Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

Creator:: Ackerman, Luke K.
Abstract:: Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...

Spatial and temporal changes of sage grouse habitat in the sagebrush biome

Creator:: Miller, Richard F., Eddleman, Lee, and Oregon State University. Agricultural Experiment Station
Abstract:: This paper was written as a book chapter on the ecology and biology of sage grouse. Because the book was never fully developed, we chose to publish the information with the OSU Agricultural Experiment Station.
Resource Type:: Technical Report
Full Text:: over 29 million ha in the Intermountain Region (West 1984, 1999) and occur on a wide variety of soils

Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:: Schrlau, Jill E.
Abstract:: The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Post-fire vegetation response to snow in the western United States

Creator:: Blauvelt, Katie
Abstract:: The western United States is experiencing significant changes in wildfire and snow regimes as a result of warming temperatures. An amplification of wildfire activity and reduction in snow water equivalent, snow covered area, and earlier spring snowmelt are documented trends that are projected to continue into the future. With an...

The effects of atrazine on growth of flax (Linum usitatissimum L.) plants and on yield, chemical composition and germination of flax seeds

Creator:: Locatelli, Eduardo Atilio
Abstract:: Reports of previous research indicated a stimulatory effect of triazine herbicides on growth, yield and protein content of plants and seeds of various species. Studies were conducted in the greenhouse, laboratory and field to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino- s-triazine) on growth, yield, seed composition, and seed germination...

Individual and demographic responses of the gray-tailed Vole (Microtus canicaudus) to an endocrine disruptor

Creator:: Caslin, Tracie M.
Abstract:: In an experimental field study, populations of gray-tailed voles (Microtus canicaudus) were exposed to a commercial formulation of vinclozolin, a fungicide effective for disease control on ornamental plants, turf grasses, and fruits and vegetables. Vinclozolin has been shown in laboratory experiments to behave as an androgen antagonist, impairing the reproductive...
Resource Type:: Masters Thesis
Full Text:: with one application of Curalan® fungicide, Vinclozolin had only a slight effect on the reproductive

Developmental axial skeletal deformities : baseline study with a zebrafish model

Creator:: Harden, Jon M.
Abstract:: The aim of this study was to assess sensitivity of early life stage zebrafish to cadmium (Cd). Embryos and larva were exposed to Cd before the formation of skeletal elements. Exposure times were selected to determine whether Cd perturbed developmental processes that lead to skeletal deformities, and to characterize the...
Resource Type:: Masters Thesis
Full Text:: . There was no effect of Cd on incidence of any type of skeletal deformity at 4Odpf(P>O.05 and p>O.O5

Reduction of salmonid predators by chemical treatment

Creator:: Reeher, James A., Hewkin, James A., West, Duane C., and Oregon. State Game Commission. Fishery Division
Abstract:: The upper drainage of the John Day River system produces summer steelhead and spring chinook salmon. The fish are generally confined to the main stem and its tributaries above Prairie City. The spawning and rearing areas are comparatively free of undesirable fish species, but salmonid smolts migrating downstream must travel...
