Due to the many industrial processes of modern America, heavy metal contamination of our waterways, specifically in densely populated areas, has become a major issue. The Prokaryotic species Caulobacter vibrioides exhibits a surface layer protein, RsaA, forming a 2-D crystallin array above the cell membrane. RsaA can be modified to exhibit a high binding potential with many of the charged ions, such as heavy metals, which are found in waterways. Here we show through an quantitative fluorescence assay that upon exposure to 39.063nM Pb solution, engineered C. vibrioides strains Hcm 027, and 028 remediated approximately 10% more Pb than the wildtype, Hcm 009.
Narrative Mapping of Genocide: A Transformative Approach in Reader’s Advisory
- Amanda AlsterAnthropologyUndergraduate Student
Studies show that knowledge of atrocities in history such as the Holocaust is rapidly declining. Fewer people are searching these topics or reading related articles, and evidence shows there is a significant decline in the reading of literature altogether. To address these issues on a small scale, I created an interactive digital platform using geographic locations to share the various literary narratives of those who have experienced genocide first hand. I examined the impact of transformative approaches, such as GIS software, to provide a new method that actively engages and directs readers to books from a geographic perspective.
Native Alaskans and Wildlife Interactions and Issues
- Barbara Larrondo-SotoNative American StudiesUndergraduate Student
This project encompasses the relationship and issues connected to Alaskan Natives and wildlife. Their relationship to the land and wildlife is deeply rooted in their history, and most Alaska natives practice traditional hunting and gathering practices. Native Alaskan interactions with the natural world is interwoven in the way in which they define subsistence, which is synonymous with culture, identity, and self-determination and involves conservation and perpetuation of natural resources. The US Federal and Alaska State government define subsistence differently and have passed Acts and policies that interfere with the Native’s aboriginal hunting and fishing rights.
Native American Schools
- Amy TorresCommunicationUndergraduate Student
The focus on my project will be in education in Native American schools. I will research about the structure of the schools such as Albuquerque Indian School, Chemawa Indian School and Carlisle Indian School and then talk about what happened in the past and forward each of the schools. Reason(s) why the topic being researched: The reason why I am planning to do research on education in Native American schools is because my family is mixed racially and I want to learn more about what occurred at the following Native American schools.
Native American Storytelling
- Olivia KakacekZoologyUndergraduate Student
- Bryan FosterZoologyUndergraduate Student
- Abigail WesendunkZoologyUndergraduate Student
We are focusing our topic on the role that animals have in Native American storytelling, and how these animal's behaviors in real life are reflected in the stories. Storytelling is a way of communication that Natives use to share knowledge between generations; often, these stories use animals as symbolism. Our group is composed of all zoology majors interested in studying animal behavior, and we will compare the personality traits and characteristics of these animals to their role played in these stories.
Natural History and Basking Habits of Western Pond Turtles
- Gaby RusoWildlife BiologyUndergraduate Student
This research represents the preliminary results of a longer term project in Sequoia National Park, California. I used temperature dataloggers to investigate western pond turtle behavior to better understand their natural history and thus inform monitoring protocol and conservation. These data suggest that snorkel surveys used to monitor turtle populations may be more effective if conducted at night. In addition, these data indicate the potential for intraspecific niche partitioning among turtles according to age. These early results hint at unique turtle behavior that is otherwise difficult to observe for a cryptic species and thereby warrant further investigation.
Natural Influences from Inside and Outside of the Classroom
- Amanda HenmanChild DevelopmentUndergraduate Student
The research project has been developed to investigate what the relationship is between early education students, teachers, living plants inside and outside the classroom, and the environment outside the windows. The research project surveys 32 center-based programs among rural and urban early education programs to produce quantitative and qualitative data for a research project that will support a blog site. The blog site will include curriculum plans, activities and images supporting incorporation of plants in children’s environments and children’s interactions with natural materials and playscapes.
NCAA DoD Grand Alliance: Concussion Assessment, Research and Education (CARE) Consortium – Longitudinal Clinical Study Core

Humboldt State University received a two-year grant from the NCAA and the U.S. Department of Defense to expand upon the existing study that investigates concussive and repetitive head impacts in NCAA student-athletes. This collaboration is to further understand the neurobiopsychosocial nature of concussive injury and recovery to enhance the safety and health of our collegiate student-athletes, service members, youth sports participants and the broader public. At Humboldt State, researchers have conducted baseline and post injury monitoring of neurocognitive, motor control, and behavioral data in 638 athletes from all sports. The poster will have current results from the CARE consortium.
NDCI Analysis and Change Detection for Coral Reef Habitats of Duncan Island In South Chinese Sea from 2016 to 2018
- Christopher LanzEnvironmental Science and ManagementUndergraduate Student
- Buddhika MadurapperumaEnvironmental Science and ManagementFaculty
Mismanagement of coral reef habitats for construction has impacted on rapid destruction of most biodiverse coral reefs of South Chinese sea. This project examines how coral reef habitats changed in Duncan island of South Chinese sea using object based image analysis (OBIA) and coral index. We estimated the coral changes over time with different land-use classes. The unchanged coral acreage was 7.80 acres between 2016-2017, 1.21 acres between 2017-2018 and 8.22 acres between 2016-2018. The coefficient of agreement for the classification is ranged from 0.55 to 0.60. NDCI Analysis of coral regions surrounding Duncan island revealed vegetation change in coral health.
Needs Assessment for Resource Compilation for Persons Experiencing Homelessness While Caring for a Companion Animal
- Sophia Gang-HalvorsonSocial WorkGraduate Student
Individuals facing poverty and homelessness can be denied housing when care-taking for a companion animal. Sometimes a refusal of housing is caused by rules which prohibit companion animals in housing, so the preference is to remain homeless. My project provides a compilation of local, free, and low cost resources to help provide for the companion animal’s care. A needs assessment with persons facing long-term homelessness informed the list. The compilation will allow a person facing poverty to make informed choices among resources in the community that would facilitate a healthy human-companion animal relationship regardless of status of homelessness.
