Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...

Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

Creator:: Mangla, Seema
Abstract:: Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

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...

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:: Maxwell, Bruce D.
Abstract:: Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...

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...

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...
