The extent and severity of wildfires in forested regions are increasing throughout many regions on the planet, including western North America. High-severity wildfires directly affect soils and vegetation by altering soil hydraulic properties, reducing soil organic matter, exporting carbon and nitrogen, and killing trees and understory vegetation. These impacts can...
The purpose of this study was to investigate the effects of wildfire on soil hydraulic properties of forested hillslopes. The study site was located within the Stouts Creek wildfire, which burned approximately 10,705 ha of forest in southwestern Oregon in summer 2015. Three soil hydraulic properties (soil moisture, unsaturated hydraulic...
Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...
The primary purpose of this study was to determine if inservicing Agriculture Science and Technology (AST) teachers over a new curriculum, resulted in increased student achievement. Specific objectives were to: 1) determine the subject areas (lessons) for a curriculum for teaching Integrated Pest Management (IPM); 2) develop a curriculum for...

Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...
The purposes of this study were to: 1) determine in what ways incorporating active engagement into a traditional lecture chemistry course contributed to students' science identity and their motivation to learn the science, and 2) determine how the development of a science identity could be measured through the use of...
Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...
These studies focused on maximizing the nutrition and safety of raw whole
muscle beef while minimizing quality and shelf-life alteration. The first study used
response surface methodology to predict fluid loss from injected beef strip loins and
steaks as influenced by levels of salt and sodium phosphates (SP) in the...
In a seminal paper published in 1982, scientist have warned that humanity was pushing earth’s ecosystems beyond their capacities to support the web of life. One response to the concern was outlined by NASA with its vision for advanced fixed wing transport aircraft to be environmentally compatible and have revolutionary...
