Evaluation of the behavior of yttrium and lanthanum in surface seawater
Presentation Year: 2022
The biogeochemical cycling of trace metals in the ocean, as the name implies, is a cycle that describes the complex interplay of a broad range of physical and chemical processes that govern the behavior of metals in the ocean. Input of trace metals into surface ocean water can come from any of several sources including anthropogenic input from the continental surface, airbound particles, or upwelling from the deep ocean, among others. Metal concentrations for yttrium and lanthanum were obtained from surface Pacific Ocean water and the data sets were interpreted to evaluate the behavior of each of the two metals in the context of this cycling.
Functional impact of alternative splicing on the transcriptomic landscape and fate of multipotent skeletal stem cells and osteosarcoma
Presentation Year: 2022
Greater than 90% of all protein-coding genes in the human genome undergo post-translational alternative splicing (AS), giving rise to many unique isoforms from a single gene. Our work with human skeletal stem cell (hSSC) has demonstrated the need to examine AS as it relates to cancer, development, aging, skeletal regeneration and skewing of hSSCs towards non-skeletogenic lineage fates. Here we explored the relationship between AS and function of hSSCs. Using RNA microarray technology we discovered RNA-binding proteins involved in hSSC function; inhibition of these proteins prevents differentiation and formation of osteosarcoma. Our current work reveals other essential roles of AS in hSSCs.
Great Egret (Ardea alba) Abundance Between the Brackish Pond and Restored Tidal Habitat During High Tide and Low Tide
Presentation Year: 2022
Brackish and tidal habitats are one of many habitat types that support an extensive amount of bird populations in wetland ecosystems (Stolen et al. 2007). However, tidal fluctuations can be of an influence in abundance for Great egrets between many habitat types. The objective of this study is to understand if Great egret abundance is influenced between the brackish pond and the restored tidal habitat as well as certain tide periods of the day.

Habitat Use of Pacific Banana Slugs in Natural Recreational Areas in Humboldt County
Presentation Year: 2022
The goal of this study was to determine whether factors such as vegetation type, temperature, shrub canopy coverage, and tree canopy coverage contribute to Pacific banana slug habitat use in natural recreational areas in Humboldt County, CA.
High-Touch, Low-Tech: Managing Postpartum Engorgement
Presentation Year: 2022
Chest/breast engorgement is a common source of pain in the postpartum period. According to Huda et al. (2021) breast engorgement and pain are the leading cause of early discontinuation of breastfeeding. Breastfeeding is life-saving, cost-effective, sustainable for the planet, and keeps parents, and babies healthier. A high-touch, low-tech approach to the management of engorgement can be utilized through gentle breast massage and hand expression. The implementation of supportive patient-centered care can increase in-hospital breastfeeding rates. Human milk is the optimal first food to support overall health and provide food security for infants in any situation.
How Moon Illumination, Cloud Cover, and Temperature Influence Capture Rates for Small Mammals
Presentation Year: 2022
This research project uses small mammal trapping data that was collected over the summer of 2021 on Green Diamond Resource Company land in Humboldt and Del Norte County. There was a total of 841 captures (nocturnal = 694, diurnal =147) over the course of 39 trap nights. Data was extracted and analyzed to determine if there was any correlation between moon illumination levels and capture rate success. This study uses diurnal species as a control, however both diurnal and nocturnal species may be influenced by temperature.
Human Disturbance Influences the Long-billed Curlew’s Foraging Behavior (Numenius americanus)
Presentation Year: 2022
There have been a lot of studies done on the Long-billed Curlew around the Humboldt bay (Colwell and Mathis 2001, Leeman et al. 2001, Mathis et al. 2006) however not many on the impact of humans on them. This study looked at whether humans are affecting the foraging behavior of the Long-billed Curlew around Humboldt bay.
Humboldt In The Time Of COVID Digital Archive
Presentation Year: 2022
This poster serves as a visual presentation of some of the items collected from the community in the Humboldt in the time of COVID digital archive. Submissions in the archive have mainly been audio, video, or written submissions but many of the images also show some of the life of Humboldt residents on and off campus.
Hummingbird Flower Use at the Humboldt Botanical Garden
Presentation Year: 2022
My research investigated further into the feeding preferences of hummingbirds, particularly on individuals in the Humboldt Botanical Garden. I focused on how hummingbirds select flowers to feed on based on color, as well as how they select which garden patch they feed at.
Identification of a Type 1 Regulatory T Cell Master Regulator
Presentation Year: 2022
Type 1 regulatory T cells (Tr1s) are critical for regulation of autoimmunity and acceptance of hematopoietic stem cell transplants. One major limitation of Tr1 research is the lack of known master regulator, which is a transcription factor that has essential roles in both differentiation and function of the cell type. My research leverages CRISPR-Ca9-induced knockouts and in vitro Tr1 differentiation to screen potential Tr1 master regulators.
Improving Health Outcomes for Rural Parent Caregivers of Neurodiverse Children
Presentation Year: 2022
The prevalence of developmental disabilities (DD) is about 17% in the United States, with rates higher in rural communities (Robinson et al., 2017). Children with DD (also known as "neurodiverse") have individual strengths and face unique challenges. Due to adversity in accessing specific and much-needed support, parent caregivers often experience clinical levels of parenting stress (Davis & Carter, 2008, as cited in Roberts et al., 2019). Parents in rural communities are particularly affected. Chronic, unaddressed stress can lead to worsened mental and physical health including depression, hypertension, and cardiovascular disease (Robinson et al., 2017).
The goal is clear: to incr
Increase Cervical Cancer Screening Participation in a Rural FQHC
Presentation Year: 2022
Cervical cancer (CC) is the fourth most common cancer and typically caused by human papillomaviruses (HPV). The American Cancer Society’s preferred screening method is HPV testing, which is detectable in the vagina. The FDA has not approved this test, but some private labs offer this screening with patients collecting their own vaginal swab. The goal is to increase participation in CC screening in patients who decline traditional testing. Most CC cases are in patients who are not up to date on screening frequency or never received screening before. If positive on self-swab, patients are more likely to follow up, receiving the care they would never have received if not given this option.
Influence of Canopy Cover on Artificial Refugia Color Selection in Pacific Tree Frogs (Pseudacris regilla)
Presentation Year: 2022
I studied Pacific Tree Frogs (Pseudacris regilla) at the Arcata Marsh to observe how canopy cover in the environment would influence how the frogs select microhabitats. Pacific Tree Frogs actively use color cues when selecting microhabitats and will use artificial refugia when it is available. Using PVC pipes painted either white or brown as artificial refugia, I set up one white and one brown PVC pipe sample at four sites around the Butcher Slough Log Pond. Two sites had no canopy cover while the other two had high canopy cover. I then tested whether Pacific Tree Frogs would select white or brown artificial refugia under the influence of low or high canopy cover in the environment.
Influence of Human disturbance on the ranging patterns of wildlife on college campuses
Presentation Year: 2022
In a world with increasing urban sprawl wildlife is finding habitat remnants of green spaces such as college campuses. These campuses provide many green spaces, anthropogenic food sources, and a unique set of challenges for wildlife to face. My study looked at how wildlife species on the campuses of Cal Poly Humboldt and College of the Redwood are responding to the human disturbance rates across the two campuses.
Institutional Autonomy Support Predicts College Student's Achievement Goals Through Psychological Need Satisfaction
Presentation Year: 2022
We explored the role that instructors play in predicting college student's achievement goals during the COVID-19 pandemic. Achievement goals help us explain the motives behind engagement. Certain types of goals tend to be more adaptive than others. We predicted that greater institutional autonomy support would predict greater psychological need satisfaction. In turn, psychological need satisfaction would predict, respectively, greater mastery approach goals and lower performance-avoidance goals. We found partial support for our hypotheses, yet our findings highlight the importance of encouraging students to self-regulate and explore their own interests.
Investigating Shotgun shell and wad waste around Humboldt Bay
Presentation Year: 2022
Shotguns are often used for hunting and when they are fired, they produce a plastic wad and shell that are ejected and often left behind. In order to estimate the abundance of shotgun wads and shells, eight randomly selected sites around Humboldt Bay were sampled once each during the month of March 2022. The sites sampled included the beach and bay side of the Samoa Peninsula, Arcata, and Eureka. At these selected sites, 400-m2 was inspected for wads and shells. While sampling at each site, trash was collected and weighed. Only one shotgun wad and one shell was collected at two different sites, for an abundance of 0.25 wads and shells per 100 m2, and an average of 0.26 kg of trash per 100 m2
