Understanding the mechanisms controlling colloid transport and deposition in the vadose zone is an important step in protecting our water resources. Colloid transport in unsaturated porous media was studied using X-Ray Microtomography (XMT), which is a non-destructive imaging technique that provides three-dimensional images at a resolution on the order of...
The College of Forestry Integrated Research Project (CFIRP) is an on-going experiment in the eastern Coast Range foothills of western Oregon. Started in 1989, a team of scientists, resource managers, and students at Oregon State University designed and implemented silvicultural alternatives to clearcutting. These silvicultural practices aimed to create and...
The Pacific lamprey (Entosphenus tridentatus) is in decline in the Columbia River Basin, and translocating adult lamprey to bypass difficult migration corridors has been implemented since 2000. We describe and report results from two current translocation programs, provide context for use of translocation, and discuss potential benefits, risks, and uncertainties....
From detailed fieldwork and biotite ⁴⁰Ar/³⁹Ar dating correlated with paleomagnetic analyses of lithic clasts, we present a revision of the stratigraphy, areal extent and volume estimates of ignimbrites in the Cerro Galan volcanic complex. We find evidence for nine distinct outflow ignimbrites, including two newly identified ignimbrites in the Toconquis...
Previous game-theoretic studies of vaccination behavior typically have often assumed that populations are homogeneously mixed and that individuals are fully rational. In reality, there is heterogeneity in the number of contacts per individual, and individuals tend to imitate others who appear to have adopted successful strategies. Here, we use network-based...
Global Positioning System vectors and surface
tilt rates are inverted simultaneously for the rotation of western
Oregon and plate locking on the southern Cascadia subduction
thrust fault. Plate locking appears to be largely
offshore, consistent with earlier studies, and is sufficient to
allow occasional great earthquakes inferred from geology.
Clockwise...
This guide provides tree fruit growers with the latest information on pesticides and herbicides for fruit trees. People who grow apples, pears and cherries can learn application rates and recommendations for each stage of tree growth.
Published January 2020. A more recent revision exists. Facts and recommendations in this publication...
The degree of wildfire risk depends on both the probability of an ignition and the potential for damage or harm (such as loss of trees, homes, or even lives). Recognizing that you may have a high wildfire risk is the first step in doing something about it. Whether you own...
