How widespread is cyanobacterial colonization of mosses?

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

Many common moss species are colonized by nitrogen fixing cyanobacteria, especially in unpolluted ecosystems. Here, they are important contributors to the ecosystem N budget. But how widespread this colonization by cyanobacteria is, is unknown. Are rare species similarly colonized? In this project, we will screen a wide range of different moss species (20-30) collected across Europe for cyanobacterial colonization and nitrogen fixation activity.  

Methods used:Acetylene reduction assay (gas chromatography), microscopy, culturing, biogeochemical analyses
Keywords:moss, cyanobacteria, nitrogen, symbiosis
