Global climate change is expected to exaggerate the severity of floods and droughts and increase the frequency of extreme streamflow events in the Midwestern United States. Managing these projected impacts poses a major challenge for water resources, conservation, and land use management. Wetlands have been considered as a conservation strategy...
The boundary between ice and basalt on Earth is an analog for some near-surface environments of Mars. We investigated neutrophilic iron-oxidizing microorganisms from the basalt-ice interface in a lava tube from the Oregon Cascades with perennial ice. One of the isolates (Pseudomonas sp. HerB) can use ferrous iron Fe(II) from...

Abstract
The boundary between ice and basalt on Earth is an analogue
The boundary between ice and basalt on Earth is an analog for some near-surface environments of Mars. We investigated neutrophilic iron-oxidizing microorganisms from the basalt-ice interface in a lava tube from the Oregon Cascades with perennial ice. One of the isolates (Pseudomonas sp. HerB) can use ferrous iron Fe(II) from...
Wetland habitats are disappearing at an alarming rate and research is finding that establishment and creation of wetland habitat is generally unsuccessful. Typical mitigation strategies in the past have created multiple small isolated wetlands with little functioning habitat. Within Washington State, guidance and research recommends utilizing mitigation banks to compensate...
Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of
ecological understanding. This work is my attempt at communicating both of these, in relation
to three questions about our understanding of the structure and dynamics of biological diversity.
These questions focus on a) advancing our understanding of...
We isolated a methanogen from deep in the sediments of the Nankai Trough off the eastern coast of Japan.
At the sampling site, the water was 950 m deep and the sediment core was collected at 247 m below the sediment
surface. The isolated methanogen was named Nankai-1. Cells of...
Coarse woody debris (CWD, comprised of snags and downed logs) is an important component of the structure and function of forest ecosystems, one which both influences the availability of fuel for wildfires and can be a result of wildfires. We studied snag persistence, and changes in mass of CWD in...
This paper focuses on investigating (a) how landowner tenure and attitudes of farming communities affect the preference of individual conservation practices in agricultural watersheds, (b) how spatial distribution of landowner tenure affects the spatial optimization of conservation practices on a watershed scale, and (c) how the different attitudes and preferences...
Methane (CH₄) is a valuable fuel, constituting 70–95% of natural gas, and a potent
greenhouse gas. Release of CH₄ into the atmosphere contributes to climate change.
Biological CH₄ production or methanogenesis is mostly performed by methanogens, a
group of strictly anaerobic archaea. The direct substrates for methanogenesis are H₂
plus...
