The aim of this study was to examine the relationship between tide height and the use of mudflats and pastures by long-billed curlews, with a focus on foraging behavior. Six mudflat sites and five pastures sites were used for data collection using scan sampling during peak high and low tides. Flock size and percent foraging were recorded during each scan, then used to determine use of each site type during high and low tides.
Effects of Trail Surface on Nighttime Mammal Space Use in a Forest Reserve

Recreational trails are widespread features of protected forests and represent a pervasive but understudied form of linear disturbance to wildlife. Although road effects on mammals are well documented, far less is known about how variation in recreational trail infrastructure influences mammal space use, particularly during periods of reduced human activity. Body mass is a fundamental ecological trait linked to movement capacity and home-range size, and may mediate responses to trail surface type.
We hypothesize that the effects of trail surface on nighttime mammal space use are mediated by body mass, such that large-bodied mammals are less constrained by paved trail segments than medium-bodied mammals. If this hypothesis is supported, we predict that (1) large-bodied mammals will be detected more frequently along paved trail segments than unpaved segments, whereas (2) medium-bodied mammals will be detected less frequently along paved segments relative to unpaved segments. We further predict that the magnitude of difference in detections between surface types will be greater for medium-bodied species.
We will deploy 10 motion-activated cameras rotated among 30 systematically spaced sampling locations (N = 30; 15 paved and 15 unpaved) along 3.432 km of the Elk River Trail in Headwaters Forest Reserve, California, USA, over a 6-week period. Independent nighttime detections will be modeled using generalized linear models to evaluate the interaction between trail surface and body-size class. This study will clarify how recreation infrastructure interacts with species traits to influence mammal space use in protected forests.

Engineering Ionically Crosslinked Alginate-Gelatin Granular Hydrogels for 3D Cell Culture
Presentation Year:2026
Marcus
Barela,
Undergraduate Student,
Chemistry
3D cell culture substrates often require complex, costly chemical modifications, limiting accessibility. To address this, we developed a novel granular hydrogel platform using purely ionically crosslinked alginate and gelatin. By exploiting gelatin's inherent RGD motifs for cell integrin binding, we engineered microbeads of varying alginate-gelatin ratios to assess their influence on HEK 293T cell viability, adhesion, and morphology. These 3D granular matrices were compared to 2D hydrogels of identical compositions to evaluate substrate surface effects on cells. This simple, chemical-free gelation method significantly enhances the accessibility of complex 3D tissue engineering models.

Surgical site infections (SSIs) account for 20% of hospital-acquired infections, increasing patients’ risk of disability and mortality and raising costs for hospitals. This quality improvement project, using the Model for Evidence-Based Practice Change, aims to reduce SSIs at a rural hospital by 20% within one year. Engaging key players, proven strategies will be implemented, including preoperative nasal decolonization, reducing operating room traffic, and using an SSI risk tool. These strategies will be evaluated through electronic medical record (EMR) documentation audits, tracking door openings, nasal swab cultures, and surveys assessing the SSI risk tool’s impact on clinical decision-making.
Ensuring Safe Soil for Indigenous Food Sovereignty: Contaminant Screening for Agroecological Health

Indigenous food sovereignty is a foundational component of human and environmental health.
The Rou Dalagurr Food Sovereignty Lab and Traditional Ecological Knowledges Institute at Cal Poly Humboldt (FSL) foregrounds Indigenous-led approaches to land management and oversees several sites adjacent to campus infrastructure. To ensure that food and basketry materials cultivated at the FSL do not pose a risk to human health, soil samples were collected and screened for contaminants. Heavy metals, phthalate esters, and hydrocarbons were not detected at levels that would affect human health or FSL objectives. This work demonstrates how community-engaged research can inform safe land stewardship while supporting Indigenous sovereignty and continued cultivation of culturally significant foods and medicines.

During my College Corps fellowship at Silvercrest HUD housing, I supported low-income seniors and disabled residents as they navigated complex social systems in a rural setting. I provided case management by connecting individuals to vital resources, simplifying documentation, and advocating for accessible medical transit. This work is critical because it builds self-advocacy skills and mitigates the severe isolation associated with rural poverty. This experience bridged my academic theory with real-world practice, synthesizing my BSW education into applied clinical skills as I advance toward my MSW and ultimate LCSW licensure.

Evaluation of a Novel Trap Design for Anurans in Genus Hylia
Presentation Year:2026
Francisco
Valdez,
Undergraduate Student,
Wildlife
This project tested the Acoustic Adaptation Hypothesis (AAH) in Pacific tree frogs (Pseudacris regilla) as it relates to shelter selection in the Arcata Marsh using a novel trap design. AAH posits that animal vocalizations evolve in response to the acoustics of the surrounding environment, selecting for vocalizations that travel the farther with less distortion. This project evaluates the strengths and shortcomings of the novel trap design in order to further improve future studies in anuran shelter selection and the AAH.
Evaluation of Novel Cellulases
Presentation Year:2026
Layla
Beck ,
Undergraduate Student,
Chemistry
In partnership with the Joint Genome Institute, genetic sequences from the rumen of the cow that encode potential cellulase enzymes were acquired in the form of engineered plasmids which were transformed into E.coli and overexpressed to produce large amounts of protein. This protein was then purified and tested for cellulose-degrading capability. The ability to enzymatically degrade cellulose into glucose as efficiently as possible is relevant to the biofuel industry, since cellulose in agricultural waste can be utilized to create bioethanol rather than the food crops currently used.

Robert
Broadway,
Undergraduate Student,
College Corp
Development of a martial arts Manual for K-12 students, designed tailored to meet the needs of both adapted physical education and general education populations. After 20 years of experience instructing children in Kung Fu, I have consistently observed its profound and engaging impact on young learners. Kung Fu has an unrivaled ability to motivate children to exercise. My goal is to establish a martial arts curriculum within educational institutions that ensures inclusivity and accessibility for all children, including those with disabilities. Following my research into the requirements of this type of program, I believe that providing a martial arts manual offers the most effective path to achieving accessibility and inclusion. The manual will help the martial arts program by offering step-by-step instructions that can be adapted to meet individual needs. The manuals cover will be designed to look like a traditional martial arts manual while the inside resembles a colorful children’s book. The success of a martial arts program in Humboldt County could set an example for all of California. Many children will have access to a quality physical educational program for their mental and physical well-being.

Exploring Cellular Communication Network Factor 3 for Craniofacial Bone Regeneration
Presentation Year:2026
Priscilla
Gamez,
Graduate Student,
Biological Sciences
Skeletal stem cells (SSCs) are multipotent cells that generate bone, cartilage, and stromal lineages essential for skeletal repair. CCN3 is a bone-anabolic factor that promotes osteogenesis, but its effects on craniofacial SSCs remain unclear. This study uses flow cytometry to characterize SSC populations in mouse mandible versus long bone, revealing site specific differences in bone cartilage stromal progenitors and other subpopulations. Mandible derived SSCs and MSCs will be isolated, expanded, and treated with CCN3 during osteogenic differentiation. Mineralization will be assessed using Alizarin Red S staining to evaluate osteogenic activity. These findings will provide new insight into the unique biology and therapeutic potential of SSCs within the mandible.
