The American Land Institute is proud to present this study, Oregon’s Public Investment in Conservation, Prosperity and Fairness. This is the first major study on a topic that has been largely overlooked in past and current discussions of land use law in Oregon: the nature and extent of property tax...

Little is known about mixing in the abyssal equatorial oceans in spite of its inferred importance for upwelling dense water. Here we present full-depth microstructure turbulence profiles obtained in the equatorial Pacific that show evidence for intense wind-generated abyssal mixing. Mixing was intensified over the bottom 700 m where the...

Sharp increases in the use of flammable plastics and electronic devices coupled with stricter fire safety requirements have promoted the heavy use of flame retardant chemicals. While flame retardant use has increased, a great deal of uncertainty surrounds their safety with some evidence showing toxicity and risk to human and...

In this report, we present future projections of climate and climate-related natural hazards in Benton County for the 2020s (2010–2039) and 2050s (2040–2069) relative to the 1971–2000 historical baseline. The projections are based on multiple global climate models for both a lower greenhouse gas emissions scenario (RCP 4.5) and a...
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...
Ecological niche models can be a useful tool to identify candidate reintroduction sites for endangered
species but have been infrequently used for this purpose. In this paper, we (1) develop activity-specific
ecological niche models (nesting, roosting, and feeding) for the critically endangered California condor
(Gymnogyps californianus) to aid in reintroduction...

The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting...

Marine sponges are vital components of benthic and coral reef ecosystems, providing
shelter and nutrition for many organisms. In addition, sponges act as an essential carbon
and nutrient link between the pelagic and benthic environment by filtering large quantities
of seawater. Many sponge species harbor a diverse microbial community (including...

Quaking aspens (Populus tremuloides Michx.) are found in diverse habitats throughout North America. While the biogeography of aspens' distribution has been documented, the drivers of the phenotypic diversity of aspen are still being explored. In our study, we examined differences in climate between northern and southwestern populations of aspen, finding...

We used multi-season occupancy analyses to model 2 fates of northern spotted owl territories in
relation to habitat amount, habitat fragmentation, and the presence of barred owls in Washington State,
USA, 1989–2005. Local colonization is the probability a territory unoccupied by a spotted owl in year i would
be occupied...
