Hydrophobicity, Anion Exchange, and Phytoaccumulation of Per- and Polyfluoroalkyl Substances (PFAS): Retention and Remediation

Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...

Effects of Step-Wise Acclimation versus Shock Loading on the Performance of Anaerobic Co-Digestion of Fats, Oils, and Greases

Creator:: Berninghaus, Ashley E.
Abstract:: Anaerobic digestion is a microbially mediated process by which organic matter is decomposed in the absence of oxygen. The end products of anaerobic digestion include treated sludge and biogas, a mixture of methane and carbon dioxide, which can be recovered and used for energy generation. The majority of wastewater treatment...

New Environmental Governance on the Range : Voluntary Conservation to Preclude an Endangered Species Act Listing?

Creator:: Wollstein, Katherine L.
Abstract:: Natural resource challenges in the American West feature a suite of actors and processes operating at different spatial and political scales, and crossing several administrative jurisdictions. I applied concepts of new environmental governance to Oregon’s greater sage-grouse (Centrocercus urophasianus) conservation strategy, focusing, in particular, on features of voluntary conservation arrangements...

The role of keratinocytic RXRα in regulating melanocyte homeostasis and carcinogen induced melanomagenesis, The role of keratinocytic RXR[alpha] in regulating melanocyte homeostasis and carcinogen induced melanomagenesis

Creator:: Hyter, Stephen D.
Abstract:: Cutaneous melanoma remains the deadliest form of skin cancer, with a diagnosis of metastasis indicating a median survival rate of less than a year. Solar ultraviolet (UV) radiation, especially childhood sun exposure, is an important etiological risk factor of melanoma. Previous studies determined that mice selectively lacking the nuclear hormone...

Anaerobic Co-Digestion of Municipal Sludge and Fats, Oils, and Greases: Effects on Digester Performance and Microbial Community Dynamics

Creator:: Berninghaus, Ashley E.
Abstract:: The natural production of methane via anaerobic digestion (AD) is facilitated by a complex community of microorganisms, primarily bacteria and archaea, referred to as the AD microbiome. AD is growing in prominence as a solution to the disposal of food waste, sewage sludge, and the organic fraction of municipal solid...

Evaluating balance and strength of older women in exercise programs

Creator:: Dinger, Melanie
Abstract:: Falls are a common problem among older adults, including those who are relatively healthy and living independently. Exercise has been recommended as an intervention to reduce falls by slowing and/or reversing age-related declines in balance, strength, and mobility. However, it remains unclear which types or combinations of programs are most...

Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

Greater sage-grouse population trends: An analysis of lek count databases 1965-2015

Creator:: Western Association of Fish and Wildlife Agencies
Abstract:: Counts of males attending leks in the spring have been the primary means employed by states to monitor status of greater sage-grouse (Centrocercus urophansianus) populations for over 75 years. Despite limitations and potential biases, lek count data remain the only long-term, range-wide dataset available for evaluating trends in sage-grouse populations....

The Role of Trees and Thermal Refugia in Greater Sage-Grouse Brood Habitat Selection

Creator:: Dungannon, Tyler D.
Abstract:: It is well documented that greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) populations have been in decline throughout their range in the western United States. Currently, sage-grouse occupy approximately 56% of their historic distribution prior to European settlement. Numerous factors have been cited as potential causes for declining productivity and contraction...
