Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

Creator:: Asquith, Adam
Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...

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...

The influence of selected environmental factors on diuron toxicity to winter wheat

Creator:: Homesley, Wylie Buress
Abstract:: Previous work has shown that diuron (3-(3, 4- dichlorophenyl)-1, 1-dimethylurea) is less toxic to fall-planted wheat than to wheat planted in the spring. Diuron has been a significant factor in increasing yields of winter wheat grown in Oregon's Willamette Valley. The influence of several selected environmental factors on diuron toxicity...

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...

AppleMgr, a prototype decision aid for apple pest management

Creator:: Haley, Sue
Abstract:: Computer decision aids can help integrate and apply diverse sources of information and expertise to problems of integrated pest management (IPM) in agriculture and forestry. AppleMgr combines a rule-based expert system with databases and spreadsheets in a prototype decision aid intended to be expanded and modified for use by extension...

A lysozyme-like protein in the salivary glands of adult Aedes aegypti : functional and biochemical characteristics

Creator:: Pimentel, Gliceria Estandian, 1958-
Abstract:: This study investigated some functional and biochemical characteristics of a bacteriolytic protein in the salivary glands of adult Aedes aecupti. A method for the isolation of this protein from other mosquito salivary gland components is also described. Based on some of its biochemical properties, this bacteriolytic protein can be classified...

Modeling purple nutsedge (Cyperus rotundus L.) growth : preliminary evaluation of light intensity, soil moisture and herbicide effects

Creator:: Amerasinghe, A. A. L.
Abstract:: Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the most troublesome perennial weeds of agricultural lands in tropical and some temperate regions. This research sought to determine the effects of timing of herbicides, shading, and soil moisture on plant population growth and tuber production of purple nutsedge...

Competitive interactions between Douglas-fir or ponderosa pine and whiteleaf manzanita

Creator:: White, Diane E.
Abstract:: Juvenile Douglas-fir, ponderosa pine, and whiteleaf manzanita growth in southwest Oregon varied with density of co-developing manzanita and presence of herbaceous cover. Plant xylem pressure potential and stomatal conductance of each species was responsive to competition-induced depletion of soil water. Rates varied among species. The best correlations with growth usually...

Nutrient losses and nitrogen mineralization on forested watersheds in Oregon's Coast Range

Creator:: Miller, James H.
Abstract:: Nutrient losses of the biologically responsive anions, nitrate and bicarbonate together with the major cations, were monitored on 14 small watersheds in Oregon's Coast Range and evaluated in relation to management-induced disturbance. Mixed forests of Douglas-fir and red alder had dominated these high-nitrogen sites prior to treatment. A paired-watershed experimental...
