Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

Modeling Transport, Retention, and Growth of Early Life Stages of Small Pelagic Fishes in the Southern Humboldt System

Creator:: Gomez, Fabian A.
Abstract:: Small pelagic fishes (SPF), such as anchovies and sardines, are ecologically important due to their large abundance and intermediate trophic position that links plankton production to upper trophic levels. They are also economically important, supporting large fisheries that contribute to one fourth of the world fish landings. Reproductive success in...

Modeled Larval Connectivity Patterns in two Coral Reef Regions : the Western Caribbean and the Kenyan-Tanzanian Shelf

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: Tropical coral reef ecosystems are very important from both the ecological and economical points of view. However, they are also particularly fragile, and have been declining in recent years in most regions of the world, since they are highly susceptible to anthropogenic stressors operating at global scales (e.g., global warming...

Bioenergetics and behavior of the krill Euphausia pacifica in the California Current System off the Oregon coast

Creator:: Lindsey, Brie J.
Abstract:: Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is essential to understand both the behavior and bioenergetics of this...

Petrogenesis of compositionally distinct silicic volcanoes in the Three Sisters region of the Oregon Cascade Range : the effects of crustal extension on the development of continental arc silicic magmatism

Creator:: Hill, Brittain Eames
Abstract:: The Three Sisters region of the Oregon High Cascades has developed three compositionally and petrogenetically distinct silicic (i.e., SiO₂ ≥ 58%) magma systems within the last 600 k.y. These silicic systems evolved from the same High Cascade mafic magma system and developed in the same 20x30 km area of the...

Predicted economic effects of environmental quality control policies on linear firm models and an application to an irrigated farm model

Creator:: Clark, Richard T.
Abstract:: Linear economic models were utilized to predict effects of various environmental control policies on individual firms. Four different linear models were specified and in some instances relatively minor changes in specification were made which resulted in additional sub-models. Models varied as to numbers and types of fixed factors, variable cost...

Hydric Soils in Eastern Oregon Temporary Pools

Creator:: Clausnitzer, David
Abstract:: Two types of temporary poois, known as playas, occur in semiarid southeast Oregon. Vegetated upland playas are found in the High Lava Plain province; barren alkaline-saline playas are found in the Basin and Range province. Both types become ponded in most years, but they often lack redoximorphic features indicative of...

Studies on the occurrence, physiology, and ecology of bioluminescence in dinoflagellates

Creator:: Esaias, Wayne E.
Abstract:: To provide further information on the occurrence and geographical variations of bioluminescent capabilities of marine dinoflagellates, forty species, representing twelve genera, of dinoflagellates from Yaquina Bay, Oregon, were examined for bioluminescence as single cell isolates. Seventeen species from the genera Ceratium (1 sp.), Gonyaulax (3 sp.), and Peridinium (13 sp.)...
