Aerial application of fosamine ammonium or glyphosate at moderate rates was not adequate for controlling understory brush before final harvesting of mature Douglas-fir (Pseudotsuga menziesii) stands or for reducing vigor of post-harvest sprouting. Symptoms of herbicide injury were those associated with low application rates, suggesting that the canopy intercepted too...
During summer and fall 2007, I traveled across Europe and studied in Spain. My experiences abroad shaped my reading of certain literary texts as I gained insight into the cultures and settings in which they were produced. In my thesis, I recount some of these experiences and show how my...
Increasing numbers of children are entering kindergarten without the behavioral skills needed to cope with the demands of the classroom environment. Moreover, a number of studies have documented that young children's behavioral regulation (including attention, working memory, and inhibitory control skills) plays an important role in later academic achievement (McClelland,...
Lingcod are an overexploited fish species in the Pacific Northwest and although there has been extensive study of the habitat requirements of adults, particularly during spawning, relatively little is known regarding the habitat requirements of post-settlement juveniles. Many juvenile fish use structural components of habitat to alleviate the risk of...
Juvenile English sole, Parophrys vetulus utilize Yaquina Bay, Oregon, as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of the-year first appeared in Yaquina Bay in February,...
Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...
Genetic diversity within populations is an important component of adaptive evolution, and recent research has demonstrated that genetic variation within plant populations can have important ecological effects. In this study, we investigate quantitative-genetic variation in several traits within a quaking aspen (Populus tremuloides Michx.) population. A common garden experiment was...
