Calibration of soil moisture sensing with subsurface heated fiber optics using numerical simulation

Creator:: Benítez‐Buelga, Javier, Rodríguez‐Sinobas, Leonor, Sánchez Calvo, Raul, Gil‐Rodríguez, Maria, Sayde, Chadi, and Selker, John S.
Abstract:: The heat pulse probe method can be implemented with actively heated fiber optics (AHFO) to obtain distributed measurements of soil water content (θ) by using reported soil thermal responses measured by Distributed Temperature Sensing (DTS) and with a soil-specific calibration relationship. However, most reported applications have been calibrated to homogeneous...

The effect of burrowing mammals on the hydrology of a drained riparian ecosystem

Creator:: Cassidy, James Richard
Abstract:: Many species of rodents and insectivores live in subterranean burrows in soils throughout the world. The soil surface perforations of burrow entrances are often connected to complex, subsurface tunnel networks. Burrow entrances and associated subsurface tunnel networks represent a link between surface and subsurface ecological function. Anecdotal observations of surface-water...

Feasibility of soil moisture monitoring with heated fiber optics

Creator:: Sayde, Chadi, Gregory, Christopher, Gil‐Rodriguez, Maria, Tufillaro, Nick, Tyler, Scott, van de Giesen, Nick, English, Marshal, Cuenca, Richard, and Selker, John S.
Abstract:: Accurate methods are needed to measure changing soil water content from meter to kilometer scales. Laboratory results demonstrate the feasibility of the heat pulse method implemented with fiber optic temperature sensing to obtain accurate distributed measurements of soil water content. A fiber optic cable with an electrically conductive armoring was...

Intraseasonal Oscillations of ~20 days Revisited: The Jet Stream and its Ecological Implications along the Oregon Coast

Creator:: Herweck, Kendra
Abstract:: Intraseasonal oscillations in the atmosphere-ocean system can affect weather patterns and regional ecosystems. In turn, these oscillations can be affected by climate variability, resulting in additive and/or non-linear responses of regional ecosystems to climate forcing. In the Northern California Current, a strong correlation was identified between the location of the...

A theoretical design of rational autonomy : integrating elementary and early childhood teacher education through a contemporary derivation from Maria Montessori's social cognitive field paradigm

Creator:: Mitchener, Virginia Wedler
Abstract:: The individual through earliest recorded history reveals contradictory views of the human life-span. "Am I a free and unique individual, able to make choices and decide my own destiny?, or, "Am I only a victim of circumstance, a speck of dust in the universe's whirlwind of fate?" Each view is...

Organizational Capacity of Oregon Latino Nonprofits and its Role in Immigrant Integration

Creator:: Vazquez, Maria Dolores
Abstract:: This essay provides an assessment of the human, social and financial resources that Oregon Latino immigrant-serving nonprofits have available to achieve their mission of promoting Latino immigrant integration and civic engagement practices. Under the framework of immigrant integration, this study examines the strategies Latino nonprofits rely upon to achieve their...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

Possible association between grain protein content and yield as influenced by harvest index and biological yield in selected hard red winter wheat (Triticum aestivum L.) crosses

Creator:: Costa, José María
Abstract:: Grain yield and grain protein are often negatively associated in wheat. When yield increases and grain protein decreases, there can be an adverse effect on the milling and baking quality if the desired end product is bread flour. It has been suggested that this inverse association is the result of...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:: Costa, Jose Maria
Abstract:: A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...
