The imprint of coarse woody debris on soil biological and chemical properties in the western Oregon Cascades

Creator:

Spears, Julie D. H.

Abstract:

The abundance and spatial heterogeneity of coarse woody debris (CWD) on the forest floor is a prominent feature of Pacific Northwest (PNW) forest ecosystems. The effect of CWD on soil solution chemistry, nutrient cycling and availability, soil physical structure and formation of soil organic matter, however, remains unknown. Therefore, studies...

Characteristics of soil organic matter in two forest soils

Creator:

Crow, Susan E.

Abstract:

Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

Stream DOC, nitrate, chloride and SUVA response to land use during winter baseflow conditions in sub-basins of the Willamette River Basin, OR

Creator:

Frentress, Jay

Abstract:

To better understand the impact of land use on stream nutrient export, a synoptic sampling of 57 sub-basins within the Willamette River basin was conducted during winter baseflow conditions (February 2009). I assessed whether stream dissolved organic carbon (DOC), NO₃⁻ and Cl⁻ and specific ultra-violet absorbance (SUVA) values were correlated...
