The Ethical Implications Of Bioengineering Advancements, Mainstream Media Coverage Of Those Developments, And The Future Of Motherhood, Aliff Abad, Katherine Gregory

Publications and Research

How do the media interpret reproductive interventions that involve genetic testing? When a scientist performed the first known genetic editing on twins, Lulu and Nana, he ignored ethical considerations of CRISPR use. This project provides a content analysis based on a review of popular science and newspaper articles. Our interpretation of these articles suggest that there is a lack of critical understanding of this unethical procedure and a similar attitude towards future genetic developments. While the public is curious about the repercussions of genetic editing, not enough focus is applied to the ethics of conducting such a procedure.

Green Roof System Integrated Soil Methods, Jude R. Vallon, Ivan L. Guzman

Publications and Research

Large metropolitan areas like NYC are seeking to integrate sustainability into retrofitting buildings for the development of green infrastructure. Among the many environmental issues of urbanization, the UHI (urban heat island) effect and storm water runoff are of particular interest when it comes building structures. Individual buildings can contribute towards mitigating these effects with implementation of vegetative rooftops, i.e. Green Roofs. Commercial buildings are currently receiving government incentives and new constructions are required to include green roof installations. However, if existing buildings are considering the addition of a green roof on an existing roof, they have to factor in the …

Exploring Secondary Structure In Bacteriophage Programmed Frameshift Elements, Samuel Okabayashi, Sean Mcclory

HON499 projects

Bacteriophages are viruses that infect bacteria and reproduce using host bacterial components. Part of the bacteriophage reproduction is assembly of the tail complex, which requires two assembly chaperone (TAC) proteins. In many phages the TAC’s are produced from a single gene through a non-canonical process called programmed translational frameshifting (PTF). The SEA-PHAGES program has produced hundreds of TAC genes that are accessible through phagesdb, a database of sequenced and annotated phage genomes. The sequences for the TAC gene were gathered from phagesdb and analyzed using ClustalOmega; a multiple sequence alignment (MSA) tool which revealed several positions where total conservation was …

Seminole State College Cure Research Program: From The Classroom To Collaboration, Maya Patrice Byfield Phd

Florida Statewide Symposium: Best Practices in Undergraduate Research

It is believed that if students are taught inductively in their first 2 years, it could induce many of them to seek research experiences later in their academic careers. To do this, we initiated an effort to promote engagement in research topics and faculty development. First, collaboration between one faculty member at SSC and a Principal Investigator at the Sanford-Burnham Institute was developed. This collaboration resulted in the creation of several internships at the Institute for students in the newly developed STEM research class. Second, to increase student engagement, the biology department developed a research focused colloquium series. Each fall …

The Effects Of Erosion Structures On Triplett Creek From The Fall Of 2016, 2017, And 2018, Haylee Winters

Posters-at-the-Capitol

Triplett Creek is a tributary of the Licking River. It runs through Morehead, KY, where we are conducting our research.

The creek was modified in the 1970s but construction was halted before the project was complete. Unfortunately, the result was an increase in overflow and subsequent riverbank erosion. The city installed sediment trap rocks in hopes of slowing down the water and decreasing erosion. We are using drones and photogrammetric software to map the area and compare images of the river to determine erosion rates. The new images will be compared to ones taken in previous years to visualize the …

Panel 9. Paper 9.2: Maintenance Of Water Systems Of Cultural Heritage--Case Studies Along Silk Roads, Jian Feng, Xueqing Yang, Yisi Liu

ISCCL Scientific Symposia and Annual General Meetings // Symposiums scientifiques et assemblées générales annuelles de l'ISCCL // Simposios científicos yy las Asambleas Generales Anuales

Water has become a vital element in studying heritages, since researchers has realized that heritages are not only about sites per se, but also include multiple elements that reflect human social and cultural development along historical evolution, and water is one of the most important sector to study. To study further maintenance of water systems of cultural heritages, it is necessary to understand the authenticity of water which is decided by interactions between human and water into consideration, and notice different interactions would result in different discussion on further water management and preservation, for water systems have been changed and …

A Toolkit For Managing The Ee (Environmental Education) And Esd (Education For Sustainable Development) Continuum, Attiyya Atkins, John J. Pipoly Iii

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Environmental Education (EE) and Education for Sustainable Development (ESD) represent extremes of a global continuum. EE stresses awareness of process about, from and for the environment (Vrasidas 2007). ESD is defined as education empowering communities to acquire best management practices engendering human, social, economic and natural sustainability (UNESCO 2012) and developing their resilience despite environmental changes (Fastenrath et al. 2019). ESD is a critical component of the UN's Sustainable Development Goals (UN 2012), which grew from the Millennium Development Goals (UN 2000). Each park agency should develop research-based educational programs that address both EE and ESD. The ESD must promote …

Effects Of Invasive Species On Post-Fire Ceanothus Spinosus Seedling Establishment, Nina Duchild, Frank W. Ewers, Stephen D. Davis

Featured Research

This study compared seedling establishment of the native chaparral species Ceanothus spinosus in two different burn sites at Pepperdine University following the Woolsey Fire of November 2018. One site was a low-density fuel site, and experienced a “cool burn,” and the other site was a high-density fuel site and experienced a “hot burn.” In the low-density fuel site, fire type-conversion had occurred, resulting in a dominance of exotic species. The high-density fuel site was populated by many native fire-following species and chaparral shrubs, exemplifying pristine post-fire conditions. Initially, I hypothesized that seedling success in the cool burn site would be …

Seedling And Resprout Survival Of Three Chaparral Species Following Woolsey Wildfire, Karagan L. Smith, Stephen D. Davis

Featured Research

Fire is a common natural disaster that effects Southern California. Combined with recent chronic drought, there has been an increase in the damage and frequency of these fires in recent years. Three chaparral species are common to the Pepperdine campus: Malosma laurina, Ceanothus spinosus, and Ceanothus megacarpus. The survival of these native species is essential because they are indicators for the changes that are occurring in our local ecosystem and provide further implications of how our ecosystem responds to natural disaster. Seedling recruitment and resprouting are mechanisms these chaparral species use to reestablish postfire. Postfire data have been recorded …

Post-Fire Soil Microbiome Recovery And Respiration In A Chaparral Ecosystem, Mari R. Irving, Stephen D. Davis

Featured Research

This study characterizes post-fire recovery of microbial and fungal populations adjacent to three keystone chaparral plant species affected by varying burn intensities via systematic measurement of soil respiration. The CO₂ released from soil surrounding Ceanothus spinosus, Heteromeles arbutifolia and Malasma laurina affected by mild, severe or no heat during the Woolsey Fire of November 2018 were monitored and used as an indicator of microbial, fungal, and root activity. We hypothesized that soil which experienced less intense heat would exhibit higher rates of respiration based on preliminary data taken in March 2019. However, the opposite was observed from May through …

Photosynthetic Response Of Pentagramma Triangularis To Summer Desiccation, Brandon R. Grinovich, Stephen D. Davis

Featured Research

Ferns are thought to have been some of the first vascular plants to develop, perhaps on the order of 390 million years ago. Since then, ferns have speciated and developed innovative methods of survival especially in relation to water stress. Research conducted in 2016 by Helen Holmlund showed that eight California fern species fell into four primary classes of survival strategies, one of those being resurrection. Pentagramma triangularis is one of the resurrection-type ferns and is endemic to the western coast of the United States. As P. triangularis desiccates during the summer it enacts a physiological response by which it …

The Impact Of The Woolsey Fire On The Fungus Botryosphaeria Dothidea, Juan Arguijo

Featured Research

Southern California suffered a six-year drought in 2012 through 2018 during which the laurel sumac, Malosma laurina, experienced water stress and the fungus Botryosphaeria dothidea began to kill this plant, causing a massive dieback of this keystone chaparral species in the Santa Monica Mountains. Botryosphaeria is an opportunistic endophytic fungus that invades the xylem of woody type plants and waits till the plant starts to experience stress to proliferate. In November of 2018, the Woolsey fire burned up to 96,000 acres of vegetation. I ran tests at two sites on the Pepperdine University campus, the Baxter Ridge Site which …

Genetic Diversity Of Local Canines Assessed By Derived Cleaved Amplified Polymorphic Sequences, Nicole Benmoshe, Jeremy Seto

Publications and Research

Breeding of the dog, Canis Iupus familiaris, over centuries has given rise to the selection of certain traits including size, shape, coat length, color and many behavioral traits. Inbreeding within dog breeds has resulted in the increase of genetic diseases, many of which are similar to human diseases making the dog an exemplary model organism to study. Using dCAPS (Derived Cleaved Amplified Polymorphic Sequences) we can identify SNPs (Single Nucleotide Polymorphisms) in the dog genome using buccal samples collected from four local dogs of different breeds, both large and small. After performing DNA extractions, PCR (Polymerase Chain Reaction), restriction enzyme …

Cultural Competence: Issues And Benefits In Healthcare Delivery, Tetiana Soloviova, Amina Shahbaz, Fahaneda Hassan, Zoya Vinokur

Publications and Research

The extreme growth of New York State population causes to bring more challenges and opportunities for healthcare organization to provide culturally competent service to meet the need of diverse population. According to data from the US Census Bureau, minority groups are projected to make up nearly 50% of the population by the year 2050 compared with 30% in 2000. Outside of ethnicity, there are also many cultural and social groups with which people identify that may affect how they view or receive healthcare. It is very difficult to provide quality service for a diverse population due to language barriers, health …

The Function Of Ecdysone And Inhibiting Programmed Cell Death In Death Class Iii Neurons Of Drosophila Melanogaster, Nikolas Richard Likourentzos

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The inhibition of programmed cell death is a factor believed to be responsible for the survival of cancer cells. Using Drosophila as models, factors contributing to the process of programmed cell death can be studied. Neurons die throughout Drosophila melanogaster development to allow the addition of new neurons. The groups of neurons programmed to die are Death Class I neurons, Death Class II neurons, and Death Class III neurons. Ecdysone is a hormone responsible for the timing of programmed cell death (PCD) in the Death Class neurons. Elevated levels of ecdysone are associated with the initiation of PCD of Death …

Heteromeles Arbutifolia Associated Post-Fire Soil Microbiome Recovery And Respiration In A Chaparral Ecosystem, Gabrielle Boeger, Lauren Dedmon, Emma Thomsen, Alexander Soloniuk

Featured Research

The purpose of this post-Woolsey Fire project is to examine the relationship between soil respiration in areas of cool burns and hot burns relative to individuals of Heteromeles Arbutifolia. It was hypothesized that the soil subjected to a cooler burn would have greater respiration rates due to increased survival of microorganisms compared to a hotter burn. An Li-6800 CO2 Flux Chamber was used to collect measurements for several replicates. Significance was detected in the “Day 3” data, with the soil respiration higher at the cool burn site. Temperature and soil flux also varied directly. In the future experiments including increasingly …

Soil Respiration In Burned And Unburned Sites Of The Santa Monica Mountains, Sydney C. Jones, Micah S. Kim, Sierra H. Ball, Stephen D. Davis

Featured Research

Soil respiration (the flux of CO₂ released by the soil due to microbial and root respiration and organic matter decomposition) can be affected by fire (Qu et al., 2009, Richards et al., 2012, Ryu et al., 2009). After the 2018 Woolsey Fire in the Santa Monica Mountains, we hypothesized that soil respiration would be greater in unburned soil than in burned soil. This is because fire can decrease soil nutrient concentration, which could decrease soil microbial concentration and also because fire could burn and kill soil microbes and roots. To test this relationship, we recorded soil respiration on three …

Physiological Performance Of Ceanothus Spinosus In Hot Burn And Cool Burn Sites, Rishi Gattu, Christian Hill, Chris Kulpaca

Featured Research

After the Woolsey Fire, many fire adapted plants will resprout. However, increased fire frequency has negatively impacted the reproduction of many native species, while enhancing the survivorship of many invasive species. We compared the physiological performance of Ceanothus spinosus resprouters in areas that burned hotter compared to areas that burned cooler. We hypothesized that resprouters in hotter burn sites would have better physiological performance than resprouters in cooler burn sites. The resprouters in hotter burn sites would have better performance because of decreased competition from invasive species. We measured physiological performance using a Li-Cor LI-6400, specifically photosynthesis, transpiration, and stomatal …

Comparative Fitness Of Post-Fire Transplant Stipa Pulchra And Wild Stipa Pulchra In Competition With Avena Fatua, Ashley Bonin, Madison Cook, Sara Head

Featured Research

In the Spring Semesters of 2016 and 2017, research was conducted on the relative fitness of Stipa pulchra in the transplant garden on the Drescher campus at Pepperdine University. The first study in 2016 examined the fitness of Stipa pulchra and Avena fatua in the transplant and wild gardens after a five year drought in California. In the results of this experiment, the hypothesis was supported when observing that the wild S. pulchra depicted higher fitness that the transplant S. pulchra in areas of stomatal conductance, height, water potential, percent sun and dark-adapted fluorescence. The second study in 2017 investigated …

A Survey Of Post-Fire Chaparral Species’ Densities Using Point Quarter Sampling, Emma C. Stenz, Brandon R. Grinovich, Catherine H. William, Michael E. Gayed, Stephen D. Davis, Grace Palmer

Featured Research

The purpose of this observational study was twofold: to add to the existing data regarding the plant species composition of the Pepperdine hillsides and to set in place a foundation for post-fire chaparral recovery studies that will ensue over the coming years through various programs and classes. The 2018 Woolsey Fire burned nearly all of the natural environment surrounding Pepperdine University and the greater Malibu region, so it is a matter of urgency to take this opportunity to learn more about how this natural environment of the chaparral responds to a catastrophic event like fire. We focused primarily on facultative …
