A theory of the origin and distribution of fishes in the Harney Basin is presented. Blitzen River, the hydrographically and ecologically isolated creeks, and the upland tributaries of Silvies River all contain populations derived from the basin's Pleistocene connection with Malheur River of the Snake system. Colonization of many streams...
Lahontan cutthroat trout (LCT) (Oncorhynchus clarki henshawi) are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. The objectives of this study were to determine how landscape level topographic features influence LCT distribution patterns....
Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...
Based on recent findings, our hypothesis is that the inhibition of the Receptor tyrosine kinase-like orphan receptor 2 (ROR2) enzyme can lead to tumor suppression.
ROR2 are trans-membrane proteins that are part of the receptor tyrosine kinase (RTK) family. ROR2 is generally not expressed in most normal adult tissues and...
This thesis presents the idea for FORIN (Forest Roads Inventory), a computerized forest roads inventory system. FORIN is a tool to more efficiently inventory and manage information of forest roads. FORIN is intended for use by field personnel, who will use pen-based computers to improve productivity, accuracy of inventories, to...

A THESIS
In the first experiment the minimum dietary toxic levels of vitamin A were determined in pregnant rabbits over three parities. The treatments consisted of basal diet plus 10,000, 30,000, 60,000, and 90,000 IU/Kg added vitamin A. The basal diet was formulated to be free of vitamin A and beta-carotene; rice...
I examined the relative roles of biotic and abiotic factors in structuring redband trout
Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the
relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...
Native to the Pacific Northwest, Ceratomyxashastais a myxosporeanparasite that infects wild and cultivated salmon and has a significance impact on its population in the Klamath River basin. The study suggests that the transmission of mixed genotypes of the parasite are common in Chinook salmon but the age of the fish...

More needs to be done by the private sector to optimize the drug discovery and development pipeline. In addition, significant efforts should also be focused on the understanding of mechanism of diseases, on the characterization of unexplored biochemical pathways and on the validation of new protein targets. Chemical genomics, which...
Shifting the Scholarly Conversation: A Rhetorical Reading of Peter Elbow's Work explores Peter Elbow's contributions to the field of writing and rhetoric. Over the course of his long career, Elbow’s scholarly and pedagogical work has been much praised and much criticized. Elbow's work has influenced generations of teachers and writers,...
