The data gathered for the study of the health status of freshmen
at Oregon State University were derived by an analysis of health history
records. These were obtained from the Oregon State University
Health Service. The years sampled were 1930, 1940, 1950 and 1960;
300 freshman male and 300 freshman...
The purpose of this thesis is to present the results of a study
of the impacts of the Conservation Reserve Program, Title XII of the
Food Security Act of 1985, on the economies of small communities
located in Gilliam, Morrow and Umatilla Counties in Oregon. These
counties are representative of...
From a landscape ecology perspective, meadows are often seen as landscapes in
transition. Succession and change in meadows may be investigated by considering the
physical and anthropogenic factors that influence the landscape through time. What is
often unknown is how changes occur and how physical and anthropogenic factors
contribute to...
Historically, researchers have used surveys, focus groups, and anecdotal evidence to evaluate consumer response to environmentally certified, ecolabeled forest products. These methods generally measure consumer attitudes toward certified forest products. Since the strength of the correlation between attitudes
and behavior has long been questioned, consumer response to certified forest products...
Seven streams, one of them permanent, were studied in
western Oregon, USA. The research was designed to assess
the value of summer-dry headwaters for conservation
oriented landscape management. Streams were categorized
primarily according to exposure (forest versus meadow
sites) and secondarily according to flow duration
(ephemeral = short-flow versus temporary...
The activity of deoxyribose-phosphate aldolase was determined
in chick embryo brains, hearts and livers during the course of development.
Assays were made in the direction of synthesis of deoxyribose-5-phosphate. Low levels of activity in the brain and heart
remained constant throughout the course of development. Activity in
the liver expressed...
Efforts to manage stocks of salmonids in Pacific Northwest stream systems are complicated by the occurrence of several runs of a species thought to represent races rearing sympatrically as juveniles. In order to collect the population statistics needed to properly manage these stocks, managers need a method of identifying juvenile...
