Illuminating Patterns in Dark Microbial Matter: Diversity and Distribution of Fungi and Actinobacteria in Deep-sea Methane Seep Sediments

Creator:: Ardor Bellucci, Lila
Abstract:: Fungi and Actinobacteria are essential actors in global biogeochemical cycles of carbon and nutrients, and have both been recently appreciated for their roles in marine ecosystems. However, the diversity and distribution of these ubiquitous, but low-abundance microbes in deep-sea habitats remains poorly understood, particularly in chemosynthetic habitats such as methane...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Shell Boring Polychaetes and the Oregon Oyster Aquaculture Industry: Spatial Distribution, Regulatory Actions, and Stakeholder Engagement

Creator:: Considine, Megan E.
Abstract:: Shell-boring polychaetes pose economic risks for oyster aquaculture industries as they reduce the aesthetic quality of oyster products by creating unsightly mud-filled blisters on the inside of the shell. Recently there has been a reported uptick in infested oysters on commercial farms along the west coast of the US, which...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Investing upstream : a social-ecological systems perspective on water utility investments in ecosystem services

Creator:: Bennett, Drew E.
Abstract:: The concept of ecosystem services broadens perspectives on nature to include not only intrinsic value but also the utilitarian value it provides to society. Viewing nature through this lens informs our understanding of how particular ecological processes benefit different actors. In this research, I examine how water utilities in the...

An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

Creator:: Costello, Denise H.
Abstract:: The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

The late holocene atmospheric methane budget reconstructed from ice cores

Creator:: Mitchell, Logan E.
Abstract:: Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

Pillaging Bloodwood: An Exploratory Examination of Illegal Deforestation in Guinea-Bissau Through Forest Disturbance Algorithms and Unsupervised Clustering Techniques

Creator:: Walters, Alexander E.
Abstract:: Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:: Moore, Nicole E.
Abstract:: Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...
