Because riparian canopy controls most energy inputs to stream
ecosystems, it directly affects the structure of aquatic food webs and the
ecological processes that govern interactions among trophic levels. This
study addresses the interdependence among riparian canopy, benthic
community structure, and the carrying capacity of high desert streams for
As Si MOS approaches its maximum limits in speed and bandwidth, new
devices are desired to meet the needs of high speed communications and signal
processing. A device that exhibits superior performance to Si MOS, BJT, and
GaAs technology is the HEMT (high electron mobility transistor).
The HEMT offers superior...
Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate
the effects of integrating conservation tillage and cover cropping on broccoli production
as well as agroecological parameters.
A field experiment was conducted during 1996-97 at the Oregon State University
Horticulture Research farm near Corvallis, OR. The specific objectives...
