    Distribution of fishes, both occupancy and abundance, is often correlated with landscape-scale characteristics (e.g., geology, climate, and human disturbance). Understanding these relationships is essential for effective ...
  • Large Predators Limit Herbivore Densities in Northern Forest Ecosystems 
    Ripple, William J.; Beschta, Robert L. (Springer, 2012)
    There is a lack of scientific consensus about how top-down and bottom-up forces interact to structure terrestrial ecosystems. This is especially true for systems with large carnivore and herbivore species where the effe ...

    The effects of initial leaf litter chemistry on first-year decomposition rates were studied for 16 common Pacific Northwest conifers, hardwoods, and shrubs at the H.J. Andrews Experimental Forest in western Oregon. Leaf ...
  • Lean in red alder (Alnus rubra): growth stress, tension wood, and righting response 
    Wilson, B. F.; Gartner, B. L. (NRC Canada, 1996)
    Natural stands and a 3-year-old plantation of red alder (Alnus rubra Bong.) trees were used to study the incidence of leaning stems, the level of growth stresses and tension wood formation, and the ability of the stems t ...
  • The logistics of working with poison oak 
    Gartner, Barbara Lachenbruch (1990)
    This appendix to my dissertation documents how I worked with poison oak plants as a subject of study for three years. It contains practical suggestions for people who have my level of sensitivity (low to moderate). I e ...
  • Long-term patterns of diameter and basal area growth of old-growth Douglas-fir trees in western Oregon

    Diameter growth and age data collected from stumps of 505 recently cut old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees at 28 sample locations in western Oregon (U.S.A.) indicated that rapid early and ...
  • Mapping and imputing potential productivity of Pacific Northwest forests using climate variables 
    Latta, Gregory; Temesgen, Hailemariam; Barrett, Tara M. (NRC Research Press, 2009)
    Regional estimation of potential forest productivity is important to diverse applications, including biofuels supply, carbon sequestration, and projections of forest growth. Using PRISM (Parameter-elevation Regressions o ...
  • Mapping Migratory Bird Prevalence Using Remote Sensing Data Fusion 
    Swatantran, Anu; Dubayah, Ralph; Goetz, Scott; Hofton, Michelle; Betts, Matthew G.; Sun, Mindy; Simard, Marc; Holmes, Richard (Public Library of Science, 2012-01-03)
    Background: Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable po ...
  • Maximum height in a conifer is associated with conflicting requirements for xylem design 
    Domec, J.-C.; Lachenbruch, B.; Meinzer, F. C.; Woodruff, D. R.; Warren, J. M.; McCulloh, K. A. (National Academy of Sciences, 2008)
    Despite renewed interest in the nature of limitations on maximum tree height, the mechanisms governing ultimate and species-specific height limits are not yet understood, but likely involve water transport dynamics. Tall ...
  • Method to Determine Locations of Tsunami Vertical Evacuation Shelters 
    Park, Sangki; van de Lindt, John W.; Gupta, Rakesh; Cox, Daniel (Springer, 2012-09)
    The 2004 Indian Ocean tsunami and the 2011 Great Tohoku Japan earthquake and tsunami focused a great deal of the world’s attention on the effect of tsunamis on buildings and infrastructure. When a tsunami impacts structu ...
