Decline of western sage grouse (Centrocercus urophasianus phaios)
in Oregon may be related to the reduced availability of foods in upland
sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of
this study was to determine primary foods of chicks and the short-term
response of brood-rearing habitat to prescribed burning at Hart...
Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...
Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...
Most fishes exhibit differences in activity patterns from day to night, with a switch from
high to low activity at dusk and reverse at dawn. Marine reef fishes show similar behavior
among sites, despite dissimilar species assemblages, suggesting that common selection pressures
are leading to convergent behavior. Few studies to...
The purpose of this study was to compare the drying curves of
2-inch thick Douglas-fir heartwood boards as predicted by a
computer simulation by C. A. Hart (1983) with those actually
observed in experimental kiln runs. The moisture gradients within
test boards were also simulated by the computer program and...
