Ricardo Alves, Melina Kerou, Anna Zappe, Romana Bittner, Sophie Abby, Harald Schmidt, Kevin Pfeifer and Christa Schleper have a new publication in Frontiers in microbiology, "Ammonia Oxidation by the Arctic Terrestrial Thaumarchaeote Candidatus Nitrosocosmicus arcticus Is Stimulated by Increasing Temperatures".

Climate change is causing arctic regions to warm disproportionally faster than those at lower latitudes, leading to alterations in carbon and nitrogen cycling, and potentially higher greenhouse gas emissions. It is thus increasingly important to better characterize the microorganisms driving arctic biogeochemical processes and their potential responses to changing conditions.
Christa and her team found out that increasing temperatures might drastically affect nitrification in arctic soils by stimulating archaeal ammonia oxidation.
