The interactive effects of calcium concentration and temperature on the survival and reproduction ofDaphnia pulexat high and low food concentrations
calcium concentration temperature on the survival Daphnia pul exat high low food concentrations
2014/4/21
We rearedDaphnia pulexin a fully defined medium at seven calcium (Ca) concentrations (0.1, 0.5, 1, 1.5, 2, 5, and 10 mg Ca L21), two mixed algal densities (high food: 30mg chlorophyllaL21 and low food...
The effect of seawater CO2 concentration on growth of a natural phytoplankton assemblage in a controlled mesocosm experiment
seawater CO2 concentration natural phytoplankton assemblage controlled mesocosm experiment
2014/5/4
We examine the effects of seawater pCO2 concentration of 25, 41, and 76 kPa (250, 400, and 750 matm) on the growth rate of a natural assemblage of mixed phytoplankton obtained from a carefully control...
The effect of growth rate, phosphorus concentration, and temperature on N2 fixation, carbon fixation, and nitrogen release in continuous cultures of Trichodesmium IMS101
growth rate phosphorus concentration temperature on N2 fixation carbon fixation nitrogen release continuous cultures Trichodesmium IMS101
2014/5/9
With the use of continuous culture systems, rates of dinitrogen (N2) and carbon (C) fixation and nitrogen (N)- and C-based doubling times were assessed in Trichodesmium IMS101 growing exponentially at...
Testing the direct effect of CO2 concentration on a bloom of the coccolithophorid Emiliania huxleyi in mesocosm experiments
CO2 concentration coccolithophore Emiliania huxleyi mesocosm experiments
2014/5/9
We studied the direct effects of CO2 and related changes in seawater carbonate chemistry on marine planktonic organisms in a mesocosm experiment. In nine outdoor enclosures (~11 m3 each), the partial ...
Transmission of oxygen concentration fluctuations through the diffusive boundary layer overlying aquatic sediments
oxygen concentration fluctuations diffusive boundary layer aquatic sediments
2014/5/14
Even though the O2 concentration in the diffusive boundary layer overlying natural aquatic sediments usually varies over time, microprofiles with little or no error bars are abundant in the literature...
Variation in iron(III) solubility and iron concentration in the northwestern North Pacific Ocean
Variation in iron(III) solubility iron concentration northwestern North Pacific Ocean
2014/5/27
Vertical distributions of Fe(III) hydroxide solubilities (<0.025 μm) and dissolved Fe (<0.2 μm) concentrations at 0-250 m depth were studied inside (HP) and outside (LP) a high-production (phytoplankt...
Interactive effect of temperature and food concentration on growth rate: A test case using the small freshwater ciliate Urotricha farcta
temperature and food concentration growth rate small freshwater ciliate Urotricha farcta
2014/5/26
The combined effect of temperature and food concentration on the growth rate, cell volume, and production of the freshwater ciliate Urotricha farcta was investigated in laboratory batch cultures. Expe...
Landscape variation in phosphorus concentration and effects on detritus-based tropical streams
Landscape variation phosphorus concentration on detritus-based tropical streams
2014/5/26
Landscape-scale variation in streamwater phosphorus (P) concentration can affect aquatic food webs. Such variation occurs naturally in streams at La Selva Biological Station in Costa Rica due to spati...
Large variability in the concentration of mycosporine-like amino acids among zooplankton from lakes located across an altitude gradient
Large variability in the concentration mycosporine-like amino acids located across an altitude gradient
2014/6/9
The qualitative and quantitative composition of mycosporine-like amino acids (MAAs), a family of intracellular UV-absorbing compounds, were investigated in zooplankton from 15 lakes located in the Cen...
