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, ...
The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
The isotope composition of zinc (Zn) was determined in settling particles collected monthly over a year in the hypolimnion of the eutrophic Lake Greifen (Switzerland) in order to explore the potentia...
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...
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...

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...
We investigate the interreplacement of Zn, Cd, and Co in the cosmopolitan coccolithophore Emiliania huxleyi by examining its growth rate, cellular metal quotas, and cellular metal uptake rates under ...
Zinc (Zn) serves as a cofactor in several extracellular phosphatases, which allow microorganisms to acquire phosphorus from organic P compounds. In oligotrophic ocean water, where both phosphate and ...
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 ...
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...
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...
Cultures of the ubiquitous coccolithophore Emiliania huxleyi grown at field-relevant fixed free ion concentrations of Cu, Cd, and Zn exude a broad array of thiols, some of which increase with increasi...
A model for lead, zinc, and copper in lakes     model   lead  zinc  copper  lakes       2014/5/19
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...
We conducted culture experiments with the diatom Thalassiosira pseudonana to determine the interactive effects of day length and biologically available concentrations of iron and zinc on cellular iro...
