Scavenging Efficiency in Turkey Vultures (Cathartes aura) at Forested Sites
Ephraim
Lowe
Wildlife
Undergraduate Student
College of Natural Resources & Sciences
Turkey vultures are well known for their incredible sense of smell due to their large olfactory bulbs, which are even larger than some mammals, such as rats. The study conducted compared the olfaction ability of turkey vultures to local mammals in the area by baiting sites in the Arcata Community Forest with carrion. It analyzed which species arrived to carrion sites first, and how weather, temperature, and humidity affected their ability to locate carrion efficiently.
Unraveling the Taxonomic Classification of the Tolowa wallflower (Brassicaceae: Erysimum), a dune endemic of the California North Coast

College of Natural Resources & Sciences
Found in Del Norte County, California, in the Tolowa Dunes State Park, there is an Erysimum population that does not fit the species boundaries of E.concinnum Eastw., its current assigned name. A closely related species, E. menziesi (Hook.) Wettst arguably better fits the morphology of the Tolowa Wallflower, with the caveat that it does not adequately depict the population. Because of the endemicity of the two aforementioned species and the Tolowa wallflower, correct taxonomic assessment and a clear definition of species boundaries are warranted. To evaluate the species boundaries and circumscription of the Tolowa wallflower, we would collect DNA samples from Erysimum found on the coast.
Reclaiming Turtle Island: Decolonizing Anthropological Narratives of Migration
Sadie
Neff
Anthropology
Undergraduate Student
College of Arts, Humanities & Social Sciences
The Western-centric focus on early habitation of Turtle Island (North America) has often disregarded Indigenous oral histories as myths. It is critical to question how migration theories can dismiss Indigenous credibility. This objectification of western science perpetuates oppression of Indigenous peoples and assists in validating settler-colonial narratives. Academia has historically denied, or labeled controversial, North American archaeological sites older than 12,000 years, silencing advocates in the process. My goal is to highlight these injustices and underscore the importance of honoring Indigenous oral histories. I advocate for an inclusive, decolonized approach to archaeology.

My research is on Virtual Reality or "Active Gaming" and how it can indirectly have the potential to reduce Obesity and Heart Disease, by being a leisurely activity with some amount of activity rather than something sedentary.

This study examines media representations of the removal of the Klamath Dam, a development in Northern California's Indigenous land restoration efforts. Recognizing the historical underrepresentation of Indigenous voices in mainstream media, this research analyzes local coverage of the Klamath dam removal project by Humboldt County's leading news organizations: North Coast Journal, Times-Standard, and Lost Coast Outpost.

The Northern California Indian Development Council (NCIDC), founded in 1976, is a nonprofit organization. They are dedicated to serving the needs of Native communities across Northern California, around 15,000 clients annually. Our youth-focused initiative aims to highlight the importance of transportation and accessibility in connecting Native youth to The Nest Youth Center and community events. We strive to improve engagement by offering culturally relevant activities that strengthen identity and connection to one another. By fostering leadership and providing essential tools and resources, we aim to empower Native youth to grow, thrive, and become strong leaders within their communities.
Determining Magma Mixing Duration and Dynamics Through Analysis of Reaction Rims on Olivine Crystals in Natural Samples of Black Dacite From the 1915 Eruption of Lassen Peak, CA
Nathan A. Graham
Department of Geology
Undergraduate Student
College of Natural Resources & Sciences
Disequilibrium reaction rim textures on olivine grains from black dacite from the 1915 eruption of Lassen Peak were measured and coupled with experimental reaction rim growth rates to estimate the duration of magma mixing that took place prior to the 1915 eruption. Reaction rims on 100 olivine grains were measured and the duration of magma mixing prior to the 1915 eruption was estimated to be between 12-17 months. The abundance of reaction rim growth varies during the duration of magma mixing and is evidence that the eruption of Lassen Peak was catalyzed by multiple injections of hot basaltic andesite into a relatively cool and mushy dacitic reservoir magma chamber prior to eruption.
Rebekah Lodge Historical Collection

The goal of this project is to establish an ethnographic archive that documents Humboldt County women's stories and experiences. This archive will contain both historical and contemporary material and be devoted to making the stories, struggles, and achievements of women in Humboldt County known. The Rebekah's Lodge was a Independent Order Of the Oddfellows, whose main goal was to serve the community around Humboldt County through their services and volunteer work.
Island Biogeography: Invasive Species and Eradication Programs
Daniel Cooper
Geography
Undergraduate Student
College of Arts, Humanities & Social Sciences
For this project, a masters list of introduced mammals was provided. The masters list consisted of several different species of mammals who were classified by family, genus, species, and common names. Each species was accompanied by islands they were introduced too. Using the “Database of Island Invasive Species Eradication,” each animal on the list was searched for to see if they were successfully eradicated. If these animals had been eradicated, then the date and method of eradication were recorded. If these species didn’t show up on the database, then they were search for using various different search engines. If animals still remain of these islands the question becomes why?
Screening for Regulators of Quiescence in Drosophila Testis Stem Cell Niche
Linh Pham
Biology
Undergraduate Student
College of Natural Resources & Sciences
Interactions between stem cells and their microenvironment, or niche, are not thoroughly understood. The Drosophila testis stem cell niche provides a simple model to observe niche-stem cell interactions. This niche contains non-dividing hub cells that signal to adjacent germline stem cells and somatic cyst stem cells (CySCs). If the testis is damaged (specifically, if CySCs are eliminated) hub cells sense their absence and respond by dividing and changing their identity (or transdifferentiating), becoming replacement CySCs. Because transdifferentiation occur in many niches and can promote tumor formation, we are using Drosophila testes niche as a model to gain more insights on this process.
