Experiments were performed to determine the rate of recolonization of sediment-associated microalga and effects of infauna on microalgal biomass and production. Estuarine sediment was defaunated and transplanted to the field and the laboratory. Recolonization of sediment by flora and fauna, relative to control sediment, was measured by chlorophyll a, gross...
The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To better understand present temperature regimes, we assembled a 29-year nearshore time series of mean monthly...
Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...
Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...
The organization and operation of a successful fishery cooperative requires a knowledge and understanding of cooperative management and marketing concepts.
This publication provides information about cooperative organization, management, and legal instruments used in organizing and operating a cooperative. It is available in two parts. This portion, part one, provides an...
For this trial, established Pinot noir vines, located on the valley floor of the Umpqua Valley in Oregon
were used. In 1996 and 1997 sixteen vines trained to the Scott Henry trellising system were separated
into four different quadrants, determined by shoot orientation: Bottom canopy, shoots trained toward the
ground;...
This is one in a series of pollen studies of post-Pleistocene peat and other pollen-bearing sediments in the Pacific Northwest. Bogs in British Columbia, northern Idaho, many parts of Washington, and in west central Oregon have been analyzed and the forest succession interpreted from the pollen profiles. A tentative climatic...
Isopycnal slope spectra were computed from thermistor data obtained using a microstructure platform
towed through turbulence generated by internal tidal motions near the Hawaiian Ridge. The spectra were
compared with turbulence dissipation rates ε that are estimated using shear probes. The turbulence subrange
of isopycnal slope spectra extends to surprisingly...
The potent antitumor agent phorboxazole A was synthesized from six subunits comprising C1-C2 (115), C3-C8 (98), C9-C19 (74), C20-C32 (52), C33-C41 (84) and C42-C46 (85). Tetrahydropyrans B and C containing cis-2,6-disubstitution were fabricated via palladium(II)-mediated intramolecular alkoxycarbonylation which, in the case of tetrahydropyran C, was carried out with catalytic palladium(II)...
Pretreatment of male C57BL/6 mice with low doses of the persistent organochlorine
(OC) pesticide, chlordecone (CD), stimulated biliary excretion of exogenous CH up to 3-fold. Increased biliary excretion occurred without changes in hepatic ATP-binding
cassette transporter G8 (ABCG8) of the bile canaliculus or scavenger receptor class B
type I (SR-BI)...
