Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...
The variation in fatty acid composition between the "bound" and
"free" lipid in stored anchovy meal was determined using gas-liquid
chromatographic analysis. A model system of fresh anchovy oil on
powdered lactalbumin was also studied to determine the changes in
extractability and fatty acid composition which occur during oxidation.
All...
The morphology of the dorsal neck organ of the brine shrimp
Artemia salina nauplius was investigated to determine its role(s)
during larval development.
Light and scanning electron microscopic studies show that the
neck organ is present in the pre-nauplius larval forms as early as
12 hours after hydration of the...
Rainbow trout were fed semi-purified diets containing cyclopropenoid
fatty acids, and the biological effects of these acids were
investigated. These fatty acids occur naturally in cottonseed oil and
have been implicated in a large number of physiological disorders.
Included in this study was an investigation of the pattern of deposition...
Effects of habitat and season on guild structure of avian
communities were examined for islands in the estuary zone of the
Columbia River, Oregon. Bird species were classified into guilds
according to their major food item, typical foraging substrate, and
foraging behavior. Variation in community structure indices (number of
guilds,...
In the 1980s, resource managers were increasingly concerned about effects of timber harvest on ungulates in National Forests. Land and resource management plans incorporated restrictions on timber harvest to maintain cover for Rocky Mountain elk
(CeNus e/aphus ne/soni V. Bailey) and mule deer (Odocoileus hemionus hemionus RafinesqueJ, and habitat models...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
This paper describes the design and implementation of
COLAN V, a High Performance Local Area Network for
Communications and Control utilizing a Communications Coprocessor.
The main objective of this thesis is to improve upon
the performance of previous COLANs in speed, switching
techniques and error detection techniques. This was
possible...
