Soil organic matter quality influences mineralization and GHG emissions in cryosols: a field-based study of sub- to high Arctic.

abstract：:Global climate change is affecting carbon cycling by driving changes in primary productivity and rates of carbon fixation, release and storage within Earth's vegetated systems. There is, however, limited understanding of how carbon flow between donor and recipient habitats will respond to climatic changes. Macroalgal-...
