The life history of the fungus involved and the control for cherry
leaf spot was studied ever a two-year period. It was found that the
disease in Oregon is caused by the same fungus described in New York by
Higgins in 1914 as Coccomyces hiemalis and which was more recently...
For over 100 years, National Parks have existed to preserve America’s natural and cultural heritage for current and future generations. As environmental pressures on wildlife and habitats have increased in recent decades, National Park lands have become important protected areas for many threatened and endangered species. Conservation and management of...
Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....
The research conducted here originated with the question of what caused the massive build-up of nuclear arsenals, which included ever larger and more powerful bombs and delivery systems from them, in the United States and the Soviet Union, even though the consensus beforehand was that nuclear energy should be prohibited...
This project examines the production histories of two films that Alfred Hitchcock directed, his Hollywood debut Rebecca (1940) and the memorable Psycho (1960). The first chapter explores how Hitchcock succeeded and failed at influencing the picture as he, despite directing the movie, had to follow the vision that his producer,...
Microplastics (<5mm diameter) are present in a considerable number of marine and aquatic species. Understanding which species, the global spatial distribution, and what quantities of microplastics are present is extremely important for understanding the potential impacts they could have on recreationally important organisms and for the assessment of risk. We...
Shorebirds display great variation in mating systems and breed in dynamic environments that are increasingly subject to human threats worldwide. In order to adequately assess productivity and demography of shorebird populations, it is important to understand factors that influence patterns of parental care and reproductive success. The Black Oystercatcher (Haematopus...
