Lynnwood Auditorium (unless otherwise stated)
Presented by the Kappa Phi Chapter of the Tri-Beta National Biological Honor Society and the Biology Department
The E.O. Grundset Lecture Series, named in honor of Southern’s beloved biology professor of 35 years, hosts research presentations by biologists and other scholars.
Scheduled Lectures—Fall 2019
"Faith and Science: My Journey from Childhood to a Career in Science."
Penelope Deurksen-Hughes, PhD, Loma Linda School of Medicine, Loma Linda University, California.
September 5—7:30 p.m., Lynn Wood Hall Auditorium
In this presentation, Dr. Deurksen-Hughes will recount how her understanding regarding the connections between her faith and her passion for science has changed from her early childhood into a career as a professional cancer researcher.
"A Sting to Die For: Venom Composition and Venom Expenditure in Scorpions." (RS-Research)
Bill Hayes, PhD, Earth and Biological Sciences, Loma Linda University, Loma Linda, California.
September 19—7:30 p.m., Lynn Wood Hall Auditorium
Venomous animals often possess complex venom delivery systems that are designed to inject their toxic secretion into the tissue of prey and/or predators. Effectiveness of venom deployment depends on two critical factors: composition and quantity of venom delivered. To better understand the venoms of scorpions and how it is used, we conducted a series of behavioral and chemical studies to investigate the venoms of two North American species (the desert hairy and the dune scorpions) and one African species (the South African fattail scorpion). Venom is a complicated secretion and we have observed its' use to be more sophisticated and varied than previously thought.
"When you can't run and you can't hide: sea urchins under near-future ocean conditions." (RS-Research)
Cecelia Brothers, PhD, Department of Biological Sciences, Walla Walla University, Walla Walla, WA.
Climate-induced changes to global ocean temperatures and pH are occurring rapidly. One serious concern is the effect of increased and acidification on organismal stress levels, especially when the affected species are ecosystem engineers such as sea urchins. I conducted experiments on three species of sea urchins from different geographic regions (the Gulf of Mexico, Australia, and Antarctica) that are disproportionately experiencing the effects of climate change. I found that sea urchins exposed to near-future ocean conditions had different digestive system microorgansims, less efficient immune systems, and altered their behavior. These results demonstrate the varied effects, both direct and indirect, that climate change may have on sea urchin populations around the world.
"Whale Sharks, Mantas and Jellies: Oh My! From Happy Valley to a Career in Public Aquaria." (CB-Careers in Biology)
October 24—8:00 p.m., Lynn Wood Hall Auditorium
You know what you love, but can you make a living at it? When your dream is to have a job where you can swim with sharks every day, not only do people think you're crazy, but you too recognize the impracticality of such an aspiration. But, life sometimes plays out unexpectedly and dreams can suddenly become reality. In my 20+ years working in public aquaria, I've logged over 750 dives (most with sharks), opened the world's largest aquarium, conducted the first physicals on whale sharks, participated in coral restoration, discovered a new species of box jellyfish, and am currently collaborating with the Smithsonian and National Geographic. This presentation will revisit some of my journey's highlights and the lessons I've learned along the way.
