The effect of pH on the uptake of zinc and cadmium in marine phytoplankton: Possible role of weak complexes
zinc cadmium weak complexes
2014/4/4
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...
Does warming enhance the effect of microzooplankton grazing on marine phytoplankton in the ocean?
warming enhance the effect of microzooplankton grazing marine phytoplankton in the ocean
2014/4/2
We evaluated a hypothesis derived from the metabolic theory of ecology (MTE) that the ratio of microzooplankton herbivory (m) to phytoplankton growth (m) will arise in a warming ocean because of the d...

Dispersal, eddies, and the diversity of marine phytoplankton
plankton biodiversity hotspots
2014/4/1
We examined the role of physical dispersal in regulating patterns of diversity of marine phytoplankton in
the context of global ocean simulations at eddy-permitting and coarse resolutions. Swifter cu...
Reduction of dimethylsulfoxide to dimethylsulfide by marine phytoplankton
dimethylsulfoxide dimethylsulfide marine phytoplankton
2014/4/18
Dimethylsulfoxide (DMSO) is an abundant but poorly understood methylated sulfur compound in the marine environment. One potentially significant loss pathway for DMSO is through its biological reductio...
Production of chromophoric dissolved organic matter by marine phytoplankton
chromophoric dissolved organic matter marine phytoplankton
2014/4/16
Incubation experiments with axenic cultures of four common phytoplankton species of the generaChaetoceros,Skeletonema, Prorocentrum, and Micromonaswere performed to test for the production of fluoresc...
Resource levels, allometric scaling of population abundance, and marine phytoplankton diversity
Resource levels allometric scaling population abundance marine phytoplankton diversity
2014/4/21
We analyzed the relationship between population abundance and cell size in phytoplankton assemblages from coastal, shelf, and open-ocean environments. Our results show that across the entire size spec...
Predicting marine phytoplankton maximum growth rates from temperature:Improving on the Eppley curve using quantile regression
marine phytoplankton maximum growth rates temperature:Improving the Eppley curve quantile regression
2014/4/21
The Eppley curve describes an exponential function that defines the maximum attainable daily growth rate of marine phytoplankton as a function of temperature. The curve was originally fitted by eye as...

Phylogenetic diversity in cadmium : phosphorus ratio regulation by marine phytoplankton
Phylogenetic diversity cadmium phosphorus ratio regulation marine phytoplankton
2014/4/22
We examined the effect of irradiance and growth rate on cadmium : phosphorus ratio in five species of phytoplankton representing four different phylogenetic groups to determine the relative importance...
Ammonium uptake and growth limitation in marine phytoplankton
Ammonium uptake growth limitation marine phytoplankton
2014/4/21
We used continuous culture techniques and a sensitive fluorescence method to quantify relationships among ammonium (NH4+) concentration, cellular NH4+ uptake rates, and growth rate limitation for five...

elemental stoichiometry marine phytoplankton
2014/5/5
We analyzed the elemental composition (C, N, P, S, K, Mg, Ca, Sr, Fe, Mn, Zn, Cu, Co, Mo, and Ni) of five
marine phytoplankton species representing the four major marine phyla grown over a range of g...
Responses of estuarine and coastal marine phytoplankton to nitrogen and phosphorus enrichment
estuarine coastal marine phytoplankton
2014/4/30
A cross-ecosystem comparison of data obtained from 92 coastal zone ecosystems worldwide revealed a strong
positive response of marine phytoplankton biomass to nutrient enrichment that is highly consi...

2014/4/23
We investigated the carbon acquisition of three marine microalgae, Skeletonema costatum, Phaeocystis globosa,
and Emiliania huxleyi in response to different light regimes. Rates of photosynthetic O2
