Will wetlands restoration plans today still be effective tomorrow? Evaluation of performance of potential wetlands for peak flow reduction in future climate scenarios in the Eagle Creek Watershed, IN

Creator:: Walters, Kelli M.
Abstract:: Global climate change is expected to exaggerate the severity of floods and droughts and increase the frequency of extreme streamflow events in the Midwestern United States. Managing these projected impacts poses a major challenge for water resources, conservation, and land use management. Wetlands have been considered as a conservation strategy...

Biodiversity : illustrations of some concepts, causes, and consequences

Creator:: Russell, Roland B.
Abstract:: Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of ecological understanding. This work is my attempt at communicating both of these, in relation to three questions about our understanding of the structure and dynamics of biological diversity. These questions focus on a) advancing our understanding of...

Effects of pesticides on amphibians with special reference to the pyrethroidinsecticide, cypermethrin

Creator:: Biga, Lindsay M.
Abstract:: Pollution by pesticides is a ubiquitous concern for wildlife. The effects of pesticides are especially concerning in aquatic environments, which are particularly vulnerable as they have several exposure routes for the influx of chemicals. These effects are of particular concern as biodiversity loss reaches unprecedented rates. This includes recent declines...

Effects of tillage-induced soil compaction on carrot seedlings emergence and yield

Creator:: Thomasson, James E.
Abstract:: The effects of five tillage treatments on soil bulk density and mechanical impedance were examined on Newburg sandy loam soil in the Willamette Valley, Oregon, in 1987. Subsequent effects on seedling emergence and yield of carrots (Daucus carota L., cvs. Orlando Gold and Royal Chantenay) were also measured. Mechanical impedance...

The Art of Noticing : An Essay on Contemporary Ecological Writing

Creator:: West, Rex Alan, 1967-
Abstract:: A number of thinkers are becoming increasingly persuaded that our anthropocentric view of nature is inadequate, that we need a "new morality" with regard to the environment. In this essay, I argue that an alternative to anthropocentricism is available to us now-and has been since at least 1836. I look...

Relationships of clay mineralogy to landscape stability in Western Oregon

Creator:: Taskey, Ronald D. (Ronald David), 1944-
Abstract:: Soil erosion by mass wasting is the major problem on forest lands of the Pacific Northwest, The clay fractions of soils from a large number of sites in Oregon's Western Cascades were characterized in order to determine the relationships of various clay materials to mass movements. Each site was either...

A comparison of the effect of oral versus written lesson closure on the achievement of seventh and eighth grade students in social studies

Creator:: Rife, Carol Lee
Abstract:: This was an experimental study which compared two different instructional methods, oral lesson closure versus written lesson closure, on the achievement of 156 junior high school students in social studies. This study was composed of two duplicate experiments. Experiment I was conducted with 71 seventh grade social studies students at...

Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

Creator:: Urbina Gonzalez, Jenny Cecilia
Abstract:: This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...
