  • 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...

  • 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...

  • Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

    Creator:
    Naylor, Leslie M.
    Abstract:
    I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

  • Local and downstream effects of contemporary forest harvesting on streamflow and sediment yield

    Creator:
    Zégre, Nicolas P.
    Abstract:
    This dissertation is a collection of three manuscripts that serve to fill the knowledge gaps and advance methods of detecting the effects of contemporary forest harvesting in experimental catchment studies. While there is a preponderance of studies evaluating the environmental effects of forest harvesting in the western United States, few...

  • 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...
