The contribution of mosses to the carbon and water exchange of arctic ecosystems: quantification and relationships with system properties
ABSTRACT Water vapour and CO 2 exchange were measured in moss‐dominated vegetation using a gas analyser and a 0.3 × 0.3 m chamber at 17 sites near Abisko, Northern Sweden and 21 sites near Longyearbyen, Svalbard, to quantify the contribution of mosses to ecosystem level fluxes. With the help of a si...
