Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made difficult by the scarcity of Southern Hemisphere paleoclimate records. We use a new glaciochemical record of a coastal ice core from...
The purpose of this thesis is to derive and compare asymptotic
performances of certain tests of independence, interchangeability
and equality of the distributions of_ratios Y/X for positive variates
and Y with joint c.d.f. H(x,y) of particular forms. Three bivariate
families, Morgenstern, Plackett, and Moran, are considered which permit
marginal c.d.f.'s...
The eddy-covariance method often underestimates fluxes under stable, low-wind conditions at night when turbulence is not well developed. The most common approach to resolve the problem of nighttime flux underestimation is to identify and remove the deficit periods using friction-velocity (u*) threshold filters (u*[superscript Th]). This study modifies an accepted...
Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...

The main focus was on developing an algorithm and supporting computer programs for use by extension personel to counsel farm managers on problems of enterprise choice. Investigation was initiated from the complete certainty viewpoint of linear programming. Upon introducing uncertainty, ramifications of changing expected income, variance and the correlation coefficient...
The behavior of individuals in decision making under risk was
investigated using choice structures of greater complexity than the
types examined in previous studies. The experiment performed consisted
of two phases. In Phase I a basic utility function for money
was derived for each subject using lotteries with two equally...
Many miles of roads are built in the Pacific Northwest Forests to provide access for logging and fire protection. Logging roads often cross steep mountainous terrain. Logging roads and the associated cut and fill slopes represent a discontinuity in the natural stress state in the soil mantle. These conditions result...
We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
Intraspecific assisted migration (ISAM) through seed transfer during artificial forest regeneration has been suggested as an adaptation strategy to enhance forest resilience and productivity under future climate. In this study, we assessed the risks and benefits of ISAM in white spruce based on long-term and multilocation, rangewide provenance test data....
Vegetation carbon uptake and respiration constitute the largest carbon cycle of the planet with an annual turnover
in the order of 120 GT. Currently, neither ecosystem carbon uptake (through photosynthesis) nor ecosystem
carbon release (through respiration) can be measured directly during the daytime. Instead, flux-tower measurements
rely on nighttime respiration...
The success of civil engineering construction in cold regions often depends on the
assessment of the potential for frost heave. Over the past two decades two models have
been presented to the engineering community to identify the frost heave potential,
namely: (1) the segregation potential (SP), and (2) the discrete...
The exchange of carbon dioxide is a key measure of ecosystem metabolism and a critical intersection
between the terrestrial biosphere and the Earth’s climate. Despite the general agreement that
the terrestrial ecosystems in North America provide a sizeable carbon sink, the size and distribution
of the sink remain uncertain. We...

Schizopora paradoxa KUC8140 is a white rot wood degrader commonly found in Korea. Tolerance to heavy metals and polycyclic aromatic hydrocarbons and dye decolorization activity make this strain a potential candidate for mycoremediation. We report the genome sequence of S. paradoxa KUC8140 containing 44.4 Mbp. Based on ab initio gene...
Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...
Treatment providers seek low-cost, high-impact means of engaging clients in care with the aim to enhance treatment delivery and outcomes. With improvements to mobile technology making cell phone accessibility and usage rates high across all socio-economic levels, text messaging is becoming more frequently utilized as a means of promoting provider-client...
Two direct elicitation of utility (D.E.U.) techniques
were used to estimate risk attitudes of a group of agricultural
producers. The two elicitation techniques used in the
study were 1) an error-in-response model using a modified
Ramsey method, and 2) stochastic dominance with respect to a
function (SDF). The primary objective...
