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 Margaret Lang Environmental Resources Engineering Dr. Margaret Lang received funding from the National Park Service to assess the condition of culverts (tunnel structures under roadways that provide cross drainage) throughout Redwood National Park. Many of the park’s culverts have not been properly assessed in over 40 years, and may be acting as passage barriers to federally threatened coho and chinook salmon, and steelhead trout. The project will provide the park with site survey data and a culvert replacement priority list, contributing to the preservation and enhancement of the park’s natural and cultural resources. Cal Poly Humboldt students will assist in conducting the assessments.

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.

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.

Faculty Brian Tissot, Sean Craig Biological Sciences Drs. Brian Tissot and Sean Craig received funding to continue ongoing monitoring research in Marine Protected Areas (MPAs) along the California coastline. MPAs are regions designated and managed for the long-term conservation of marine resources, ecosystems services, or cultural heritage. Specifically, he and his team are looking at underwater kelp forests, collecting ecological and environmental data that will inform the evaluation and adaptive management of California’s network of MPAs. The project includes collaborators from UC Santa Cruz, UC Santa Barbara, and Occidental College. Funding comes as a subaward from UC Santa Cruz, with the primary funder being California Sea Grant.

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 Erik S. Jules Biological Sciences Erik Jules (Biological Sciences) published a paper with ten Humboldt student co-authors in the American Journal of Botany (doi.org/10.1002/ajb2.16112). The study -- titled "Genotype accounts for intraspecific variation in the timing and duration of life cycle events" -- was an experimental study of willows covering an area approximately the size of a football field. The results showed that the timing of key life events, such as leaf emergence, flowering, and fruit set, are all heritable traits, indicating that natural selection could favor some individuals under changing climate conditions. Of the ten students, six went onto graduate school after leaving Humboldt.

Faculty William Wood Chemistry Emeritus Chemistry Professor William Wood recently published an article in the Austrian Academy of Sciences journal Biosystematics and Ecology on the oyster-like odor of the plant, Mertensia maritima.  This plant has a circumboreal oceanic distribution where it grows just above the high-tide mark, most often on exposed maritime shingle bars. Because of the smell of crushed plant leaves, it is called the oyster plant in Britain and Ireland, and oyster leaf in North America. Wood collected this plant in Homer, Alaska and is the first person to identify the chemical that gives this plant its common names.

Faculty Diksha Shrestha, Jun Ou, Ariel Rogers, Amani Jereb, Deborah Okyere, Jingyi Chen, Yong Wang Environmental Resources Engineering In collaboration with University of Arkansas, we recently published a journal paper at Colloids and Surfaces B: Biointerfaces. In this work, we mimicked soil-like porous media by microspheres at various densitiesm, simultaneously characterized the pores and tracked bacterial motion in pores, quantified changes in bacterial swimming due to pore-scale confinement, established correlation between bacterial trapping and geometric confinement, and proposed the importance of distinguishing bacterial motility from mobility.

Faculty Frank Fogarty Wildlife Dr. Frank Fogarty received funding to study how retained patches of trees in timber harvests effect bird communities in managed forests of the Pacific Northwest. Regulations in Oregon and Washington prescribe a minimum number of standing trees that must be retained by timber harvest operations, in part to enhance the biodiversity value of harvested lands. Dr. Fogarty will work with a graduate student to experimentally compare a variety of spatial retention arrangements, with the goal of demonstrating which retention strategies maximize avian diversity post-harvest. Funding comes from the National Council for Air and Stream Improvement.
