Mosses are a major component of the arctic vegetation, particularly of wetlands. We present C/N ratio, d13C and d15N data of 400 moss samples belonging to 10 species that were collected along hydrological gradients within polygonal mires located on the southern Taymyr Peninsula and the Lena River de...
