Nitrogen fixation and release of fixed nitrogen by Trichodesmium spp. in the Gulf of Mexico
Nitrogen fixation release fixed nitrogen Trichodesmium spp. Gulf of Mexico
2014/5/4
During a 3-yr study in the Gulf of Mexico, we measured dinitrogen (N2) fixation and nitrogen (N) release by Trichodesmium and compared these rates with water column N demand and the estimated N necess...
Iron requirements for dinitrogen- and ammonium-supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron:carbon ratios of field populations
Iron requirements nitrogen- and ammonium-supported growth cultures of Trichodesmium nitrogen fixation rates and iron field populations
2014/5/21
We quantified the relationships among the specific growth rate, intracellular iron content, and steady state iron uptake rate for cultures of the marine diazotrophic cyanobacterium Trichodesmium (IMS ...
Stimulation of nitrogen fixation in refractory organic sediments by Caulerpa taxifolia (Chlorophyta)
Stimulation of nitrogen fixation refractory organic sediments Caulerpa taxifolia Chlorophyta
2014/5/20
Estimates of N2 fixation by substrata associated with the rhizophytic alga Caulerpa taxifolia were obtained using the acetylene reduction method. On average, growth of C. taxifolia enhanced rates of a...
Iron availability, cellular iron quotas, and nitrogen fixation in Trichodesmium
Iron availability cellular iron quotas nitrogen fixation Trichodesmium
2014/6/9
Iron availability is suggested to be a primary factor limiting nitrogen fixation in the oceans. This hypothesis is principally based on cost-benefit analyses of iron quotas in the dominant nitrogen-fi...
Baltic Sea nitrogen fixation estimated from the summer increase in upper mixed layer total nitrogen
Baltic Sea nitrogen fixation the summer increase upper mixed layer total nitrogen
2014/6/9
We estimated nitrogen fixation from the increase in total nitrogen (N2 gas excluded) in the upper 20 m during the summer biomass increase of heterocystous filamentous cyanobacteria at the off-shore La...
Epilithic nitrogen fixation in the rocky littoral zones of Lake Malawi, Africa
Epilithic nitrogen fixation rocky littoral zones Lake Malawi Africa
2014/6/9
Rates of epilithic N2 fixation in the rocky littoral zones of Lake Malawi, determined by in situ incubations and the acetylene reduction method, declined with depth, were highly correlated to light in...
