Diving for Discovery

Jon and others looking at the way that light passes through an obsidian artifact

Jon Krier was six-years-old when he found his first skull. He was on a walk with his mother in Wales, Alaska where his father worked as a surveyor. “She immediately told me to put it down,” he said. But he couldn’t shake his fascination: Where did the skull come from? Why did it have so many holes? Years later, after interviewing an elder, he learned that the area was the site of an ancient battle between the Siberian Yupik and Iñupiat tribes. Jon’s curiosity into humanity’s past grew throughout his childhood as he wandered the plains of Alaska, conducted experiments with the science kit that he toted around, and dissected animals he found.

 
After a detour in the security field in his twenties, Jon returned to college to study his passion, archaeology. He’s currently a Master of Arts candidate in Applied Anthropology; his primary research focus lies in helping locate former settlements along the Oregon coast and the Bering Sea. Under the direction of his advisor, ecological anthropologist Drew Gerkey and archaeologist Loren Davis, Jon uses geographic information systems to recreate ice age landscapes as far back as 20,000 years. The goal of this project is to predict the location of underwater archaeological sites off of the Oregon coast, as well as his childhood home along the Bering Sea.

Jon volunteering at the 2014 Connley Caves Field School, where he’s been volunteering for the last three years.

These predictive models are a potentially important key in locating possible underwater sites. Coastlines have shifted over the last 20,000 years, making it difficult to find and excavate former coastal settlements. If located, these sites can preserve important artifacts of the lives of our coastal predecessors.

Jon is also invested in employing native historical and cultural knowledge in his research. For a recent project, “20,000 Year of Isostatically Adjusted Paleoshorelines for Northern Oregon: the Tillamook Peninsula,” Jon worked with Confederated Tribes of Grand Ronde to incorporate traditional knowledge into his research. The Tribes’ input included identifying place names and culturally important locations into the models. This helped researchers understand the cultural, geographic and natural resources of the area.

Horse Farms to Tree Farms: Studying the Relationship Between Land Management and Biodiversity

If you wander forests of the Oregon Coast Range you might encounter a strange sight: exclosures made of timber and steel-braided wire, standing in a clear-cut forest. These exclosures, which stand 100-feet long, 50-feet wide and 8-feet high, are the research and work of Thomas Stokely, a PhD candidate in the department of Forest Ecosystems & Society in the College of Forestry. The exclosures were constructed to study the impact of deer and elk grazing on tree growth, and to address a larger research question in forestry management: What does intensive forest management mean for biodiversity?

To study the impact of deer and elk on commercial tree growth, Thomas constructed constructed 28 stands in which a team of researchers manipulated the intensity of herbicide spray treatments in each area (non-sprayed, light, moderate and intensive herbicide treatments). For six years, under the direction of his adviser Matthew Betts, Thomas and has measured plant communities, arthropods, herbivory and plantation development inside these exclosures and in open plots where wildlife is allowed free access.

The exclosure research in the Oregon Coast Range relates to Thomas’s goals as a scientist who’s invested in understanding how industry impacts biodiversity. “As the world population grows, we need more resources,” he said. “We want to value the product, but we also value biodiversity and wildlife habitat. Is there a way we can manage for both timber production and wildlife habitat? If so, what role do biodiversity and wildlife play in the management of natural resources? If management alters biodiversity or excludes wildlife, what are the implications for ecosystem functioning?” These are questions that continue to drive his research and his career path.

Thomas has been interested in plant-animal interactions and the environment since he was a child. Growing up on a horse farm in southwest Missouri, he watched horses grazing and wondered about their relationship with the habitat in and around the farm. He first considered studying the policy side of humanity’s relationship with the natural world, but political science wasn’t a good fit—he wanted to pursue a more hands-on approach to studying biodiversity. After reading about the reintroduction of wolves in Yellowstone, he knew he wanted to work directly with land and habitat management. He earned a BS in environmental science at University of Missouri before coming to Oregon State. Upon completing his PhD, Thomas plans to work in applied ecology where he hopes to use science to guide land management and conservancy practices.
