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. Oscar Vargas Biological Sciences Dr. Oscar Vargas collaborated in the description of a new species of spiral gingers from the mountains of Costa Rica. The paper examines the possible causes of speciation by comparing the genetics and climate preference of the new species to its closest relative. https://doi.org/10.1600/036364423X16758877666039 

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 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 Pedro Peloso Biological Sciences Research Associate Dr. Pedro Peloso and collaborators have discovered and described a new species of frog from South America (Brazil and French Guiana). They revealed this discovery in a paper titled "A new Chiasmocleis (Anura: Microhylidae) from the eastern Guiana Shield with an amended definition of C. haddadi", published in the Journal Zootaxa.

Faculty Dr. Oscar M. Vargas-Hernandez Biological Sciences Assistant Professor Dr. Oscar Vargas and collaborators published a paper titled "Evolutionary history constrains heat tolerance of native and exotic tropical Zingiberales." The paper studies the thermal tolerance of native and wild gingers in Costa Rica, discussing its implications to conservation and the biology of invasive species. 

Faculty Pedro Peloso and Brandice Guerra Biological Sciences Dr. Pedro Peloso and Brandice Guerra, M.F.A., received a $10,000 grant from the Maxwell/Hanrahan Foundation to support a scientific illustration residency program at Cal Poly Humboldt. The program will recruit a student or recent graduate from anywhere in the world to work with faculty from the departments of Art+Film and Biology. The intern will create a series of illustrations of recently extinct Brazilian frogs, and share their work and artistic process through a lecture or exhibition on campus.

Staff Matthew D Johnson, Amy Sprowles, Steven Margel, Kat Goldenberg, Raven Palomera Biological Sciences Matt Johnson, Amy Sprowles, Steven Margell, Kat Goldenberg, and Raven Palomera recently published a paper entitled, “Impact of a first‑year place‑based learning community on STEM students’ academic achievement in their second, third, and fourth years” in the journal Innovative Higher Education. The paper reports the effects of the first three cohorts of the Klamath Connection PBLC made possible by contributions from all across the university and funding from the campus’s HSI STEM grant from the US Dept of Education. 

Student Melody Tew, Nicole Rahman-Garnier, Jordyn Neal Biological Sciences Several Cal Poly Humboldt students were recognized at the annual conference for the American Society of Ichthyologists & Herpetologists.

Biology Graduate Student Melody Tew received the Raney and Hubbs awards and presented her research on the developmental origins of White Sturgeon scales.

Biology Graduate Student Nicole Rahman-Garnier received the Cashner and Raney awards and presented her research on the olfactory (scent-sensing) anatomy of local Rainbow Trout.

Recent Marine Biology graduate Jordyn Neal received the Clark Hubbs award and presented her research on the comparative anatomy of the skulls and inner ears of sharks, using high-resolution CT scanning.

Student Club Hannah Cornwell (the PreMed Society student President) Biological Sciences PreMed and PreVet Society students organized an event called Intro To Suturing Workshop on April 25. They invited Dr. Bret Gorham from Providence St. Joseph Hospital and Dr. Ellie Carrier from North Coast Veterinary Hospital. The workshop lasted 2 hours long (much longer than the scheduled one hour) and provided hands-on training to ~25 students on suturing skills. The workshop encourages interest in pursuing healthcare careers.

Faculty Roxann Schroeder Biological Sciences

Roxann Schroeder, lecturer in Biology and ESM, has written an online textbook, Human Genetics: Understanding How Genes Work, to support students in the Human Genetics class.

Student Frank Shaughnessy, Susannah Ferson, Adam Frimodig, Daniel Barton, Mathew Hurst, Jeffrey Black Biological Sciences

Students and faculty from several departments have been studying the effects that grazing by brant geese have on a widespread marine plant, eelgrass, which provides numerous ecosystem services within estuaries. Using an experimental approach, they found that brant enable greater productivity and sexual reproduction of eelgrass, therefore potentially contributing to ecosystem resilience.

Faculty John Reiss and Karen Kiemnec-Tyburczy Biological Sciences

John Reiss and Karen Kiemnec-Tyburczy have been awarded a 3-year National Science Foundation (Division of Integrative Organismal Systems) grant to study the evolution of olfaction across multiple species of lungless salamanders with different developmental modes.

Faculty Catalina Cuellar-Gempeler Biological Sciences

Catalina Cuellar-Gempeler earned the NSF Career award, one of the most prestigious awards offered by NSF.

Student Karley Rojas Biological Sciences

Undergraduate Karley Rojas (Botany) has received a science fellowship from the Agricultural Research Institute for their proposed study of native plants that have the potential to be utilized in the context of agroecosystem building as consistent with regional TEK.
