Three Fundamental Challenges To The Advancement Of Stemflow Research And Its Integration Into Natural Science, John T. Van Stan Ii, Juan Pinos

Biological, Geological, and Environmental Faculty Publications

Plant canopies divert a portion of precipitation to the base of their stems through "stemflow", a phenomenon that influences the canopy water balance, soil microbial ecology, and intrasystem nutrient cycling. However, a comprehensive integration of stemflow into theoretical and numerical models in natural science remains limited. This perspective examines three unresolved, fundamental questions hindering this integration, spanning the canopy to the soil. First, the precise source area within the canopy that generates stemflow is undefined. Thus, we asked, "whence stemflow?" Current common assumptions equate it to the entire tree canopy, a potentially misleading simplification that could affect our interpretation of …

Comparison Of Energy Budget Of Cockroach Nymph (Hemimetabolous) And Hornworm (Holometabolous) Under Food Restriction, Charles J. Green, Chen Hou

Biological Sciences Faculty Research & Creative Works

Animals with different life histories budget their intake energy differently when food availability is low. It has been shown previously that hornworm (larva of Manduca sexta), a holometabolous insect species with a short development stage, prioritizes growth at the price of metabolism under food restriction, but it is unclear how hemimetabolous insect species with a relatively long development period budget their intake energy under food scarcity. Here, we use orange head cockroaches (Eublaberus posticus) to investigate this question. We found that for both species under food restriction, rates of metabolism and growth were suppressed, but the degree of reduction was …

Whole Genome Sequencing For The Millipede Cherokia Georgiana, Elena Cruz, Will Wittstock, Daniel Hastings, Arnab Sengupta, Bruce A. Snyder

Graduate Research Showcase

Out of thousands of known millipede species, only five sequenced genomes of species (in four of sixteen orders) are publicly available. No whole genomes and limited genetic information are available for incredibly diverse families such as Xystodesmidae. Our research goal is to sequence the whole genome of the millipede Cherokia georgiana. A de novo sequence of the complete genome of a North American species will facilitate future research in understanding gene expression under a variety of conditions. Many interesting biological processes in millipedes are poorly described, such as the production of a defensive hydrogen cyanide secretion found in the …

Checklist And Key To The Millipede Species Of Georgia, United States, With Notes On Distribution, Lance Andrew, Bruce Snyder

Graduate Research Showcase

Millipedes are an exceptionally diverse class of animals that have an impact on soil structure and nutrient cycling. Despite their abundance, importance, and wide distribution, they are understudied compared to other animal taxa, and biogeographical information is scant. Georgia, though the largest state by land area east of the Mississippi River, has largely been overlooked by regional millipede checklists. Without baseline species distributions and abundances to inform wildlife management decisions, sufficient measures cannot be taken to preserve millipede biodiversity, especially in light of recent changes in climate and land use. Taxonomic resources for millipede identification in North America are also …

Do Nest Box Temperatures Affect Nest Success And Nestlings Growth For Eastern Bluebirds?, Mathew Gordon, Katie Stumpf

Graduate Research Showcase

Rising global temperatures due to climate change have caused declines in many species. For birds, temperature is a primary factor in nest site selection and nest success, so successful management will require temperature mitigation techniques. Secondary cavity nesting birds such as the Eastern Bluebird are particularly vulnerable as common occupants of nest boxes, which are often warmer inside than the outside ambient temperature. Temperatures exceeding 42°C can have numerous negative consequences for Bluebirds, including reducing hatching success and nestling growth. We monitored 50 Eastern Bluebird nest boxes (25 are painted white and 25 are unpainted) at Panola Mountain State Park …

Factors That Influence Small Mammal Long Bone Morphology: An Analysis Of The Femora, Tibiae, And Humeri Of The Eastern Gray Squirrel (Sciurus Carolinensis), Tyler Everette Blake

Theses, Dissertations and Capstones

The goal of this study is to examine the effect of urbanization and latitude on bone morphology, specifically limb length and bone density among gray squirrels endemic to the eastern United States. This study’s hypotheses are as follows: gray squirrels occupying lower latitudes will have larger body sizes and longer limbs relative to body size than those at higher latitudes following Bergmann’s and Allen’s rules. Further, squirrels in urban habitats will have greater bone density than those in rural habitats. Results show moderate correlation between body mass and respective proxies and latitude following Bergmann’s rule. Weak correlations were found between …

The Comparison Of Different Wetland Fish Assemblages Over Time, Robert Edward Adelstein

Theses, Dissertations and Capstones

Wetlands provide essential ecosystem services. Historically, we have drained and filled 73% of wetlands for agricultural use throughout the United States from the 1780s to the 1980s (Dahl, 1990). A nationwide focus on restoring wetlands has since occurred. Literature on restored/mitigated wetlands is rife with examples that do and do not support the same ecosystem services as natural wetlands (Langston, 1997; Meil, 2014). Restoration of wetlands occurred at the Green Bottom Wildlife Management Area (GBWMA) over several decades. Various sections of the wetland were classified by age, water depth, and vegetation. One hypothesis was that differences in fish assemblage would …

It employs three methodologies: transparency, accountability, and science-based …

Using Single Cell Genomics To Explore The Impact Of Marine Viruses On Microbial Respiration., Paxton Tomko

MCB Articles

Viral metabolic reprograming of marine prokaryotes, through the use of virally encoded auxiliary metabolic genes (AMGs), plays a critical role in marine ecosystem function by influencing biochemical cycles and genetic diversity in these environments. Despite the fundamental role viruses play in global environmental ecosystems, they remain an understudied aspect of microbial ecology and evolution, in part due to the methods available for studying virus host interactions in natural systems. Thus far, metagenomic analyses have been used to study the interactions of virus host pairs, but these types of analyses have their limitations in accurately linking viruses to hosts, or culture-based …

Can Functional Traits Predict Turnover Of Alpine Plant Species In Yosemite National Park?, Brooke L. Wallasch

Biological Sciences

Alpine species are a useful tool for predicting the effects of climate change on lowland species. A growing body of research has begun assessing the question of how alpine species will change in response to changing climate. In the study of alpine plant species, some researchers have begun exploring the idea that functional traits could be predictive of turnover in alpine plant communities. In this study, I used a species’-level approach to assess the ability of six functional traits (vegetative height, generative height, leaf thickness, leaf area, leaf dry weight, specific leaf area) to predict species turnover in alpine plants …

Fisheries Research Report No. 346: West Coast Demersal Scalefish Resource Synopsis 2024, Emily A. Fisher, David Fairclough

Fisheries Research Reports

The West Coast Demersal Scalefish Resource (WCDSR) comprises over 100 species that inhabit inshore (20-250 m deep) and offshore ( > 250 m deep) waters of the West Coast Bioregion (WCB; north of Kalbarri to east of Augusta).

The WCB is predominantly a temperate oceanic zone with these waters influenced by the Leeuwin Current that transports warm, low-nutrient water southward along the western edge of the continental shelf.

To monitor and assess the WCDSR, indicator species have been selected using a risk-based approach that considers their inherent vulnerability to fishing, level of targeting and catch taken by fishers, and the amount …

Late Summer Plankton Community Variation In Near Shore Environments, Aidan Jacobs-Walker

Copley Library Undergraduate Research Awards

Phytoplankton communities have profound impacts on ecosystem health and function. In the Southern California Bight, hydrographic conditions play a key role in determining the composition of phytoplankton communities. This study conducted hydrographic and plankton community analyses of the nearshore environment off Dana Point, California, during late September. Similar to other studies in the SCB during fall, we observed weakly stratified, oligotrophic waters dominated by dinoflagellates under 10 μm. However, the recorded plankton abundances onshore vs. offshore deviated from the “green ribbon” typical of the SCB, in which phytoplankton are much more abundant onshore than offshore. Additionally, while the onshore community …

An Automated On-The-Go Unloading System Reduces Harvest Operator Stress Relative To Manual Operation, Travis A. Burgers, Kusha Kamarei, Mukund Vora, Matthew Horne

Mechanical Engineering Faculty Publications

On-the-go unloading improves harvest operational efficiency, but it requires skilled labor because it is challenging and stressful to balance numerous concurrent tasks. Harvest automation reduces workload, stress, and fatigue. The objective of this study was to determine if using a commercially available, automated on-the-go unloading system (Raven Cart Automation TM , RCA, Raven Industries) would reduce operator stress com- pared to manual operation. Nine grain cart tractor operators and six combine operators participated in this study. Operators performed their typical harvest operation, except to alternate on-the-go unloading using RCA or operating manually. Skin conductance (elec- trodermal activity) was measured with …

Weighing The Mind: Cognitive And Emotional Influences On Weight Loss Maintenance In Obesity, Rachel Sochocki

Wayne State University Dissertations

Obesity is a multifaceted and complex disease. Weight loss in efforts to combat obesity often result in weight regain, posing a significant challenge to long-term weight management. This dissertation investigates the cognitive, emotional, and physiological factors contributing to weight loss maintenance, emphasizing the roles of eating behaviors, depressive symptoms, and inflammation. In a retrospective cohort study, data was collected on individuals enrolled in the Michigan Weight Management Program who consented to involvement in this research. The data was collected at baseline, post-weight loss (after 10% weight loss at 6 months), and on one-year and two-year follow-ups. The Yale Three Factor …

Data For: "Polyethylene Polymer Type And Soil Properties Determine Impacts Of Microplastic Pollution On Arugula Growth", Noah P. Walsh, Ella Beaghen, Abigail Kane, Leilani M. Santodomingo, Daniel Watson, Christina S. Baer

First-Year Research Immersion (FRI) Scholarship

From the manuscript abstract:

While microplastics have become a novel pollutant of concern, few studies have directly compared different polymers’ effects on plants. We investigated the effects of high-density (HDPE) and low-density (LDPE) polyethylene on arugula growth. We hypothesized that polyethylene microplastics would inhibit growth and that LDPE would have a greater effect than HDPE due to its branched structure and lower density. We grew arugula (Eruca vesicaria) in plain soil or soil mixed with HDPE or LDPE microplastics. To determine if microplastic effects are dependent on soil quality, we used two kinds of fresh soil and reused one type …

On-Site Estimation Of Total Sugars In Flavored Milk Using A Glucometer, Erwin Oliver V. Fundador, Karyn Thea E. Rivera, Kriza Faye A. Calumba, Noreen Grace V. Fundador

ASEAN Journal on Science and Technology for Development

Sugar has been linked to obesity and chronic diseases. Unfortunately some "healthy products," such as flavored milk, contain high sugar. In the Philippines, such an issue is made worse by local brands not putting nutritional labels on their products. Thus, a cheap, home-based method to measure total sugars should be beneficial. In this paper, we have shown that after incubation with invertase and lactase, a glucometer can be used to measure total sugars in flavored milk on-site. All experiments except the weighing of invertase and lactose were done in a home setting for actual proof of concept. The total sugar …

The E-Liquid Flavorings Cinnamaldehyde, Vanillin, And Ethyl Vanillin Induce Cellular Stress Responses In Human Proximal Tubule (Hk-2) Epithelial Cells, Ashley J. Cox

Theses, Dissertations and Capstones

The use of electronic nicotine delivery systems (ENDS) has become popular in recent years as an alternative to traditional cigarettes. These devices heat and subsequently vaporize e-liquids for inhalation by the user, which allows for the delivery of ingredients such as flavorings, nicotine, and solvents through the vapor. Flavorings used in e-liquids are “generally recognized as safe” (GRAS) for consumption by the Food and Drug Administration (FDA), however there are currently no recommendations on safety regarding the inhalation of flavoring agents. While research characterizing effects of e-liquids and their flavorings is abundant in lung and respiratory tract models, few studies …

The study undertakes a multifaceted analysis that encompasses biomarker sensing technologies, AI-driven biofeedback mechanisms, and haptic devices, focusing on their implications for enhancing proprioception and social interaction among neurodivergent populations. While wearables offer a range of opportunities for societal advancement, a discernable gap remains: a scarcity of consumer-oriented applications tailored to the unique physiological and psychological needs of these individuals. Key takeaways underscore the emergent promise of tailored auditory stimuli in workplace dynamics and the efficacy of haptic …

Female Biology, Jennifer Dever

All USF Faculty Authored Books

Over twenty years ago I developed a course for the upper- level biology major at the University of San Francisco called

Female Biology. This was from what I perceived as a gap in the undergraduate biology curriculum- students were not learning about the evolutionary aspects of being female and studying the specific health-related issues unique to women. The information in the most widely used general biology textbooks written from a male perspective, focuses on research gained from male models by work conducted in male-led laboratories. There still exists a problem with a lack of adequate representation of women in biomedical …
