Nitrogen deposition caused by human activities can lead to an increased phytoplankton production in boreal lakes. The response of boreal lakes to nitrogen deposition will strongly depend on each lake’s content of organic carbon, which are predicted to increase with future warmer and wetter climate. This according to a thesis at Umeå University.
The worldwide increase of inorganic nitrogen deposition via fossil fuel combustion, fertilization and forestry has been intervening drastically with the Earths’ natural nitrogen cycle. Food webs of boreal lakes, that have historically received little nitrogen deposition until now, are expected to be especially susceptible to increases in inorganic nitrogen availability.
