Crested wheatgrass (Agropyron cristatum [L] Gaertm), an introduced bunchgrass, has been seeded on over 5 million hectares of degraded rangeland in western North America because it establishes more readily than native bunchgrasses. Because crested wheatgrass stands are associated with native species displacement and low biological diversity, there is substantial interest...
Improving the understanding the relations of sustainability behaviors in manufacturing systems and actively engaging with manufacturers (especially SMEs) in sustainability efforts is key to the long-term success of U.S. industry and the natural environment. This study addresses this urgent need by establishing a systemic approach for the design of costing...
The investigations were based on a complete diallel cross
among three inbred lines of Hereford cattle. Records of Angus calves
born during the same period were used to obtain more accurate
estimates of environmental effects and to determine breed differences
among the various traits included in the study. Estimates of...
A study was conducted over a two year period, 1973 through
1974, on perennial ryegrass-subclover pastures with stocking rates
of 7.4 (moderate), 9. 9 (heavy), and 12.4 (overstocked) ewes per
hectare to establish guidelines on stocking intensity for dryland
improved pastures in western Oregon. Climatic conditions varied
annually and caused...
Several aspects of cattle grazing behavior and distribution
were studied on mountain rangeland dominated by ponderosa pine-
Douglas fir, mixed conifer, and white fir forest communities in
northeastern Oregon.
The association between upland distribution, determined by
forage utilization and by direct cattle observation, and several
habitat factors was studied through...
Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...
Vaccinia virus encodes at least eight proteins that are modified post-translationally by the addition of a 16-carbon saturated fatty acid through thioester linkage to cysteine residues. This is referred to as palmitylation of proteins. The purpose of this work was to gain an understanding of palmitylation, focusing on what defined...
Vaccinia virus (VV) encodes at least six proteins that are modified by the addition of a 14-carbon saturated fatty acid through an amide linkage and at least eight proteins that are modified post-translationally by the addition of a 16-carbon saturated fatty acid through linkage to cysteine residues. These post-translational modifications...
Beet yellows virus (BYV) is a filamentous, positive-strand RNA virus that belongs to the family Closteroviridae. BYV particles encapsidate a 15.5 kb RNA and posses complex polar architecture. A long virion body is formed by the major capsid protein(CP), whereas the minor capsid protein (CPm) assembles a short tail that...
