Description
Plant productivity in pristine ecosystems like boreal and tropical cloud forests is limited by soil nutrients, primarily nitrogen (N). Mosses are major contributors to ecosystem productivity in these habitats, and most of them are colonized by N2-fixing cyanobacteria, thereby providing N to the ecosystem. Despite this key role, critical knowledge gaps exist. In particular, the climatic controls of moss-associated N2 fixation remain unclear, limiting our ability to quantify and project climate change effects on this fundamental ecosystem function. Further, it is unknown whether mosses and associated cyanobacteria share a mutualistic (both partners benefit) or par...
