Diversity and nitrogen fixation activity of cyanobacterial communities in terrestrial arctic ecosystems

Updated 2003-01-27

Biological nitrogen fixation by cyanobacteria is a key process for productivity in terrestrial Arctic ecosystems and the activity is dependent of size and diversity of cyanobacterial populations. Changes in biodiversity after pertubations of different types of habitats simulating climatic changes or other antropogenic effects will be studied by molecular methods and correlated to variations of nitrogen fixation activity.
