Creator:: Garrison, Stacey L.
Abstract:: Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...

Creator:: Kish, Stacy W.
Abstract:: The increase in modern atmospheric CO₂ concentration (360 ppm) from pre-industrial levels (280 ppm) raises concern over the impact of anthropogenic carbon dioxide input on atmospheric chemistry. For this reason, it is important to understand the natural fluctuations of atmospheric carbon dioxide in the past. The Vostok ice core record...

Creator:: Taylor, Sara M.
Abstract:: Native prairies of the Willamette Valley are considered among the rarest of Oregon's ecosystems (Clark and Wilson, 2001).
