Faculty Micaela Szykman Gunther Wildlife Dr. Micaela Szykman Gunther received funding from CalTrans to assess the efficacy and statewide applicability of an electronic elk detection system along a section of Highway 101. The system is designed to detect elk and activate warning signs to increase driver awareness when elk may be on or near the highway. Dr. Szykman Gunther will work with both students and the California Department of Fish and Wildlife, who will collar target elk, to monitor elk movement and survival. If successful, this system would increase elk movement between fragmented habitats, increase habitat permeability and survivorship, and decrease risks to passing motorists.

Faculty Rosemary Sherriff, Lucy Kerhoulas and Kerry Byrne Drs. Rosemary Sherriff, Lucy Kerhoulas and Kerry Byrne received a grant from PG&E to study tree health, vegetation, and fuel characteristics in five dominant forest types throughout five counties in Northern California. Research findings will identify conditions that are commonly associated with tree mortality and breakage, which will help PG&E prioritize vegetation management efforts to vulnerable areas. Sara Hanna (Forestry) is also a key collaborator for GIS analysis, as well as two graduate and five undergraduate students.

Student Jacob Aguilera, Elizabeth Aparicio, Lisa Elconin, Dennis Lindelof, Jane Martinez, Emily Shiver, Jacky Baughman, Melanie Michalak Geology Jacob Aguilera, Elizabeth Aparicio, Lisa Elconin, Dennis Lindelof, Jane Martinez, and Emily Shiver presented their original research in Reno, NV at the Geological Society of America Section Meeting. They participated in a pilot one-year long program integrating quantitative, field and lab-based geologic research into the Geology curriculum, led by faculty mentors Jacky Baughman and Melanie Michalak, funded by an NSF AGeS-DiG grant. They presented two posters; i) on their investigation of the effects of a 52 million year old tectonic plate shift on the northern Klamath Mountains, and ii) what the research cohort collaboration was like from their experience.

Student Daniel Abel, Osvaldo Bustos-Perez, Derek Cohen, Regina Khoury, Jane Martinez, Rebecca Reibel, Giorgio Vitti, Melanie Michalak Geology Daniel Abel, Osvaldo Bustos-Perez, Derek Cohen, Regina Khoury, Jane Martinez, Rebecca Reibel, and Giorgio Vitti co-authored and presented their original research in Reno, NV on May 17th at the Geological Society of American Cordilleran Section Meeting. Their research used statistical approaches from geochemical data to reconstruct the geologic and tectonic history of the Montgomery Creek Formation, an ancient river system that is found today in the eastern Klamath Mountains Province. The original work was incorporated into a Methods in Geochronology course taught by Melanie Michalak (Geology); students travel was supported by the Geology Moory Opportunities Fund.

Faculty Dr. Jose Marin Jarrin, Dr. Andrew Kinziger, and Michelle Schuiteman Fisheries Biology Dr. Jose Marin Jarrin, Michelle Schuiteman, and Dr. Andrew Kinziger received a grant to develop a population baseline of fish communities in the lower estuary of the Klamath River. The study will ensure that changes in the Klamath River estuary due to climate change and dam removal will be measurable, and will also develop a working group that can continue to tackle coastal marine issues in Northern California, including Klamath estuary monitoring. The project will be led by the Yurok Tribe Fisheries Department, with support from the California Department of Fish and Wildlife, and US Fish and Wildlife Service staff.

Student Abby Keltz, Alexandra Papesh Physics & Astronomy Physics & Astronomy majors Abby Keltz and Alexandra Papesh presented research at the 2023 April Meeting of the American Physical Society (APS), held in Minneapolis, MN from April 15th - 18th. Keltz presented the talk "Testing Gravitational Interactions Below 50 Microns," while Papesh presented a poster describing a collaborative project with Indiana University-Purdue University of Indianapolis (IUPUI) entitled "Improved Measurement of the Newtonian Gravitational Constant G." Keltz was recognized as one of the "Outstanding Undergraduate Presenters" by the conference organizers. Both projects are supported by the National Science Foundation.

Faculty Dr Peter Goetz Mathematics Will give a talk titled "Frobenius extensions, Artin-Schelter regular algebras and Azumaya loci" at the Spring Western Sectional Meeting of the American Mathematical Society at CSU, Fresno on Sunday, May 7, 2023. The Azumaya locus of a polynomial identity algebra is an algebraic variety that parametrizes the irreducible modules of maximal dimension. Typically the Azumaya locus is very hard to determine. Dr. Goetz will describe results from his current research project on using Frobenius extensions to compute Azumaya loci.

Faculty Dr. Oscar Vargas Biological Sciences Dr. Oscar Vargas collaborated in the assemblage and annotation of a spiral ginger genome. Authors sequenced the nuclear genome of two species of plants in the family Costaceae. The study provides a draft annotation for the genome by mapping the transcriptome (RNA, expressed DNA) of one species to its draft genome. This study provides useful genetic resources for the study of non-model organisms.

Faculty Lucy Kerhoulas, Erin Kelly Forestry, Fire & Rangeland Management Drs. Lucy Kerhoulas and Erin Kelly were awarded a $299,000 grant to support the ongoing Redwoods Rising student apprenticeship program. The program places students within resource teams to perform seasonal tasks associated with restoration activities throughout the Redwood National and State Parks, where they develop field experience, network with resource management specialists, and contribute to ongoing land management efforts. This summer they hired 12 apprentices to work on projects related to forestry, roads, watersheds, and outreach and interpretation.This project is in collaboration with Redwood National and State Parks and the Save the Redwoods League, which also provides funding.

Student Regina Khoury Geology Regina Khoury has been selected to receive the Alistair and Judith McCrone Graduate Fellowship Award for the 2023-2024 academic year. This fellowship is given to one graduate student each year at Cal Poly Humboldt who demonstrates exceptional academic merit and significant potential for contribution to their field. Regina's MS thesis project with Professor Brandon Browne combines geologic mapping with geochemical and mineralogical analyses of lavas erupted from eight different vents within a ~200 year "flare up" of Medicine Lake volcano in the California Cascades. Her findings will advance hazard mitigation efforts at volcanoes worldwide. Congratulations Regina!

Faculty Erin Kelly, Benjamin Graham, and Jeff Kane Forestry, Fire & Rangeland Management Drs. Erin Kelly, Benjamin Graham, and Jeff Kane received a grant from the Joint Fire Science Program (administered by the Departments of Interior and Agriculture) to support a study on community recovery after wildfires, and how recovery can lead to social-ecological resilience. The study will look into what recovery looks like in communities impacted by wildfires, the networks within communities present for recovery, and the resources available to implement community recovery. Findings will be useful for policy makers trying to create funding, regulatory, and other policy mechanisms to facilitate community recovery, and organizations working toward social-ecological resilience in fire-prone landscapes.

Faculty Silvia Pavan Biological Sciences Dr. Silvia Pavan received a grant from the National Science Foundation to implement a project that will digitize and georeference Cal Poly Humboldt’s mammal collection. The project will be part of a collaborative effort under the Ranges Thematic Collections Network (Ranges TCN), an initiative lead by the University of North Carolina, to digitize and mobilize trait data from mammalian museum specimens from across the American West, including standard external morphological measurements, reproductive and life history observations, and information on ecological associations. Resulting trait datasets will support next-generation anatomical and evolutionary research, and provide baselines for future population monitoring efforts.
