Tocopherols are plant secondary metabolites that are known collectively as
vitamin E. Tocopherol compounds act as potent antioxidants by quenching free
radicals and protecting fatty acids from oxidative damage. In humans (in vivo)
tocopherols protect membrane lipids from breaking down, while in oils (in vitro)
tocopherols protect fatty acids from...
This greenhouse study evaluates the influence of separately and
simultaneously imposed water stress, western spruce budworm (Choristorneura
occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria
ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis
(Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and
allocation...
A laboratory method for evaluating wood preservatives should provide in a comparatively short time an integrated measure of the relative permanence and fungus-inhibiting capacity of a product. There is as yet no generally acceptable laboratory method of this type. Systematic service records serve to bolster the reputation of established preservatives....
This compendium contains listings of ongoing and recently completed research and administrative studies conducted in the Oregon Coast Range in the areas of fisheries, forestry, soils/hydrology, and wildlife. To assemble this compendium, requests for information were sent to about 145 individuals from various agencies, companies, and universities. Individuals and agencies...
Questions: Are exotic plant species favoured by non-native ungulate herbivores and disadvantaged by native herbivores in forested rangelands? Do the impacts of ungulates on exotic vs native plants depend on forest management activities such as prescribed fire and stand thinning?
Location: Northeastern Oregon, USA.
Methods: We recorded changes in richness...
