Pressurized liquid extraction (PLE) was evaluated as a method for extracting semivolatile organic compounds (SOCs) from air sampling media; including quartz fiber filter (QFF), polyurethane foam (PUF), and a polystyrene divinyl benzene copolymer (XAD-2). Hansen solubility parameter plots were used to aid in the PLE solvent selection in order to...

Gas hydrates, pervasive in continental margin sediments, are expected to release methane in
response to ocean warming, but the geographic range of dissociation and subsequent flux of methane to
the ocean are not well constrained. Sediment column thermal models based on observed water column
warming trends offshore Washington (USA) show...

Humpback whales (Megaptera novaeangliae), a mysticete with a cosmopolitan distribution, demonstrate
marked behavioural plasticity. Recent studies show evidence of social learning in the transmission of specific
population level traits ranging from complex singing to stereotyped prey capturing behaviour. Humpback
whales have been observed to employ group foraging techniques, however details...

We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction
margin of New Zealand, using thermomechanical numerical modelling informed by
wedge structure and porosities from multichannel seismic data. Calculated fluid sources are
input into an independent fluid-flow model to explore the key controls on overpressure generation

As a persistent organic contaminant, perfluorooctanesulphonic acid (PFOS) has been widely detected in the environment, wildlife, and humans. The present study revealed that zebrafish embryos exposed to 16 µM PFOS during a sensitive window of 48-96 hour post-fertilization (hpf) disrupted larval morphology at 120 hpf. Malformed zebrafish larvae were characterized...

Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists...

Sound and essential management practices, succinctly described, for maintaining a high quality, productive pasture and healthy livestock. The publication is primarily directed to eastern Oregon small acreage landowners.
Living on The Land — Managing Manure contains concise information on the basics of livestock manure management. Content includes handling, storage, composting, use, and ways to reduce negative effects on the environment. It particularly applies to the region east of the Cascade Mountains. Companion audio files include: The Scoop on...

Early-successional stages have been truncated and altered in many western U.S. forest landscapes by
planting conifers, controlling competing vegetation, suppressing fire, and focusing on maintaining late-seral
species and undisturbed riparian zones. Declining area of early-successional stages may be reducing
resilience and sustainability on landscapes that experience elevated disturbance related to...

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...

NW Rota-1 is a submarine volcano in the Mariana volcanic arc located ~100 km north of Guam.
Underwater explosive eruptions driven by magmatic gases were first witnessed there in 2004 and continued
until at least 2010. During a March 2010 expedition, visual observations documented continuous but
variable eruptive activity at...

We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked
common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions
of the water-column’s physical structure by implementing hierarchical models in a Bayesian
framework. This approach allowed us to propagate the uncertainty of the field observations
into the...
