Congratulations to Belle Burnside (BS Ecology, 2025), who earned Top Poster Presentation honors in the Ecology, Evolution and Biodiversity category at the annual Murdock College Science Research Conference. Belle's presentation, "Succession and forest maturation decreases population density of black-tailed deer on Blakely Island, WA", was mentored by Dr. Eric Long, Professor of Biology. Belle was one of 14 students from the Biology and Chemistry & Biochemistry departments who presented their research at the conference, which was attended by over 300 students from universities around the Pacific Northwest. More information on SPU's student presenters is available on the Biology department website.
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.
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.
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.
