  • Light detection and ranging (LiDAR) : what we can and cannot see in the forest for the trees

    Creator:
    Edson, Curtis B.
    Abstract:
    Recently concerns over anthropogenic carbon pollution have received increased global attention and research in forest biomass and carbon sequestration has gained momentum. Light Detection and Ranging (LiDAR) remote sensing has in the last decade demonstrated forest measurement and biomass estimation potential. The project objective was to compare LiDAR forest biomass...

  • 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...

  • Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

    Creator:
    Valente, Jonathon J.
    Abstract:
    Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...

  • Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

    Creator:
    Tanis, Brian P.
    Abstract:
    The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

  • Development of a problem-based learning classification rubric for community college instruction

    Creator:
    Knelly, Leah J.
    Abstract:
    Problem-based learning (PBL) is one type of inquiry-based learning. Many community college instructors use inquiry-based learning as an instructional strategy. There is much literature on the use of problem-based learning in undergraduate, graduate and medical school education, with a multitude of examples of specific techniques and problems to be addressed,...

  • Drivers of Soil Fungal Communities Across Three Tropical Rainforests in Panama

    Creator:
    Schappe, Tyler
    Abstract:
    Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...
