Drought Conditioning Conifer Seedlings For Post-Fire Management And Climate Change Adaptation, Anna C. Ross

Graduate Student Theses, Dissertations, & Professional Papers

Increased frequency, severity, and duration of drought and increased wildfire severity are together impacting forests of the western U.S. To encourage forest ecosystem resilience to these changing disturbance regimes, there is a need for novel silvicultural techniques that develop seedlings capable of establishing in hotter and drier climates. We evaluated the morphological and physiological effects of a drought conditioning treatment applied in a greenhouse on second- year ponderosa pine (Pinus ponderosa), western white pine (Pinus monticola), and western larch (Larix occidentalis) seedlings. Treatments included a well-watered control (75% of container capacity) and a water-limited …

Interannual Growth-Climate Relationships Of Western Larch After Wildfire In The Northwest, Junior Burks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Montane and mixed-conifer forests in the northwestern United States are burning at rates greater than any time in recent decades, due to the combined impacts of global warming and historical and contemporary land use and land management. Western larch (Larix occidentalis) is a tree of high regional significance, exhibiting a variety of traits that make it resistant and resilient to fire. Because seedlings are more sensitive to environmental stressors than adults, the impacts of climate change are expected to be detectable first in juvenile trees. Recent research shows that the natural regeneration of western larch after wildfires has …

Evaluating Early-Life Characteristics And Responses Of Native Plant Materials For Dryland Restoration, Sophia N. Lasche

Graduate Student Theses, Dissertations, & Professional Papers

Globally, many drylands are in need of restoration due to anthropogenic land use changes, climate change-related biodiversity loss, and broad scale degradation. Within this degradation framework, many perennial grass species and populations have been lost from drylands. A common method of restoring vital perennial grass populations is through seed-based restoration. Using seed-based restoration, or the act of adding desirable seed to a system to restore plant populations, requires a depth of knowledge on species level responses, as well as seed sources within those species. My research examines three workhorse perennial grass species and associated seed sources for dryland restoration, especially …

Wildfires Are Burning Less Frequently And More Severely Than Historically In The Western Us: A Novel Approach To Calculating Fire-Regime Departures, Jeffrey Ryan Chandler

Graduate Student Theses, Dissertations, & Professional Papers

Changing climate, vegetation, and fire exclusion are altering and homogenizing fire-regime attributes compared to historic conditions. Fire-regime changes are commonly quantified using departure metrics, which are often based on measures of central tendency (i.e. changes in the mean). These metrics can mischaracterize complex changes to the distributional characteristics of fire-regime attributes. Here we develop a fire-regime departure metric that quantifies nonparametric distributional changes to fire-regime attributes over time. We use this metric to compare fire frequency and severity between historical (~1600-1880) and contemporary (1880- 2021) time periods in western US forests. Our analysis revealed that 89% of Western US forests …

Density Anomaly Leads To Rift Initiation: Quantifying Active Rifting And Comparison To The East African Rift Zone, Chloe Boucher

Graduate Student Theses, Dissertations, & Professional Papers

Active rifting, elastic failure in the lithosphere from rising density anomalies in the mantle, is fundamental to the Wilson Cycle which describes the cycle of tectonic plates. Active rift zones are common in the oceanic lithosphere but are less common in the thicker continental lithosphere. The current largest active continental rift zone is the East African Rift Zone (EARZ). Although active rifting is fundamental to plate tectonic theory, the mechanics and parameters needed for a density anomaly to initiate a rift have not been undertaken. This model aims to solve the problem of a density anomaly initiating a continental rift …

A Soil-Plant-Atmosphere Continuum Model To Simulate Seedling Response To Water Stress, Michael Kurt Kendree Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Most current ecohydrologic models simplify the hydraulics that are at play in plant-water relationships by assuming that the water content within the plant is static. In reality, plants have a relative water content that varies with time in response to environmental stresses. To some extent, variations in plant relative water content are regulated by changes in the osmotic potential of water within plant cells, which contributes to the resilience of plants during periods of water shortage. We present a model that simulates plant water transport and storage within the soil-plant-atmosphere continuum. The model incorporates the role of osmotic regulation in …

Flower Bases In Full Bloom: Intersecting Families And A Generalization Of Diversity, Ryan Wood

Graduate Student Theses, Dissertations, & Professional Papers

In this work, we present results employing the flower base method. We work in the field of extremal set theory, focusing our attention on r-uniform intersecting families. The classic Erd˝os-Ko-Rado Theorem states that, for n large enough, the largest runiform intersecting family, a so-called maximum star, consists of taking all r-sets containing a fixed element. Lemons and Palmer [31] investigated the diversity function, showing that the largest intersecting family that is the most “un-star-like” consists of taking all r-sets containing at least two members of a set of size three. Our main problem, that of C-weighted diversity, unifies these two …

Identifying And Predicting Patterns Of Snowpack Ripening With Machine Learning Methods, Clement Cherblanc

Graduate Student Theses, Dissertations, & Professional Papers

The timing of water release from the snowpack plays key roles in ecosystem services, groundwater recharge, and water resource management. However, two internal barriers in a standing snowpack must be overcome before runoff can outflow from the base: 1) the cold content must be exhausted, and 2) the interconnected network of snow grains must be filled with liquid water to residual saturation. Expressing the liquid water as latent heat allows the two barriers to be grouped as an energy (J/m²) to define a snowpack’s Runoff Energy Hurdle (REH). The growth and loss of REH is driven by evolution of pore …
