Relationship between oceanic mesozooplankton and energy of eddy fields

Creator:: Piontkovski, S. A., Williams, R., Peterson, William T., and Kosnirev, V. K.
Abstract:: The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...

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...

Beached birds and physical forcing in the California Current System

Creator:: Parrish, Julia K., Bond, Nicholas, Nevins, Hannah, Mantua, Nathan, Loeffel, Robert, Peterson, William T., and Harvey, James T.
Abstract:: Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3...

Marine environment-based forecasting of coho salmon (Oncorhynchus kisutch) adult recruitment

Creator:: Rupp, David E., Wainwright, Thomas C., Lawson, Peter W., and Peterson, William T.
Abstract:: Generalized additive models (GAMs) were used to investigate the relationships between annual recruitment of natural coho salmon (Oncorhynchus kisutch) from Oregon coastal rivers and indices of the physical ocean environment. Nine indices were examined, ranging from large-scale ocean indicators, e.g., Pacific Decadal Oscillation (PDO), to indicators of the local ecosystem...

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...

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...

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...

Errors in juvenile copepod growth rate estimates are widespread: problems with the Moult Rate method

Creator:: Hirst, A. G., Peterson, William T., and Rothery, P.
Abstract:: The Moult Rate (MR) method has been used widely to derive stage-specific growth rates in juvenile copepods. It is the most common field-based method. Unfortunately, the equation underlying the method is wrong and, consequently, large errors in juvenile growth rate estimates are widespread. The equation derives growth from the mean...

Winter ichthyoplankton biomass as a predictor of early summer prey fields and survival of juvenile salmon in the northern California Current

Creator:: Daly, Elizabeth A., Auth, Toby D., Brodeur, Richard D., and Peterson, William T.
Abstract:: Diets of juvenile coho Oncorhynchus kisutch and Chinook O. tshawytscha salmon are made up primarily of winter-spawning fish taxa in the late-larval and early juvenile stages that are undersampled in plankton and larger trawl nets. Although we have no direct measure of the availability of fish prey important to juvenile...

Climate shifts the interaction web of a marine plankton community

Creator:: Francis, Tessa B., Scheuerell, Mark D., Brodeur, Richard D., Levin, Phillip S., Ruzicka, James J., Tolimieri, Nick, and Peterson, William T.
Abstract:: Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive...
