The development and maintenance of stream community structure and organization

Creator:: Wevers, Mary Jo
Abstract:: The goal of this study was to better understand stream communities through a perspective that might make their structure, organization, and development more understandable. This goal was approached through the following objectives: 1. To determine the assemblages of stream organisms and define subsystems within a stream community. 2. To explain...

A systems classification of watersheds and streams

Creator:: McCullough, Dale A.
Abstract:: Adequate management and scientific investigation of ecosystems depends on classification of landscape systems based on all significant bio-physical and associated cultural properties. The present classification is a hierarchical systems design that can be modeled in terms of a natural system interacting with its level-specific environment. A watershed system in this...

Model III : a sequential approach to joint optimization of the stand treatment and forest level harvest scheduling problem

Creator:: Barber, Richard L.
Abstract:: Harvest scheduling and stand level optimization have generally been regarded as separable problems. Some studies have attempted to jointly optimize a wide range of stand treatments and a forest wide harvest schedule using combinations of mathematical programming techniques. The mathematical programming forest level techniques presume perfect information on production, costs...

Multiple pest suppression with cover crops in strawberry

Creator:: Datta, Braja Bandhu
Abstract:: The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

Consumer and descriptive panel analysis of commercial yogurts

Creator:: Barnes, Debbie L.
Abstract:: A consumer and a trained descriptive panel was utilized to determine liking ratings and flavor profiles, respectively, for commercial brands of pre-stirred yogurt. Once the consumer and descriptive panel data was collected, the data was combined to determine the interrelationship of these two sets of data and to determine the...

Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens

Creator:: Mattox, Clint M.
Abstract:: Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...

The role of soil-water depletion and plant-moisture stress in soil classification and cambial activity of Douglas-fir

Creator:: Thomas, Byron R.
Abstract:: Relationships between soil-water stress and plant-moisture stress were studied with respect to soil classification and cambial activity in Douglas-fir. The study sites were forested with Douglas-fir and located in McDonald Forest and near Marys Peak in the Oregon Coast Range. Soil-water depletion was followed by the use of gypsum blocks...

Combustion mechanisms in wood fired boilers

Creator:: Tuttle, Kenneth Lewis
Abstract:: A program of research has been established at Oregon State University to study wood residue combustion using an experimental spreader-stoker combustor. This research was conducted to increase the understanding of combustion occurring in wood fired boilers. Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial experiments were conducted varying...
