Abstract:: Semi-volatile trace metals (e.g., Cd, Sn, Pb, Zn, Cu, Mo) have been analyzed by using laser ablation ICP-MS in a number of silicate glasses (GSE-1G, GSD-1G, NIST 610, NIST 612, BCR-2G, BHVO-2G). Our work investigates and highlights sources of uncertainty in the analysis of semi-volatile metals using LA-ICP-MS. We identify...

The cultural significance of mountain regions : implications for the Calapooya Divide, Oregon

Creator:: Starr, Karen J.
Abstract:: Altitudinal variations in upland regions of the earth create variable climatic zones and conditions. Plant and animal communities must adapt to these conditions, and when they reach their tolerance limits for environmental conditions at the upper levels of a zone, they cease to exist in the environment. Humans also utilize...

Headwater Dynamics: Quantifying Spatial Differences in Flow Permanence and Network Connectivity across Diverse Landscapes

Creator:: Pate, Adam A.
Abstract:: Forested headwater streams are critical for the supply of water, sediment, nutrients, and organic matter to downstream water bodies. Nearly half of all headwater streams display temporary flow regimes (i.e., non-perennial), but with climate change they may become more common. Thus, it will be increasingly imperative to adequately represent non-perennial...

Multi-temporal LiDAR Analysis of Landscape Fire Effects in Southwestern Oregon

Creator:: Hoe, Michael
Abstract:: Quantitative assessments of post-fire effects are key to improving our understanding of ecosystem resilience. While remote sensing technology has allowed us to assess post-fire landscape effects, we are often limited by the lack of information related to pre-fire forest attributes. As a result, our ability to interpret fire effects in...
