Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...
Horticultural and nursery crops are the leading agricultural commodity in Oregon. Among currently grown nursery plants, Verbena x hybrida is a staple ornamental. It is grown and shipped worldwide, thus requiring a high level of certainty concerning the plants’ health and potential viability. V. x hybrida cultivars have been infected...
Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...
In June of 1994, the Oregon Agricultural Statistics Service (OASS) conducted a commodity survey that included an estimate of the number of equines (horses, ponies, mules, donkeys, miniatures, and zebras) in Oregon.
Twentieth century commercial whaling drastically reduced the abundance of great whale populations in the Southern Ocean. Exploitation began on the south Atlantic island of South Georgia, where catch records account for over 175,000 whales killed. Modern whaling within the Southern Ocean depleted populations rapidly, and by 1966, hunting blue whales...
Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...
This thesis employs a narrative analysis of more than twenty-five films that are
centrally concerned with immigrants and the immigrant experience. In Part One,
drawing from the work of Yosefa Loshitzky, I will focus on films that feature an
immigrant lead character. In Part Two, I will explore movies that...
The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...
The Antarctic krill (Euphausia superba Dana 1852) is widely distributed throughout the southern ocean, where it provides a key link between primary producers and upper trophic levels and supports a major commercial fishery. Despite its ecological and commercial importance, genetic population structure of the Antarctic kill remains poorly described. In...
