Incorporation of nitrogen from N2 fixation into amino acids of zooplankton
zooplankton nitrogen
2014/4/4
Eurytemora affinis (Copepoda) were fed 15N-labeled Rhodomonas salina (Cryptophyta) or 15N-labeled
Nodularia spumigena (Cyanobacteria) in excess under controlled laboratory conditions. Zooplankton col...
Importance of N2 fixation vs. nitrate eddy diffusion along a latitudinal transect in the Atlantic Ocean
the Atlantic Ocean nitrate eddy
2014/4/8
We present ocean, basin-scale simultaneous measurements of N2-fixation, nitrate diffusion, and primary
production along a south–north transect in the Atlantic Ocean crossing three biogeographic provi...
Seasonal Changes in N2 Fixation Activity and N Enrichment in Paddy Soils as Affected by Soil Management in the Northern Area of Japan
gluten index PCR marker
2009/9/10
We studied single seed descent lines derived from the Kitakeiharu 717 (KKS 717) / Grandin cross. The presence of a B subunit of KKS 717-specific low-molecular-weight-glutenin subunit (LMW-GS) signific...
Difference in δ15N Signatures among Plant Parts of Perennial Species Subjected to Drought Stress with Special Reference to the Contribution of Symbiotic N2-fixation to Plant N
Actinorhizal plant δ15N 15N natural abundance method Nitrogen fixation Perennial plant
2009/7/24
The 15N natural abundance method has been widely used for evaluation of symbiotic N2-fixation. The method inevitably requires a reference plant that reflects soil derived δ15N similar to that in a N2-...
Seasonality of N2 fixation and nifH gene diversity in the Gulf of Aqaba (Red Sea)
N2 fixation nifH gene diversity
2014/4/17
Nitrogen (N2) fixation rates were determined on bulk water collected in the Gulf of Aqaba, Red Sea, during
fall (stratified, oligotrophic) and spring (deep mixing, mesotrophic) seasons. N2
fixation ...
Interactions between changing pCO2, N2 fixation, and Fe limitation in the marine unicellular cyanobacterium Crocosphaera
Interactions between changing pCO2 N2 fixation, Fe limitation in the marine unicellular cyanobacterium Crocosphaera
2014/4/21
We examined the physiological responses of steady-state iron (Fe)-replete and Fe-limited cultures of the biogeochemically critical marine unicellular diazotrophic cyanobacterium Crocosphaera at glacia...
Seasonal dynamics of new production from Trichodesmium N2 fixation and nitrate uptake in the upstream Kuroshio and South China Sea basin
Seasonal dynamics Trichodesmium N2 fixation
2014/4/21
The seasonal dynamics of primary production in the upstream Kuroshio was studied to understand why
pelagic fish are relatively populous in this oligotrophic tropical ocean region. The relative import...

Spatial variation in N2-fixation rate and diazotroph activity in the Tropical Atlantic
Spatial variation N2-fixation rate diazotroph activity Tropical Atlantic
2010/1/14
A variety of N2-fixers occur in oligotrophic waters and these diazotrophs make a substantial contribution to the nitrogen budget of the upper water column. A synthesis of previously published and new ...
CO2 control of Trichodesmium N2 fixation, photosynthesis, growth rates, and elemental ratios: Implications for past, present, and future ocean biogeochemistry
CO2 control Trichodesmium N2 fixation photosynthesis growth rates elemental ratios past present future ocean biogeochemistry
2014/4/22
Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of the new nitrogen entering the oligotrophic oceans, but little is known about how they respond to shifts in g...
The effects of grazing by the snail, Lymnaea elodes, on benthic N2 fixation and primary production in oligotrophic, arctic lakes
snail Lymnaea elodes on benthic N2 fixation primary production oligotrophic arctic lakes
2014/4/21
This study assessed whether grazing by the snail, Lymnaea elodes, limits benthic dinitrogen (N2) fixation and primary production in nitrogen (N)-limited oligotrophic lakes near Toolik Field Station on...
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...
Maximum rates of N2 fixation and primary production are out of phase in a developing cyanobacterial bloom in the Baltic Sea
N2 fixation primary production in a developing cyanobacterial bloom Baltic Sea
2014/5/26
Although N2-fixing cyanobacteria contribute significantly to oceanic sequestration of atmospheric CO2, little is known about how N2 fixation and carbon fixation (primary production) interact in natura...
