A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive
film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating
magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing
acoustic waves, respectively. The magnetization pattern is size-tunable,...
The Pacific red lionfish has recently invaded Western Atlantic and Caribbean coral reefs, and may become one of the most ecologically harmful marine fish introductions to date. Lionfish possess a broad suite of traits that makes them particularly successful invaders and strong negative interactors with native fauna, including defensive venomous...
BACKGROUND: Workers onboard freezer-trawl (FT) and freezer-longline (FL) vessels in Alaska may be at high risk for fatal and non-fatal injuries. METHODS: Traumatic occupational injuries onboard vessels in the FT and FL fleets were identified through two government data sources. RESULTS: The annual risk of fatal injuries was 125 per...

Innovativeness can help companies differentiate themselves, with the ultimate goal of securing survival and improving performance. Modern theories in organizational behavior look at innovation as something that starts with individual creativity but that is also affected by the work environment. Using one broad industry sector, the US forest products industry,...

Breast-high stem sections were sampled from 56 western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees growing in 15 plots representing a wide range of tree and site conditions in northwestern Oregon. Growth and wood density traits of individual rings were measured via X-ray densitometry, and relationships of ring density and its...
The Oregon Multicultural Archives (OMA) at Oregon State University (OSU) is dedicated to preserving and making accessible the histories of traditionally under-represented groups. OMA curator Natalia Fernández and Tiah Edmunson-Morton, the OSU Libraries’ Instruction and Outreach Archivist, highlight three OMA collections that reflect the impact women of color have had...
We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic
cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the
opportunity to examine the cascading effects of carnivore–herbivore interactions...
Like most ecological communities, aspen (Populus tremuloides) forests are influenced by a synergy of bottom-up (resources-driven) and top-down (predator-driven) processes. Since the 1920s, ecologists have observed the decline of many aspen communities throughout the Intermountain West. The extent and possible drivers of this decline are topics of much recent scientific...
Using spatial autocorrelation analysis, we
examined the within-population genetic structure of
Rhizopogon vinicolor and R. vesiculosus, two hypogeous
ectomycorrhizal (EM) species that are sympatric
sister taxa known to differ in their clonal structure.
We collected 121 sporocarps and 482 tuberculate EM
of both species from a 20 ha forest stand...
