Invasive species in riparian forests are unique as their effects can transcend ecosystem boundaries via stream-riparian linkages. The green alder sawfly (Monsoma pulveratum) is an invasive wasp whose larvae are defoliating riparian thin-leaf alder (Alnus tenuifolia) stands across southcentral Alaska.

The opportunistic pathogen Pseudomonas aeruginosa possesses two LuxR-LuxI
type quorum-sensing systems that use diffusible acyl-homoserine lactone molecules to
autoinduce and coordinate expression of multiple virulence factors. We conducted a highthroughput
screen for mutants deficient in skim-milk proteolysis—a quorum-sensing
dependent phenotype—using a nonredundant transposon-insertion library representing
most nonessential genes in P....
In 1983, our research group took on the task of answering the question: What are the characteristics of available Pinot noir clones in Oregon? Our main resources in this effort were the OSU Mother Block and two cooperative clonal trials at Knudsen Erath (KE) and Five Mountain Vineyards( 5M). Information...
While the importance of international trade in fish products has long been recognized, international trade in fishing services (TIFS), involving harvesting, processing, transportation and marketing has received but little attention.

Large equine facilities are comprised of many different departments (areas) that are necessary for the proper care and maintenance of horses. The placement of departments is often inefficient due to the slow growth of equine facilities. As a result, facility layout becomes a crucial aspect requiring explicit consideration because mandatory...
