  • Spatially-explicit prediction of recoverable harvesting residues

    Creator:
    Schmidt, Christian F. W.
    Abstract:
    In order to decide whether or not to develop biomass energy facilities and where to best locate them, developers and investors need accurate assessments of fuel supply. This includes information about the distribution and concentration of fuel throughout the assessment area, the quality of fuel (form, moisture content, contaminant content,...

  • Cryptogam communities in forest and steppe ecosystems of Oregon, USA

    Creator:
    Root, Heather T.
    Abstract:
    I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...

  • Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

    Creator:
    Kavanaugh, Maria T.
    Abstract:
    Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

  • Estimation and modeling of selected forest metrics with lidar and Landsat

    Creator:
    Strunk, Jacob L.
    Abstract:
    Lidar is able to provide height and cover information which can be used to estimate selected forest attributes precisely. However, for users to evaluate whether the additional cost and complication associated with using Lidar merits adoption requires that the protocol to use lidar be thoroughly described and that a basis...

  • Optimizing the primary forest products supply chain : a multi-objective heuristic approach

    Creator:
    Hamann, Jeff D.
    Abstract:
    This thesis is a collection of four submitted manuscripts that present methods to assist forest ecosystem service managers wanting to develop operational sampling, monitoring, and production plans for a set of specific quantifiable ecosystem services, which are formulated as a series of general multi-objective optimization problems. The problems are solved...

  • Predator Conservation and Trophic Ecology

    Creator:
    Wolf, Christopher
    Abstract:
    Many of Earth’s terrestrial large carnivore species are threatened with extinction. As a result, some of the ecological effects associated with these species may be lost. With the goal of furthering large carnivore conservation research, I conduct three global scale analyses involving these species. First, I explore prey depletion as...
