Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

The Fishery Performance Indicators: A Management Tool for Triple Bottom Line Outcomes

Creator:: Anderson, James L., Anderson, Christopher M., Chu, Jingjie, Meredith, Jennifer, Asche, Frank, Sylvia, Gil, Smith, Martin D., Anggraeini, Dessy, Arthur, Robert, Guttormsen, Atle, McCluney, Jessica K., Ward, Tim, Akpalu, Wisdom, Eggert, Håkan, Flores, Jimely, Freeman, Matthew A., Holland, Daniel S., Knapp, Gunnar, Kobayashi, Mimako, Larkin, Sherry, MacLauchlin, Karl, Shnier, Kurt, Soboli, Mark, Tveteras, Sigbjorn, Uchida, Hirotsugu, and Valderrama, Diego
Abstract:: Pursuit of the triple bottom line of economic, community and ecological sustainability has increased the complexity of fishery management; fisheries assessments require new types of data and analysis to guide science-based policy in addition to traditional biological information and modeling. We introduce the Fishery Performance Indicators (FPIs), a broadly applicable...

Attached and unattached bacterial communities in a 120-meter corehole in an acidic, crystalline rock aquifier

Creator:: Lehman, R. Michael, Roberto, Francisco F., Early, Drummond, Bruhn, Debby F., Brink, Susan E., O'Connell, Sean P., Delwiche, Mark. E, and Colwell, Frederick
Abstract:: The bacteria colonizing geologic core sections (attached) were contrasted with those found suspended in the groundwater (unattached) by examining the microbiology of 16 depth-paired core and groundwater samples using a suite of culture-independent and culture-dependent analyses. One hundred twenty-two meters was continuously cored from a buried chalcopyrite ore hosted in...

A Polynomial Equation for the Natural Earth Projection

Creator:: Savric, Bojan, Jenny, Bernhard, Patterson, Tom, Petrovic, Dusan, and Hurni, Lorenz
Abstract:: The Natural Earth projection is a new projection for representing the entire Earth on small-scale maps. It was designed in Flex Projector a specialized software application that offers a graphical approach for the creation of new projections. The original Natural Earth projection defines the length and spacing of parallels in...

Automated quantification of distributed landslide movement using circular tree trunks extracted from terrestrial laser scan data

Creator:: Conner, Jeremy C. and Olsen, Michael J.
Abstract:: This manuscript presents a novel algorithm to automatically detect landslide movement in a forested area using displacements of tree trunks distributed across the landslide surveyed repeatedly using terrestrial laser scanning (TLS). Common landslide monitoring techniques include: inclinometers, global position system (GPS), and interferometric synthetic aperture radar (InSAR). While these techniques...

Geo-Referenced, Abundance Calibrated Ocean Distribution of Chinook Salmon (Oncorhynchus tshawytscha) Stocks across the West Coast of North America

Creator:: Bellinger, M. Renee, Banks, Michael A., Bates, Sarah J., Crandall, Eric D., Garza, John Carlos, Sylvia, Gil, and Lawson, Peter W.
Abstract:: Understanding seasonal migration and localized persistence of populations is critical for effective species harvest and conservation management. Pacific salmon (genus Oncorhynchus) forecasting models predict stock composition, abundance, and distribution during annual assessments of proposed fisheries impacts. Most models, however, fail to account for the influence of biophysical factors on year-to-year...

Flow and transport when scales are not separated: Numerical analysis and simulations of micro- and macro-models

Creator:: Peszynska, Malgorzata, Showalter, Ralph E., and Yi, Son -Young
Abstract:: In this paper, we consider an upscaled model describing the multiscale flow of a single-phase incompressible fluid and transport of a dissolved chemical by advection and diffusion through a heterogeneous porous medium. Unlike traditional homogenization or volume averaging techniques, we do not assume a good separation of scales. The new...

Evaluation of Remediation Techniques for Circular Holes in the Webs of Wood I-Joists

Creator:: Polocoser, Tiberiu, Miller, Thomas H., and Gupta, Rakesh
Abstract:: Remediation methods and strength predictions were evaluated for wood I-joists with single, circular holes in the webs, leaving utilities in place. A full-scale bending test using four equally-spaced point loads was applied to three depths of joists with varying flange widths and span lengths of 4.88 m and 2.44 m....

Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
