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 …


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 …


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 Jan 2024

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 …


Ungrading: Reflections Through A Feminist Pedagogical Lens, Erin M. Eggleston, Shelby Kimmel Dec 2023

Ungrading: Reflections Through A Feminist Pedagogical Lens, Erin M. Eggleston, Shelby Kimmel

Feminist Pedagogy

Ungrading is a pedagogical approach in which no grades are given on any assignments. Instead, students are provided with many opportunities to submit work and gain feedback. The goal is to shift student focus from achieving a grade to growth as a learner and a person. As instructors, our ungrading approach utilized personalized learning plans, checkpoint reflections, and student-professor learning conferences to put agency in the hands of our students. We employed this method in upper-level biology and computer science courses and provide critical reflections here regarding our experiences and the connections between this approach and feminist STEM pedagogy tenets. …


Leafy Sea Dragon, Phycodurus Sp., Kennedi X. Light Sep 2023

Leafy Sea Dragon, Phycodurus Sp., Kennedi X. Light

PANDION: The Osprey Journal of Research and Ideas

Artist Statement

Leafy sea dragons, Phycodurus sp. are part of the Syngnathidae family. Syngnathidae is a genus made up of seahorses, pipefishes, and sea dragons. All three of the species are known to have beautiful patterning. However, leafy sea dragons got their name from their leafy appendages like their fins and limbs. The reason I chose to draw a leafy sea dragon is due to my own interest in astrobiology. Astrobiology is the study of life in the universe and astrobiologists look for signs of life within the universe. I would like to be an astrobiologist one day and focus …

The Effect Of Integrated Pest Management On Honey Bee Behavior And Colony Level Health, Kaitlyn Bresnahan Jul 2023

The Effect Of Integrated Pest Management On Honey Bee Behavior And Colony Level Health, Kaitlyn Bresnahan

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, which are 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 …


Suitability And Nutritional Analysis Of Spotted Lanternfly Habitats, Kathryn Hickey Jul 2023

Suitability And Nutritional Analysis Of Spotted Lanternfly Habitats, Kathryn Hickey

Biology Student Scholarship

The spotted lanternfly is an invasive bug that has recently started taking over the Northeastern US, and has even made it to Rhode Island. Although this species is intriguing with its bright red back and spots, it is hurting native plant species and the agriculture industry by feeding on crops, like grapes and cherries. It uses a tongue-like mouthpart to pierce through the plant and feed directly on the sap inside. This punctures plant stems and causes them to drip sap, wither, and even mold. The lanternfly’s most preferred host plant is the invasive tree-of-heaven, which grows and spreads quickly …


Effect Of Decreased Snowfall During An Atypical Winter On A Rare Butterfly’S Host Plant, Breelyn Gilbert Jul 2023

Effect Of Decreased Snowfall During An Atypical Winter On A Rare Butterfly’S Host Plant, Breelyn Gilbert

Biology Student Scholarship

In the Northeastern US, one result of climate change is decreased snowfall and earlier snowmelt. Such changes can alter the relationship between climate and the timing of cyclical biological phenomena— the phenology of organisms. This is especially concerning for species that interact with one another such as butterflies and their host plants. For this study, I focused on the host plant of the rare frosted elfin butterfly. The frosted elfin is a species of concern in RI, MA, and CT, among 8 other states, and they are a host plant specialist only laying eggs on yellow wild indigo (Baptisia …


Diversity Of Bees In Trees And Their Foraging Preferences On An Urban College Campus, Aidan Castricone Jul 2023

Diversity Of Bees In Trees And Their Foraging Preferences On An Urban College Campus, Aidan Castricone

Biology Student Scholarship

Pollinators collect nutrients from blooming flowers; pollen provides proteins and fats, nectar provides carbohydrates. The few plants that bloom during early Spring are trees such as crabapple (Malus sp). Current research however, mainly focuses on pollinators that forage on the ground and overlooks pollinators foraging in the canopy of trees. Past research showed increased generalization of pollen foraging in bees as seasons move from spring to summer. Here I identified which bee species forage in the canopy on Providence College campus and will analyze the pollen collected using microscopy. This data can inform more specific research on diet breadth, …


Does Artificial Lighting Cause Sea Turtle Hatchling Disorientations?, Kate Hickey May 2023

Does Artificial Lighting Cause Sea Turtle Hatchling Disorientations?, Kate Hickey

Biology Student Scholarship

Sea turtle hatchlings run into obstacles from the minute they emerge from their shell. They have a 1 in 1,000 survival rate and new obstacles are on the horizon. Coastal development is increasing and is not planning on slowing down. It supports and funds tourism, but has some negative implications on the wildlife that uses this area, like sea turtles. A particular problem with development is the artificial lighting it emits which is effecting sea turtles nesting. When the hatchlings emerge from the nest, they use the horizon and moon to guide them in the direction of the sea. The …


Precipitation Effects On Butterfly Species Richness, Maggie Ritchie May 2023

Precipitation Effects On Butterfly Species Richness, Maggie Ritchie

Biology Student Scholarship

Butterflies are important pollinators that have been impacted due to climate change(1). Studies have looked at how the increasing temperatures and precipitation due to climate change may be playing a role in decreasing populations among some species in Mediterranean climates(2). However, the effects of precipitation have not been considered when looking at changing butterfly populations around the United States. Therefore, increasing precipitation amounts due to climate change may contribute to the decreasing populations of butterflies in Massachusetts.BIO 340 final project


Land And Energy, Devan Viani May 2023

Land And Energy, Devan Viani

Biology Student Scholarship

Land use has and will continue to be a complicated topic. We need land to succeed as a country and a species, but it is equally as important to keep the land as pristine as possible to not affect natural ecosystems. As population continues to increase, urbanization and economic growth has inevitably had an impact on climate change.¹ Parallel to an increase in land development is an increase in power generation. As cities grow, technology evolves, and energy use goes up. With this increase in technology, new sources of power generation are emerging. While fossil fuels have always been the …

Does More Pollen Mean More Sneezing?, Diraliz Cruz

Biology Student Scholarship

Every year millions of people suffer from seasonal allergies, according to the CDC about 25% of adults have to deal with these allergies. Pollen comes from all different things like trees, grasses, and weeds and as climate change increases annually the amount of pollen released into the air also increases. Research has shown that climate change has specifically impacted the amount of birch and oak pollen released annually. Although there is data to show that there has been an increase in pollen release there is little to no information on if the prevalence of allergies has increased or decreased along …


Effect Of Natural Disasters On Coastal Human Populations Of The Southeastern U.S., Caitlin Mchugh May 2023

Effect Of Natural Disasters On Coastal Human Populations Of The Southeastern U.S., Caitlin Mchugh

Biology Student Scholarship

Due to climate change, extreme weather events and natural disasters are becoming more prevalent, and the severity of these events is increasing (Sheldon & Zhan, 2022). Over the last 40 years, the number of billion-dollar natural disasters has gone up. The U.S, averaged 3 billion-dollar disasters per year in the 1980s compared to the average 13 per year in the 2010s (USAFacts, 2023). With natural disasters comes loss of life, infrastructure, and resources that can leave a physical and economic toll on communities for many years if not generations. While some global studies have found that natural disasters increase households’ …


Element Levels In Soil Depend On Elevation, Sean Harris May 2023

Element Levels In Soil Depend On Elevation, Sean Harris

Biology Student Scholarship

Elements, such as arsenic, copper, phosphorus, and calcium, in soil can help biological processes if content levels are not too low or excessive. Arsenic in soil is toxic at high levels and so too much is harmful to vegetation. Copper is important for plants because it helps with chlorophyll and seed production. Phosphorus helps with plant growth, especially for new seedlings. Calcium in soil is not completely needed at high levels, but it does strengthen plants’ health. However, with factors such as different environments, average precipitation levels, and elevation levels in different counties in the Northeast, element content level differ. …


The Influence Of Sampling Frequency On Bee Species Richness, Courtney Caccamo May 2023

The Influence Of Sampling Frequency On Bee Species Richness, Courtney Caccamo

Biology Student Scholarship

As one of Earth’s most valuable pollinators, bees provide important pollination services to wild plant species and crops alike (Winfree 2010). But, in recent years, bee populations appear to be declining due to a variety of anthropogenic drivers (Potts et al. 2010). Quantifying the extent of bee population decline is difficult because there is currently a lack of a standardized protocol for how best to survey bee populations (Tepedino & Portman 2021). One of the commonly used survey methods is pan trapping, which involves leaving out yellow, white, and blue bowls filled with soapy water to passively sample the species …

The Effect Of Water Temperature On Tiger Shark Location, Philip Gelso

Biology Student Scholarship

The tiger shark is a keystone species in its ecosystem. As an apex predator, the tiger shark keeps the entire ecosystem in balance such as maintaining seagrass and coral reef habitats. The rise of ocean surface temperatures have become an issue over the past decades due to the increase in energy from the sun trapped by greenhouse grasses. This change in ocean surface temperature can have detrimental impacts on the ocean environment and the life cycles of many species including the tiger shark. Therefore, this project evaluates the change in location of tiger sharks in relation to water temperature.BIO …


The Impact Of Age And Catch Location On The Mortality Rates Of Striped Bass, Owen Finnegan May 2023

The Impact Of Age And Catch Location On The Mortality Rates Of Striped Bass, Owen Finnegan

Biology Student Scholarship

Striped bass are one of the most popular and sought-after gamefish in the United States for recreation and commercial fishermen. This popularity comes from their size, with many fish reaching 40+ pounds, a prominent dish in seafood restaurants, and their expansive habitat as they inhabit waters from Florida to Canada (1). During the late 1970s/80s, the population began sharply declining due to overfishing, and governments enacted regulations to stabilize the population (1). However, as of 2020, overfishing is still occurring, and regulations are continuously evolving (1). Each state has their own rules and regulations for possessing striped bass for commercial …

The Effect Of Nuclear Power On Carbon Intensity, Lukas Mullaney

Biology Student Scholarship

The world is currently facing one of the biggest threats to the environment in its history: the warming of the Earth’s surface due to climate change. One major contributor is the release of greenhouse gases, such as carbon dioxide, into the atmosphere by humans. To reduce these emissions, countries are making a concerted effort to invest in more sustainable energy sources. Nuclear power is one green energy source that can potentially support the transition to lower carbon emissions. Nuclear power plants release no carbon emissions during the generation of electricity. The only emissions are a result of maintenance, such as …


Extranodal Tumors And Chromosomal Abnormalities Associated With Non-Hodgkin Lymphoma In T(14;18)-Positive Patients, Alexis Finch May 2023

Extranodal Tumors And Chromosomal Abnormalities Associated With Non-Hodgkin Lymphoma In T(14;18)-Positive Patients, Alexis Finch

Honors Theses

Nebraska is mostly an agricultural state with a non-Hodgkin lymphoma (NHL) incidence rate of 20.1 per 100,000 individuals, which is greater than the US incidence rate of 19 per 100,000 individuals. It is possible that the higher incidence rate in Nebraska is due to an increase in pesticide usage. Pesticide exposure is linked to t(14;18), a genetic translocation involving the BCL2 gene that regulates apoptosis. The dysregulation of apoptosis could contribute to the proliferation of NHL. This exploratory study utilized the Nebraska Lymphoma Study Group, which consists of patients with non-Hodgkin lymphoma, Hodgkin disease, or some other neoplastic hematologic disorder …


Understanding The Expression And Role Of Pros-1 In The Male Gonad Of C. Elegans, Jack Bozik Apr 2023

Understanding The Expression And Role Of Pros-1 In The Male Gonad Of C. Elegans, Jack Bozik

Undergraduate Theses

The gene pros-1 is a transcription factor that is highly expressed within neuronal sheath cells, glial cells, and excretory canal cells. pros-1 plays a role in cell determination of those cell types in the nematode C. elegans, which promotes organismal development. But the degree to which pros-1 presence is important is still not fully understood, because there are many genes involved in development that when mutated or damaged can result in unexpected phenotypes or even total loss of function to a certain developmental mechanism. What makes pros-1 valuable to research is that it is a functional homologue to a …

Faculty Mentor, Dr. Laura Williams, Biology

Predatory bacteria hunt and kill other bacteria, including pathogens that cause disease in humans, which makes them a promising alternative for treating antibiotic-resistant bacterial infections. Currently, it is unknown whether and how pathogens evolve resistance to predation. To investigate this, we are studying interactions between E. coli, which is a model organism for pathogenic bacteria, and predatory Bdellovibrio. When we co-cultured E. coli with a particular strain of predatory Bdellovibrio, we observed the emergence of predation-resistant E. coli that had reduced susceptibility to killing …
