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....

Factors affecting the regrowth of Himalya (sic) blackberry (Rubus armeniacus)

Creator:: Jones, Daniel Karl
Abstract:: Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This...

Water relations, survival and growth of Douglas-fir seedlings at a pinegrass dominated site in the interior Douglas-fir zone of south-central British Columbia

Creator:: Nicholson, Alison Campbell
Abstract:: A field study was conducted to determine the impact of microclimate and vegetation on survival and growth of planted Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) at a pinegrass (Calamagrostis rubescens Bucki.) dominated clearcut in the Interior Douglas-fir Zone of south-central British Columbia. The study focussed on (1) the water balance of...

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...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:: Stocking, Peter
Abstract:: Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

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 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 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...
