This research was designed to evaluate the effect of
sheep grazing on Douglas-fir water potential, growth, and
understory forage production in a small-scale silvopastoral
agroforestry system, at Peavy arboretum approximately
13 km North of Corvallis, Oregon. Treatments
examined included all possible combinations of two sheep
grazing management treatments (grazed vs....
The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...
Frequent or lengthy predation risk can cause one of two modifications of prey feeding
behavior: 1) postponement of feeding to less risky periods, or 2) resumption of feeding
behavior despite persistent risk. North Pacific flatfishes exhibit both of these responses when confronted with temporal variation in risk, and this experimental...
