It has been suggested that thinning trees and other fuel-reduction practices aimed at reducing the probability
of high-severity forest fire are consistent with efforts to keep carbon (C) sequestered in terrestrial pools, and
that such practices should therefore be rewarded rather than penalized in C-accounting schemes. By evaluating how fuel...
Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...
Christian communities vary widely in their degrees of acceptability or apprehensiveness toward newly developing technologies, ultimately aiming to help individuals optimally grow in their relationships to God and with others. Technologies viewed as conducive to accomplishing these goals are more likely to be accepted by Christian communities. Technologies viewed as...
Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....

The ratio of live crown length to tree height (crown ratio; CR) is often used as an important predictor variable for tree level growth equations, particularly for multi-species and multi-layered stands. Also, CR indicates tree vigour and can be an important habitat variable. Measurement of CR for each tree can...
The variability of coastal carbonate chemistry continues to provide significant hurdles for understanding interactions between anthropogenic and natural CO2 cycling and resultant effects on coastal acidification dynamics. Attribution of the anthropogenic component is vital for identifying the impacts of increasing atmospheric carbon on coastal habitats such as coral reefs, upwelling...
Permeability, effects of age, and water table fluctuations were
studied for nine drainfields in five soil types ranging from well to
poorly drained. Three sites were in Willamette, one in Woodburn,
two in Amity, two in Concord, and one in Dayton soils. Before
permeability of drainfields could be evaluated, methods...
Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...
Preliminary nuclear design studies have been completed on ten
configurations of nuclear reactors for low power (1-30 kWe) space
applications utilizing thermionic energy conversion. Additional design
studies have been conducted on the TRICE multimegawatt in-core
thermionic reactor configuration. In each of the cases, a reactor
configuration has been determined which...
