The colonization of several species of plants by vesicularar-buscular
mycorrhizae (VAM) was studied to determine how host, soil,
or symbiont factors interacted to enhance growth of the host plant.
Seedlings of two species of the Cuppressaceae and two of the
Taxodiaceae formed VAM; colonization significantly improved growth.

This book is an environmental primer for the people of the Willamette Valley. It sets forth basic principles showing how men's actions cause future consequences in the environment.
Between 1907 and 1941, Portland architect John V. Bennes designed more than thirty five new buildings for Oregon State University and designed several other building additions and renovations. This presentation explores Bennes' OSU work as well as his archtectural designs in Portland, Baker City and other Oregon communities.
Between 1906-41, John Bennes was one of Portland’s most prolific architects. Recent research has helped to define Bennes’ place in the architectural history of Portland and Oregon, though new information about him continues to be uncovered. This presentation explores the rich architectural legacy that Bennes created and shares new information...
St. Lawrence Island, Alaska is home to two Formerly Used Defense Sites (FUDS) under remediation by the U.S. Army Corps of Engineers since 1985. After more than two decades the local residents continue to be concerned about inadequate site characterization and cleanup. During the summer of 2005, I collected ethnographic...
Studying human’s ability to estimate temporal durations could lead to a greater
understanding of our cognitive abilities as well as the processes that underlie temporal
estimation. It has been shown through previous research that time and number may be
interconnected cognitively and that the magnitude of one may alter the...
Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...
Controversy regarding moral development research has given rise to a proliferation of theories competing for acceptance. For all these researchers, the work of Lawrence Kohlberg is the pivot point for comparisons, contrasts, and discussions. Still, no theories to date adequately describe and document a theoretically complete conception of moral judgment...
Purpose of the Study: This study was undertaken as a result of interest in the
introduction of guide groups into the operation of secondary
schools. Particularly when viewed from the historical perspective
of the times in which it was initiated, the guide group concept
offers an opportunity to examine the...
