summary In this review some aspects of the physiological ecology of cyanobacteria are
discussed by taking a microbial mat as an example. The majority of microbial mats are built …

Cyanobacterial–bacterial consortial associations are taxonomically complex, metabolically
interactive, self‐sustaining prokaryotic communities representing pioneer and often the only …

N limitation to primary production and other ecosystem processes is widespread. To
understand the causes and distribution of N limitation, we must understand the controls of …

Microbial mats occur in nature as stratified communities of cyanobacteria and bacteria, but
they can be cultured on large-scale and manipulated for a variety of functions. They are …

The diversity of nitrogenase genes in a marine cyanobacterial mat was investigated through
amplification of a fragment of nifH, which encodes the Fe protein of the nitrogenase complex …

Nitrogen fixation, a prokaryotic, O2-inhibited process that reduces N2 gas to biomass, is of
paramount importance in biogeochemical cycling of nitrogen. We analyzed the levels of nif …

Stromatolites are laminated, lithified (CaCO3) sedimentary deposits formed by precipitation
and/or sediment accretion by cyanobacterial–bacterial mat communities. Stromatolites have …

To understand the mechanisms responsible for seasonal fluctuations in growth and N2
fixation in intertidal microbial mat communties, we quantified seasonal changes in mat …

Four microbial mat-forming, non-axenic, strains of the non-heterocystous, filamentous,
cyanobacterial genus Microcoleus were maintained in culture and examined for the ability to …

Few measurements of nitrogen fixation exist for streams. Desertstreams are warm, well
lighted, and often supportabundant cyanobacterial populations; thus N 2 fixationmay be …
