The purpose of this inventory is to detail the state of environmental justice in the Mid- Willamette Valley in an up-to-date, centralized format. The inventory is based on information from various government sources, and a survey to gather first-person perspective to take a pulse of the wellbeing of our community....
Over 76 cities throughout the United States have already adopted policies to limit the expansion of natural gas, mainly through updates to city codes that ban natural gas infrastructure in new construction. Rising concern over the environmental and public health impacts of methane - a greenhouse gas with a much...
The Upper Sprague River Watershed (North and South Forks of the Sprague River) in south central Oregon provides important habitat for
salmonid species, including native bull trout (Salvelinus confluentus) and redband trout (Oncorhynchus mykiss ssp.). Concern over the loss of viable habitat for these species has increased due to reductions...
Using summertime housing transactions data of 3,309 parcels from multiple years in Eugene-Springfield, OR, we present a hedonic price model to estimate the influence of the urban heat island (UHI) effect on housing prices in this metropolitan area. By taking advantage of the inherent random nature of summertime weather observations,...
In August 2011, the final Upper Willamette River basin salmon and steelhead recovery plan was adopted by NOAA Fisheries and the Oregon Department of Fish and Wildlife. The plan highlights a variety of activities that need to be taken by both public and private entities in order to recover these...
Terahertz (THz) frequencies of the electromagnetic spectrum have been underutilized when compared to neighboring microwave and infrared frequencies, largely due to the difficulties controlling and detecting these fields. In a step toward gaining control over THz frequencies, my advisor Dr. Yun-Shik Lee’s group experimentally demonstrated optical-pulse THz-control over a plasmonic...
"In conclusion it may be said that kale is almost
a winter maintenance ration for swine, but when fed in
addition with a little grain or skim milk, good growths
will be made. Especially is this true of young pigs as
is denoted by the tables. Taking all in all,...
In 2020, Oregon suffered one of the worst wildfire seasons on record, with a higher percent of forest area burn, the destruction of residential areas, and the risk to human health. The level of intensity of these wildfires were due to the effects of climate change and Oregon wildfire seasons...
Feedback loops involving soil microorganisms can
regulate plant populations. Here, we hypothesize that microorganisms
are most likely to play a role in plant–soil feedback
loops when they possess an affinity for a particular plant and
the capacity to consistently affect the growth of that plant for
good or ill. We...

MIKE SHE is a fully distributed, physically-based hydrologic model that can simulate water movement over and under the Earth's surface. Evapotranspiration (ET) is one of the components of this model. MIKE SHE uses a modification of the Kristensen -Jensen (1975) method to calculate actual ET. This method is based on...
This report summarizes vegetation data collected in July 2015 in wet meadow and marshy habitats on the Double O Unit of Malheur National Wildlife Refuge (MNWR). Because vegetation sampled at the Double O was wetter and more alkaline than wet meadows sampled at the south end of the refuge in...
Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...
“Active carbon” is a rapidly cycling soil organic carbon (SOC) fraction that acts as an energy and nutrient source for the microbial community. Dilute permanganate oxidation has been used to measure an “active carbon” fraction with the assumption that permanganate oxidation mimics enzymatic decomposition. Permanganate oxidizable carbon (PoxC) has become...
