Samples of benthic algae were collected from the Metolius River
of central Oregon at two-week intervals between April 15, 1967 and
March 9, 1968. Species of filamentous algae and diatoms present
were recorded for every sampling station on each sampling date.
Permanent mounts of diatom frustules were prepared.

In this thesis, I examine the experiences of breastfeeding mothers who chose to give birth with Certified Professional Midwives at a free-standing birth center, and the factors that influence their known high rates of breastfeeding initiation and duration. Using grounded theory and data collected from participant observation, semi-structured interviews, and...
Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...
Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...
