Proper use of vegetation in streambank bioengineering practices requires a comprehensive understanding of the influence of vegetation density on streambank hydraulics. A series of studies were conducted to investigate the relationship between independent variables vegetation density, bank angle, and discharge and dependent variables channel velocity, resistance, turbulence, and shear stress....
Autism Spectrum Disorder (ASD) is described as a developmental disability characterized by impairments in social interaction, communication, and repetitive or restricted movements. It has been shown that as children with ASD age, their cognitive and social skills improve with time, and physical activity has been linked with improving aspects of...
The goal of this project was to develop and test non-herbicidal techniques that remove nonnative
plant or weed seeds from the top 2 inches of the soil. The Nature Conservancy (TNC) is
currently restoring prairies in the Willamette Valley. Some areas of the Pacific Northwest have
already seen loss of...

Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...
We investigated the relationship between calcium and protein intake and bone loss over a one-year period in 99 early postmenopausal women (1-36 months) aged 51.3 ± 0.31 years. Bone mineral density (g/cm²) of the left hip (total hip, femoral neck, greater trochanter) and lumbar spine (L1-L4) as well as body...
A previous study conducted in our laboratory demonstrated the critical role that retronasal odors play in vegetable liking and disliking. It remains unclear, however, why some individuals like certain vegetable odors, while others do not. A possible explanation is that some individuals have learned to like the odor of a...
In the case of lake management for recreational use, policy makers often face a balancing act. They must maintain both the ecological quality of sites and the welfare of recreationists. In Wisconsin's Northern Highland Lake District, recreational boaters inadvertently transport aquatic invasive species between lakes. Economic models of boater demand...
Water availability is a controlling factor in stream ecosystems with direct influences on habitat and aquatic ecosystem process, but little work has been done evaluating how biota respond to natural variations in low flow conditions during summer, and which biotic or abiotic features in the system may link most closely...
Recreational and Commercial fisheries and the quality of aquatic habitats in which the fish live are an important part of the livelihoods and economy of the Oregon Coast. The composition of important juvenile fish assemblages in estuaries can bring a unique view into the needs of different species on a...
One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...
