Models of a four-species annual weed community : growth, competition, and community dynamics

Creator:: Roush, Mary Lynn
Abstract:: Models of weed communities aid in the development of weed management strategies and elucidate the processes and mechanisms that regulate plant populations and communities. A conceptual weed community model was developed to organize key regulatory life-history processes. Specific investigations focused on the processes of plant growth and competition, and relationships...

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...

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...

Wood density patterns of young Costa Rican trees in planted and natural forests

Creator:: Baker, David C.
Abstract:: In plantation forestry, rapid growth rate is favorable for wood production, but may decrease wood density, which is an important indicator of wood quality for both pulp and solid wood products. I looked for (1) differences in radial patterns of wood density between planted and naturally grown Costa Rican tree...

The effects of density and proportion on spring wheat and Lolium multiflorum Lam

Creator:: Concannon, Julie Ann
Abstract:: This thesis consists of four chapters. Literature is reviewed in Chapter 1. Chapter 2 describes an addition series experiment to determine the influence of species density and proportion on vegetative and reproductive yield of spring wheat and Lolium multiflorum. Chapter 3 consists of a growth analysis experiment to determine whether...

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...

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...

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...
