Habitat Selection of American Crows in Eureka, CA

Christina Parra, Wildlife Undergraduate Student

College of Natural Resources & Sciences

I looked at habitat selection of crows within the city of Eureka. I conducted point count surveys to compare the number of crows within residential/commercial areas (urban) and park areas to see which habitat type crows prefer.

Harmonic Analysis of Currents in Humboldt Bay

Steven Gracy, Physics & Astronomy Undergraduate Student

College of Natural Resources & Sciences

Currents can shape the structure and ecology of estuarine environments. Multiyear time series of current data measured by two Acoustic Doppler Current Profilers (ADCPs) in Humboldt Bay, CA, one near the entrance channel and one at the Chevron Port, were analyzed to determine the contributions of the different harmonic frequencies. Spectral analysis of the time series data revealed that the flow is dominated by several tidal harmonics. The three dominant frequencies include M2, K1, and O1, but their contribution varies spatially between the two stations. Additional frequencies in the data indicate interference with topography as well as the more variable wind-induced currents.

Harmonic Analysis of Currents in Humboldt Bay

Taylor Juchau, Physics & Astronomy Undergraduate Student

College of Natural Resources & Sciences

Multiyear time series of current data measured by two horizontal SonTek/YSI Acoustic Doppler Current Profilers (ADCPs) placed mid-depth in the water column (~4.8m depth) at two locations in Humboldt Bay, CA, a shallow, tidally-driven estuary in northern California (USA), were analyzed to determine the contributions of the different harmonic frequencies within the bay. Spectral analysis of the time series revealed that the currents are dominated by several tidal harmonics. The three dominant frequencies include M2, K1, and O1, but their contribution varies spatially between the two station locations. Additional frequencies in the data indicate overtides and variable influences like wind.

This is my senior project about how ankle braces or taping affects mobility in multidirectional sports.

How Shoelace Conditions Impact Foot Ergonomics

Eon Ebuna, School of Applied Health Undergraduate Student

College of Professional Studies

Various lacing methods have been employed to enhance running performance and mitigate the risk of injuries. Runners have experimented with these patterns to identify the optimal configuration for their running form, anatomy, and sport. This research emphasizes the pivotal role of shoelace techniques in the broader context of ergonomics and injury prevention, highlighting the relationship between how the foot is laced within the shoe and its implications for the overall well-being of the runner. Tight laces with additional contact points adhere the foot to the shoe best but must also leave enough room in the shoe for the runner’s anatomy to perform natural anatomical mechanisms such as receiv

Human Disturbance and Anthropogenic Noise Impacts on Foraging Egrets at the Arcata Marsh

Yesenia Cerrillo, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Human disturbance and assessing the effects of humans recreational activities and anthropogenic noise on foraging opportunities of migratory and non-migratory shorebirds needs to be studied further. This study aims at determining how foraging in 2 species of egrets found in Humboldt County in a human used recreational area are impacted.

Human Impacts on Songbird Abundance and Diversity

Chloe Good, Wildlife Undergraduate Student

College of Natural Resources & Sciences

My study investigates how human disturbances affect songbird diversity and abundance in Arcata, CA. Many songbirds try to adjust their behavior in response to human populated environments; however, adjustments can have intense effects on their survival, and serious ramifications beyond urban settings (Marzluff 1997). My findings aim to better inform conservation efforts of species specific requirements and minimize areas with human disturbances as needed.

Humboldt County Population Growth Correlated to Unidentified Flying Object Reports 1920 - 2021

Starsong Brittain, History Undergraduate Student

College of Arts, Humanities & Social Sciences

This project looked to see what correlations could be found here in Humboldt county between population changes and annual number of Unidentified Flying Objects (UFO) repots from the years of 1920 to 2021.

Humboldt Forensics: Lumberjack Speech and Debate 1926 - 2023

Aaron Donaldson, Communication Faculty

College of Arts, Humanities & Social Sciences

A summary of Intercollegiate Forensics at Humboldt from the founding of the program in 1926 to cancellation in 2023.

Hummingbird Nectar Preference in Urban and Forested Areas

Bridget Blanco, Wildlife Undergraduate Student

College of Natural Resources & Sciences

My study investigated the nectar preference of Anna’s hummingbirds and whether foraging increased as the temperature increased from winter to spring. The results of this study will aid in determining the best plants to maintain and restore in natural areas in order to maintain a healthy environment. By providing the best nectar solution, we can contribute to maintaining robust hummingbird populations.
