Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of climate change and forest management practices in the increase is unclear. We analyzed tree-ring chronologies from six late-successional...
Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) growth in the Pacific Northwest is affected by climatic, edaphic factors and Swiss needle cast (SNC) disease. We examine Douglas-fir growth responses to temperature, dew point deficit (DPD), soil moisture, and SNC using time series intervention analysis of intra-annual tree-ring width data collected...

Population development of the symphylan, Scutigerella immaculata
(Newport), was studied in laboratory cultures. Also symphylan
injury to greenhouse plants was investigated. Plastic polyethylene
containers partly filled with damp ground hemlock bark were used to
culture symphylan in the laboratory. Fresh lettuce food was supplied
to the cultures weekly.
Factors which...
This study focused on the relationship between parental attitudes
and the conscience orientation of children, testing the hypotheses that
(1) parents who had children with an external conscience orientation
would show significantly greater disparity between their independence
granting and achievement inducement attitudes than parents whose
children had conventional or humanistic...
Experiments were performed to determine the rate of recolonization of sediment-associated microalga and effects of infauna on microalgal biomass and production. Estuarine sediment was defaunated and transplanted to the field and the laboratory. Recolonization of sediment by flora and fauna, relative to control sediment, was measured by chlorophyll a, gross...
This paper presents detailed information of value in experimental work in the laboratory and in promoting the effeciency of commercial paper-making plants employing the soda process.
Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...
The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...
The economic status of the Black Americans has lagged far behind that of non-Black Americans in the last four centuries. The major reasons are manifested in (1) discrimination in employment
practices by: employers, public and private employment agencies, labor organizations, and apprenticeship agencies; and (2) discrimination in distribution of factor...
The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To better understand present temperature regimes, we assembled a 29-year nearshore time series of mean monthly...
Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...

Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area...
Many aquatic habitats in coastal Oregon have been impacted by historic land use practices that led to losses of in-stream wood and associated degraded fish habitats. Many of these streams are now bordered by stands of dense second growth forests (30–80 years) that are incorporated into riparian buffer zones with...
Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...

We investigated DNA methylomes of pediatric B-cell
acute lymphoblastic leukemias (B-ALLs) using
whole-genome bisulfite sequencing and high-definition
microarrays, along with RNA expression
profiles. Epigenetic alteration of B-ALLs occurred in
two tracks: de novo methylation of small functional
compartments and demethylation of large intercompartmental
backbones. The deviations were exaggerated

We compiled a lake-water clarity database using publically available, citizen volunteer observations made between 1938 and 2012 across eight states in the Upper Midwest, USA. Our objectives were to determine (1) whether temporal trends in lake-water clarity existed across this large geographic area and (2) whether trends were related to...

Assessing uncertainties in hydrologic models can improve accuracy in predicting future streamflow. Here,
simulated streamflows using the Variable Infiltration Capacity (VIC) model at coarse (1/16°) and fine (1/120°)
spatial resolutions were evaluated against observed streamflows from 217 watersheds. In particular, the adequacy
of VIC simulations in groundwater- versus runoff-dominated watersheds...
Vegetation structure quantified by light detection and ranging (LiDAR) can improve understanding of wildlife occupancy and species-richness patterns. However, there is often a time lag between the collection of LiDAR data and wildlife data. We investigated whether a time lag between the LiDAR acquisition and field-data acquisition affected mapped wildlife...
