Examining ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

Creator:: Garcia, Maria Osuna
Abstract:: Background information is presented that provides historical perspectives on the field of mycology in the Pacific Northwest and its role in forest management. The series of events and decisions that have led to previous studies (or lack of studies) in the field also dictate the directions of current research. Culture,...

Interspecific carbon transfer in ectomycorrhizal tree species mixtures

Creator:: Simard, S. (Suzanne)
Abstract:: The overall goal of this study was to investigate influences of ectomycorrhizae (EM) and interspecific carbon transfer on seedling performance in species mixtures. The objectives were to: (I) determine the potential for EM to link paper birch and Douglas-fir, (ii) quantify gross and net interspecific carbon transfer, and (iii) evaluate...

Long-Term Stream Channel Response to a Large Flood in a Forested Mountain Watershed

Creator:: Goodman, Arianna C.
Abstract:: There is still scholarly debate on the impacts of large floods on the geomorphic evolution of mountain rivers. Understating the geomorphic effects of large flows in mountain rivers is challenging given the hydraulic complexity of these systems and the inherent unpredictability of large floods. Prior work has demonstrated that extreme...

Freshwater prokaryotic and eukaryotic diversity of the Oregon Willamette River basin

Creator:: Hoyle, Marilee C.
Abstract:: The wellbeing of the Willamette basin in Oregon depends on the river ecosystem’s microbial communities, which control primary production and the biological processing of nutrients, pollutants, and organic matter. Yet, only a few studies have investigated the diversity of the microbial communities of the Willamette basin. This paper examines how...

Why Anchor Forests? Exploring a Conceptual Framework for Tribal Leadership in Cross-boundary Forest Governance

Creator:: Jacobson, Meredith A.
Abstract:: In response to the increasing pace and scale of wildfire and forest health challenges, the Intertribal Timber Council (ITC) proposed the creation of “Anchor Forests,” where a tribe would convene surrounding landowners to collaboratively manage the entire landscape, across property boundaries. This emergent concept has sparked conversation but has not...

Enhancing Hydrogen Production using Single Chamber Microbial Electrolysis Cells by Tackling Hydrogen Scavengers

Creator:: Wang, Luguang
Abstract:: Biological hydrogen production from renewable feedstocks was reckoned as a promising method for sustainable energy production. Bioelectrochemical hydrogen production using microbial electrolysis cells (MECs) demonstrated superiorities over the conventional methods for hydrogen production. The introduction of the membrane-less single chamber design further improved the feasibility of MECs for practical application,...

“We All Live Downriver”: Environmental Justice and Community Resistance to the Pacific Connector Gas Pipeline and Jordan Cove Export Terminal in Southern Oregon

Creator:: Halleran, Patricia C.
Abstract:: Native America tribes and community members throughout Oregon have asserted a strong opposition to the fossil fuel industry’s attempt to expand railways, build pipelines, and construct refineries, holding facilities, and export terminals. Despite the limited presence of fossil fuel infrastructure in the state, however, the industry is actively pursuing permits...

Habitat Use and Ecological Interactions of Invasive Lionfish in the Bahamas

Creator:: Davis, Alexandra C. D.
Abstract:: Invasive species are a growing global economic and ecological problem. Invasive Indo-Pacific lionfish (Pterois spp.) are known to have extreme negative effects on coral-reef communities in the Bahamas, so understating their distribution within and among reefs, what limits their local movements, and the effects they have on native prey species...

Introducing and validating a high-throughput bud break sensor

Creator:: Kleinknecht, George J.
Abstract:: Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...

Canopy Effects on the Snow Hydrology of a Forested Mountain Environment in the Pacific Northwest, USA

Creator:: Roth, Travis R.
Abstract:: Rising global temperatures are having lasting effects on mountain snow environments in the form of diminishing snowpacks, shorter accumulation seasons, and shifts in meltwater timing. Seasonal snowpack is a vital source of water for natural and human systems. In the forested mountain landscapes of the Pacific Northwest seasonal snowmelt feeds...
