Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...
Intraexciton transitions in semiconductor quantum wells are modulated by strong and tunable few-cycle terahertz pulses. Time-resolved terahertz-pump and optical-probe measurements demonstrate that the 1s heavy-hole and light-hole exciton resonances undergo large-amplitude spectral modulations when the terahertz radiation is tuned near the 1s–2p intraexciton transition. The strong nonlinear optical transients exhibit...
To characterize the mechanism through which myosin XI-K attaches to its principal endomembrane cargo, a yeast two-hybrid library of Arabidopsis thaliana cDNAs was screened using the myosin cargo binding domain as bait. This screen identified two previously uncharacterized transmembrane proteins (hereinafter myosin binding proteins or MyoB1/2) that share a myosin...
Interactions of few-cycle terahertz pulses with the induced optical polarization in a quantum-well microcavity reveal that the lower and higher exciton-polariton modes together with the optically forbidden 2p-exciton state form a unique Lambda-type three-level system. Pronounced nonlinearities are observed via time-resolved strong-terahertz and weak-optical excitation spectroscopy and explained with a...
Plants possess two myosin classes, VIII and XI. The myosins XI are implicated in organelle transport, filamentous actin
organization, and cell and plant growth. Due to the large size of myosin gene families, knowledge of these molecular motors
remains patchy. Using deep transcriptome sequencing and bioinformatics, we systematically investigated myosin...

Image-based dietary intake assessment (IBDIA) is a new way by which the accuracy of dietary assessment can be improved through the use of digital images of food. The ability of nutrition and dietetics students and interns to accurately interpret images for diet intake assessment is currently unknown. An online survey...
Restoration of invaded aridlands is required to reduce the exorbitant ecological and monetary losses related to noxious weeds. An understanding of how reduced and increased levels of soil N and P influence interference between medusahead and squirreltail is imperative to understanding how squirreltail may be used in restoration of medusahead...
Bicyclists are one of the highest and most vulnerable road users. This is due to the higher likelihood of being seriously injured when involved in a crash. This research seeks to understand two different behavioral interactions of an implemented facility user: the motorist (secondary user) and bicyclist (primary user). The...
Racial, ethnic and gender diversity have been long term topics of discussion in natural resources. Yet to date, there has not been a comprehensive review of the existing literature within the discourse of demographic diversity. Therefore, I conducted a systematic review of demographic diversity in the disciplines of forestry, fisheries,...
The two studies of this dissertation examined mothers' perspectives of nonresident fathers' involvement in low-income families. The overall goal of these studies was to gain a more comprehensive understanding of nonresident fathers' involvement and its effect on family well-being. In the first study I applied a relatively new methodology, zero-inflated...
