This research examines the community composition of biotic soil crusts at nine
sites in central and eastern Oregon, U.S.A. At each site, data were collected in one pair
of livestock-grazed and excluded transects. Variables recorded included: cover of biotic
soil crusts and vascular plant species, soil surface pH, electrical conductivity,...

Elliptical borehole enlargements or "breakouts" caused by systematic spalling of a
borehole wall due to regional maximum horizontal stresses were identified in 18 wells
drilled in the Coast Range and Willamette Valley of western Oregon. The breakouts
generally indicate a NNW to NNE orientation of maximum horizontal compression

Local property-owning residents maintain high levels of interest
and awareness regarding a neighboring natural resource complex.
Factors, however, such as proximity, personal interests, use patterns
and economic considerations cause local inhabitants to have an
inaccurate perception of the natural resource complex. The nature
of local resident perception can be analyzed...

Floods and ensuing damage have always been a problem for man.
Initial reaction to the frequent destruction was to avoid siting
permanent domiciles on flood-prone lands. As a result of increasing
population and pressure for development, flood control structures
were built. Instead of reducing flood losses, however, flood control
projects...

Epidemiological studies on Greenland Inuits in the 1970s and subsequent human studies have established an inverse relationship between the ingestion of omega-3 fatty acids [C₂₀₋₂₂ ω3 polyunsaturated fatty acids (PUFA)], blood levels of C₂₀₋₂₂ ω3 PUFA and mortality associated with cardiovascular disease [CVD]. C₂₀₋₂₂ ω3 PUFA have pleiotropic effects on...
