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...
Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...

Effects of light intensity, exposure to desiccation, reduced
salinity, and thermal elevation on the functional and structural characteristics
of marine benthic diatom communities were investigated
in a laboratory model ecosystem and a respirometer chamber.
Measurements of biomass (dry weight and ash-free dry weight)
and chlorophyll a were made for each...
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;...
