Influence of root architectural development on Douglas-fir seedling morphology and physiology

Creator:: Jacobs, Douglass Frederick
Abstract:: A series of experiments were established to gain a better understanding of the extent to which Douglas-fir seeding root architecture may be manipulated and subsequent influences on seedling morphological and physiological development. The incorporation of amendments into nursery soils changed root architecture to some degree, but did not produce large...

Development of Douglas-fir seedling root architecture in response to localized nutrient supply

Creator:: Jacobs, Douglass Frederick, Rose, Robin, and Haase, Diane L.
Abstract:: Three months following sowing, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were transplanted into pots with controlled-release fertilizer (CRF) applied at rates of 0, 8, 16, and 24 g/2200 cm3 soil as a single uniform layer beneath the root system. Seedlings were destructively harvested periodically, and roots were divided into vertical...

Universal design standards for single-family housing

Creator:: Wolford, Nancy L.
Abstract:: The purpose of this study was to determine the level of awareness and use of selected universal design features and products in single-family housing by Oregon housing contractors. Also researched were barriers and incentives to use as well as the position and opinions of these housing contractors on the viability...

Tropical tropopause layer

Creator:: Fueglistaler, S., Desller, A.E., Dunkerton, T.J., Folkins, I., Fu, Q., and Mote, Philip W.
Abstract:: Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp ‘‘tropopause.’’ In the tropics, this layer is often called the ‘‘tropical tropopause layer’’ (TTL). We present an overview of observations in the TTL and discuss...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Habitat use by snag-associated species : a bibliography for species occurring in Oregon and Washington

Creator:: Weikel, Jennifer M., Hayes, John P. (John Parker), and Oregon State University. Forest Research Laboratory
Abstract:: Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...

Considerations for the use of ecological indicators in restoration effectiveness evaluation

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: This report focuses on the use of ecological indicators to evaluate ecological restoration effectiveness, particularly restoration aimed at salmonid recovery and watershed restoration efforts under the Oregon Plan for Salmon and Watersheds. Part 1 addresses conceptual issues including how indicators can be linked to monitoring, how conceptual models can be...
