The reactions of aldehydes with proteins are of nutritional and
physiological significance. The nutritive value of food materials can
be impaired by a reaction necessitating additional dietary protein,
and enzymes have been shown in vitro to be inhibited by reactions
with aldehydes.
Aldehydes present may arise from the autoxidation of...
Tree growth and soil nutrient responses to prescribed underburning were determined for a period of up to 12 years at four sites in northcentral and central Oregon ponderosa pine stands (Pinus ponderosa Dougl. ex Laws).
Differences reported are significant at a = 0.10. During the first 4-growing-season-measurement period after
underburning,...
The effects of prescribed underburning on soil total C pools, total and inorganic N pools, and in situ net N mineralization were examined during a 1-year study in ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) sites that had been experimentally burned 4 months, 5 years, or 12...
The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...
Malonaldehyde, a three carbon dialdehyde, is one of the numerous
carbonyl compounds associated with oxidative deterioration of
food lipids. It is assumed to be formed as a product of lipid autoxidation
occurring according to the generally accepted free radical
mechanism. This compound is of great interest because of its potential...
