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...

Spatiotemporal Associations of Abundance and Vital Rates of Co-occurring Small Mammals in a Late Successional Forest

Creator:: Weldy, Matthew J.
Abstract:: Informed conservation of small mammals, ecosystems, and predators requires a detailed understanding of how small mammals species and communities vary in both space and time, as well as the relative cyclicity and synchrony of this variation. This variation can be especially informative to land managers interested in manipulating the abundance...

The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Creator:: Takahashi, Mayumi
Abstract:: This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) examine if the vegetation composition and structure of the riparian forest varied among channel-reach morphologies, 2) examine...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

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...

Aquatic food web responses to patchy shading along forested headwater streams

Creator:: Heaston, Emily
Abstract:: In small forested streams, changes in age and structure of riparian vegetation covering the stream have been shown to directly influence the amount of light reaching the stream benthos. Light has the potential to impact in-stream resources that support secondary production through constraints on primary productivity. The influence of landscape...

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...

A macroscale measurement and modeling approach to improve understanding of the hydrology of steep, forested hillslopes

Creator:: Graham, Christopher Brian
Abstract:: The dominant controls on flow generation in steep, forested hillslopes are poorly understood. This dissertation examined the dominant flow processes operating at the hillslope scale, using a combined macroscale measurement and model development and analysis framework. Irrigation experiments at two steep forested hillslopes were conducted to isolate individual hillslope flow...

Characterization of load transfer in wood-based composites

Creator:: Schwarzkopf, Matthew John
Abstract:: The mechanical performance of composite materials is determined by the mechanical properties of their individual components and the effective load transfer between these components. Binders are commonly used to bond composite components together and to provide effective load transfer between them. In wood-based composites the binder-component load transfer occurs at...
