Variability in brood size and female length of Euphausia pacifica among three populations in the North Pacific

Creator:: Gomez-Gutierrez, Jaime, Feinberg, Leah R., Shaw, Tracy, and Peterson, William T.
Abstract:: We compared brood sizes among adult female Euphausia pacifica Hansen, 1911 from 3 populations in the North Pacific: Puget Sound, Washington, USA; Toyama Bay, Japan; and the Oregon coast, USA. Additionally, we used multiple linear regression models to compare the interspecific brood size as a function of female length and...

Larval development of Euphausia pacifica in the laboratory: variability in developmental pathways

Creator:: Feinberg, Leah R., Shaw, C. Tracy, and Peterson, William T.
Abstract:: Gravid adult female Euphausia pacifica were collected off Newport, Oregon, USA and transferred to the laboratory, where females spawned eggs, eggs hatched, and larvae were reared at 10.5 degrees C. We fed 4 cohorts of larvae to excess with a combination of phytoplankton species and monitored them daily until they...

Egg production rates of the copepod Calanus marshallae in relation to seasonal and interannual variations in microplankton biomass and species composition in the coastal upwelling zone off Oregon, USA

Creator:: Peterson, William T. and Du, Xiuning
Abstract:: In this study, we assessed trophic interactions between microplankton and copepods by studying the functional response of egg production rates (EPR; eggs female⁻¹day⁻¹) of the copepod Calanus marshallae to variations in microplankton biomass, species composition and community structure. Female C. marshallae and phytoplankton water samples were collected biweekly at an...

Creator:: Batchelder, Harold P., Daly, Kendra L., Davis, Cabell S., Ji, Rubao, Ohman, Mark D., Peterson, William T., and Runge, Jeffrey A.
Abstract:: The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental controls on zooplankton vital rates, especially the timing and magnitude of reproduction, growth, life-cycle progression, and mortality, determine species population dynamics, seasonal and spatial distributions,...

Biological indicators of the timing and direction of warm-water advection during the 1997/1998 El Niño off the central Oregon coast, USA

Creator:: Keister, Julie E., Johnson, Travis B., Morgan, Cheryl A., and Peterson, William T.
Abstract:: Unusual collections of several euphausiid, chaetognath, and copepod species help elucidate the effects of the strong 1997/1998 El Niño off the central Oregon, USA, coast. Furcilia of Nyctiphanes simplex, a euphausiid typically found only as far north as central California, were collected in bi-weekly nearshore samples between December 1997 and...

A comparative analysis of coastal and shelf-slope copepod communities in the northern California Current system: Synchronized response to large-scale forcing?

Creator:: Bi, Hongsheng, Peterson, William T., Peterson, Jay O., and Fisher, Jennifer L.
Abstract:: The synchrony between coastal and shelf-slope copepod communities was investigated in the northern California Current (NCC) system, a strong upwelling zone, using time series of zooplankton sampled from a nearshore station (9 km offshore, water depth 62 m) and a shelf-slope station (46 km offshore, water depth 297 m). Long-term...

Onshore-offshore variations in copepod community structure off the Oregon coast during the summer upwelling season

Creator:: Morgan, Cheryl A., Peterson, William T., and Emmett, Robert L.
Abstract:: During the summer of 1994, 1996, and 1997, we conducted hydrographic and plankton surveys of the upper 70 m in the nearshore, the continental shelf, and off shelf oceanic waters off Oregon, USA. Copepod densities and biomass were estimated along 4 transects from each cruise. The on shelf copepod biomass...

Seasonal Cycle of Phytoplankton Community Composition in the Coastal Upwelling System Off Central Oregon in 2009

Creator:: Du, Xiuning and Peterson, William T.
Abstract:: Coastal upwelling in the northern California Current varies seasonally, with downwelling in winter and upwelling in summer, resulting in pronounced variability in hydrography, nutrients, phytoplankton biomass, and species composition. Winter was characterized by moderate concentrations of nitrate and silicate (averages of 10 and 18 μM, respectively) and low concentrations of...

The mitochondrial genomes of Euphausia pacifica and Thysanoessa raschii sequenced using 454 next-generation sequencing, with a phylogenetic analysis of their position in the Malacostracan family tree

Creator:: Johansson, Mattias L., Sremba, Angela L., Feinberg, Leah R., Banks, Michael A., and Peterson, William T.
Abstract:: Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...
