Disposal of chlorinated hydrocarbons is a major environmental concern due to the lack of a satisfactory means of safe remediation at all contaminated locations. Current technologies rely primarily on incineration, a process that can lead to dangerous byproducts such as dioxin. If the chlorine substituent can be removed prior to...
Before 2002, almost all of the approximately 40,000 acres of land in the Wood River Valley, Oregon were used for intensive, flood-irrigated summer cattle grazing, as it had been for over 100 years. Conservation activity in the valley was limited to a couple of wealthy landowners. But a year after...

The composition of the continental crust is closely tied to subduction zone magmatism. Elevated oxygen fugacity (fO₂) plays a central role in fostering crystallization of oxide minerals and thereby aids in generating the calc-alkaline trend of iron depletion that characterizes the continents. Along continental margins, arc magmas erupt through continental...

Overfished species of rockfish, Sebastes spp., from the Northeast Pacific experience high bycatch mortality because of ‘barotrauma’, a condition induced from the rapid change in pressure during capture. Field experiments show that it may be possible for rockfish to recover from barotrauma if quickly recompressed; however, no work has followed...
Hop (Humulus lupulus L.) cones are used extensively in beer brewing to enhance flavor and impart bittering. Verifying hops cultivar identity has traditionally been accomplished by morphological characteristics or a chemical analysis of lupulin glands but these traits may vary according to environmental influences. The objective of this research was...
Predators sometimes provide biotic resistance against invasions by nonnative prey. Understanding and predicting the strength of biotic resistance remains a key challenge in invasion biology. A predator's functional response to nonnative prey may predict whether a predator can provide biotic resistance against nonnative prey at different prey densities. Surprisingly, functional...
