myself teaching the class to a group of participants in order for my teaching skills to be evaluated by Les Mills. I passed my evaluation and am now a …
Role Model Fathers Or Deadbeat Dads? A Study Of Peromyscus Paternal Behavior, Taylor Wapshott
Role Model Fathers Or Deadbeat Dads? A Study Of Peromyscus Paternal Behavior, Taylor Wapshott
Senior Theses
Paternal behavior is a largely understudied and poorly understood topic, especially in mammalian species. Many current mammalian models for paternal behavior use a comparative approach, taking advantage of natural differences in behavior between closely related species. This study compared paternal behavior in two rodent species, namely Peromyscus maniculatus (BW) and Peromyscus polionotus (PO). PO rodents have been shown to be monogamous, but there have been no studies of their paternal behavior at this time. 10 PO males and 12 BW males were filmed in their home cage for a 10 minute period following initial disturbance of their nest and removal …
Genome Sequence And Phenotypic Characterization Of Caulobacter Segnis, Sagar Patel
Genome Sequence And Phenotypic Characterization Of Caulobacter Segnis, Sagar Patel
Senior Theses
Caulobacter segnis is a unique species of Caulobacter in that it is slow growing, found in soil samples, and has other phenotypic differences from the freshwater Caulobacter that it is most closely related to. Initially deemed Mycoplana segnis, it was reclassified after a 16s rRNA analysis and found to be most closely related to the Caulobacter NA1000 branch. Because the annotated sequence available in GenBank contained a large number of pseudogenes (126), we compared the original sequencing data to the GenBank sequence and determined that many of the pseudogenes were due to sequence errors in the Genbank sequence. Consequently, …
A Comparison Of Angiography Versus Intravascular Ultrasound In The Treatment Of Peripheral Arterial Disease, Michael Pompliano
A Comparison Of Angiography Versus Intravascular Ultrasound In The Treatment Of Peripheral Arterial Disease, Michael Pompliano
Senior Theses
Peripheral Arterial Disease is a growing epidemic throughout the United States. It is estimated that 8 to 12 million Americans currently suffer from PAD, a disease of the circulatory system that limits blood flow to your hands and feet. This limited blood flow is due to the narrowing of the arteries that supply blood throughout your body and can disrupt the balance of the nerves and tissues that make up your extremities. If left untreated, it can cause irreparable, life- threatening damage that may result in amputation of the diseased limb. Although the mechanism of PAD is known and well …
Determining A Correlation Between Individual Differences In Eye Movements And Working Memory, Mackenzie Sunday
Determining A Correlation Between Individual Differences In Eye Movements And Working Memory, Mackenzie Sunday
Senior Theses
This study determined if a relationship exists between individual differences in eye movements and working memory measures. The eye movement system can provide insight into processes that occur in the mind as well as a better understanding of the relationship between quantifiable aspects of eye movements and the more abstract inner workings of the mind. Recently, consistent and reliable individual differences have been found in individuals’ eye movement behaviors. For example, individuals with longer fixation durations for one visual task have longer fixations across all other visual tasks. The eye movements of participants were collected during four different viewing tasks …
