Together with vegetation ecologists in the International Tundra Experiment (ITEX) network we investigated if long-term warming affects bacterial and fungal communities and their nitrogen (N) cycling capacity in the litter layer across 16 alpine and tundra environments, and how that may impact nitrogen cycling in the underlying soil. The work was led by Mathilde Jeanbille, a former postdoc in my group and now at INRAE. She found that although local conditions rather than warming had an impact on the microbes, warming indirectly modified microbial communities and capacity for N transformations through changes in litter quantity and quality (dominance of herbs), which in turn modified soil nitrogen cycling.
