Locating Vitamin D Receptors (Vdrs) In Annual Killifish, Austrofundulus Limnaeus, Rosy Tanori May 2024

Locating Vitamin D Receptors (Vdrs) In Annual Killifish, Austrofundulus Limnaeus, Rosy Tanori

Student Research Symposium

Austrofundulus limnaeus, a species of annual killifish found in unpredictable temporary habitats in South America, has a profound ability to survive long periods without water and oxygen. This tolerance is associated with the ability to enter metabolic dormancy associated with diapause. Entrance into diapause and tolerance of environmental stress is governed by an interplay of genetic and environmental factors. The vitamin D receptor (VDR) is among these factors and plays a crucial role in determining if an embryo will enter diapause or actively develop. My work aims to identify the genomic locations of VDR proteins in the A. limnaeus genome …


Describing Shen & Shen Ming Via A Hybrid Quantum Computational Model, Alex M. Cullen, Johnny Lemau May 2024

Describing Shen & Shen Ming Via A Hybrid Quantum Computational Model, Alex M. Cullen, Johnny Lemau

Student Research Symposium

Definitions for Traditional Chinese Medicine (TCM) terminology within the context of quantum biology (QB) have recently been proposed. These definitions aim to elucidate concepts such as qi meridians in TCM. Our study presents a hypothesis that seeks to provide an operational definition for Spirit (Shen) and Bright Spirit (Shen Ming) in TCM via a scoping review. We propose that Shen represents physical, phenomenological proto-consciousness/consciousness in the forms of computation, such as singular particles/bits/qubits, computers, organisms, or computational strategies, whereas Shen Ming may refer to emergent, quasi-physical meta-proto-consciousness/consciousness formed by coherent relationships of multiple orchestrated/integrated units of computation; manifesting itself as …


Common Use Herbicides Increase Wetland Greenhouse Gas Flux Rates, Christopher Walsh '25 May 2024

Common Use Herbicides Increase Wetland Greenhouse Gas Flux Rates, Christopher Walsh '25

Biology Student Scholarship

Herbicides have been found to affect greenhouse gas emissions from aquatic systems, attributed to changes in vegetation or microbial metabolic processes. Two of the most commonly used herbicides worldwide are glyphosate and 2,4-Dichlorophenoxyacetic acid (2,4-D). Due to both the increased use of mixed herbicides and global intensification of agriculture, wetlands are receiving increasing amounts of glyphosate and 2,4-D. Both glyphosate and 2,4-D are primarily degraded by 46 microorganisms, where certain species use them for nutrients and other species are inhibited by their toxicity. Even minor herbicide-induced shifts in wetland microbial communities can potentially alter ecosystem function and GHG emissions. This …


The Effect Of Temperature On The Invasive Asian Needle Ant, Kaylee Mulligan '25 May 2024

The Effect Of Temperature On The Invasive Asian Needle Ant, Kaylee Mulligan '25

Biology Student Scholarship

The Asian Needle Ant (Brachyponera chinensis) is an invasive species currently spreading on the Eastern Coast of the United States. They were first reported around the 1930s in Florida and have since migrated to Massachusetts. As an invasive species, this pest originating from Asia has a negative impact on environment ecosystems and other species of ants. Asian Needle Ants displace resident ant colonies, taking over nesting sites by consuming food sources and decreasing the amount of space other ant colonies can use. They are also known to have a sting that contains venom more likely to result in …


Sea Surface Temperature Influence On Tropical Storms And Hurricanes, Elise Leroux '26 May 2024

Sea Surface Temperature Influence On Tropical Storms And Hurricanes, Elise Leroux '26

Biology Student Scholarship

Hurricanes are both dangerous and difficult to predict because of the various factors that influence the size and intensity of storms, where sea surface temperature (SST) is one of the most relevant variables. As temperatures are increasingly rising due to climate change, the effect on storm size, intensity, and frequency is going to be greater. There have been many studies how individual storms are affected, but less so on the overall frequency of hurricanes. This study assesses the number of hurricanes each year in comparison to the SST and the average wind speed of each hurricane. I predict that years …

The Effect Sea Temperature Has On Coral Reef Health In The Great Barrier Reef, Elizabeth Glasspool '26 May 2024

The Effect Sea Temperature Has On Coral Reef Health In The Great Barrier Reef, Elizabeth Glasspool '26

Biology Student Scholarship

Coral reef bleaching can happen for many different reasons including storms, disease, sediment and salinity changes, and of change in climate. Mass bleaching is typically a cause of increasing sea temperature in a certain area. Mass bleaching typically kills off many different species of coral. This is detrimental to a large portion of biodiversity, especially in a marine atmosphere. In 2016, records show that it is a record high ocean temperature which led to widespread coral bleaching on Australian reefs. This was part of the third global bleaching event declared by the National Oceanic and Atmospheric Administration (NOAA). At the …


The Effect Of Integrated Pest Management On Nutrition Of Bee Collected Pollen, Kaitlyn Bresnahan '25 May 2024

The Effect Of Integrated Pest Management On Nutrition Of Bee Collected Pollen, Kaitlyn Bresnahan '25

Biology Student Scholarship

Honey bees are the world’s most commercially valuable pollinators, and they face many threats. The greatest challenge facing honey bees is Varroa mites, parasitic mites that feed on bees’ fat bodies, killing bees and spreading diseases. While chemical treatments are available to stop the spread of mites, these treatments are insecticides, which are not ideal to put in a hive of insects. A popular organic method of mite management is using drone comb. Drone brood is preferentially chosen by mites for ovipositing and development because of its larger size and longer development time, so removing drone brood can drastically reduce …


The Effect Of Population Density On Harmful Algal Blooms In Southwest Florida, Emma Barry '25 May 2024

The Effect Of Population Density On Harmful Algal Blooms In Southwest Florida, Emma Barry '25

Biology Student Scholarship

Karenia brevis is a species of algae native to the Gulf of Mexico. Times when its growth becomes uncontrollable are called harmful algal blooms (formerly called “red tide events”), and they are often caused by increased nutrients in the water. These excessive nutrients come from watersheds and runoff that contain anthropogenic materials like fertilizer, and the phosphate and nitrogen in fertilizers catalyze the growth of algae. As population density in Florida increases, fertilizer runoff increases as well. Harmful algal bloom events are dangerous to both humans and the environment. Thick layers of algal growth on the water’s surface create “dead …

Mathematically Modeling How Trapping Regimes That Target Specific Crayfish Life Stages Impact Removal Efficacy, Rini Pattison

Seaver College Research And Scholarly Achievement Symposium

The red swamp crayfish, Procambarus clarkii, is an invasive species introduced into several streams within the Santa Monica Mountains (SMM) in Southern California. Crayfish predation decimates native aquatic species. Thus, the Mountains Restoration Trust (MRT) and Environmental Restoration Group have worked to remove crayfish through regular trapping in Malibu Creek.

To aid conservation efforts, former SURB students William Milligan and Dev Patel developed mathematical models of crayfish removal efficacy. Milligan created a differential equation model of how crayfish removal affects local newt populations. Patel expanded Milligan’s crayfish model by creating a discrete model of the crayfish life cycle that newly …

Making The Connection: How Membrane Contact Sites Have Changed Our View Of Organelle Biology, G. Voeltz, E. Sawyer, G. Hajnóczky, W. Prinz Jan 2024

Making The Connection: How Membrane Contact Sites Have Changed Our View Of Organelle Biology, G. Voeltz, E. Sawyer, G. Hajnóczky, W. Prinz

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The view of organelles and how they operate together has changed dramatically over the last two decades. The textbook view of organelles was that they operated largely independently and were connected by vesicular trafficking and the diffusion of signals through the cytoplasm. We now know that all organelles make functional close contacts with one another, often called membrane contact sites. The study of these sites has moved to center stage in cell biology as it has become clear that they play critical roles in healthy and developing cells and during cell stress and disease states. Contact sites have important roles …


Female Biology, Jennifer Dever Jan 2024

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 …

Investigating Scube3 Nuclear Localization In Presence Of Doxorubicin Treatment In Triple Negative Breast Cancer Cells, Lillian Ergle Jan 2024

Investigating Scube3 Nuclear Localization In Presence Of Doxorubicin Treatment In Triple Negative Breast Cancer Cells, Lillian Ergle

Merge

Signal peptide-CUB-EGF-like domain-containing protein 3 (SCUBE3) is a glycosylated secreted protein. Prior to its secretion, SCUBE3 localizes in the cytoplasm. We observed that SCUBE3 protein trans-localized to the nucleus following Doxorubicin (DOX) treatment. DOX is one of the strongest chemotherapeutic agents and the first-line drug used in breast cancer treatment. SCUBE3 structural analysis showed that it lacks a DNA binding domain. Based on this observation and other preliminary data, we hypothesized that nuclear SCUBE3 protein promotes the survival of cells against Doxorubicin treatment. To investigate this hypothesis, we made a wild-type construct and three constructs with mutated nuclear localization sequences …

How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck

Undergraduate Research Posters

El-Niño Southern Oscillation (ENSO) causes regional changes in climate and has been found to have varying effects on the survival, fecundity, and recruitment of migratory songbirds. This study seeks to better understand the effect of ENSO on the fecundity of Virginia-breeding Prothonotary warbler (Protonotaria citrea; PROW), a neotropical migratory songbird. PROW breed in the Eastern United States and spend the non-breeding season primarily in Panama and Colombia. Ongoing research in Virginia has found a positive relationship between spring precipitation and predicted number of PROW fledgelings during La Niña, but the opposite during El Niño. To better understand this relationship, we …


Carry-Over Effects Of Climate On Prothonotary Warbler (Protonotaria Citrea) Feather Quality, Alyssa N. Spasic, Dan Albrecht-Mallinger, Lesley Bulluck Jan 2024

Carry-Over Effects Of Climate On Prothonotary Warbler (Protonotaria Citrea) Feather Quality, Alyssa N. Spasic, Dan Albrecht-Mallinger, Lesley Bulluck

Undergraduate Research Posters

Avian species have inspired numerous studies on ornamentation, exploring its role in intra- and intersexual selection as a marker for individual quality. Male birds have been the focus of most of these studies while females, which can also display ornamentation, have been studied less. Coloration achieved through molt, particularly carotenoid-based pigments, requires energy derived from food resources. As climate affects insect abundance, there may be a link between climate conditions during molt and feather quality the following season. We assessed the relationship between temperature and precipitation during molt and female Prothonotary Warbler (Protonotaria citrea) breast and crown feather reflectance metrics …
