How widespread is cyanobacterial colonization of mosses?

Målgruppe:Biology, Biochemistry
Niveau:Bachelor, Masters

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.
