Individual and combined effects of cyanide, pentachlorophenol and zinc on juvenile chinook salmon and invertebrates in model stream communities

Creator:: Negilski, David Stanley
Abstract:: The effects of sublethal concentrations of cyanide, pentachlorophenol and zinc individually and in combination on the growth and production of juvenile chinook salmon, Oncorhynchus tshawytscha (Walbaum), and aquatic invertebrates in model stream communities were studied in three experiments during 1971 and 1972 at the Oak Creek Fisheries Research Laboratory, Oregon...

Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

Creator:: Marnell, Patrick Stanley
Abstract:: Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues...

Seasonal changes in distribution and abundance of salmonids and habitat availability in a coastal Oregon basin

Creator:: Sleeper, Jack David
Abstract:: Visual estimation techniques were used to quantify habitat characteristics, habitat type (pool, riffle) use and longitudinal distribution of steelhead (Oncorhynchus mykiss), cutthroat trout (0. clarki), and coho salmon (0. kisutch) in spring, summer and fall in 8.8 km of Cummins Creek, a basin in the central coast of Oregon. Fish...

Spatial, diel and seasonal variations in dissolved oxygen and temperature within a stratified lake

Creator:: Smith, Stanley Allan
Abstract:: Spatial, diel and seasonal variations in dissolved oxygen and temperature were measured in Triangle Lake, Oregon. Spatial dissolved oxygen and temperature variations measured in the stratified lake are presented to illustrate the horizontal uniformity of the lake and to demonstrate the applicability of the one dimensional assumption for sampling and...

Zinc-phosphorus relationships in five plant species

Creator:: Henning, Stanley John
Abstract:: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses...

Aluminum toxicity in the primary meristem of wheat roots

Creator:: Henning, Stanley John
Abstract:: The progression and consequences of aluminum toxicity were studied microscopically in the root tips of four wheat varieties representing different classes of Al tolerance. The root tips studied were collected from seedlings grown in nutrient solution cultures containing either sublethal or lethal Al treatments which were unique for each variety....

Diversity and community structure of aquatic insects in isolated montane desert streams

Creator:: Bogan, Michael T.
Abstract:: Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...

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...

Summer soil moisture dynamics in a young Douglas-fir plantation as influenced by three herbaceous weed communities

Creator:: Preest, David Stanley
Abstract:: The use of chemicals such as the triazines (especially atrazine) and mixtures of the triazines and 2,4-D or 2,4,5-T has become almost standard practice in some parts of the world for selectively controlling grasses and other herbaceous weeds to conserve moisture for and/or prevent the smothering of newly-planted conifers. In...

Evaluation of the influence of multi-level reading materials on the achievement of fifth grade elementary science pupils when placed at reading level by an informal reading inventory

Creator:: Daugs, Donald Roger
Abstract:: The purpose of this study was to statistically evaluate the influence of student placement at reading level by means of an informal reading inventory in one kind of elementary science materials. The materials were written at five levels of reading difficulty to better meet the reading ability spread found in...
