The effect of pH on the uptake of zinc and cadmium in marine phytoplankton: Possible role of weak complexes
The effect of pH on the uptake zinc cadmium marine phytoplankton Possible role of weak complexes
2014/4/2
In natural samples from the New Jersey coast and the Gulf of Alaska, zinc (Zn) and cadmium (Cd) uptake rates by phytoplankton decreased on average about 30%as pH was decreased from 8.5 to 7.9 or 7.7, ...
Nickel limitation and zinc toxicity in a urea-grown diatom
Nickel limitation zinc toxicity urea-grown diatom
2014/4/21
When growing on urea as a nitrogen source, diatoms must accumulate nickel (Ni), a cofactor in the urease enzyme, which hydrolyzes urea. The uptake of Ni at low ambient concentrations is particularly c...
Zinc-cobalt colimitation of Phaeocystis antarctica
Zinc-cobalt colimitation Phaeocystis antarctica
2014/4/21
We present evidence demonstrating the capability of Phaeocystis antarctica colonies to substitute cobalt (Co) and zinc (Zn) as micronutrients, in which Co limitation is alleviated by additions of Zn a...

Iron and zinc enrichments in the northeastern subarctic Pacific: Ligand production and zinc availability in response to phytoplankton growth
Iron and zinc enrichments northeastern subarctic Pacific Ligand production and zinc availability response to phytoplankton growth
2014/5/13
Iron- and zinc-enrichment experiments were carried out at Ocean Station Papa in the subarctic North Pacific. In iron-enriched treatments, phytoplankton chlorophyll a (Chl a) increased 20-fold (9.7 μg ...
Effects of dissolved carbon dioxide, zinc, and manganese on the cadmium to phosphorus ratio in natural phytoplankton assemblages
Effects of dissolved carbon dioxide, zinc, and manganese the cadmium to phosphorus ratio natural phytoplankton assemblages
2014/5/9
We report the results of a field study, in productive waters off California, of the factors that control the particulate cadmium (Cd) : phosphorus (P) composition of natural assemblages of marine phyt...
Effect of CO2 supply and demand on zinc uptake and growth limitation in a coastal diatom
Effect of CO2 supply and demand zinc uptake growth limitation coastal diatom
2014/5/9
We conducted culture experiments with Thalassiosira pseudonana to determine the effect of CO2, photoperiod, and light intensity on cellular zinc concentrations and zinc requirements for growth. Cellul...
We present a budget for lead, zinc, and copper in Lough Neagh, Northern Ireland, and use the results from this and seven other lakes in Europe and the United States to develop two simple, generic mode...
Not all eucaryotic algae can replace zinc with cobalt: Chaetoceros calcitrans (Bacillariophyceae) versus Emiliania huxleyi
Not all eucaryotic algae replace zinc with cobalt Chaetoceros calcitrans Bacillariophyceae versus Emiliania huxleyi
2014/6/9
Zinc and cobalt are essential trace metals for phytoplankton growth and can substitute for each other metabolically in some eukaryotic algal species, especially in some marine diatoms and coccolithoph...
Bioavailability of particle-associated silver, cadmium, and zinc to the estuarine amphipod, Leptocheirus plumulosus, through dietary ingestion
Bioavailability particle-associated silver cadmium zinc to the estuarine amphipod Leptocheirus plumulosus dietary ingestion
2014/6/17
We conducted experiments to determine effects of particle type on assimilatory metal bioavailability to Leptocheirus plumulosus, an infaunal, estuarine amphipod that is commonly used in sediment toxic...
