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...
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, ...
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...

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...
Diurnal cycling of glutathione in marine phytoplankton: Field and culture studies
glutathione marine phytoplankton Field culture
<
2014/5/19
Glutathione is an abundant intracellular thiol that is involved in the detoxification of reactive oxygen species generated in the presence of light. We used short-term continuous cultures of Emiliania...

molecular weight photosynthetic products marine phytoplankton early diagenesis
<
2014/5/14
Changes in the size and neutral aldose (NAld) composition of phytoplankton photosynthetic products during the early diagenetic process were experimentally examined using 13C as a tracer. Most (94.7%) ...
Experimental studies on the accumulation of polonium-210 by marine phytoplankton
accumulation of polonium-210 marine phytoplankton
<
2014/5/20
Bioaccumulation of polonium-210 (t1/2 = 138 d) in marine phytoplankton can introduce this naturally occurring radioisotope into food chains, where it accounts for most of the radiation dose to marine ...

Enhancement of marine phytoplankton blooms by appendicularian grazers
<
2014/5/20
Short-lived blooms of large phytoplankton are the main vector in the atmosphere-ocean-sediment carbon flux and are associated with high fish production. A common assumption is that grazing zooplankton...
