Monitoring Approaches for Early Warning of Domoic Acid Events in Washington State
Monitoring Approaches Early Warning Domoic Acid Events Washington State
2015/7/27
On the U.S. west coast, blooms of the potentially toxic diatom Pseudo-nitzschia can cause amnesic shellfish poisoning (ASP), resulting in economic impacts to coastal economies and public health concer...
HANDS-ON OCEANOGRAPHY | Corals on Acid: An Inquiry-based Activity Leading Students to a Better Understanding of Ocean Acidification Impacts
Ocean sea creatures calcification invertebrate animal bones calcium carbonate
2015/7/16
The objective of this inquiry-based lesson is for students to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms. During this activity, students: (1...
Influence of bottom water anoxia on nitrogen isotopic ratios and amino acid contributions of recent sediments from small eutrophic Lonar Lake, central India
nitrogen isotopic ratios Influence
2014/4/2
Lonar Lake is a eutrophic, saline soda lake with permanently anoxic deep water. The high pH and
deoxygenation result in very elevated d15N of suspended particulate matter (SPM) and sediments due to
...
Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...

Temperature- and cholesterol-induced changes in eicosapentaenoic acid limitation of Daphnia magnadetermined by a promising method to estimate growth saturation thresholds
Temperature cholesterol-induced changes in eicosapentaenoic acid limitation Daphnia magnadetermined a promising method estimate growth saturation thresholds
2014/4/8
We present data on eicosapentaenoic acid (EPA)-limited growth responses ofDaphnia magnaunder different temperatures and different dietary cholesterol availabilities to assess how EPA growth saturation...
No limit? The multiphasic uptake of silicic acid by benthic diatoms
No limit multiphasic uptake silicic acid benthic diatoms
2014/4/18
Silicic-acid uptake kinetics for a field population of benthic diatoms were examined using a radioisotope tracer over a concentration range of 0–300mmol L21. The microphytobenthos half saturation cons...
Limiting levels of eicosapentaenoic acid: What do we really know?
Limiting levels eicosapentaenoic acid
2014/4/16
We thank Michael Brett for his thought-provoking comments on our original paper from almost 5 yr ago on the differential effects of phosphorus and fatty acids on Daphnia magnagrowth and reproduction (...
Autochthonous and allochthonous contributions to mesozooplankton diet in a tidal river and estuary: Integrating carbon isotope and fatty acid constraints
Autochthonous allochthonous contributions
2014/4/17
We examined the carbon sources used by bacteria and mesozooplankton in the Scheldt River and estuary
(Belgium, The Netherlands) using a combined stable isotope and fatty acid composition approach. Wa...
Variability of Pseudo-nitzschia and domoic acid in the Juan de Fuca eddy region and its adjacent shelves
Pseudo-nitzschia and domoic acid adjacent shelves
2014/4/17
The Juan de Fuca eddy is a toxic ‘‘hot spot.’’ Domoic acid (DA) was detected in the eddy during each of six
cruises over a 4-yr study, although Pseudo-nitzschia abundance and toxin concentrations wer...
Effect of light and feeding on the fatty acid and sterol composition of zooxanthellae and host tissue isolated from the scleractinian coral Turbinaria reniformis
Effect of light and feeding on the fatty acid sterol composition of zooxanthellae host tissue isolated scleractinian coral Turbinaria reniformis
2014/4/21
The fatty acid and sterol compositions of zooxanthellae and animal fractions of the scleractinian coral Turbinaria reniformis were investigated under different light and feeding conditions, to study t...
The role of organic acid exudates in liberating phosphorus from seagrass-vegetated carbonate sediments
The role of organic acid exudates liberating phosphorus seagrass-vegetated carbonate sediments
2014/4/21
Sediment-bound phosphorus (P) is a potential nutrient source for P-limited seagrasses inhabiting carbonate sediments. We explored the role of organic acid (OA) exudation by seagrasses in liberating mi...
Is w6 docosapentaenoic acid an essential fatty acid during early ontogeny in marine fauna?
w6 docosapentaenoic acid essential fatty acid during early ontogeny marine fauna
2014/4/22
A thraustochytrid marine protist (Schizochytrium sp.) was fed to rotifers (Branchionus plicatilis), which in turn, were fed to cod larvae (Gadus morhua). Samples of larvae 1 and 11 d after hatch, the ...
