The biology and ecology of Potentilla recta in the Blue Mountains of northeastern Oregon

Creator:: Tuitele-Lewis, Jamison
Abstract:: Two experiments were conducted on the invasive plant species Potentilla recta in northeastern Oregon to investigate both biological and ecological characteristics of the species. Growth analysis was conducted on the plant at three sites over a period of two years (2002 and 2003). Relative growth rate (RGR) was calculated for...

Agroforestry farming in American Samoa : a classification and assessment

Creator:: Tuitele-Lewis, Jeannette D.
Abstract:: Agroforestry is a traditional farming practice in American Samoa that has helped to sustain the livelihood of the native population for centuries. These once self-sufficient islands have become economically dependent on U.S monies and other external resources during the past century. Dependency has caused a shift in the carrying capacity...

Individual and population responses to abiotic stresses in Italian ryegrass (Lolium multiflorum Lam.)

Creator:: Martinez-Ghersa, Maria Alejandra
Abstract:: Plant form is a compromise between resource gathering, reproduction and the tolerance to physical demands of the abiotic and biotic environment. In an agricultural field in addition to the natural factors causing stress, humans also introduce physical and mechanical stresses, and chemical pesticides into the environment. Many of these factors...

Competitive interactions in young, coastal Douglas-fir/red alder mixtures : implications for wood quality

Creator:: Grotta, Amy T.
Abstract:: When Douglas-fir and red alder grow in mixture, interactions between the two species can be competitive, facilitative, or a combination of both over time. A number of factors have recently led to increased interest in managing these two species together for commercial production, and ongoing investigations are yielding important information...

Life-history and physiological trade-offs to reproduction of invasive and noninvasive Rubus

Creator:: McDowell, Susan C.
Abstract:: The goal of this dissertation was to improve our understanding of the physiology and life-history of invasive plants and of the mechanisms underlying life-history trade-offs. I compared invasive and noninvasive species of Rubus (blackberry) that grow together in the Pacific Northwest. Three hypotheses were investigated: (1) Invasive Rubus have higher...

Hydraulic properties of compression wood in branches and reoriented shoots of Douglas-fir (Psuedotsuga menziesii)

Creator:: Spicer, Rachel
Abstract:: Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To...

A stable carbon isotope approach to distinguish climate stress from other imposed stresses in coniferous forests

Creator:: Panek, Jeanne A.
Abstract:: To understand the effect of human-induced stresses on forests, there is a need for a method to separate effects of imposed stress from effects of natural climate stress. I developed an approach to predict forest response to climate stress using as indicators stable carbon isotopes in tree foliage and growth-rings....
