Photosynthetic response models for a terrestrial plant community

Creator:: Webb, Warren Lewis, 1935-
Abstract:: Photosynthetic response to light and temperature was modeled using data from a small red alder (Alnus rubra B. ) community growing in a controlled environment chamber linked to the computer. This new system controls air temperature, root temperature, and vapor pressure over a wide range, and both light intensity and...

The metabolic pathways and physiological effects of atrazine in Douglas-fir seedlings

Creator:: Peterson, Charles Adrian
Abstract:: Herbicides are being used as a tool by forest managers to speed the restocking of sites where tree seedlings face competition from grasses for limited moisture, light and nutrients. Retarded growth or, more commonly, death of the seedlings would occur if a selective herbicide was not used to control competing...

Effects of herbaceous weed control on young Douglas-fir moisture stress and growth

Creator:: Preest, David Stanley
Abstract:: Profitable, even-aged forest management depends on the early establishment and rapid growth of each new forest crop. These, in turn, require that the young trees have access to an adequate supply of native resources of moisture, nutrients and light. In Mediterranean-type climates, competition for soil moisture is the most serious...

Internal moisture relations of standing Douglas-fir trees injected with organic arsenicals

Creator:: Holt, Harvey Allen
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) ranging from 9.6 to 14.3 inches diameter breast height were treated with the organic arsenicals, monosodium methanearsonate (MSMA) and cacodylic acid. Treatments were applied at monthly intervals from February, 1967 to October, 1968, to ten to 25 trees each month. Treated trees were sampled in...

Nutrient losses and nitrogen mineralization on forested watersheds in Oregon's Coast Range

Creator:: Miller, James H.
Abstract:: Nutrient losses of the biologically responsive anions, nitrate and bicarbonate together with the major cations, were monitored on 14 small watersheds in Oregon's Coast Range and evaluated in relation to management-induced disturbance. Mixed forests of Douglas-fir and red alder had dominated these high-nitrogen sites prior to treatment. A paired-watershed experimental...

Reactions of protein with phenols and quinones evaluation of amino acid modification and protein digestibility

Creator:: Wehr, Herbert Michael
Abstract:: Plant tissues contain a wide variety of phenolic compounds, frequently in high concentration. Both non-covalent association of intact and oxidized phenols and covalent linkage of oxidized phenols to protein occur. Such interactions can have important biochemical and nutritional significance. A model system approach was used to identify and quantitate amino...

Development of an information processing capacity estimation method for managing a project subjected to disruptions

Creator:: Ro, In Kyu
Abstract:: This dissertation is an attempt at developing a method for the analysis and estimation of the effects of disruptions due to uncertainties. Such uncertainties may result from design changes and engineering drawing delays in large-scale, complex, research and development, or construction projects. In order to provide management with a simple...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...

A green algal symbiont in Clinocardium nuttallii

Creator:: Hartman, Michael Colyn
Abstract:: Clinocardium nuttallii from Yaquina Bay, Oregon, were found to harbor an algal symbiont in the siphon, mantle and occasionally the foot tissues. Approximately 35 percent of the population in the study area was infected to some degree with the alga; however, no cockles under two years of age were infected....

Multi-factor information theory models and their industrial applications

Creator:: Shirland, Larry Elwyn
Abstract:: This dissertation treats information theory and its applications to the general area of decision making. Specifically, three areas are covered; (1) information theory applied to Bayesian analysis, (2) estimation using multi-factor information channel models, and (3) information theory applied to Markov chain analysis. A major portion of this dissertation concerns...
