A publication containing advice on a wide range of gardening topics, including composting, container gardens, fall/winter gardens, fertilizing, insect pests, plant diseases, planting guidelines, raised beds, site selection, slugs, soil improvement, tilling, warm-season crops, watering, and weeds. Includes regional tips for various parts of Oregon.
The purpose of this report is to characterize the December 2007 storm and long-term storm variability along the Oregon and Washington coast, present the results of a rapid assessment of randomly selected OWEB restoration projects (restoration activities including large wood placement, fish passage, and riparian planting), and based on the...

Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

AN ABSTRACT OF THE DISSERTATION OF
Mark A. Albins for
Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
All ecosystems are subjected to chronic disturbances, such as harvest, pollution, and climate change. The capacity to forecast how species respond to such press perturbations is limited by our imprecise knowledge of pairwise species interaction strengths and the many direct and indirect pathways along which perturbations can propagate between species....

Cable yarding systems (also sometimes known as skyline yarding systems) are a versatile means for transporting materials in mountainous terrain in situations that do not allow for conventional harvesting methods such as ground skidding or shovel-logging. Adequate ground anchors are necessary for the safe operation of cable yarding systems. Anchored...

Forests play a critical role sequestering atmospheric carbon dioxide, partially offsetting greenhouse gas emissions, and thereby mitigating climate change. Forest management, natural disturbances, and the fate of carbon in wood products strongly influence carbon sequestration and emissions in the forest sector. Government policies, carbon offset and trading programs, and sustainable...

Pseudomonas protegens strain Pf-5 is a rhizosphere bacterium that suppresses soilborne plant diseases and produces at least seven different secondary metabolites with antifungal properties. We derived mutants of Pf-5 with single and multiple mutations in biosynthesis genes for seven antifungal metabolites: 2,4-diacetylphoroglucinol (DAPG), pyrrolnitrin, pyoluteorin, hydrogen cyanide, rhizoxin, orfamide A,...

The ability of plants and microorganisms to take up organic nitrogen in the form of free amino acids and oligopeptides has received increasing attention over the last two decades, yet the mechanisms for the formation of such compounds in soil environments remain poorly understood. We used Nuclear Magnetic Resonance (NMR)...

Pseudomonas fluorescens WH6 secretes a germination-arrest factor (GAF) that we have
identified previously as 4-formylaminooxyvinylglycine. GAF irreversibly inhibits germination of the
seeds of numerous grassy weeds and selectively inhibits growth of the bacterial plant pathogen
Erwinia amylovora. WH6-3, a mutant that has lost the ability to produce GAF, contains a...
