The marine cyanobacterium Lyngbya majuscula has proven to be extraordinarily rich in bioactive secondary metabolites. This dissertation describes the chemistry of L. majuscula collected from Grenada, Fiji and Papua New Guinea, and the biosyntheses of two L. majuscula metabolites, curacin A and barbamide.
The chemical studies with a Grenada collection...
Resident and migratory avifauna in the Willamette Valley, Oregon are heavily influenced by winter conditions and habitat characteristics, especially those of wetlands. As such, it is important to monitor avian communities and environmental factors at wetland sites within the Willamette Valley during winter. Using data from standardized avian point-count surveys,...
Recognisable debris from the Great Tōhoku Earthquake and Tsunami of March 2011 began arriving on the coasts of Oregon and Washington, USA in June 2012. This debris often carried fouling Japanese marine algae, and there was concern that these species might recruit and invade northeast Pacific shores. From June 2012...
From 1925 to 1930, Ernest H. Wiegand, a professor of Horticultural Products at Oregon State Agricultural College, developed an improved brining process for cherries. Brined cherries are used in the production of maraschino and glacé cherries, which already had a sizable market in the United States by the 1920s. This...
Variations in ocean conditions influenced by climate fluctuations may impact fish populations by changing their spatial distribution, physiology, survival, and other ecological features. Somatic growth is a crucial aspect of the biology of fishes and an important contributor to biomass fluctuations. Climate variability also affects somatic growth rates along the...
The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...
This report, required by state law under HB3543, provides a comprehensive assessment of the state of science of climate change as it pertains to Oregon, covering the physical, biological, and social dimensions. The first chapter summarizes the current state of knowledge of physical changes in climate and hydrology, focusing on...
The Pacific Coast Groundfish Fishery harvests a diverse and large grouping of fishes, but it did not become heavily fished until around WWII. This makes the groundfish fishery a comparatively young fishery. Despite its youth, it is one of the largest and most lucrative fisheries in Oregon—with a current harvest...
