Stream buffer strips are an important tool for protecting the stream environment. This research documents the losses from 40 stream buffer strips, in the Western Cascades of Oregon, established 1 to 15 years before the study. Predictive equations are developed
which identify the major reasons for buffer strip losses. Losses...
Fluxes of sulphur dioxide to wheat were measured over two growing seasons. The deposition velocity, vg, depended primarily on affinities of surfaces for SO2 and varied from less than 0.1 to about 1.5cms−1. Stomata were an important sink, and diurnal changes in stomatal resistance accounted for most of the variation...

The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...
The ability of mercury to inhibit β - galactosidase activity from
cell-free extracts of Streptococcus lactis, Escherichia colt and
intestinal homogenates of hogs, female rats, and humans was studied. Mercuric acetate was added in vitro to all sources of β - galactosidase except for the rats, which were placed on...
Activities of lipoprotein lipase (LPL) and hormone-sensitive
lipase (HSL) in adipose tissue, accumulation of carcass fat, and
serum triglyceride have been determined in meal-fed (MF) and
ad libitum-fed (AD) rats. At each feeding frequency, the animals
received diets providing total fat as 15% or 30% of calories and
polyunsaturated fatty...
Prior to onset of the breeding season, a ration containing 18.4 mg/kg N-(Ethylmercuri)-p-toluene sulphonanilide was fed to 6 male and 16 female ring-necked pheasants (Phasianus colchicus). Birds
receiving the mercury-treated ration were separated from the opposite sex. After receiving the mercury-treated ration for 0, 2, 4, 8, or 16 days,...
