A biological and systematic study of the armored boreid, Caurinus dectes, with comparative notes on related mecoptera

Creator:: Russell, Loren Kenneth
Abstract:: Caurinus dectes Russell is a minute, brachypterous scorpionfly which was discovered at Marys Peak, Benton County, Oregon, in 1976, and subsequently described as the only representative of the subfamily Caurininae within the Boreidae (snow scorpionflies). Caurinus dectes is now known to range from the Olympic Peninsula and Northern Cascades in...

A comparison of taste responses in pygmy goats, normal goats, sheep and cattle

Creator:: Goatcher, William Donald
Abstract:: This study involved the use of the two-choice preference test to determine the taste responses of eight, each, of pygmy goats, normal goats, sheep and cattle to ascending concentrations of sucrose (Suc), sodium chloride (NaC1), acetic acid (HAc) and quinine hydrochloride (QHCI). In addition, sheep and cattle were tested at...

A new model for the formation of Crater Lake Caldera, Oregon

Creator:: Lidstrom, John Walter
Abstract:: During the Pleistocene, an andesitic volcano named Mount Mazama grew to a probable elevation of 3000 meters in south- central Oregon. Near the end of the Pleistocene, three diverse magma types appeared in the eruptive products associated with Mount Mazama: l)High-alumina basaltic andesite magma associated with an early plateau and...

Alfalfa cutting management in the Columbia Basin

Creator:: Suttner, Donald Lee
Abstract:: Field studies to determine appropriate cutting management regimes consistent with yield, quality, and persistence of stand were conducted on several alfalfa varieties in the Columbia Basin region of Oregon. Two groups of treatments, including consecutive cuts at the same stage of maturity and cuts made at varying maturities, were imposed...

Aluminum toxicity in wheat (Triticum aestivum Vill., host)

Creator:: Kerridge, Peter Campbell
Abstract:: Wheat varieties of differential tolerance to Al were used in a series of nutrient solution experiments to study the inhibitory effects of Al on growth and nutrient uptake. The pH and the Al and P concentrations were rigorously maintained to prevent the confounding effects of Al and P precipitation and...

An econometric investigation of demand interrelationships among tree nuts and peanuts

Creator:: Dhaliwal, Hardev Singh
Abstract:: Edible tree nut and peanut industries are important agricultural industries in the United States. Major tree nuts produced domestically are almonds, filberts, pecans,and walnuts. The United States imports and exports some quantities of these tree nuts and peanuts, but at the same time the U.S. imports cashew, brazil, pignolia, and...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...

Characterization of the transition to the progamic phase in Zea mays pollen

Creator:: Smyth, Johanna C.
Abstract:: The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....

Clay mineralogy and related chemical properties of soils formed on Mazama pumice

Creator:: Chichester, Frederick Wesley
Abstract:: A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central Oregon. The <2 μ size fraction from each sample was characterized with respect to the relative significance of amorphous and crystalline components, and the individual minerals of the latter group were...
