Diazotrophic unicellular cyanobacteria in the northwestern Mediterranean Sea: A seasonal cycle
Diazotrophic unicellular cyanobacteria
2014/4/18
Unicellular diazotrophic cyanobacteria (UCYN2-Fix lineage) were detected using whole-cell hybridization of
specific Nitro821 oligonucleotide probe at the coastal and oligotrophic station SOMLIT off M...
Colimitation of the unicellular photosynthetic diazotroph Crocosphaera watsonii by phosphorus, light, and carbon dioxide
Colimitation unicellular photosynthetic diazotroph Crocosphaera watsonii phosphorus, light carbon dioxide
2014/4/2
We describe interactive effects of total phosphorus (total P = 0.1–4.0 μmol L−1; added as H2NaPO4), irradiance (40 and 150 μmol quanta m−2 s−1), and the partial pressure of carbon di...
Ammonium uptake and dinitrogen fixation by the unicellular nanocyanobacterium Crocosphaera watsonii in nitrogen-limited continuous cultures
nanocyanobacterium Crocosphaera Ammonium uptake
2014/4/2
Ammonium uptake and nitrogen (N) fixation of the unicellular nanocyanobacterium Crocosphaera watsonii
isolated from the western subtropical North Pacific were determined in N-limited continuous cultu...
An analogue of the Harer-Zagier formula for unicellular maps on general surfaces
the Harer-Zagier formula unicellular maps on general surfaces
2010/11/15
A unicellular map is the embedding of a connected graph in a surface in such a way that the complement of the graph is simply connected. In a famous article, Harer and Zagier established a formula fo...
A complete unitary similarity invariant for unicellular matrices
invariant unicellular matrices
2010/11/8
Necessary and sufficient conditions for two n-by-n unicellular complex matrices to be unitarily equivalent are established.

The cyanate utilization capacity of marine unicellular Cyanobacteria
The cyanate utilization capacity marine unicellular Cyanobacteria
2014/4/21
Cyanate, a by-product of urea decomposition, is a potential nitrogen (N) source in marine environments, but to date it has received scant attention. Cyanobacteria presumably acquire this compound via ...
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...

Competition and facilitation between unicellular nitrogen-fixing cyanobacteria and non–nitrogen-fixing phytoplankton species
Competition facilitation unicellular nitrogen-fixing
2014/4/22
Recent discoveries show that small unicellular nitrogen-fixing cyanobacteria are more widespread than
previously thought and can make major contributions to the nitrogen budget of the oceans. We comb...
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean
Nitrogen fixation unicellular diazotrophic cyanobacteria temperate oligotrophic North Pacific Ocean
2014/4/22
N2 fixation has been understudied in marine environments outside of the subtropical and tropical oceans and where water temperatures are typically below 20-25°C. We identified nifH phylotypes and meas...
