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...

Competitive Interactions and Resource Partitioning Between Northern Spotted Owls and Barred Owls in Western Oregon

Creator:: Wiens, J. David, Anthony, Robert G., and Forsman, Eric D.
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

Estimating heterotrophic respiration at large scales: challenges, approaches, and next steps

Creator:: Bond-Lamberty, Ben, Epron, Daniel, Harden, Jennifer, Harmon, Mark E., Hoffman, Forrest, Kumar, Jitendra, David McGuire, Anthony, and Vargas, Rodrigo
Abstract:: Heterotrophic respiration (HR), the aerobic and anaerobic processes mineralizing organic matter, is a key carbon flux but one impossible to measure at scales significantly larger than small experimental plots. This impedes our ability to understand carbon and nutrient cycles, benchmark models, or reliably upscale point measurements. Given that a new...

Barred Owls and Landscape Attributes Influence Territory Occupancy of Northern Spotted Owls

Creator:: Sovern, Stan G., Forsman, Eric D., Olson, Gail S., Biswell, Brian L., Taylor, Margaret, and Anthony, Robert G.
Abstract:: We used multi-season occupancy analyses to model 2 fates of northern spotted owl territories in relation to habitat amount, habitat fragmentation, and the presence of barred owls in Washington State, USA, 1989–2005. Local colonization is the probability a territory unoccupied by a spotted owl in year i would be occupied...

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:: Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.
Abstract:: Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...

Which design elements of individual quota fisheries help to achieve management objectives?

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., and Smith, Anthony D. M.
Abstract:: Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...

Catch shares, fisheries, and ecological stewardship: a comparative analysis of resource responses to a rights-based policy instrument

Creator:: Essington, Timothy E., Melnychuk, Michael C., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Rights-based approaches are potentially promising tools to meet conservation objectives in natural resource management. Here, we evaluated how population status and fishery production respond to catch shares, a rights-based policy instrument in fisheries whereby participants are granted a right to harvest a fraction of the allowable catch. By analyzing time...

Demographic response of northern spotted owls to barred owl removal

Creator:: Diller, Lowell V., Hamm, Keith A., Early, Desiree A., Lamphear, David W., Dugger, Katie M., Yackulic, Charles B., Schwarz, Carl J., Carlson, Peter C., and McDonald, Trent L.
Abstract:: Federally listed as threatened in 1990 primarily because of habitat loss, the northern spotted owl (Strix occidentalis caurina) has continued to decline despite conservation efforts resulting in forested habitat being reserved throughout its range. Recently, there is growing evidence the congeneric invasive barred owl (Strix varia) may be responsible for...

Examining Student Research Choices and Processes in a Disintermediated Searching Environment

Creator:: Rempel, Hannah, Buck, Stefanie, and Deitering, Anne-Marie
Abstract:: Students today perform research in a disintermediated environment, which often allows them to struggle directly with the process of selecting research tools and choosing scholarly sources. The authors conducted a qualitative study with twenty students, using structured observations to determine the processes students use to select databases and choose sources...

Roosting Habitat Use and Selection By Northern Spotted Owls During Natal Dispersal

Creator:: Sovern, Stan G., Forsman, Eric D., Dugger, Katie M., and Taylor, Margaret
Abstract:: We studied habitat selection by northern spotted owls (Strix occidentalis caurina) during natal dispersal in Washington State, USA, at both the roost site and landscape scales. We used logistic regression to obtain parameters for an exponential resource selection function based on vegetation attributes in roost and random plots in 76...
