Benthic Habitat Mapping: eCognition Rule Set

Creator:: O’Neil-Dunne, Jarlath P. M., Parrish, Christopher E., and Dijkstra, Jennifer A.
Abstract:: This publication consists of a rule set for benthic habitat classification implemented in eCognition (Trimble Navigation Limited). The details of the procedure are described in Parrish et al., 2016: http://www.jcronline.org/doi/abs/10.2112/SI76-017. The input to the classification consists of high-resolution true color orthophotos, seafloor DEMs from topobathymetric lidar, and gridded lidar reflectance...

Poly- and perfluorinated alkyl substance release from landfills and landfill model reactors

Creator:: Allred, Brent McKay
Abstract:: Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...

Relative heat sensitivities and the potential for soil solarization to remediate nursery beds infested with Phytophthora spp.

Creator:: Weidman, Clara Suzanne
Abstract:: Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...

Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

Analytical method development for the identification, detection, and quantification of emerging environmental contaminants in complex matrices

Creator:: Place, Benjamin J.
Abstract:: The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...

Assessing Chemical Dispersants Used During the Deepwater Horizon Oil Spill : Method Innovation and Application

Creator:: Perkins, Matt J.
Abstract:: Large quantities of the chemical oil dispersant Corexit were applied in the Gulf of Mexico (Gulf) in response to the Deepwater Horizon oil spill. Large data gaps regarding the potential transport, persistence and impact of Corexit in the Gulf existed at the time of the emergency response. Analytical methods for...

Addressing wastewater epidemiology limitations with the use of dynamic population surrogates, complementary urinalyses and in-situ experiments

Creator:: Brewer, Alex J.
Abstract:: Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...

Identification of novel immune molecular pathways and response markers to OmniGen-AF® supplementation in a rat model

Creator:: Branson, Jennifer A.
Abstract:: OmniGen-AF® (OG; Prince Agri Products, Inc., Quincy, IL) is a feed additive containing brewers dehydrated yeast and B-vitamins that supports immune function in ruminant livestock. Targeted profiling of immune-associated genes in whole blood is an effective platform for identification of a) novel molecular pathways and b) immune response markers to...

The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

Creator:: Stamm, Elizabeth A.
Abstract:: Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

Residents’ drivers and barriers to participation in the Backyard Habitat Certification Program : Study of socio-ecological factors in Madison South neighborhood in NE Portland

Creator:: Powel, Jinnet
Abstract:: As urban development fractures and reduces available habitat for birds and other wildlife, conservationists are increasing pursuing strategies to improve the habitat value of privately owned yards in and around cities. The Backyard Habitat Certification Program is a collaborative effort between the Portland Audubon Society and the Columbia Land Trust...
