Two objectives of this research were to identify fungi which are
mycorrhizal with western hemlock and to examine the ecology of hemlock
mycorrhizal fungi indigenous to outplanting sites. Another objective
was to evaluate the effectiveness of mycorrhizal inoculation in
improving the performance of outplanted hemlock seedlings.
A list of over...
Despite ongoing initiatives and research efforts, the persistent underrepresentation of marginalized groups in Science, Technology, Engineering, and Math (STEM) disciplines in the U.S. has seen little improvement. This study posits that a fundamental change in teacher preparation can lead to more inclusive STEM learning environments. It centers on the development...
A fiber optic fluorometer utilizing a double-fiber optic probe
was constructed. The absolute fluorescence signal and effective
collection efficiency are approximately one fifth those of typical
cuvette fluorometers and agree with those predicted by theory. A
quinine sulfate calibration curve shows linearity from a detection
limit of 10 pg/mL to...
Wildfire impacts have intensified in many ecosystems across the western United States due to the combined impact of fire exclusion, climate change, and land management practices. However, on many of these landscapes, fire is a fundamental ecological process that has shaped vegetation structural and compositional diversity, ecosystem function, landscape pattern,...
Internship and field experience programs have been used to
prepare educators for roles in public school teaching and administration;
junior college and university teaching, and adult education.
Based on a survey of the literature it is apparent that little attention
has been given to the role that these internship and...
Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...
Supervised exercise interventions can elicit numerous positive health outcomes in
breast cancer survivors. However, to maintain these benefits, exercise needs to
continue long after the supervised program. This may be difficult, as in this
transitional period (i.e., time period immediately following a supervised exercise
program), breast cancer survivors are in...
Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...
