Experimental Evidence that Fungi are Dominant Microbes in Carbon Content and Growth Response to Added Soluble Organic Carbon in Moss‐rich Tundra Soil
Abstract Global warming significantly affects Arctic tundra, including permafrost thaw and soluble C release that may differentially affect tundra microbial growth. Using laboratory experiments, we report some of the first evidence for the effects of soluble glucose‐C enrichment on tundra soil proka...

Summary: | Abstract Global warming significantly affects Arctic tundra, including permafrost thaw and soluble C release that may differentially affect tundra microbial growth. Using laboratory experiments, we report some of the first evidence for the effects of soluble glucose‐C enrichment on tundra soil prokaryotes (bacteria and archaea) and fungi, with comparisons to microbial eukaryotes. Fungal increase in C‐biomass was equivalent to 10% (w/w) of the added glucose‐C, and for prokaryote biomass 2% (w/w), the latter comparable to prior published results. The C‐gain after 14 d was 1.3 mg/g soil for fungi, and ~200 μg/g for prokaryotes. |
