The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...
Anthropogenic climate change is threatening biodiversity as I currently understand it. There is now a large body of work highlighting species responses, globally, to this threat. Importantly, responses at the species level emerge from responses at lower levels of biological organization (individuals and populations) across a species’ geographic range. For...
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
Contemporary parenting strategies tend to involve
parent-child interactions in which the parent neither
repressively dominates the child nor follows a permissive
laissez-faire course but respects the child's dignity as a
person. This paper integrates several current theories of
parenting and parent education into the construct of
"respectful parenting," which is...
Verticillium dahliae Kleb. incites a vascular wilt disease of
mints. Susceptible Mentha piperita L. , resistant M. crispa L.,
and intermediate hybrid 148 were used to study 1) the site of differential
resistance and 2) the role of polygalacturonase (PG) in the
disease syndrome.
Many more V. dahliae propagules were...
Soils and other resource programs in both public land management agencies and private industry are continually being adapted to the challenges of evolving knowledge and experience in the field of forestry. This dissertation explores new ways of thinking about and using soils information in forest planning and management, with a...
Purpose: The Purpose of this research was to design, implement and evaluate a patient centered asthma intervention pilot program directed by physicians and administered by community pharmacists to a group of Managed Care contracted Oregon Health Plan asthmatics. The evaluation was to determine if the proposed intervention could improve the...
The United States has had a long history of promoting agricultural exports, and the return to conditions of extreme surplus in many agricultural markets in recent years has revived interest in this topic. Some products received imperial bounties during our colonial era, but the systematic collection of trade statistics for...
The purposes of the research presented in this thesis were
to: (l) assess the nutritional status of vegetarian and nonvegetarian
Seventh-day Adventists (SDA), non-SDA non-vegetarians,
and non-vegetarian hormone dependent cancer subjects; (2) determine
the relationship of various blood and urinary biochemical
parameters to dietary intake; (3) determine hormonal status in...
