The sagebrush ecosystem, home to numerous plant and animal species including big sagebrush (Artemisia tridentata) and the endemic greater sage-grouse (Centrocercus urophasianus), has endured fragmentation and degradation of both quantity and quality due to the cumulative and synergistic relationships between an abundance of individual disturbances including grazing, invasive annuals and...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
This dissertation is situated as the third work in a series on academic women. In 1964,
Jessie Bernard published Academic Women, which provided a comprehensive
assessment of the status of women in academia. Two decades later, in 1987, Angela
Simeone offered insight into attempts to achieve equity for women in...
Current reforms in science education advocate instruction which capitalizes on broad,
integrative understandings of a few underlying concepts. Such recommendations imply
that science teachers already hold integrated conceptualizations and will use such
understandings to guide practice. However, little research exists which delineates the
global content understandings of biology teachers (herein...

During the eighteenth century, diagrams increasingly became an important aspect of scientific inquiry. Diagrams employed simplification as a strategy for representing complex information, played a role in standardizing scientific language, and served as instruments of reason to think through and communicate problems and findings in mathematics, physics, chemistry, astronomy, natural...
Land application of industrial wastewater with high levels of nitrogen requires
adequate management practices to prevent groundwater pollution by nitrates. In this study
a predictive computerized model was developed for nitrate leachate concentrations
resulting from land application of wastewater onto crop systems including poplars. The
study included a literature review,...
