Indole-3-carbinol (13C), a metabolite of glucobrassicin, is found in cruciferous vegetables. It is able to act as an inhibitor or promoter of carcinogenesis depending on the species, the carcinogen and when it is given in relation to the carcinogen. This is probably due to the fact that it reacts in...
This thesis is a study of the effects of social media and the influence it has over people and their wellbeing. The study within the thesis manipulates the social media habits of Oregon State students, and looks at the changes in their wellbeing. Throughout the background research the evidence supports...
Fire regimes across the western United States have been altered due to past land management and changing land use. Mitigating increased risks of wildfire occurrence in landscapes such as central Oregon requires landscape level management from both governmental and private organizations. Non-industrial private forest (NIPF) owners manage a relatively small...
Two methods of estimating surface velocity vectors from advanced very high resolution radiometer (AVHRR) data were applied to the same set of images and the results were compared with in situ and altimeter measurements. The first method used and automated feature –tracking algorithm and the second method used an inversion...
Understanding the factors that control predation in pelagic communities can inform predictions of community structure in marine ecosystems. Ubiquitous and selective predators such as cnidarian hydromedusae rely on their nematocysts to capture and retain prey but it is not clear how the density and spatial distribution of these cells relate...
Interannual variation in precipitation totals is a critical factor governing the year-to-year availability of water resources, yet the connection between interannual precipitation variability and underlying event- and season-scale precipitation variability remains unclear. In this study, tropical and midlatitude precipitation characteristics derived from extensive station records and high-frequency satellite observations were...
Tides in the Delaware Bay (USA) have been modeled from 7000 years before present (7 ka) to the present day and for selected future sea-level rise scenarios (100 years, 300 years). Historic bathymetries were constructed through use of glacial isostatic adjustment models and a very high spatial resolution (< 100...
Despite the availability of selenium (Se)-enriched trace mineral supplements, we have observed low Se status in cattle and sheep offered traditional inorganic Se supplements. Reasons for this may include inadequate intake or low bioavailability of inorganic Se sources. The objective of this study was to determine whether rumen microorganisms (RMO)...
Recent mandates in the United States require federal agencies to incorporate climate change science into land management planning efforts. These mandates target possible adaptation and mitigation strategies. However, the degree to which climate change is actively being considered in agency planning and management decisions is largely unknown. We explored the...
Limited approaches exist for studying population connectivity in widely dispersing marine benthic invertebrates. Genetic techniques can provide important insights toward identifying recruitment trajectories. Here, 10 microsatellite loci were used to examine connectivity among Oregon Dungeness crabs (Cancer magister, Dana, 1852) in the California Current System (CCS) (n = 801) as...
