Influence of ruminant digestive processes on germination of ingested seeds

Creator:: Lowry, Amaya A.
Abstract:: Managing cattle to disseminate seeds of desirable plants, or alternatively, to restrict weed seed contamination on rangelands is of interest to managers. Four experiments were conducted to determine effects of ruminant digestion on germination of ingested seeds. A number of plant species representing a variety of seed size and seed...

The effects of defoliation on yellow starthistle (Centaurea solstitialis L.) reproductive capacity

Creator:: Schumacher, Stacy
Abstract:: Yellow starthistle (Centaurea solstitialis L.) is an introduced Asteraceae that has become established on 10 million acres in the Pacific Northwest and California. This weed functions as an annual or short-lived perennial and depends on seeds for reproduction. Strategies of control that reduce plant fitness or lower seed production or...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Controlling Important Pathogens in Zebrafish (Danio rerio) : Assessing Cryopreservation Survival of Bacteria and Parasites and Clinical Sensitivity of Mycobacterial qPCR Assays

Creator:: Norris, Lauren J.
Abstract:: Zebrafish (Danio rerio) are one of the most commonly used animal models in biomedical research. Zebrafish resource facilities, like the Zebrafish International Resource Center (ZIRC) in Eugene, Oregon, are the main providers and keepers of numerous zebrafish wild-type, mutant, and transgenic lines. Although ZIRC maintains live zebrafish at various life...

Intestinal hyperplasia and neoplasms in zebrafish (Danio rerio)

Creator:: Paquette, Colleen Elizabeth
Abstract:: Zebrafish (Danio rerio) have become an increasingly important model organism for cancer research. There are several cancer models in which neoplasms are induced chemically or genetically. However, spontaneous (unknown etiology) neoplasms are rather common in zebrafish, particularly in older fish. For over a decade, spontaneous intestinal neoplasia and preneoplastic intestinal...

Restoring the Columbia River Estuary : Chinook Salmon Recovery and Invasive Species Management

Creator:: Klopfenstein, Rachael
Abstract:: As highlighted in this study, shallow-water habitats and the prey they provide are important for juvenile salmon in the Columbia River estuary, but the spread of invasive species and large-scale changes to the estuary influence how these habitats are utilized. Reed canarygrass (Phalaris arundinacea) (“PHAR” hereafter) is a highly invasive...

Influence of spacing and crown recession on wood quality of intensively-managed young-growth Douglas-fir

Creator:: Robbins, James M.
Abstract:: Intensive management of young-growth Douglas-fir plantations has emphasized volume growth over wood quality. A better understanding of the variables that affect wood quality is needed so that wood quality and stand yield can be systematically combined into a silviculture program. This experiment utilized two separate experiments to establish the relationship...

A matrix game approach to linear programming

Creator:: Park, Tongkyu
Abstract:: It is the hope and expectation of many specialists in the area of linear programming that a major improvement in solution techniques for handling large-scale models with thousands of constraints will be developed in the near future. Although the present state of the art for solving linear programs is still...

Ecology and applications of cutaneous mechanisms of resistance to amphibian chytridiomycosis

Creator:: Nebergall, Emily E.
Abstract:: Amphibian biodiversity is in rapid global decline, due in part to the fungal disease chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd). Susceptibility to Bd and chytridiomycosis varies between species and populations. Skin peptides and symbiotic skin bacteria appear to be important mechanisms of Bd resistance. However, not much is known about...

Describing the thermal regimes of two northeastern Oregon streams

Creator:: Raven, Sonja E.
Abstract:: Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....
