As hikers trek through Oak Creek, they might notice its beautiful, crystal clear water, or Douglas-firs that line the banks. But when Assistant Professor Catalina Segura<\/a> looks at Oak Creek, she sees something iconic \u2013 something famous in her world of stream geomorphology.<\/p>\n\n\n\n

\u201cI knew about Oak Creek before I knew about Oregon State University or Corvallis,\u201d she says. \u201cIt\u2019s famous because of the work done there. A very impressive data set was collected there in the late 60s and early 70s. There\u2019s not much else like it in the world.\u201d<\/p>\n\n\n\n

Segura now feels privileged to conduct her own research, related to primary production in streams, at this site.<\/p>\n\n\n\n

Segura says primary production provides the fundamental source of energy for life on earth, and therefore understanding what controls primary production is key to understanding ecosystems. Most of the primary production in streams like Oak Creek come from algae that lives on rocks. That\u2019s why it\u2019s crucial to understand how the movement of rocks in the stream bottom interacts with algae locally and throughout the stream\u2019s reach.<\/p>\n\n\n\n

Segura works with Associate Professor Dana Warren<\/a> on a project funded by the National Science Foundation. Two sites are being compared: Oak Creek and Mill Creek, a tributary of the Siletz River in the Coastal Range.<\/p>\n\n\n\n

Segura says the rocks in each of these streams are very different. The rocks in Oak Creek are basalt and coarser, while the rocks in Mill Creek are sandstone and finer.<\/p>\n\n\n\n

The researchers, together with graduate student Samantha Cargill, collected data on oxygen and used that to model the amount of primary production by algae on rocks.<\/p>\n\n\n\n

\u201cNow that we understand what happens during storm events in the winter when the water runs quickly and the rocks in the bottom move frequently, we can think about seasonal variability. We have a new post-doctoral fellow, Sandra Villamizar, who will take the project in this new direction.\u201d In the meantime, several sensors for this project remain in Oak Creek. They are monitored intermittently. Segura also takes her classes to Oak Creek so undergraduate and graduate students can observe the research happening there.<\/p>\n\n\n\n

\u201cI tell my students about how we collect data and take them to those locations. We look at flow measurements and do a few different labs in the forest,\u201d she says. \u201cLogistically, I appreciate how convenient it is. You can visit Oak Creek as frequently as you want, and it makes it easy to integrate teaching and research.\u201d<\/p>\n\n\n\n

Segura says there are also benefits to Oak Creek being inside a managed forest, managed by the College of Forestry<\/a>.<\/p>\n\n\n\n

\u201cThe forest director, Professor Stephen Fitzgerald, has helped facilitate our research by doing things like restricting access to the stream at sensitive times,\u201d she says.<\/p>\n\n\n\n

The other study area near the Siletz was also convenient. It is located partially on tribal land, and partially on Weyerhaeuser property.<\/p>\n\n\n\n

\u201cLast year we were able to host high school students and teachers through the SMILE: Science Math Investigative Learning Experience program,\u201d Segura says. \u201cWe trained the teachers in different modules to take back to their classes, and that was very gratifying. It\u2019s amazing that so many people can benefit from the interesting work we\u2019re doing thanks to our location.\u201d<\/p>\n\n\n\n
