The MDVs are located in Victoria Land, East Antarctica and have been studied since 1993 as part of the McMurdo Long Term Ecological Research Project. Viruses in the MDVs were shown to be seasonally abundant and …
A Model Of Time-Dependent Macromolecular And Elemental Composition Of Phytoplankton, Anne Willem Omta
A Model Of Time-Dependent Macromolecular And Elemental Composition Of Phytoplankton, Anne Willem Omta
Faculty Scholarship
Phytoplankton Chl:C:N:P ratios are important from both an ecological and a biogeochemical perspective. We show that these elemental ratios can be represented by a phytoplankton physiological model of low complexity that includes major cellular macromolecular pools. In particular, our model resolves time-dependent intracellular pools of chlorophyll, proteins, nucleic acids, carbohydrates/lipids, and N and P storage. Batch culture data for two diatom and two prasinophyte species are used to constrain parameters that represent specific allocation traits and strategies. A key novelty is the simultaneous estimation of physiological parameters for two phytoplankton groups of such different sizes. The number of free parameters …
Salt Pollution Reduces Turbidity, Dissolved Organic Matter, And Cyanobacteria In Experimental Vernal Pool Communities, Jared P. Vigil, Matthew S. Schuler
Salt Pollution Reduces Turbidity, Dissolved Organic Matter, And Cyanobacteria In Experimental Vernal Pool Communities, Jared P. Vigil, Matthew S. Schuler
Department of Biology Faculty Scholarship and Creative Works
Anthropogenic activities such as the over-application of road deicers are causing an increase in the concentration of salts in historically fresh waters. Experimental and field investigations demonstrate that freshwater salinization disrupts ecosystem functions and services, causing the death of freshwater organisms and changes to nutrient conditions. Wetland habitats are one system negatively affected by salt pollution, including ephemeral wetlands (vernal pools) that fill with salt-polluted water after snowmelt. In urbanized areas, the degradation of these ecosystems could result in irreversible ecological damage including reduced water quality and a reduction in biodiversity. To investigate the effects of freshwater salinization on vernal …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Environmental variation commonly drives functional trait diversity within species, among species, and across communities. Climate and shared evolutionary history can both influence trait–environment relationships. We studied variation in plant functional traits among closely related Costus species occurring across environmental gradients, the extent to which this variation occurs within single species, and how that variation may be influenced by shared evolutionary history. We measured leaf, aboveground stem, rhizome, and fine root traits of 17 species of Costus in eight sites in Costa Rica and Panama, which varied in elevation, temperature, and precipitation. We then assessed the relationships among traits and environmental …

Metals and metalloids (hereafter, metal(loid)s) in plant-based foods are a source of exposure to humans, but not all metal(loid)-food interactions are the same. Differences exist between metal(loid)s in terms of their behavior in soils and in how they are taken up by plants and stored in the edible plant tissue/food. Thus, there cannot be one consistent solution to reducing toxic metal(loid)s exposure to humans from foods. In addition, how metal(loid)s are absorbed, distributed, metabolized, and excreted by the human body differs based on both the metal(loid), other elements and nutrients in the food, and the nutritional status of the human. …
Prochlorococcus Death By A Ubiquitous Zooplankton Filter Feeder, Avery Harman
Prochlorococcus Death By A Ubiquitous Zooplankton Filter Feeder, Avery Harman
University Honors Theses
Prochlorococcus is a globally abundant cyanobacterium that can help reveal the ecology of microorganisms in the ocean. Specifically, mortality by zooplankton such as appendicularians is globally important and Prochlorococcus can help reveal some of the choices made around feeding for this ubiquitous filter feeder. Two ecotypes of Prochlorococcus were introduced to appendicularians to determine if appendicularian feed selectively between these ecotypes. Further, a single ecotype of Prochlorococcus was fed to appendicularians over a variety of life stages to determine if retention rate changed with appendicularian life stage. My results reveal that there is no significant selection between the two Prochlorococcus …

Removal As A Control Method For Trachemys Scripta Elegans And The Response Of Chrysemys Picta Bellii, Jacob Swanson
University Honors Theses
The red-eared slider is considered one of the most ubiquitous freshwater turtles globally. Several key ecological advantages and life history traits of this species jointly impact growth rates and survivorship of native freshwater turtles where sympatry occurs. Evaluation of current management actions for red-eared slider turtles is limited, resulting in a paucity of information to guide management for the species and conservation of declining native freshwater turtles. We used previously collected mark-recapture and removal sampling data from sites with sympatric populations of red-eared slider and western painted turtles. We examined the effects of control (trapping and removal) of red-eared sliders …
Mixed Uncertainty Analysis On Pumping By Peristaltic Hearts Using Dempster-Shafer Theory, Yanyan He, Nicholas A. Battista, Lindsay D. Waldrop
Mixed Uncertainty Analysis On Pumping By Peristaltic Hearts Using Dempster-Shafer Theory, Yanyan He, Nicholas A. Battista, Lindsay D. Waldrop
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
In this paper, we introduce the numerical strategy for mixed uncertainty propagation based on probability and Dempster–Shafer theories, and apply it to the computational model of peristalsis in a heart-pumping system. Specifically, the stochastic uncertainty in the system is represented with random variables while epistemic uncertainty is represented using non-probabilistic uncertain variables with belief functions. The mixed uncertainty is propagated through the system, resulting in the uncertainty in the chosen quantities of interest (QoI, such as flow volume, cost of transport and work). With the introduced numerical method, the uncertainty in the statistics of QoIs will be represented using belief …
Neuroinflammation In Alzheimer’S Disease Mouse Brain Following Repetitive Mild Traumatic Brain Injury, Lujain Almuhanna
Neuroinflammation In Alzheimer’S Disease Mouse Brain Following Repetitive Mild Traumatic Brain Injury, Lujain Almuhanna
Electronic Theses and Dissertations
Traumatic brain injuries (TBIs) are a common form of head injury, with mild TBIs (mTBIs) making up 75-90% of the TBI severity scale. It’s been suggested that repetitive mild TBIs (rmTBIs) may enhance effects of Alzheimer’s Disease (AD). With dementia linking TBI and AD together, we investigated the memory hub of the brain - the hippocampus. Astrocytes and microglia are two glial cells that respond to neuroinflammation and therefore imaged in hippocampal regions of the 3xTg-AD mouse brain. We hypothesized that AD brain pathology (i.e., neuroinflammation) would be accelerated in 3xTg-AD mice following rmTBIs early in life. Analyses revealed that …

Mutating Lysine 336 In Msh6 Does Not Appear To Affect Dna Mismatch Repair In Saccharomyces Cerevisiae, Anthony Thompson, Daniel Reese, Noa Bennafield, Kalila Daveron, Christopher Bolden, Joanna E. Haye-Bertolozzi
XULAneXUS
Defects in the DNA mismatch repair process results in the accumulation of mutations and disease. Mutations in MSH6 and MSH2, encoding for the subunits of the MutSα complex, are often responsible for Constitutional Mismatch Repair Deficiency (CMMRD) and Lynch Syndrome (LS), respectively. This work focused on DNA mismatch repair through analysis of the MSH6 missense variant msh6-K336T. The mutation examined in this study is msh6-K336T in Saccharomyces cerevisiae, which is equivalent to msh6-K431T in humans. The mutation results in the replacement of lysine with threonine, an amino acid with different properties. It was therefore hypothesized that the mutation …

An Investigation Of Cyanobacteria, Cyanotoxins And Environmental Variables In Selected Drinking Water Treatment Plants In New Jersey, Tsung Ta David Hsu, Yaritza Acosta Caraballo, Meiyin Wu
Department of Biology Faculty Scholarship and Creative Works
Harmful Algal Blooms (HAB) have the potential to impact human health primarily through their possible cyanotoxins production. While conventional water treatments can result in the removal of unlysed cyanobacterial cells and low levels of cyanotoxins, during severe HAB events, cyanotoxins can break through and can be present in the treated water due to a lack of adequate toxin treatment. The objectives of this study were to assess the HAB conditions in drinking water sources in New Jersey and investigate relationships between environmental variables and cyanobacterial communities in these drinking water sources. Source water samples were collected monthly from May to …
Investigating The Regulation Of The Hypothalamic-Pituitary-Interrenal Axis In Atlantic Sturgeon (Acipenser Oxyrinchus) Following An Acute Stressor, Liam Doherty
Undergraduate Theses, Capstones, and Recitals
This study investigated the response to acute stress in Atlantic sturgeon (Acipenser oxyrinchus) and HPI axis regulation of glucocorticoid production during stress by examining the expression of key genes― corticotropin-releasing hormone (crh), corticotropin-releasing hormone receptor (crhr), proopiomelanocortin (pomca/pomcb), melanocortin 2 receptor (mc2r), and steroidogenic acute regulatory protein (star)―that are associated with hypothalamus/pituitary/interrenal (HPI) axis of bony fishes. Additionally, tyrosine hydrogenase (th1 and th2) and phosphoenolpyruvate carboxykinase (pepck), found in catecholamine-producing cells in the head kidney of the sturgeon, were investigated …

Assessment Of Georgia’S Royal Catchfly (Silene Regia) Along A Forest-Edge Gradient In A Remnant Prairie Community, Megan Brooks
Master's Theses
Royal catchfly (Silene regia) is a perennial prairie forb known to grow in rocky, alkaline soils within tallgrass prairies of the eastern United States. S. regia is recorded from twelve states, including Georgia, and is now confined to fragmented habitats due to the loss of 95% of its natural environment. The species is now listed as critically imperiled in the state of Georgia. Attempts at reintroduction via outplanting have only shown limited success, necessitating more research on the environmental conditions in which this plant survives in its southern-most distribution. This study investigated the local ecological factors influencing the …

Synanthropic bats live in close proximity to humans and domestic animals, creating opportunities for potential pathogen spillover. We explored environmental correlates of occurrence for a widely distributed synanthropic African bat, Mops pumilus—a species associated with potential zoonotic viruses—and estimated current and future environmental suitability in the Taita Hills region and surrounding plains in Taita–Taveta County in southeast Kenya. To project future environmental suitability, we used four Coupled Model Intercomparison Project Phase 6 general circulation models that capture temperature and precipitation changes for East Africa. The models were parameterized with empirical capture data of M. pumilus collected …

Heterogeneous Resources In Infrastructures Of The Edge Network Paradigm: A Comprehensive Review, Qusay S. Alsaffar, Leila Ben Ayed
Karbala International Journal of Modern Science
The late 1990s saw the rise of the edge computing network paradigm, as well as an increase in the number of IoT de-vices. This concept is viewed as a link between cloud servers and end-devices, bringing processing and storage re-sources closer to clients. As a result of its low latency and high performance, researchers and developers have expressed interest in it. However, this paradigm confronts a number of obstacles and restrictions, including restricted and hetero-geneous resources at network edges. In this paper, we provide a detailed review of heterogeneous resources in edge network infrastructures using a three-dimensional method. These three …
Neuroinflammation And Gut Barrier Function Post Traumatic Brain Injury, Anne Sullivan
Neuroinflammation And Gut Barrier Function Post Traumatic Brain Injury, Anne Sullivan

Determining space use for species is fundamental to understanding their ecology, and tracking animals can reveal insights into their spatial ecology on home ranges and territories. Recent technological advances have led to GPS-tracking devices light enough for birds as small as ~30 g, creating novel opportunities to remotely monitor fine-scale movements and space use for these smaller species. We tested whether miniaturized GPS tags can allow us to understand space use of migratory birds away from their capture sites and sought to understand both pre-breeding space use as well as territory and habitat use on the breeding grounds. We used …
The Aquatic Microbial Environment Shapes The Gut Microbiota, Brain, And Behavior Of Larval Amphibians, Kyle Emerson
The Aquatic Microbial Environment Shapes The Gut Microbiota, Brain, And Behavior Of Larval Amphibians, Kyle Emerson
Electronic Theses and Dissertations
Microbial communities comprising bacteria, viruses, fungi, and protists live within and on the surfaces of animal hosts. These microbial communities exist in symbiosis with the host, and heavily influence host physiology, development, health, and fitness. Gut-dwelling microbes (i.e., gut microbiota) contribute to host neurodevelopment through a bidirectional Microbiota-Gut-Brain (MGB) axis. Evidence of the MGB axis has been primarily derived from studies that use germ-free (GF) models, which commonly display altered neurophysiology and behavior compared to conventionally raised counterparts. Almost all studies of the MGB axis have used mammalian models in a biomedical framework, leaving a knowledge gap regarding the role …

Slime Molds (Myxomycetes) Causing A “Disease” In Crop Plants And Cultivated Mushrooms, Zhaojuan Zhang, Chao Zhi, Yu Li, Steven L. Stephenson, Pu Liu
Biological Sciences Faculty Publications and Presentations
Myxomycetes (plasmodial slime molds) are eukaryotic protist predators that are associated with wood, leaf litter, and soil in forests, where they feed on bacteria, protozoans, and (to a more limited extent) fungi. The health of crop plants is essential because they represent a primary food source for humans. However, when myxomycetes produce numerous fruiting bodies on the stems and leaves of crop plants, which is herein referred to as a myxomycete colonization, this has the potential of interfering with plant photosynthesis, transpiration and respiration by blocking out light and covering stomata. Myxomycetes are not pathogens, but their occurrence on plants …

In the world of microorganisms, cyanobacteria are a uniquely skilled powerhouse. They participate in global nutrient and carbon cycling. They can photosynthesize, which allows them to use sunlight and carbon dioxide to produce cellular energy. However, photosynthesis involves a lot of molecular interactions where environmental stresses can interfere, increasing the chances of oxidative stress and nutrient imbalances that can amplify deleterious effects. One such stress, iron limitation, is well-studied and its responses in the cell are known. This study assesses the differences between responses when induced by two different iron limitation methods. Then, a specific stress response regulator DspA, also …

Paleontological observations of ancient flora and fauna provide powerful insights into past diversity and relationship dynamics between organisms and their environments. Diatoms are globally distributed protists that influence major biogeochemical cycles and sustain oceanic food webs. The fossil diatom record extends 120 million years back to the Early Cretaceous where rare deposits were discovered worldwide and are occasionally represented by diverse communities. However scarce, the taxonomic richness and geographical spread of these diatom communities suggest prior evolutionary events and therefore earlier deposits. To complement the existing fossil information and to discover diatom deposits predating 120 Ma, we examined 33 study …
