Abstract
The mechanistic basis of feather moss–cyanobacteria associations, a main driver of nitrogen(N) input into boreal forests, remains unknown. Here, we studied colonization by Nostoc sp. on
two feather mosses that form these associations (Pleurozium schreberi and Hylocomiumsplendens) and two acrocarpous mosses that do not (Dicranum polysetum and Polytrichum
commune). We also determined how N availability and moss reproductive stage affectscolonization, and measured N transfer from cyanobacteria to mosses.
