Various vineyard practices influence the quality of a wine. In 1999, three levels of nitrogen (N), two levels of tillage and two levels of irrigation were applied to Pinot noir grape cultivars at Benton Lane Vineyards in the Southern Willamette Valley. N treatments were zero, soil and foliar applications. Every...
Stream systems in the Pacific Northwest have come to be understood in the absence of beaver (Castor canadensis). To understand the effect of beaver upon riparian plant communities, four basins in the lower Alsea drainage were examined to determine the effect of beaver and their impoundments on streamside herbaceous/shrub and...
Concerns about the extent to which major Pacific Northwest floods over the last decade might have been exacerbated by logging have heightened the need for a better scientific understanding of the role of forest maturity on snow accumulation and melt. To address this need, a multi-scale field and modeling study...
An organisms' genotype may not be reflected in its phenotype. For example, epistasis - the interaction of non-allelic genes can cause deviations from expected phenotypic ratios. The epistatic interaction between the hooded (Kap) and short-awned (lks2) loci in barley (Hordeum vulgare) precludes the localization of the Kap locus, based on...
