Measurement of Gas Exchange, Stream Metabolism, and Carbon Fluxes of Headwater Streams

Creator:: Pennington, Robert S.
Abstract:: Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...

Lava Flow Lobation and Margin Analysis

Creator:: Peckyno, Robert S.
Abstract:: Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...

Site Fidelity and Movement of Eight Species of Pacific Rockfish at a High-Relief Rocky Reef on the Oregon Coast

Creator:: Hannah, Robert W. and Rankin, Polly S.
Abstract:: We used acoustic telemetry techniques to study the movements of eight species of Pacific rockfish (genus Sebastes) inhabiting Siletz Reef, a high-relief rocky reef complex on the Oregon coast. Our primary interest was evaluating potential residence times for rockfish species in small, no-take marine protected areas (MPAs) like those recently...

Thinning and in-stream wood recruitment in riparian second growth forests in coastal Oregon and the use of buffers and tree tipping as mitigation

Creator:: Benda, Lee E., Litschert, S. E., Reeves, Gordon, and Pabst, Robert
Abstract:: Many aquatic habitats in coastal Oregon have been impacted by historic land use practices that led to losses of in-stream wood and associated degraded fish habitats. Many of these streams are now bordered by stands of dense second growth forests (30–80 years) that are incorporated into riparian buffer zones with...

Quantification of Habitat and Community Relationships among Nearshore Temperate Fishes Through Analysis of Drop Camera Video

Creator:: Easton, Ryan R., Heppell, Selina S., and Hannah, Robert W.
Abstract:: Temperate nearshore reefs along the Pacific coast of North America are highly valuable to commercial and recreational fisheries yet comprise a small fraction of the seabed. Monitoring fisheries resources in this region is difficult; high-relief structural complexity and adverse sea conditions have led to a paucity of information on temperate...

Survival Rates of Northern Spotted Owls in Post-fire Landscapes of Southwest Oregon

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: We estimated annual survival rates (S) of 23 radio-marked Northern Spotted Owls (Strix occidentalis caurina) at the Quartz and Timbered Rock burns and adjacent areas in southwest Oregon. We used known-fate models in program MARK to test for differences in survival among three groups (owls dwelling inside of burned areas,...

The divergent effect of capture depth and associated barotrauma on post-recompression survival of canary (Sebastes pinniger) and yelloweye rockfish (S. ruberrimus)

Creator:: Hannah, Robert W., Rankin, Polly S., and Blume, Matthew T. O.
Abstract:: We evaluated the external signs of barotrauma and 48-h post-recompression survival for 17 54 canary and 81 yelloweye rockfish captured at depths of 46-174 m, much deeper than a 18 similar prior experiment, but within the depth range of recreational fishery catch and 19 discard. Survival was measured using specialized...

Millennial slip rates of the Tazang fault, the eastern termination of Kunlun fault: implications for strain partitioning in eastern Tibet

Creator:: Ren, Junjie, Xu, Xiwei, Yeats, Robert S., and Zhang, Shimin
Abstract:: The way of slip transformation and strain partitioning at the eastern termination of the Kunlun fault system remains unclear, and the question of whether this fault system is an important part for lateral extrusion of Tibetan crust is debatable. The Tazang fault is regarded as the easternmost continuation of the...

Value Chain of Snakehead Fish in the Lower Mekong Basin of Cambodia and Vietnam

Creator:: Sinh, Le Xuan, Navy, Hap, and Pomeroy, Robert S.
Abstract:: Capture fisheries and aquaculture in freshwater bodies play a very important role and is considered to have great potential for augmenting fish production as well as diversification of livelihoods in both Cambodia and Vietnam. In Cambodia, inland fisheries remain primary importance in the fisheries sector, while aquaculture is more important...

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...
