High Frequency Analysis Of The Carbon Dioxide Linkage Between Terrestrial And Aquatic Ecosystems, Amanda G. Theall May 2025

High Frequency Analysis Of The Carbon Dioxide Linkage Between Terrestrial And Aquatic Ecosystems, Amanda G. Theall

Master's Theses and Capstones

Carbon dioxide (CO2) is a potent greenhouse gas, and surface water concentrations are often supersaturated relative to the atmosphere. To fully quantify CO2 dynamics in stream ecosystems, it is critical to understand sources of stream CO2, particularly the link between terrestrial and aquatic ecosystems. It is unclear how soil CO2 enters streams and to what magnitude. To address this knowledge gap, I analyzed high-frequency CO2 time-series of soil and stream water sensor data to understand source-sink dynamics and time lags between the two pools. I used seven years of hourly sensor data from three soil depths with upscaled 15-minute stream …


Flexibly Changing Resource Allocation In Individuals With Mild Traumatic Brain Injury (Mtbi), Alyssa Walker May 2025

Flexibly Changing Resource Allocation In Individuals With Mild Traumatic Brain Injury (Mtbi), Alyssa Walker

Master's Theses and Capstones

Introduction: The current study examined how individuals with mild traumatic brain injuries (mTBIs) can shift their attentional efforts in real-time. These abilities were examined within a dual-task, during which individuals had to perform two tasks simultaneously. The first research question compared the performance of healthy controls and concussion participants on individual subtasks of the dual-task. The second research question explored how effective healthy controls versus concussion participants were in shifting their attentional resources. The final research question examined the effect of fatigue, specifically whether concussion participants would demonstrate a greater fatigue effect and have more difficulty at the end of …


Per- And Polyfluoroalkyl Substances In A Suburbanizing Watershed, Bailey Mullins May 2025

Per- And Polyfluoroalkyl Substances In A Suburbanizing Watershed, Bailey Mullins

Master's Theses and Capstones

Per- and polyfluoroalkyl substances (PFAS) are persistent man-made chemicals that accumulate in aquatic environments due to their widespread industrial and commercial use and resistance to degradation. Understanding their spatial distribution and relative abundance in streams draining suburbanizing watersheds is crucial for effective watershed and water quality management. This study investigates how the concentrations and composition of PFAS in surface water and sediment are impacted by urbanization. PFAS were quantified in the Lamprey River watershed, a coastal watershed in southeastern New Hampshire that is experiencing ongoing suburbanization. Sampling sites include tributaries, mainstem, and estuarine areas. Surface water, sediment, and well water …


Using Hyperspectral Uas To Map Hydrated Compounds In Martian Terrestrial Analog Systems, Andrew G. Fleming May 2025

Using Hyperspectral Uas To Map Hydrated Compounds In Martian Terrestrial Analog Systems, Andrew G. Fleming

Master's Theses and Capstones

Hypersaline lakes and playas in arid environments on Earth can serve as analogs for paleolake environments of interest on Mars because the hydrated compounds within these systems indicate the presence of ancient hydrologic networks and display strong relationships with microbial life. Traditional orbital observations map these compounds at spatial resolutions ranging from tens to hundreds of meters per pixel. This study uses in-situ measurements, Uncrewed Aerial Systems (UAS) hyperspectral mapping (10 cm), and EnMAP satellite hyperspectral mapping (30 m) to map heterogeneous mineralogical assemblages in hypersaline lakes in Southcentral British Columbia, Canada (BC). We tested the ability of high-resolution UAS …


Linking Nutrient Cycling And Ecological Dynamics: A Case Study Of Internal Phosphorus Loading In The Lake Kanasatka Watershed, Georgia Bunnell May 2025

Linking Nutrient Cycling And Ecological Dynamics: A Case Study Of Internal Phosphorus Loading In The Lake Kanasatka Watershed, Georgia Bunnell

Master's Theses and Capstones

Even with extensive implementation of best management practices to mitigate external nutrient loading, numerous New Hampshire lakes are experiencing diminished water quality due to internal phosphorus loading (IPL). Remobilization of legacy nutrients like phosphorus can lead to more frequent and prolonged cyanobacteria blooms and exacerbate the process of eutrophication. This is the case for Lake Kanasatka, located in Moultonborough, New Hampshire, where IPL contributes to nearly 25% of its total phosphorus budget, with that percentage increasing towards 50% by the end of summer, as the hypolimnion becomes anoxic. After years of monitoring and watershed management, Lake Kanasatka received an aluminum …


Understanding The Epigenetic Role Of Prmt5 Inhibitors In Rna Binding Proteins And Histones Involved In Merkel Cell Carcinoma Tumorigenesis., Devya Gurung May 2025

Understanding The Epigenetic Role Of Prmt5 Inhibitors In Rna Binding Proteins And Histones Involved In Merkel Cell Carcinoma Tumorigenesis., Devya Gurung

Master's Theses and Capstones

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer with a 30% mortality rate. In the United States, 80% of MCC cases are linked to the integration of Merkel cell polyomavirus (MCPyV), while the remaining cases are associated with excessive ultraviolet (UV) exposure, leading to UV-induced DNA damage. The therapeutic targets for MCC remain largely unknown. Elevated expression of Protein Arginine Methyltransferase-5 (PRMT5) has been observed in various cancers. My research aims to investigate how arginine methylation impacts the regulatory mechanisms of RNA-binding proteins and histone residues during neuroendocrine transdifferentiation in MCC. Recent studies suggest that low …


Fine-Scale Movements And Inferred Behavioral States Of Jonah Crabs (Cancer Borealis) In Relation To Size, Sex, And Claw Removal Using An Acoustic Telemetry Positioning System, Maureen Estella Madray May 2025

Fine-Scale Movements And Inferred Behavioral States Of Jonah Crabs (Cancer Borealis) In Relation To Size, Sex, And Claw Removal Using An Acoustic Telemetry Positioning System, Maureen Estella Madray

Master's Theses and Capstones

AbstractJonah crabs (Cancer borealis) are an economically and ecologically valuable fishery species found in the Northwest Atlantic Ocean. As fishing pressure on Jonah crabs in US waters grows, catch-per-unit-effort (CPUE) has declined in recent years. The notable decline in CPUE seen in the US Jonah crab fishery indicates that alternative fishery practices, such as claw-only harvesting, should be further investigated to determine the potential utility in improving the health and sustainability of this evolving fishery. Claw harvesting, one potential relief to fishing mortality, may offer a decrease in crab mortality but is also affected by removal technique as well as …


Marine Oil Snow Settling Rates In Cold Water Environments, Quinn Richard Wilkins May 2025

Marine Oil Snow Settling Rates In Cold Water Environments, Quinn Richard Wilkins

Master's Theses and Capstones

Naturally forming marine snow has long been studied as a primary transport mechanism of organic carbon from the surface of the ocean to the benthic environments. Before the Deep Water Horizon oil spill, marine snow was not considered a significant transport mechanism for oil spilled at the surface. Interactions between sediment and oil have been studied in the past, however the study of Marine Oil Snow (MOS) is an emerging research topic to better understand the fate of spilled oil. A previous UNH graduate student, Jesse Ross, investigated the potential for spilled oil to interact with marine snow via field …


Effects Of Silvicultural Burns On Quercus Rubra Regeneration Near Its Northern Range Limit, Khanh Ton May 2025

Effects Of Silvicultural Burns On Quercus Rubra Regeneration Near Its Northern Range Limit, Khanh Ton

Master's Theses and Capstones

Northern red oak (Quercus rubra) is predicted to expand its range northward in the northeastern United States with climate change and could greatly improve resilience of managed forests by expanding the functional diversity. However, red oak regeneration across its range currently faces many challenges including predation, pathogens, and consequences of forest mesophication such as insufficient light and competition with more mesic species. The latter challenges are potentially caused by the near absence of fire in most northeastern forested landscapes since the early 1900s. Therefore, prescribed burns may help address these challenges and hence promote oak recruitment and establishment. We studied …

Using Rna Sequencing To Investigate Cerebral Gene Expression In Cactus Mice, Sarah Nicholls

Inquiry Journal Spring 2025

As extreme environments like deserts expand due to global climate change, biologists are looking to the weird and wonderful creatures that live within them to instruct conservation efforts. The cactus mouse is one of the most hardcore desert specialists: It has adapted to be able to live its entire life without drinking water, and the MacManes evolutionary genomics lab at UNH, where I’ve worked for the past three years, is dedicated to finding out how. For my Honors senior thesis in biochemistry, supported by a Summer Undergraduate Research Fellowship, I conducted a transcriptomic study to investigate the root instigator of …


Mane Pulling And Stress Response: Investigating The Welfare Impact Of An Equine Husbandry Practice, Rowan Grzeszkiewicz-O’Neill Apr 2025

Mane Pulling And Stress Response: Investigating The Welfare Impact Of An Equine Husbandry Practice, Rowan Grzeszkiewicz-O’Neill

Inquiry Journal Spring 2025

This study assessed stress response in horses during mane pulling, a practice that involves using a metal comb to tear out hairs in order to create an even and thin mane for horse showing. Seven horses from the UNH equine program were tested under three conditions: the experimental condition, during which they had their manes pulled; the baseline condition, in which they were not handled during testing; and the control condition, where the horse’s manes were brushed using a hairbrush. I collected data on heart rate, how frequently horses showed certain behaviors, and the temperature of a structure of the …

Vervet Monkey Orphans Raised Via Surrogacy And How Their Behaviors Differ From Those Of Vervet Monkeys Born And Raised Biologically, Morgan Breen Apr 2025

Vervet Monkey Orphans Raised Via Surrogacy And How Their Behaviors Differ From Those Of Vervet Monkeys Born And Raised Biologically, Morgan Breen

Inquiry Journal Spring 2025

Increasingly higher rates of orphan Vervet Monkeys (Chlorocebus pygerythrus) are ending up in rehabilitation centers all over Africa. This species is viewed as a pest and is often hunted or killed by humans, however, they play a vital role in their ecosystem. They also have extremely complex social hierarchies, living in large matriarchal troops which makes them difficult to rehabilitate. Through the use of surrogate mothers, orphans can learn survival skills and be reared without relying solely on human care. This study aims to assess how to provide these orphaned monkeys with the best chance of survival once released by …


The Short-Term Effects Of Fluctuating Sleep Timing On Cardiovascular And Metabolic Health, Gabe Dennett Apr 2025

The Short-Term Effects Of Fluctuating Sleep Timing On Cardiovascular And Metabolic Health, Gabe Dennett

Inquiry Journal Spring 2025

This study investigates the short-term effects of an acute circadian fluctuation protocol on the cardiovascular and metabolic health of young recreationally active college students. While the deleterious effects of sleep deprivation on a person’s health are wide reaching and well established, circadian misalignment—the discrepancy between biological clocks and external cues—remain under investigated. This research highlights “social jet lag,” a common phenomenon among young people wherein inconsistent sleep and wake times driven by social, school, work, or other commitments creates irregularity in hormonal rhythms, autonomic, and metabolic processes; emphasizing the emerging recognition that not just how much we sleep, but when …
