Leaf processing behaviour in Atta leafcutter ants: 90% of leaf cutting takes place inside the nest, and ants select pieces that require less cutting

Creator:: Garrett, Ryan W., Carlson, Katherine A., Goggans, Matthew Scott, Nesson, Michael H., Shepard, Christopher A., and Schofield, Robert M. S.
Abstract:: Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates...

Mapping disturbance interactions from earth and space : insect effects on tree mortality, fuels, and wildfires across forests of the Pacific Northwest

Creator:: Meigs, Garrett W.
Abstract:: Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...

Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...

Leslie Marmon Silko and the New Sincerity

Creator:: Lackey, Ryan W.
Abstract:: One reading of the post-postmodern literary period argues that as formal aesthetics have (re)engaged with ethics there has been a concomitant move to treat literature as a space of ethical potential. Adam Kelly has called this attitude, when combined with the appropriation of certain metafictional and postmodern techniques, the “New...

Evaluation of the intergovernmental relationships between national and state wetland regulatory agencies within wetland regulatory units

Creator:: Taylor, Ryan W
Abstract:: Since the 1890s, American federalism has been perceived as being unique in the world by having two different levels of government operating within the same jurisdiction without influencing one another. Modern scholars call into question the validity of this basic assumption, but few have published quantitative evidence to reject its...

Modeling Oregon’s biodiesel subsidies and their potential effects on the Willamette Valley agricultural landscape

Creator:: Siegel, Ryan W.
Abstract:: The beginning of the twenty-first century has seen an upsurge in petroleum prices and an increased concern over greenhouse gas emissions. Consequently, the interest in biodiesel production has heightened. Policy at the Federal level, such as the blender’s tax credit which provides $1 for every gallon of biodiesel blended with...

A Landsat time series approach to characterize bark beetle and defoliator impacts on tree mortality and surface fuels in conifer forests

Creator:: Meigs, Garrett W., Kennedy, Robert E., and Cohen, Warren B.
Abstract:: Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...

‘Oregon Snowflake’ Flowering Currant

Creator:: Contreras, Ryan N. and Friddle, Mara W.
Abstract:: Flowering currant (Ribes sanguineum Pursh.), also known as winter currant, is native to the West Coast of the U.S., primarily west of the Coast Range from Southern California north to British Columbia with populations also occurring in Idaho. The species is prized for its early spring flowers in pendulous racemes...

Acceptance, Acceptability, and Trust for Sagebrush Restoration Options in the Great Basin: A Longitudinal Perspective

Creator:: Gordon, Ryan, Brunson, Mark W., and Shindler, Bruce
Abstract:: In surveys of residents in three urban and three rural locations in the Great Basin we examined the social acceptability of six management practices showing promise for restoring sagebrush-dominated rangelands. Unlike most studies of range management perceptions that have relied on single measurements, we used longitudinal data from a questionnaire...
