Computational analysis of small RNAs and the RNA degradome with application to plant water stress
Water shortage is one of the most important environmental stress factors that affects plants, limiting crop yield in large areas worldwide. Plants can survive water stress by regulating gene expression at several levels. One of the recently discovered regulatory mechanisms involves small RNAs …

Soil and plant water stress in an Appalachian oak forest: its relationship to topography and forest site quality
… was used to investigate soil moisture and plant water stress relationships on the southeast face of Potts mountain in Craig County, Virginia. Topographical effects on available water are especially pronounced during low late season rainfall levels encountered in the Ridge and Valley …

Beaver moderated fire resistance in the North Cascades and potential for climate change adaptation
… more intense fires. Intense burns can alter watershed hydrology, increasing the potential for harmful channel incision, which impairs riparian ecosystem function by lowering the water table, disconnecting floodplains from aquatic environments. However, wetlands and functioning riparian zones …

Non-Contact Sensing for Protected Cropping
… offer a controlled environment for optimized plant growth, but traditional sensing techniques for monitoring plant health and crop quality are often invasive, costly, and labor-intensive. This thesis explores innovative, non-contact sensing methodologies to address key challenges in plant …

Evaluating soil productivity and climate change benefits of woody biochar soil amendments for the US Interior West
… solution to enhance soil capacity to deliver water and nutrients to plants while decreasing climate impacts through reduced nitrous oxide (N2O) emissions from fertilizer use and carbon (C) sequestration. This dissertation evaluates such claims for woody biochar applications within the US …

Autonomous Multi-Sensor and Web-Based Decision Support for Crop Diagnostics in Greenhouse
An autonomous machine vision guided plant sensing and monitoring system was designed and constructed to continuously monitor plant related features: color (red-green-blue, hue-saturation-luminance, and color brightness), morphology (top projected canopy area), textural (entropy, energy, contrast, …

Soil Moisture Dynamics and Thresholds for Surface Energy Balance Regime Transitions: An Observational Analysis at a U.S. Grassland Site
… soil progressively dries due to evaporation and plant uptake—is critical for assessing plant water stress, surface energy partitioning, and land–atmosphere interactions. These periods of moisture loss, commonly referred to as soil moisture drydowns, provide a valuable window into the transition …

Soil-Plant-Atmosphere Coupling during Interstorm Periods
… However, characterizing vegetation responses to water stress and other environmental drivers is challenging because these forcing factors are inter-related, especially on seasonal timescales. Here, newly available global mapping measurements from microwave satellite sensors are used to …

Development of mechanistic energy balance models for grassland
… near-surface soil and air temperatures and plant water use. Therefore it is important to understand how grasslands partition the energy they receive into heat and vapour fluxes, and soil heat flux which regulates the underlying soil temperatures. The project described in this thesis was …
