The BCCM/ULC collection to conserve the biodiversity and study the secondary metabolites of Polar cyanobacteria
In the Polar Regions, Cyanobacteria are the key primary producers and main drivers of the food webs in a wide range of aquatic to terrestrial habitats. For example, they build benthic microbial mats in lakes and soil crusts. Their success in these harsh cold conditions can probably be explained by p...

In the Polar Regions, Cyanobacteria are the key primary producers and main drivers of the food webs in a wide range of aquatic to terrestrial habitats.
