A step-by-step guide to riparian tree and shrub planting in the Willamette Valley. Provides information on project planning, plant materials, site preparation, planting techniques, site maintenance, and monitoring and evaluation. Intended to help landowners, watershed council members, agency personnel, and others communicate about, plan, and implement woodland plantings near streams...
Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. We examined how site environment and initial substrate quality influence decomposition and nitrogen (N) dynamics of multiple litter types. A 2.5-year decomposition study was installed in the Oregon Coast Range and West Cascades using ¹⁵N-labeled litter from Acer macrophyllum,...
This dissertation deals with end and side launching of marine
vessels. Its object is three-fold: first, to review several successful
techniques of launching and to describe the problems involved;
second, to derive and explain the calculations needed for assuring a
successful launching; and third, to propose several computer programs
which...
This publication is offered as a reference to Integrated Pest Management (IPM) resources available to Oregon growers. It highlights university, federal, state, and private services and resources that provide support to growers in the implementation of IPM programs. The Guide consists of five sections: • An introduction to the National...
A significant challenge for energy storage technologies is to realize battery-level energy density and capacitor-level durability and
power density in one device. By introducing an electrolyte composed of an anionic catholyte and a cationic anolyte into a symmetric
carbon-based supercapacitor configuration, a hybrid electrochemical battery-supercapacitor system using soluble redox species...

Human activity has been shown to considerably affect the spread of dangerous pests and pathogens worldwide. Therefore,
strict regulations of international trade exist for particularly harmful pathogenic organisms. Phytophthora plurivora, which is
not subject to regulations, is a plant pathogen frequently found on a broad range of host species, both...

Seed germination sensu stricto is defined as the physiological events before the radicle tip ruptures the covering tissues. The ability of the radicle to elongate (or germination potential) is observed in developing embryos prior to completion of seed maturation. When embryos at early developmental stages, such as globular, heart, torpedo...
Freshwater ecosystems in the mid- to
upper-latitudes of the northern hemisphere are particularly
vulnerable to the impact of climate change as
slight changes in air temperature can alter the form,
timing, and magnitude of precipitation and consequent
influence of snowmelt on streamflow dynamics. Here,
we examine the effects of hydro-climate,...

The German hop Hallertauer, hallertauer is highly
valued because of its "noble aroma", but it has a very low
yield when cultivated in the U.S. Two new crosses of
Hallertauer, U.S.D.A. 21455 and 21459, have high yields
and promising aroma characteristics.
In order to predict sensory properties of beers as...
Polyandry is a source of sexual conflict and males often try to limit female promiscuity. Consequently, male manipulation of receptivity via antiaphrodisiacs and copulatory plugs that prevent female remating can be a source of sexual conflict. This sexual conflict may be intensified when females must remate for fertility insurance. Male...
