What is it about?
We looked at which microbes were present in the soil above different stages of permafrost thaw from intact permafrost through to fully thawed (not present). We also examined the structure and diversity of these communities. We also compared all these results to the chemical data from the soil and to greenhouse gas emissions from the sites to find out if any of the microbes, or properties of the overall community were connected.
