Occurrence of demersal fishes in relation to near-bottom oxygen levels within the California Current large marine ecosystem

Creator:: Keller, Aimee A., Ciannelli, Lorenzo, Wakefield, W. Waldo, Simon, Victor, Barth, John A., and Pierce, Stephen D.
Abstract:: Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...

Ecological effects of alternative fuel-reduction treatments: highlights of the National Fire and Fire Surrogate study (FFS)

Creator:: McIver, James D., Stephens, Scott L., Agee, James K., Barbour, Jamie, Boerner, Ralph E. J., Edminster, Carl B., Erickson, Karen L., Farris, Kerry L., Fettig, Christopher J., Fiedler, Carl E., Haase, Sally, Hart, Stephen C., Keeley, Jon E., Knapp, Eric E., Lehmkuhl, John F., Moghaddas, Jason J., Otrosina, William, Outcalt, Kenneth W., Schwilk, Dylan W., Skinner, Carl N., Waldrop, Thomas A., Weatherspoon, C. Phillip, Yaussy, Daniel A., Youngblood, Andrew, and Zack, Steve
Abstract:: The 12-site National Fire and Fire Surrogate study (FFS) was a multivariate experiment that evaluated ecological consequences of alternative fuel-reduction treatments in seasonally dry forests of the US. Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire...

Recent pre-recruit Pacific hake (Merluccius productus) occurrences in the Northern California Current suggest a northward expansion of their spawning area

Creator:: Phillips, A. Jason, Ralston, Stephen, Brodeur, Richard D., Auth, Toby D., Emmett, Robert L., Johnson, Carrie, and Wespestad, Vidar G.
Abstract:: Coastal Pacific hake (Merluccius productus) are known to spawn in the southern California Bight from January to March, migrate north during late spring and summer to feed off Oregon, Washington, and British Columbia, and then move back to southern California in the fall. Juvenile Pacific hake nursery areas have been...

Physical versus biological spring transition: 2005

Creator:: Kosro, P. Michael, 1951-, Peterson, William T., Hickey, Barbara M., Shearman, R. Kipp, and Pierce, Stephen D.
Abstract:: In 2005, the onset of spring conditions in the physics of the coastal ocean (lowered sea level, spin-up of vertically-sheared equatorward coastal jet) came about 50 days later than average off Newport Oregon, on May 24. There was a further delay of 50 days before the subsurface upwelled water penetrated...

Evaluation of a Selective Flatfish Trawl and Diel Variation in Rockfish Catchability as Bycatch Reduction Tools in the Deepwater Complex Fishery off the U.S. West Coast

Creator:: Hannah, Robert W., Parker, Steven J., and Buell, Troy V.
Abstract:: We tested the potential of a selective flatfish trawl to reduce bycatch of slope rockfish in the upper continental slope bottom-trawl fishery (250–500 m) on the U.S. West Coast. The trawl we tested differed from typical slope trawls in that it was a low-rise, two-seam trawl with a severely cut...

Effects of maternal age on reproductive success in black rockfish, Sebastes melanops

Creator:: Bobko, Stephen J.
Abstract:: From 1996 through 1998 I collected mature female black rockfish off Oregon and examined ovaries and otoliths to estimate weekly, age-specific larval production. In all reproductive seasons, older black rockfish extruded larvae earlier in the season, followed by progressively younger fish. Each year, beginning in May, I collected young-of-the-year (YOY)...
