Sierra Nevada Brewery Design Project
The Sierra Nevada Brewery senior design group, throughout this semester, completed a capstone design project for ChE 482. The project encompassed design of two chemical processes, one to produce beer and another to process brewery waste. To fulfill this assignment, research and calculations were …

Population Dynamics of Willow Flycatchers in the Sierra Nevada
… now breed exclusively in montane meadows in the Sierra Nevada and Cascades. Surveys in the 1980s and 1990s indicated that populations were declining in the south and central Sierra Nevada. My research focused on how multiple factors influenced reproductive performance of flycatchers and the …

Created Ponds as Indicators of Restored Sierra Nevada Meadow Hydrology
… restoration of wet-meadow systems in the Sierra Nevada. Pond-and-plug restoration reconnects the stream with its historic floodplain and dams eroded gullies, which then fill with water, creating a series of ponds. Elevated groundwater tables and stream flooding return natural function and …

Post-Fire Sedimentation and the Risk to Sierra Nevada Water Supply
<p>In California, the Sierra Nevada region is crucial for the state’s water supply. Unfortunately, forested areas in important Sierra Nevada watersheds are being increasingly threatened by the growing risk of large, severe wildfires and in turn so are the water supplies that they support. This …

A Vascular Flora of the Sacatar Trail Wilderness, Sierra Nevada, California
… bioregional transition zone in the southeastern Sierra Nevada. The ca. 233 km 2 (90 mi 2 ) study area, located 32 km (20 mi) northwest of the city of Ridgecrest, ranges from 930 to 2698 m (3051–8851 ft) in elevation. The highly diverse California Floristic Province, Great Basin, and Mojave Desert …

Short-term effects of wildfire on Sierra Nevada bighorn sheep habitat ecology
… vegetation and habitat selection by endangered Sierra Nevada bighorn sheep (Ovis candensis sierrae; hereafter Sierra bighorn) for 2 years following wildfire on winter ranges in eastern California. We hypothesized that wildfire would change both forage availability and predation risk. Green …

The structural architecture of seismogenic faults, Sierra Nevada, California; implications for earthquake rupture processes
… are observed to nucleate. Faults exposed in the Sierra Nevada, California, show that the internal architecture of earthquake faults is heterogeneous at a variety of scales. Field and microstructural observations are used to describe in detail the architecture of two pseudotachylyte-bearing fault …

Mult-Scale Jet/Front Interactions that Organize Typical Cloud Seeding Environments in the Sierra Nevada
… water above the complex terrain over the Central Sierra Nevada Mountains. This environment favors cloud seeding which can enhance the local orographic precipitation. Most of the time, however, water vapor is not that significant and therefore forecasting cloud seeding conditions is quite …

Growth responses of selected plant species on serpentine soil of the western Sierra Nevada foothills
… on serpentine and non-serpentine soils from the Sierra Nevada foothills and the adjacent area. Various measurements were taken at intervals during the life cycle to determine the comparative growth patterns on different types of soil. These measurements indicate the degree of serpentine tolerance …

Disentangling how climate change and forest management alter fuels and fire regimes in Sierra Nevada forests
… the atmosphere every year. In the California Sierra Nevada, wildfires have become more extreme in response to both climate change and historical fire suppression. To address these changes, forest managers use fuel treatments to reduce fire hazard, return fire regimes to their historical range …

Improving Snow Deposition Magnitude and Heterogeneity Using Historic Snow Patterns in the California, USA, Sierra Nevada
… of repeatable snow patterns in the California Sierra Nevada using an unprecedented collection of ground-based, airborne, and satellite-based snow observations. We investigated how historic information about snow distribution and real-time snowpack observations could be combined to infer snow …

Wildfires for resilience in California’s Sierra Nevada: fine-scale assessment at regional scales with airborne lidar
… and dry forest ecosystems in California’s Sierra Nevada. For chapter one, I developed a geospatial dataset delineating sites where a frequent and low- to moderate-severity fire regime has begun to reestablish in the modern era, then used lidar to compare multi-scale structural patterns …

Opportunities and Constraints of Sierra Nevada Meadow Restoration for the Mountain Yellow-Legged Frog Species Complex
… considered the most abundant vertebrate in the Sierra Nevada, has suffered dramatic population declines in recent decades, and implications of their decline include biodiversity impacts throughout this region. Specifically, the distribution of MYLF has severely contracted within their geographic …

Conservation Genetics of Narrowly Distributed Annual, <em>Erythranthe discolor </em>(Phrymaceae), in the Southern Sierra Nevada
… endemic to California and occurs in the southern Sierra Nevada in Kern and Tulare counties with known flower color polymorphisms. There are 133 known occurrences of E. discolor with the core of its range found in the Piute Mountains in Kern County, managed by Sequoia National Forest. The Piute …

Processes and rates of arc crust growth and differentiation in the Southern Sierra Nevada crustal section
… the exposed crustal section in the southernmost Sierra Nevada Batholith, California. This section exposes plutons that were emplaced at pressures ranging from 3-10 kbars, as well as metamorphic wall rocks. Chapters 1 and 2 represent focused studies of the Bear Valley Intrusive Suite (BVIS), the …

Escaping the extinction vortex: identifying factors affecting population performance and recovery in endangered Sierra Nevada bighorn sheep
… guide recovery efforts for federally endangered Sierra Nevada bighorn sheep, the rarest subspecies of mountain sheep in North America. I initiated a combination of demographic, habitat and genetic analyses to identify the stochastic and deterministic factors limiting the recovery of this …
