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...

Vicarious calibration of the Ocean PHILLS hyperspectral sensor using a coastal tree-shadow method

Creator:: Filippi, Anthony M., Carder, Kendall L., and Davis, Curtiss O.
Abstract:: Ocean color remote-sensing systems require highly accurate calibration (<0.5%) for accurate retrieval of water properties. This accuracy is typically achieved by vicarious calibration which is done by comparing the atmospherically corrected remote-sensing data to accurate estimates of the water-leaving radiance. Here we present a new method for vicarious calibration of...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

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 sources of volatile and fluid-mobile elements in the Sunda arc: A melt inclusion study from Kawah Ijen and Tambora volcanoes, Indonesia

Creator:: Vigouroux, Nathalie, Wallace, Paul J., Williams-Jones, Glyn, Kelley, Katherine, Kent, Adam J. R., and Williams-Jones, Anthony E.
Abstract:: Subduction zone recycling of volatiles (H₂O, Cl, S, F) is controlled by the nature of subducted materials and the temperature-pressure profile of the downgoing slab. We investigate the variability in volatile and fluid-mobile trace element enrichment in the Sunda arc using melt inclusion data from Kawah Ijen and Tambora volcanoes,...

Mapping tropical Pacific sea level: Data assimilation via a reduced state space Kalman filter

Creator:: Cane, Mark A., Kaplan, Alexey, Miller, Robert N., Tang, Benyang, Hackert, Eric C., and Busalacchi, Anthony J.
Abstract:: The well-known fact that tropical sea level can be usefully simulated by linear wind driven models recommends it as a realistic test problem for data assimilation schemes. Here we report on an assimilation of monthly data for the period 1975-1992 from 34 tropical Pacific tide gauges into such a model...

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...

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...

Paleomagnetism of the southwestern U.S.A. recorded by 0-5 Ma igneous rocks

Creator:: Tauxe, Lisa, Constable, Catherine, Johnson, Catherine L., Koppers, Anthony A. P., Miller, Winter R., and Staudigel, Hubert
Abstract:: The issue of permanent nondipole contributions to the time-averaged field lies at the very heart of paleomagnetism and the study of the ancient geomagnetic field. In this paper we focus on paleomagnetic directional results from igneous rocks of the southwestern U.S.A. in the age range 0–5 Ma and investigate both...

Hydrothermal venting at Vailulu'u Seamount: The smoking end of the Samoan chain

Creator:: Staudigel, H., Hart, Stanley R., Koppers, Anthony A. P., Constable, C., Workman, R., Kurz, M., and Baker, E. T.
Abstract:: The summit crater of Vailulu’u Seamount, the youngest volcano in the Samoan chain, hosts an active hydrothermal system with profound impact on the ocean water column inside and around its crater (2 km wide and 407 m deep at a 593 m summit depth). The turbidity of the ocean water...
