Listeria monocytogenes is the third most deadly foodborne pathogen in the United States. The young and elderly, as well as pregnant and immunocompromised people are the population most susceptible to serious illness and death from listeriosis infections.
Unlike most foodborne pathogens, L. monocytogenes does not live a solely enteric lifestyle....
Reproductively and geographically isolated populations of predators may be synchronized by a phenomenon known as the Moran effect—specifically if they exhibit common responses to external processes, such as climate, density dependence (parasites, disease), or prey. Prey has the ability to synchronize predators if geographically isolated predator populations target the same...

Fault zones are potential paths for release of radioactive nuclides from radioactive-waste
repositories in granitic rock. This research considers detailed maps of en echelon fault zones
at two sites in southern Sweden, as a basis for analyses of how their internal geometry can
influence groundwater flow and transport of radioactive...

Tidal wetlands are a powerful carbon sink. They can sequester an order of magnitude
more carbon than any other type of wetland system, and emit only negligible amounts

Between 2007 and 2009, researchers from Green Point Consulting, Oregon State University, and the South Slough National Estuarine Research Reserve collected data on ecological and physical characteristics at five high-quality “least disturbed” tidal wetland sites in four Oregon estuaries.
The reference sites included in this project are (1) Blind Slough...

Diatoms are a ubiquitous group of plankton responsible for 20-40% of oceanic
primary production, and a higher fraction of organic matter export to the ocean
interior. Diatoms actively transport dissolved inorganic silicon into their cells, and
through the process of silicification (i.e. biogenic silica production) they build tough
and intricate...

This is an integrated assessment across terrestrial, freshwater, and coastal marine realms. It includes the coast range of Oregon and Washington as well as Vancouver Island in British Columbia. The marine portion only includes the coastline and shallow subtidal; the next iteration will include the offshore component.
Nanotechnology is of increasing significance. Curation of nanomaterial data into electronic databases offers opportunities to better understand and predict nanomaterials’ behaviour. This supports innovation in, and regulation of, nanotechnology. It is commonly understood that curated data need to be sufficiently complete and of sufficient quality to serve their intended purpose....

Tile drainage increases aeration in the root zone of poorly drained soils by
accelerating water movement from the subsurface. Water movement is the main agent
of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by
transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The
detection frequency...

Statistical summaries of streamflow data at 212 stream-gaging sites
are presented in this report to aid in appraising the hydrology of river
basins in Western Oregon. Records for 21 gaging stations were compiled
into separate periods owing to changes in regulation during the period
of data collection. The periods before...
