Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...

3,3'-Diindolylmethane Induces G₁ Arrest and Apoptosis in Human Acute T-Cell Lymphoblastic Leukemia Cells

Creator:: Shorey, Lyndsey E., Hagman, Amanda M., Williams, David E., Ho, Emily, Dashwood, Roderick H., and Benninghoff, Abby D.
Abstract:: Certain bioactive food components, including indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) from cruciferous vegetables, have been shown to target cellular pathways regulating carcinogenesis. Previously, our laboratory showed that dietary I3C is an effective transplacental chemopreventive agent in a dibenzo[def,p]chrysene (DBC)-dependent model of murine T-cell lymphoblastic lymphoma. The primary objective of the...

General management principles and a checklist of strategies to guide forest biodiversity conservation

Creator:: Lindenmayer, D.B., Franklin, J.F., and Fischer, J.
Abstract:: Many indicators and criteria have been proposed to assess the sustainable management of forests but their scientific validity remains uncertain. Because the effects of forest disturbances (such as logging) are often specific to particular species, sites, landscapes, regions and forest types, management ‘‘shortcuts’’ such as indicator species, focal species and...

Diversity and distribution of Frankia strains symbiotic with Ceanothus in California

Creator:: Oakley, Brian, North, Malcolm, Franklin, Jerry F., Hedlund, Brian P., and Staley, James T.
Abstract:: Frankia strains symbiotic with Ceanothus present an interesting opportunity to study the patterns and causes of Frankia diversity and distribution within a particular host infectivity group. We intensively sampled Frankia from nodules on Ceanothus plants along an elevational gradient in the southern Sierra Nevada of California, and we also collected...

Management of Riparian Buffers: Upslope Thinning with Downslope Impacts

Creator:: Ruzicka, Kenneth J., Jr., Puettmann, Klaus J., and Olson, Deanna H.
Abstract:: We examined the potential of using upslope density management to influence growth and drought tolerance of trees in untreated downslope riparian forests. Increment cores from Douglas-fir trees in three mature stands in western Oregon, USA, were collected and measured. Trees responded to an apparent edge effect up to 15 m...

Single photon timing system for picosecond fluorescence lifetime measurements

Creator:: Turko, Bojan T., Nairn, John A., and Sauer, Kenneth
Abstract:: A single‐photon timing system is described which is capable of extracting fluorescence lifetimes as short as 25 ps. The system is an improved version of an earlier apparatus. The new system uses a synchronously pumped, mode‐locked dye laser with 10‐ps pulses operating at 82‐MHz repetition rate. A fast photodetector and...

Aircraft measurements of high average charges on cloud drops in layer clouds

Creator:: Beard, Kenneth V., Ochs, Harry T., III, and Twohy, Cynthia
Abstract:: The first reliable aircraft measurements of characteristic cloud drop charges were obtained by utilizing a counterflow virtual impactor to substantially increase charge sensitivity and eliminate spurious contact charging that contaminated previous aircraft measurements. We find average drop charges more than an order of magnitude larger than expected from mountain surface...

Gas-phase structure of nickel dichloride. An electron-diffraction investigation augmented by ab initio and DFT calculations

Creator:: Eddy, Larry L. and Hedberg, Kenneth
Abstract:: The structure of nickel dichloride in the vapor at ca. 1050 K has been studied experimentally by electron diffraction and theoretically by ab initio and DFT molecular orbital calculations. The molecule is found to have a linear equilibrium structure, and from all levels of theory it is predicted to have...

Estimating Habitat-Specific Abundances of PIT-Tagged Juvenile Salmonids Using Mobile Antennas: A Comparison with Standard Electrofishing Techniques in a Small Stream

Creator:: Sloat, Matthew R., Baker, Peter F., and Ligon, Franklin K.
Abstract:: The use of passive integrated transponder (PIT) tags in ecological studies is increasingly common, but evaluations of their performance and range of application in the field are still emerging. Here, we compare habitat unit–scale abundance estimates of PIT-tagged juvenile coho salmon Oncorhynchus kisutch and steelhead O. mykiss derived from multiple-pass...

Facilitative and competive effects of a N-fixing shrub on white fir saplings

Creator:: Oakley, Brian B., North, Malcolm P., and Franklin, Jerry F.
Abstract:: In Sierra Nevada forests, shrubs are considered strong soil moisture competitors with regenerating trees, reducing seedling establishment, and slowing growth. Recent studies, however, suggest that in some circumstances shrubs can facilitate tree establishment and growth by modifying harsh microclimate conditions; increasing acquisition of water, carbon, and/or nutrients via shared mycorrhizal...
