Response of brood-rearing habitat of sage grouse to prescribed burning in Oregon

Creator:: Pyle, William H. (William Hanson), 1957-
Abstract:: 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...

Nutrient management and cycling in grass seed crops

Creator:: Horneck, Donald Arthur
Abstract:: 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...

Diel activity patterns in demersal fishes on Heceta Bank, Oregon

Creator:: Hart, Ted
Abstract:: 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...

Phosphorus availability in biosolids-amended soils

Creator:: Choate, Jeff
Abstract:: 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...

Application of Hart's computer simulation to the drying of 2-inch thick Douglas-fir heartwood lumber

Creator:: Kang, Hoyang
Abstract:: 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...
