Climate change effects on moss-associated N fixation

Main area:Ecology
Target group:Biology
Educational level:Masters, Bachelor
Project description:

Mosses are colonized by nitrogen (N) fixing bacteria (mostly cyanobacteria) in unpolluted ecosystems like subarctic tundra, boreal forests and tropical cloud forests. But we do not know how climate change will affect the key ecosystem process of moss-associated nitrogen fixation. We use different approaches and methods to assess the effects of increased temperature, change in precipitation patterns etc. on N fixation performed by cyanobacteria colonizing mosses in natural ecosystems.

Methods used:nitrogen fixation measurements, microscopy, nutrient analyses
Keywords:mosses, cyanobacteria , climate change, nitrogen
