Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith S.
Abstract:: Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...

To Fill or Not to Fill: Sensitivity Analysis of the Influence of Resolution and Hole Filling on Point Cloud Surface Modeling and Individual Rockfall Event Detection

Creator:: Olsen, Michael J., Wartman, Joseph, McAlister, Martha, Mahmoudabadi, Hamid, O'Banion, Matt S., Dunham, Lisa, and Cunningham, Keith
Abstract:: Monitoring unstable slopes with terrestrial laser scanning (TLS) has been proven effective. However, end users still struggle immensely with the efficient processing, analysis, and interpretation of the massive and complex TLS datasets. Two recent advances described in this paper now improve the ability to work with TLS data acquired on...

Complex mountain terrain and disturbance history drive variation in forest aboveground live carbon density in the western Oregon Cascades, USA

Creator:: Zald, Harold S. J., Spies, Thomas A., Seidl, Rupert, Pabst, Robert J., Olsen, Keith A., and Steel, E. Ashley
Abstract:: Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...

Climate oscillations, glacial refugia, and dispersal ability: factors influencing the genetic structure of the least salmonfly, Pteronarcella badia (Plecoptera), in Western North America

Creator:: Sproul, John S., Houston, Derek D., Nelson, C. Riley, Evans, R. Paul, Crandall, Keith A., and Shiozawa, Dennis K.
Abstract:: Background: Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested...

Effects of Silviculture and Genetics on Branch/Knot Attributes of Coastal Pacific Northwest Douglas-Fir and Implications for Wood Quality—A Synthesis

Creator:: Lowell, Eini C., Maguire, Douglas A., Briggs, David G., Turnblom, Eric C., Jayawickrama, Keith J. S., and Bryce, Jed
Abstract:: Douglas-fir is the most commercially important timber species in the US Pacific Northwest due to its ecological prevalence and its superior wood attributes, especially strength and stiffness properties that make it highly prized for structural applications. Its economic significance has led to extensive establishment and management of plantations over the...

Trends in Caspian Tern Nesting and Diet in San Francisco Bay: Conservation Implications for Terns and Salmonids

Creator:: Collis, Ken, Roby, Daniel D., Larson, Keith W., Adrean, Lindsay J., Nelson, S. Kim, Evans, Allen F., Hostetter, Nathan, Battaglia, Dan, Lyons, Donald E., Marcella, Tim, and Patterson, Allison
Abstract:: Colony size, nesting ecology and diet of Caspian Terns (Hydroprogne caspia) were investigated in the San Francisco Bay area (SFBA) during 2003-2009 to assess the potential for conservation of the tern breeding population and possible negative effects of predation on survival of juvenile salmonids (Oncorhynchus spp.). Numbers of breeding Caspian...

A national survey of managed honey bee 2013-2014 annual colony losses in the USA

Creator:: Lee, Kathleen V., Steinhauer, Nathalie, Rennich, Karen, Wilson, Michael E., Tarpy, David R., Caron, Dewey M., Rose, Robyn, Delaplane, Keith S., Baylis, Kathy, Lengerich, Eugene J., Pettis, Jeff, Skinner, John A., Wilkes, James T., Sagili, Ramesh, and vanEngelsdorp, Dennis
Abstract:: Honey bee colony losses are a major concern in the USA and across the globe. Long-term data on losses are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter of 2006–2007. Here, we report the results from the eighth annual survey...
