Staff Allyson Carroll Forestry, Fire & Rangeland Management Allyson Carroll (research associate) received a grant from the United States Geological Survey (USGS) to support research that will use redwood tree rings to date earthquakes on the northern San Andreas Fault. Tree ring signals, such as changes in growth and dates of reiterated trunks, will be used to constrain the year of the large magnitude event that occurred prior to the 1906 earthquake. Project findings will improve earthquake recurrence models for this region. Collaborators include Dr. Stephen Sillett and Marie Antoine at Cal Poly Humboldt, as well as Dr. Belle Philibosian at USGS and Dr. Ozgur Kozaci.

Faculty Prof. C.D. Hoyle Physics & Astronomy Dr. C.D. Hoyle is a co-author of a new publication that discusses the results of a 15-year campaign to map the moon’s orbit at the millimeter level. Such measurements can be used to test the validity of General Relativity and test theories that predict new physics. https://doi.org/10.1088/1538-3873/aceb2f

Faculty Justin Luong Forestry, Fire & Rangeland Management Dr. Justin Luong received a $520,000 grant to study how managed cattle grazing can provide benefits for wetland plant and animal communities at the Willits Bypass in Mendocino County. Managed grazing is a powerful tool for land management and has the potential to bolster biodiversity and carbon storage. Dr. Luong will work with local land agencies to assess how grazing exclusion affects special status plant species, overall plant communities, biodiversity, and soil carbon storage through traditional field study methods and aerial imagery. Collaborators include Drs. Sharon Kahara and Buddhika Madurapperuma. Funding comes from the California Bountiful 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 Hunter Harrill Forestry, Fire & Rangeland Management Dr. Hunter Harrill (Forestry) was invited to give a presentation titled "Grapple Yarding Productivity Studies."

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. https://doi.org/10.1093/jhered/esad018

Faculty Dr. Peter Goetz, Dr. Andrew Conner Mathematics Published a paper titled: QUANTUM PROJECTIVE PLANES AS CERTAIN GRADED TWISTED TENSOR PRODUCTS  in The Journal of Algebra; https://doi.org/10.1016/j.jalgebra.2022.11.033. The paper is joint with Dr. Andrew Conner at Saint Mary's College of California and will appear in the April 2023 issue. The main results of the paper are: (1) a classification up to algebra isomorphism of quadratic graded twisted tensor products of K[x,y] and K[z], and (2) the determination of which three-dimensional Sklyanin algebras contain a quantum P^1. Sklyanin algebras first arose in the late 20th century in the context of quantum inverse scattering problems in physics.

Faculty Meenal Rana, Beth Phelps, Lonny Grafman Environmental Resources Engineering Meenal Rana, with co-authors, Beth Phelps and Lonny Grafman, has received the SSSP Best Paper Award in Social Entrepreneurship and Innovation for the paper, “Youth-Adult Partnership in Social Entrepreneurship and Community Engagement: A Case Study of Daula Village in India.” at the Society's annual conference in Philadelphia (Aug 18-20). The works adds to the literature by demonstrating ways the youth-adult partnerships can benefit the communities in their social entrepreneurship goals. The data comes from the "Rural Youth Volunteers in India", an international experiential learning project, in which Humboldt and Indian students and faculty worked for 11-weeks in two rural communities. 

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.

Faculty Susan Edinger Marshall Forestry, Fire & Rangeland Management Dr. Susan Edinger Marshall received a planning grant from the USDA National Institute of Food and Agriculture (NIFA) to develop the California Rangeland Education (CRED) program in collaboration with Cal Poly San Luis Obispo, UC Berkeley, UC Davis, and Audubon California. The initiative aims to assist individuals in completing educational requirements to sit for the California Certified Rangeland Manager (CRM) exam, analogous to the Registered Professional Foresters (RPF) exam. The program will create a curated study guide for prospective candidates, and also inventory and suggest integrative range courses being offered in California, perhaps by collaborating with other campuses and ranches.

Faculty Justin Luong and Kerry Byrne Forestry, Fire & Rangeland Management Drs Justin Luong and Kerry Byrne received a $1.4 million UC Climate Action Grant for several projects supporting climate resiliency in California grasslands and rangelands. Grasslands serve as the foundation for California’s ranching economy, and support ecosystem services like carbon and water storage, flood mitigation, and ecotourism. In light of climate change, innovating ecological restoration that focuses on climate resilience is imperative. Luong and collaborators (CSU-Chico, CalPoly-SLO and PointBlue) will work with land managers across California to establish a Grassland Restoration Action, Science and Stewardship (GRASS) network for coordination and resource sharing, and developing climate-resilient grassland restoration protocols.
