Structure and composition of unmanaged riparian forests in the coastal mountains of Oregon, U.S.A.

Creator:: Pabst, Robert J. and Spies, Thomas A.
Abstract:: We characterized the structure and composition of unmanaged riparian forests in three river basins in Oregon’s coastal mountains. Our objective was to evaluate stand attributes at three spatial scales: streamside (site), drainage network (stream order), and basin (subregion). Data on basal area, species composition, snag density, canopy cover, and tree...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...

Asymptotic height-diameter equations for twenty-four tree species in western Oregon

Creator:: Garman, Steven L. (Steven Lee), 1955-, Acker, Steven A., Ohmann, Janet L., Spies, Thomas A. (Thomas Allen), and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting height from diameter outside bark at breast height (DBH) were generated for 24 tree species in western Oregon. The equations were based on the asymptotic Chapman-Richards function. Because geographic location and site productivity may influence height-diameter relationships, height-diameter measures from 8727 plots were first grouped by site...

Improving the performance of multispan logging systems by suspending the mainline

Creator:: Durston, Thomas A.
Abstract:: Multispan skyline logging systems are cable systems designed to yard logs over steep terrain having a constant or convex slope. An intermediate skyline support is used to raise the skyline high enough to achieve ground clearance without overstressing the skyline. Certain improvements in performance can be realized by providing intermediate...

Control abstraction in parallel programming languages

Creator:: Crowl, Lawrence A. and LeBlanc, Thomas J.
Abstract:: Control abstraction is the process by which programmers define new control constructs by specifying an ordering of statement execution. Using control abstraction, we can create new control constructs for parallel programming, separate the specification of parallelism and synchronization from the rest of the application code, and vary the parallelism exploited...

Seasonal and interannual variablity of pigment concentrations across a California Current frontal zone

Creator:: Thomas, A. C. and Strub, P. Ted
Abstract:: Previously published physical and biological data document a zonally oriented frontal region within the California Current system separating colder and more eutrophic water north of ≈33°N from warmer; more stratified, and oligotrophic water farther to the south. Satellite images of phytoplankton pigment from the coastal zone color scanner from 1979-1983...

Comparison of the seasonal and interannual variability of phytoplankton pigment concentrations in the Peru and California Current systems

Creator:: Thomas, A. C., Huang, F., Strub, P. Ted, and James, C.
Abstract:: Monthly composite images from the global coastal zone color scanner (CZCS) data set are used to provide an initial illustration and comparison of seasonal and interannual variability of phytoplankton pigment concentration along the western coasts of South and North America in the Peru Current system (PCS) and California Current system...

Determination of relative economic weights for multitrait selection in coastal Douglas-fir

Creator:: Aubry, Carol A., Adams, W. T., and Fahey, Thomas D.
Abstract:: Abstract: Relationships between tree traits and tree value for lumber production were investigated. For the purposes of estimating relative economic weights for use in multitrait selection in coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), tree height, diameter at breast height, and branch diameter were measured on 164 trees (ages...
