50 SPU students contributed to salmon mislabeling fraud study
Nov 6, 2024
Dr. Tracie Delgado, Professor of Biology, is the senior author of a new study in the peer-reviewed journal PLoS ONE. This study, carried out by 50 students in Dr. Delgado's lab and in her Genetics course, provided genetic evidence that "wild-caught" salmon sold in sushi restaurants and grocery stores were often actually farm-raised salmon. Professors of Biology, Dr. Eric Long and Dr. Tim Nelson, also contributed to this study. This study has been reported on by multiple media outlets, including NPR (KUOW), KING-5, the Seattle Times, Newsweek, ABC news, Popular Science and others. More information about the study is available on the Delgado lab website.

New study from Dr. Wall-Scheffler examines impact of longer lower limbs on running
Oct 30, 2024
Dr. Cara Wall-Scheffler, Professor of Biology, and collaborators at Charles University in the Czech Republic (where Dr. Wall-Scheffler was a Fulbright Fellow), published a new study, "Impact of relative lower-limb length on heat loss and body temperature during running" in the American Journal of Biological Anthropology. This study found that runners with longer lower limbs relative to overall body size experienced greater heat loss and smaller increases in mean body temperature compared to runners with shorter lower limbs relative to overall body size. Surprisingly, this thermoregulation was not due to increased body surface area, as was previously predicted. This study provides further evidence to the adaptive significance of lower limb length in thermoregulation across a variety of physical activities.

The Galapagos Global Seminar is now accepting applications
Oct 3, 2024
In June 2025, Professors of Biology, Dr. Eric Long and Dr. Ryan Ferrer, will lead students on a trip to the Galapagos Island, which has played a pivotal role in our understanding of evolutionary biology. Students can earn credit for either BIO 3303 (Evolutionary Ecology in the Galapagos Islands, 5 Credits) or BIO 3304 (Oceanography of the Galapagos Archipelago, 5 Credits). For more information and to apply, please see the Study Abroad program website. The application deadline is January 13, 2025.

Dr. Cara Wall-Scheffler discusses human evolution in The Conversation article
May 10, 2024
In a new post on the science-focused journalism site, The Conversation, Dr. Cara Wall-Scheffler, Professor of Biology, argues that the activities of everyday life influence human evolution just as much as “uncommon activities” (such as big-game hunting). The article, "Everyday life and its variability influenced human evolution at least as much as rare activities like big-game hunting", draws from Dr. Wall-Scheffler's own research and the research of other scientists to present a new model for understanding how humans evolve in response to their social and environmental interactions.

Dr. Cara Wall-Scheffler named 2023 AAAS Fellow
Apr 19, 2024
Dr. Cara Wall-Scheffler, Professor of Biology, was named to the 2023 AAAS Fellow class in the Section on Anthropology. The AAAS Fellows is a prestigious honor bestowed by the American Association for the Advancement of Science, recognizing top scientists in their fields. It is highly ususual for faculty from non-research-intensive (R1) universities to be recognized. This recognition is a testament to Dr. Wall-Scheffler's transformative research, and demonstrates that high-quality research with undergraduate students is not only possible, but necessary. More information on the AAAS Fellows honor is available here. Congratulations, Dr. Wall-Scheffler!

Biology programs are featured Giving Day 2024 campaigns
Apr 2, 2024
SPU's annual Giving Day will be Wednesday, April 3, 2024, and features two core Biology programs. The BioCORE Scholars Program supports students who are underrepresented in STEM and health care fields by providing academic enrichment, research experience, networking and scholarships. If at least ten donors give to the BioCORE Scholars Program, we will receive an additional $100, thanks to a generous donor. Please donate via the BioCORE Scholars Giving Day page!
Blakely Island Field Station in the San Juan Islands is a beloved site for research and fellowship for both students and faculty. Funds raised will go to restoring aging infrastructure around the field station and to support student research. Please donate via the Blakely Island Giving Day page!
The campaign with the greatest number of donors will receive an additional $1500, with $1000 going to the campaign with the second-highest number of donors. Giving Day is an important source of financial support for our programs, and we greatly appreciate any contributions!

Biology faculty and alumnus publish new deer research study
Feb 27, 2024
Professors of Biology Eric Long and Ryan Ferrer, along with alumnus Enoch Tham (BS Ecology, 2019) co-authored a new research article in PLoS ONE (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0298231). The article, “Succession and climatic stochasticity induce long-term decline of a forest browser”, examined the long-term effects of forest regrowth and maturation on the density of black-tailed deer on Blakely Island. Long, Tham and Ferrer found that as timber harvests decreased and forests matured on Blakely Island, black-tailed deer populations decreased. These results are among the first to quantify deer population declines in response to forest regrowth and increased canopy cover, and have long-term implications for island ecosystem recovery and population survival in response to significant events such as climate change and disease.

Gum Nau presents research at SICB Conference
Jan 1, 2024
Gum Nau (BS Physiology, 2024) will give an oral presentation at the annual Society for Integrative and Comparative Biology (SICB) conference in Seattle on Friday, January 5. His talk, titled "Trophic tinkle: Predator pee fails to frighten foragers and conifer chemistry depends on deer damage", will report work Nau did in collaboration with biology students Hannah McSwain (BS Ecology, 2024) and Kenzie Garrett (BS Physiology, 2024), and supervised by Professors Ryan Ferrer (Biology), Eric Long (Biology) and Baine Craft (Psychology). It is unusual for undergraduates to be selected for oral presentations at a national conference like SICB - congratulations, Gum!

Three Biology students present at the 2023 SACNAS conference
Nov 11, 2023
SPU was represented by three current and former Biology students at the 2023 SACNAS National Diversity in STEM Conference, held October 26 - 28 in Portland, Oregon. Yennifer Gaspar Garcia (BS Physiology 2025) presented her project, "DNA barcoding reveals Salmon mislabeling rates in Seattle sushi restaurants", in collaboration with student Angelique Djekoundade and Dr. Tracie Delgado, Associate Professor of Biology. Krysta Reese (BS Ecology 2024) presented her project, "DNA barcoding of marine and freshwater goby fish, Negros Oriental and Palawan, Philippines", based on research she conducted as part of the Philippines International Research Experience for Students (Ph-IRES) in Summer 2023. Finally, Abhi Kancherla (BS Cellular and Molecular Biology 2023) presented "5-Nitroimidazole-resistance in Mycoplasma genitalium strains is associated with mutations in an NAD(P)H-dependent FMN reductase gene", which was work he did in collaboration with students Alessandro Rizzi and Cameron Weller, and Dr. Derek Wood, Professor of Biology.
