Construction, Degradation, and Restoration of Wet Meadow Ecosystems in Semi-arid Landscapes, Northern Great Basin, USA

Creator:: Nash, Caroline S.
Abstract:: Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...

Counterfactual thinking applied to multiagent systems

Creator:: Zerbel, Nicholas
Abstract:: Multiagent approaches are well suited to designing autonomous solutions for systems that feature complex interactions between many individuals such as in autonomous traffic systems and multi-robot exploration systems. However, creating autonomous agents that function effectively in these systems is a challenging task. In these complex environments, agents need informative reward...

Providing Informative Feedback for Learning in Tightly Coupled Multiagent Domains

Creator:: Rockefeller, Golden C.
Abstract:: Autonomous agents that sense, decide, act, and coordinate effectively with each other are critical in many real-world domains such as autonomous driving, search and rescue missions, air traffic management, and underwater or deep space exploration. All such domains share a key difficulty: though high-level mission goals are clear to system...

Ecohydrological mediation of water budget partitioning and time scales of subsurface flow in a seasonally semi-arid grassland

Creator:: Pangle, Luke A.
Abstract:: Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

The cross-equatorial structure of tropical instability waves in sea surface height

Creator:: Lyman, John M.
Abstract:: A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Controls on Process and Form in Alluvial and Bedrock Meandering Rivers

Creator:: Zunka, John P. P.
Abstract:: Bedrock meandering rivers are sinuous channels that pair steep bedrock outside banks with lower gradient slip-off slopes on the inside of bends. These rivers have the potential to record information on climatic and tectonic “external” forcings in their morphology (e.g., longitudinal profiles, strath terraces, channel and valley dimensions). However, geology...
