Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:

Miller, Todd William

Abstract:

The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

Young-of-the-year rockfish (Sebastes spp.) settlement dynamics in Oregon estuaries

Creator:

Abstract:

In the Pacific Northwest, several species of rockfishes (Sebastes spp.) are under extreme conservation measures due to low population levels. Although currently at healthy population levels, one species of interest is the black rockfish (S. melanops), which has been shown to utilize estuarine habitat during its early life history stages....
