Increases in temperature and nutrient availability positively affect methane-cycling microorganisms in Arctic thermokarst lake sediments
Arctic permafrost soils store large amounts of organic matter that is sensitive to temperature increases and subsequent microbial degradation to methane (CH 4 ) and carbon dioxide (CO 2 ). Here, we studied methanogenic and methanotrophic activity and community composition in thermokarst lake sedimen...
