The Nanga Parbat-Haramosh massif (NPHM) is a unique structural
and topographic high in the northwestern corner of the Himalayan
convergence zone. Previously, the NPHM was thought to be bounded by
the MMT, a thrust along which the Kohistan-Ladakh island arc was
obducted onto the northern margin of fridia. This study...

Variable ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects propagating up to higher trophic levels. Our goal was to better understand how varying ocean conditions influence diets and niche overlap among a suite of low- to mid trophic level predators. We studied the...

The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

Ecological niche theory holds that species distributions are shaped by a large and complex suite of interacting factors. Species distribution models (SDMs) are increasingly used to describe species’ niches and predict the effects of future environmental change, including climate change. Currently, SDMs often fail to capture the complexity of species’...

The terrestrial biosphere sequesters up to a
third of annual anthropogenic carbon dioxide emissions,
offsetting a substantial portion of greenhouse
gas forcing of the climate system. Although a number
of factors are responsible for this terrestrial carbon
sink, atmospheric nitrogen deposition contributes by
enhancing tree productivity and promoting carbon
storage...

Hydrology is a fundamental factor influencing ecosystem dynamics, life-history strategies, and diversity patterns in running-water habitats. However, it remains unclear how hydrology may structure the taxonomic and functional composition of communities, especially in systems with high spatiotemporal variability in flow. We examined invertebrate diversity from 7 desert streams in the...

This essay provides a snapshot of sustainability and acceptability of wave energy and eight other electricity-generating energy sources in Oregon. Since “sustainability” is an important point of view in decision-making, the paper is centered around the concept. Although there is no consensus on the definition of sustainability in the academic...
The Mitchell inlier in north-central Oregon contains the largest exposure of Cretaceous marine sedimentary rocks in this region. Nearly 9,000 ft of Albian-Cenamanian rocks are exposed along the flanks of the Mitchell anticline. The Cretaceous section rests unconformably overlain by Tertiary volcanic rocks. The Cretaceous rocks have previously been divided...
