Eukaryotes in Arctic and Antarctic cyanobacterial mats.

Cyanobacterial mats are commonly found in freshwater ecosystems throughout the polar regions. Most mats are multilayered three-dimensional structures with the filamentous cyanobacteria embedded in a gel-like matrix. Although early descriptions mentioned the presence of larger organisms including metazoans living in the mats, there have been few studies specifically focused on the microbial euka...

Microbial diversity in hot spring cyanobacterial mats: pattern and prediction

Direct molecular analysis of the composition and structure of geothermal cyanobacterial mat communities has revealed diversity patterns suggesting that adaptive radiation and geographic isolation are the important drivers of cyanobacterial diversification. It is clear that 16S rRNA sequence variation cannot detect all ecological or geographic populations (ecotypes and geotypes, respectively), b...

Microsensor measurements of hydrogen gas dynamics in cyanobacterial microbial mats

We used a novel amperometric microsensor for measuring hydrogen gas production and consumption at high spatio-temporal resolution in cyanobacterial biofilms and mats dominated by non-heterocystous filamentous cyanobacteria (Microcoleus chtonoplastes and Oscillatoria sp.). The new microsensor is based on the use of an organic electrolyte and a stable internal reference system and can be equipped...
