Extended Data Fig. 2: Landscapes of the three thermo-erosion gullies and views of warming experiments at the Shaliuhe site.
From: Enhanced response of soil respiration to experimental warming upon thermokarst formation
a-c, Photographs of the three thermo-erosion gullies at the Shaliuhe site. d,e, Overall views of warming experiments in non-collapsed (d) and collapsed (e) areas from panel (a). f, A photo showing the warming treatment on the vegetated patch. The open-top chambers were built within the vegetated patches in the collapsed plots, which were formed by the fragmentation of the soil surface upon permafrost collapse. Given that the upper soil was protected by mattic epipedon which had an intensive root network protecting the soil against interference58,59, these vegetated patches maintained their original soil structure, despite the translocation of the exposed soil upon permafrost collapse13.
