Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Stress response as a basis for disease susceptibility in Ponderosa Pine

Creator:: Koonce, Andrea
Abstract:: Trees stressed by artificial and natural means were sampled for response in growth and vigor, carbohydrate content, resin pressure characteristics, and water relations. Tree response was found to reflect both the severity and type of stress imposed. Crown color and appearance were reliable indicators of prolonged stress and advanced decline...

The influence of vegetable fibers on mineral balance in the rat

Creator:: Tinsley, Joel Ray
Abstract:: Dietary fiber has been suggested as interfering with mineral utilization. The influence of broccoli florets and wastes, cauliflower heads and wastes, wheat bran and Metamucil on mineral uptake by the rat was determined using balance studies. All results were compared to control animals fed diets containing 10% hydrolyzed cellulose. Utilization...

The isolation and structure of leptosphaerin : a metabolite of the marine ascomycete, Leptosphaeria oraemaris (Linder) and A synthesis of the marine toxin, 9-isocyanopupukeanane

Creator:: Schiehser, Guy Alan
Abstract:: The ethyl acetate extract of the culture filtrate of the marine Ascomycete, Leptosphaeria oraemaris (Linder) yielded a novel metabolite designated by the common name leptosphaerin. An x-ray crystallographic structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)- 3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine 47 and D-mannitol 44. Oxidation of 47 followed...

Studies on the cytoplasmic malate dehydrogenase from a larval halophilic crustacean, Artemia salina

Creator:: Hand, Steven Craig
Abstract:: The cytoplasmic isozyme of malate dehydrogenase (s-MDH) has been isolated from brine shrimp nauplii to a state of high purity with a protocol involving ammonium sulfate fractionation and chromatography on DEAE-cellulose, followed by sequential passes over cellulose phosphate columns at pH 5.8 then 5.0. The purified enzyme is free of...

Distribution and variation of Armillariella mellea clones in relation to vegetative cover and severity of root rot in Ponderosa pine

Creator:: Cooley, Sally Joan
Abstract:: Root rot due to Armillariella mellea (Vahl. ex Fr.) Karst. is unusually severe in ponderosa pine near Glenwood, Washington. Isolate relations, clonal variability, vegetation patterns, and climate were examined in relation to severity of disease in this area. Ninety-one isolates from 70 infection centers were examined. Pairings of neighboring isolates...
