32. Ecology and genomics of microorganisms reducing the greenhouse gas N₂O : examples from the rhizosphere
Sammanfattning : Nitrous oxide (N₂O) is a potent greenhouse gas and the major ozone depleting substance in the stratosphere. One major source of N₂O is incomplete denitrification, whereas the only known tropospheric sink of N₂O is the microbial enzyme nitrous oxide reductase. LÄS MER
33. The role of sediments in nitrogen cycling in the larger Baltic Sea
Sammanfattning : The eutrophication of coastal areas has become a widespread problem over the last decades. In the Baltic Sea, the input of nitrogen and phosphorus has increased by four and eight times, respectively, since the turn of the century, and this is considered the direct cause of the eutrophication of this ecosystem.

34. Ecology of fungal denitrifiers in terrestrial ecosystems : global patterns and effects of management in agricultural soils
Sammanfattning : Denitrification is the dominant source of nitrous oxide (N2O) from terrestrial ecosystems, a potent greenhouse gas and stratospheric ozone-depleting agent. Fungi can perform denitrification and terminate the process with N2O, making them a potentially important source of N2O. LÄS MER
35. Nitrogen removal by wetlands in a cold climate : understanding interactions between macrophytes and microorganisms
Sammanfattning : Nitrogen (N), a fundamental component of living organisms, has become one of the main global concerns for human society due to the myriad of negative effects of excessive N on ecosystems. Anthropogenic activities such as agriculture, industrial production, urbanisation and mining are major sources of N to freshwaters. LÄS MER
